 125         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
 126         now the tests are run in private dirs, therefore AC_CLEANUP and
 127         family can be simplified to 0-ary.
 128         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
 129         use abs. path to find config.h.
 130         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
 131         stderr, there can be way too much random noise.

 133         Reported by Wolfram Wagner.
 134
 135 2001-11-14  Akim Demaille  <akim@epita.fr>
 136
 137         * src/bison.simple (yyparse): Let yyls1, yyss1 and yyvs1 be
 138         defined only if yyoverflow is defined, to avoid `warning: unused
 139         variable `yyvs1''.
 140         Reported by The Test Suite.

 142 2001-11-14  Akim Demaille  <akim@epita.fr>

 148
 149         * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
 150         Revert a previous patch:  these are really const.
 151         * src/conflicts.c (conflict_report): Additional useless pair of
 152         braces to pacify GCC's warnings for `if () if () {} else {}'.
 153         * src/lex.c (parse_percent_token): Replace equal_offset with
 154         arg_offset.
 155         arg is const.
 156         Be sure to strdup `arg' when used, since there is no reason for
 157         token_buffer not to change.

 160

 164         Suggested by Hans Aberg.
 165
 166 2001-11-12  Akim Demaille  <akim@epita.fr>
 167
 168         * src/system.h (ngettext): Now that we use ngettext, be sure to
 169         provide a default definition when NLS are not used.

 190         * configure.in (AM_GNU_GETTEXT): Ask for ngettext.

 294         Promote `-' over `_' in directive names.

1466 2001-07-14  Akim Demaille  <akim@epita.fr>
1467
1468         * config/: New.
1469         * configure.in: Require Autoconf 2.50.
1470         Update to gettext 0.10.38.
1471
1472 2001-03-16  Akim Demaille  <akim@epita.fr>
1473
1474         * doc/bison.texinfo: ANSIfy the examples.
1475
1476 2001-03-16  Akim Demaille  <akim@epita.fr>
1477
1478         * getargs.c (skeleton): New variable.
1479         (longopts): --skeleton is a new option.
1480         (shortopts, getargs): -S is a new option.
1481         * getargs.h: Declare skeleton.
1482         * output.c (output_parser): Use it.
1483
1484 2001-03-16  Akim Demaille  <akim@epita.fr>
1485
1486         * m4/strerror_r.m4: New.
1487         * m4/error.m4: Run AC_FUNC_STRERROR_R.

1489
1490 2001-03-16  Akim Demaille  <akim@epita.fr>

1493
1494 2001-02-21  Akim Demaille  <akim@epita.fr>
1495
1496         * src/reader.c (gensym): `gensym_count' is your own.
1497         Use a static buf to create the symbol name, as token_buffer is no
1498         longer a buffer.
1499
1500 2001-02-08  Akim Demaille  <akim@epita.fr>
1501
1502         * src/conflicts.c (conflict_report): Be sure not to append to res
1503         between two calls, which could happen if both first sprintf were
1504         skipped, but not the first cp += strlen.
1505
1506 2001-02-08  Akim Demaille  <akim@epita.fr>
1507
1508         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
1509         New, from fileutils 4.0.37.
1510         * configure.in: Require Autoconf 2.49c.  I took some time before
1511         making this decision.  This is the only way out for portability
1512         issues in Bison, it would mean way too much duplicate effort to
1513         import in Bison features implemented in 2.49c since 2.13.
1514         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
1515
1516 2001-02-02  Akim Demaille  <akim@epita.fr>
1517
1518         * lib/malloc.c, lib/realloc.c: New, from the fileutils 4.0.37.

1520
1521 2001-01-19  Akim Demaille  <akim@epita.fr>
1522
1523         Get rid of the ad hoc handling of token_buffer in the scanner: use
1524         the obstacks.
1525
1526         * src/lex.c (token_obstack): New.
1527         (init_lex): Initialize it.  No longer call...
1528         (grow_token_buffer): this.  Remove it.
1529         Adjust all the places which used it to use the obstack.
1530
1531 2001-01-19  Akim Demaille  <akim@epita.fr>
1532
1533         * src/lex.h: Rename all the tokens:
1534         s/\bENDFILE\b/tok_eof/g;
1535         s/\bIDENTIFIER\b/tok_identifier/g;
1536         etc.
1537         Let them be enums, not #define, to ease debugging.
1538         Adjust all the code.
1539
1540 2001-01-18  Akim Demaille  <akim@epita.fr>
1541
1542         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
1543         * src/lex.c (maxtoken, grow_token_buffer): Static.
1544
1545 2001-01-18  Akim Demaille  <akim@epita.fr>
1546
1547         Since we now use obstacks, more % directives can be enabled.
1548
1549         * src/lex.c (percent_table): Also accept `%yacc',
1550         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
1551         `%debug'.
1552         Handle the actions for `%semantic_parser' and `%pure_parser' here,
1553         instead of returning a token.
1554         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
1555         * src/reader.c (read_declarations): Adjust.
1556         * src/files.c (open_files): Don't call `compute_base_names', don't
1557         compute `attrsfile' since they depend upon data which might be
1558         *in* the input file now.
1559         (output_files): Do it here.
1560         * src/output.c (output_headers): Document the fact that this patch
1561         introduces a guaranteed SEGV for semantic parsers.
1562         * doc/bison.texinfo: Document them.
1563         * tests/suite.at: Exercise these %options.
1564
1565 2000-12-20  Akim Demaille  <akim@epita.fr>
1566
1567         Also handle the output file (--verbose) with obstacks.
1568
1569         * files.c (foutput): Remove.
1570         (output_obstack): New.
1571         Adjust all dependencies.
1572         * src/conflicts.c: Return a string.
1573         * src/system.h (obstack_grow_string): Rename as...
1574         (obstack_sgrow): this.  Be ready to work with non literals.

1578
1579         * src/files.c (open_files): Fix the computation of short_base_name
1580         in the case of `-o foo.tab.c'.
1581
1582 2000-12-20  Akim Demaille  <akim@epita.fr>
1583
1584         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
1585         (copy_dollar): Now that everything uses obstacks, get rid of the
1586         FILE * parameters.
1587
1588 2000-12-20  Akim Demaille  <akim@epita.fr>
1589
1590         * src/files.c (open_files): Actually the `.output' file is based
1591         on the short_base_name, not base_name.
1592         * tests/suite.at (Checking output file names): Adjust.
1593
1594 2000-12-20  Akim Demaille  <akim@epita.fr>
1595
1596         * src/bison.s1: Remove, we now use directly...
1597         * src/bison.simple: this.
1598         * src/Makefile.am: Use pkgdata instead of data.
1599

1613         (output_files): Adjust.
1614         (base_name, short_base_name): Be global.
1615         Adjust dependencies.
1616
1617 2000-12-19  Akim Demaille  <akim@epita.fr>
1618
1619         * src/files.c (strsuffix): New.
1620         (stringappend): Be just like strcat but allocate.
1621         (base_names): Eve out from open_files.
1622         Try to simplify the rather hairy computation of base_name and
1623         short_base_name.
1624         (open_files): Use it.
1625         * tests/suite.at (Checking output file names): New test.

1632         `$'.
1633         * src/bison.s1: s/$/%% actions/.
1634         * src/bison.hairy: Likewise.
1635
1636 2000-12-19  Akim Demaille  <akim@epita.fr>
1637
1638         * src/output.c (output_parser): Compute the `#line' lines when
1639         there are.
1640         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
1641         Suggested by Hans Aberg.
1642
1643 2000-12-19  Akim Demaille  <akim@epita.fr>
1644
1645         Let the handling of the skeleton files be local to the procedures
1646         that use it.
1647
1648         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
1649         longer static.
1650         (fparser, open_extra_files): Remove.

1659

1663 2000-12-19  Akim Demaille  <akim@epita.fr>
1664
1665         * src/files.c (open_files): Yipee!  We no longer need all the code
1666         looking for `/tmp' since we have no tmp file.
1667
1668 2000-12-19  Akim Demaille  <akim@epita.fr>
1669
1670         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

1696
1697         * lib/obstack.h: Formatting changes.
1698         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
1699         prevents type checking.
1700         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
1701         cast the value to (void *): assigning a `foo *' to a `void *'
1702         variable is valid.
1703         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
1704         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

1720
1721         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New

1739
1740 2000-11-07  Akim Demaille  <akim@epita.fr>
1741
1742         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
1743         Merge in a single CPP if/else.
1744
1745 2000-11-07  Akim Demaille  <akim@epita.fr>
1746
1747         * src/output.c (output): Remove useless variables.
1748         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
1749         argument `data' for consistency with the prototypes.
1750         Qualify it `const'.
1751         (obstack_copy, obstack_copy0): Rename the second argument as
1752         `address' for consistency.  Qualify it `const'.

1754         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
1755         `const' their input argument (`data' or `address').

1758 2000-11-03  Akim Demaille  <akim@epita.fr>
1759

1762         Adjust dependencies.
1763
1764 2000-11-03  Akim Demaille  <akim@epita.fr>
1765
1766         For some reason, this was not applied.
1767
1768         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

1772

1783         Use `obstack_save'.
1784         * src/main.c (main): Don't use `atexit' to register `done', since
1785         it no longer has to remove tmp files, just call `output_files'
1786         when there are no errors.
1787
1788 2000-11-02  Akim Demaille  <akim@epita.fr>
1789
1790         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

1901
1902         * src/reader.c (parse_expect_decl): Keep `count' within the size
1903         of `buffer'.
1904         From Neil Booth.
1905
1906 2000-10-02  Paul Eggert  <eggert@twinsun.com>
1907
1908         * bison.s1 (yyparse): Assign the default value
1909         unconditionally, to avoid a GCC warning and make the parser a
1910         tad smaller.
1911
1912 2000-10-02  Akim Demaille  <akim@epita.fr>
1913

1921
1922 2000-10-02  Akim Demaille  <akim@epita.fr>
1923
1924         The location tracking mechanism is precious for parse error
1925         messages.  Nevertheless, it is enabled only when `@n' is used in
1926         the grammar, which is a different issue (you can use it in error
1927         message, but not in the grammar per se).  Therefore, there should
1928         be another means to enable it.
1929
1930         * src/getargs.c (getargs): Support `--locations'.
1931         (usage): Report it.
1932         * src/getargs.h (locationsflag): Export it.
1933         * src/lex.c (percent_table): Support `%locations'.
1934         * src/reader.c (yylsp_needed): Remove this variable, now replaced
1935         with `locationsflag'.
1936         * doc/bison.texinfo: Document `--locations' and `%locations'.
1937         Sort the options.
1938         * tests/calc.m4: Test it.
1939
1940         For regularity of the names, replace each
1941         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
1942         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
1943         In addition replace each `flag' with `_flag'.
1944
1945 2000-10-02  Akim Demaille  <akim@epita.fr>
1946
1947         Also test parse error messages, including with YYERROR_VERBOSE.
1948
1949         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
1950         associative).
1951         Use it to check the computations.
1952         Use it to check `nonassoc' is honored.
1953         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
1954         `--yyerror-verbose'.
1955         (_AT_CHECK_CALC): Adjust to this option.
1956         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
1957
1958 2000-10-02  Akim Demaille  <akim@epita.fr>
1959
1960         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
1961         the latter demonstrates a flaw in the handling of non debugging
1962         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
1963         was used in order to simplify:
1964
1965         #if YYDEBUG
1966         if (yydebug)
1967         {
1968         ...
1969         }
1970         #endif
1971
1972         into
1973
1974         if (yydebug)
1975         {
1976         ...
1977         }
1978
1979         unfortunately this leads to a CPP conflict when
1980         `--name-prefix=foo' is used since it produces `#define yydebug
1981         foodebug'.
1982
1983         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
1984         (YYDPRINTF): New macro.
1985         Spread its use.
1986         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
1987         the bison options.
1988         Also test `--verbose', `--defines' and `--name-prefix'.
1989
1990 2000-10-02  Akim Demaille  <akim@epita.fr>
1991
1992         Improve the readability of the produced parsers.
1993
1994         * src/bison.s1: Formatting changes.
1995         Improve the comment related to the `$' mark.
1996         (yydefault): Don't fall through to `yyresume': `goto' there.
1997         * src/output.c (output_parser): When the `$' is met, skip the end
1998         of its line.
1999         New variable, `number_of_dollar_signs', to check there's exactly
2000         one `$' in the parser skeleton.
2001
2002 2000-10-02  Akim Demaille  <akim@epita.fr>
2003
2004         * lib/xstrdup.c: New file, from the fileutils.
2005         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
2006         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
2007         instead of strlen + xmalloc + strcpy.
2008         * src/symtab.c (copys): Remove, use xstrdup instead.
2009
2010 2000-10-02  Akim Demaille  <akim@epita.fr>
2011
2012         * src/gram.h (associativity): New enum type which replaces the
2013         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
2014         `right_assoc', `left_assoc' and `non_assoc'.
2015         Adjust all dependencies.
2016         * src/reader.c: Formatting changes.
2017         (LTYPESTR): Don't define it, use it as a literal in
2018         `reader_output_yylsp'.
2019         * src/symtab.h (symbol_class): New enum type which replaces the
2020         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
2021         `sunknown', `stoken and `snterm'.
2022
2023 2000-10-02  Akim Demaille  <akim@epita.fr>
2024
2025         * src/getargs.c (fixed_outfiles): Rename as...
2026         (yaccflag): for consistency and accuracy.
2027         Adjust dependencies.
2028
2029 2000-10-02  Akim Demaille  <akim@epita.fr>
2030
2031         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
2032         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
2033         difficult and introduced a lot of core dump.  It turns out that
2034         Bison used an implementation of `xmalloc' based on `calloc', and
2035         at various places it does depend upon the initialization to 0.  I
2036         have not tried to isolate the pertinent places, and all the former
2037         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
2038         someone should address this issue.
2039
2040         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
2041         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

2047 2000-10-02  Akim Demaille  <akim@epita.fr>
2048
2049         Various anti-`extern in *.c' changes.

2052
2053 2000-10-02  Akim Demaille  <akim@epita.fr>
2054
2055         * src/state.h (nstates, final_state, first_state, first_shift)

2133 2000-10-02  Akim Demaille  <akim@epita.fr>
2134
2135         * src/output.c (token_actions): Introduce a temporary array,

2137         output_short_table.
2138
2139 2000-10-02  Akim Demaille  <akim@epita.fr>
2140
2141         `user_toknums' is output as a `short[]' in `output.c', while it is
2142         defined as a `int[]' in `reader.c'.  For consistency with the
2143         other output tables, `user_toknums' is now defined as a table of
2144         shorts.
2145
2146         * src/reader.c (user_toknums): Be a short table instead of an int

2159         order to get rid of the `static' prototypes.
2160         No longer use `register'.
2161         * src/output.h: New file.

2172         * src/closure.c: Formatting changes, topological sort over the
2173         functions, use of closure.h.
2174         (initialize_closure, finalize_closure):  Rename as...
2175         (new_closure, free_closure): these.  Adjust dependencies.

2185         inclusion.
2186         Don't define PARAMS.
2187         * src/system.h: Define PARAMS.
2188         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

2190         definitions in config.h.

2327         * configure.in: Adjust.
2328         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's

2352         the file name, not the whole `#line LINE FILE'.
2353
2354 2000-03-17  Akim Demaille  <akim@epita.fr>
2355
2356         On syntax errors, report the token on which we choked.
2357
2358         * src/bison.s1 (yyparse): In the label yyerrlab, when

2376

2378         copy_comment.  Removed now unused `match', `ended',
2379         `cplus_comment'.
2380         (copy_comment, copy_string): Moved, to be visible from
2381         copy_definition.

2384

2407
2408         Change the handling of @s so that they behave exactly like $s.
2409         There is now a pseudo variable @$ (readble and writable), location
2410         of the lhs of the rule (by default ranging from the location of
2411         the first symbol of the rhs, to the location of the last symbol,
2412         or, if the rhs is empty, YYLLOC).
2413
2414         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2415         yyval.
2416         (yyparse): When providing a default semantic action, provide a
2417         default location action.
2418         (after the $): No longer change `*YYLSP', just stack YYLOC the
2419         same way you stack YYVAL.
2420         * src/reader.c (read_declarations): Use warns.
2421         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2422         (copy_action, case '@'): Likewise.
2423         Use a standard error message, to save useless work from
2424         translators.
2425
2426 2000-03-17  Akim Demaille  <akim@epita.fr>

2445
2446         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
2447         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2448         One `#if YYDEBUG' remains, since it uses variables which are
2449         defined only if `YYDEBUG != 0'.
2450
2451 2000-03-16  Akim Demaille  <akim@epita.fr>
2452
2453         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

2477         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

2483         the proper line number and file name.
2484         (DEFS): Propagate the location of bison library files and of the
2485         locale files.
2486         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
2487         builddir.
2488         * acinclude.m4: Remove, replaced by the directory m4.
2489         * m4/Makefile.am (EXTRA_DIST): New variable.
