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

 141         Reported by Wolfram Wagner.
 142
 143 2001-11-14  Akim Demaille  <akim@epita.fr>
 144
 145         * src/bison.simple (yyparse): Let yyls1, yyss1 and yyvs1 be
 146         defined only if yyoverflow is defined, to avoid `warning: unused
 147         variable `yyvs1''.

 150 2001-11-14  Akim Demaille  <akim@epita.fr>

 156
 157         * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
 158         Revert a previous patch:  these are really const.
 159         * src/conflicts.c (conflict_report): Additional useless pair of
 160         braces to pacify GCC's warnings for `if () if () {} else {}'.
 161         * src/lex.c (parse_percent_token): Replace equal_offset with
 162         arg_offset.
 163         arg is const.
 164         Be sure to strdup `arg' when used, since there is no reason for
 165         token_buffer not to change.
 166
 167 2001-11-14  Akim Demaille  <akim@epita.fr>
 168

 175
 176         * src/system.h (ngettext): Now that we use ngettext, be sure to
 177         provide a default definition when NLS are not used.

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

 302         Promote `-' over `_' in directive names.
 303         (Bison Options): s/%locactions/%locations/.  Nice Freudian slip.
 304         Simplify the description of `--name-prefix'.

1470         * src/lex.c (parse_percent_token): Die on `%raw'.
1471         * src/reader.c (output_token_defines): Suppress call to `raw_flag'.
1472         * tests/calc.at: Suppress test with option `--raw'.
1473
1474 2001-07-14  Akim Demaille  <akim@epita.fr>
1475
1476         * config/: New.
1477         * configure.in: Require Autoconf 2.50.
1478         Update to gettext 0.10.38.
1479
1480 2001-03-16  Akim Demaille  <akim@epita.fr>
1481
1482         * doc/bison.texinfo: ANSIfy the examples.
1483
1484 2001-03-16  Akim Demaille  <akim@epita.fr>
1485
1486         * getargs.c (skeleton): New variable.
1487         (longopts): --skeleton is a new option.
1488         (shortopts, getargs): -S is a new option.
1489         * getargs.h: Declare skeleton.
1490         * output.c (output_parser): Use it.
1491
1492 2001-03-16  Akim Demaille  <akim@epita.fr>
1493
1494         * m4/strerror_r.m4: New.
1495         * m4/error.m4: Run AC_FUNC_STRERROR_R.
1496         * lib/error.h, lib/error.c: Update.
1497
1498 2001-03-16  Akim Demaille  <akim@epita.fr>

1500         * src/getargs.c (longopts): Clean up.
1501
1502 2001-02-21  Akim Demaille  <akim@epita.fr>
1503
1504         * src/reader.c (gensym): `gensym_count' is your own.
1505         Use a static buf to create the symbol name, as token_buffer is no
1506         longer a buffer.
1507
1508 2001-02-08  Akim Demaille  <akim@epita.fr>
1509
1510         * src/conflicts.c (conflict_report): Be sure not to append to res
1511         between two calls, which could happen if both first sprintf were
1512         skipped, but not the first cp += strlen.
1513
1514 2001-02-08  Akim Demaille  <akim@epita.fr>
1515
1516         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
1517         New, from fileutils 4.0.37.
1518         * configure.in: Require Autoconf 2.49c.  I took some time before
1519         making this decision.  This is the only way out for portability
1520         issues in Bison, it would mean way too much duplicate effort to
1521         import in Bison features implemented in 2.49c since 2.13.
1522         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
1523
1524 2001-02-02  Akim Demaille  <akim@epita.fr>
1525
1526         * lib/malloc.c, lib/realloc.c: New, from the fileutils 4.0.37.

1528
1529 2001-01-19  Akim Demaille  <akim@epita.fr>
1530
1531         Get rid of the ad hoc handling of token_buffer in the scanner: use
1532         the obstacks.
1533
1534         * src/lex.c (token_obstack): New.
1535         (init_lex): Initialize it.  No longer call...
1536         (grow_token_buffer): this.  Remove it.
1537         Adjust all the places which used it to use the obstack.
1538
1539 2001-01-19  Akim Demaille  <akim@epita.fr>
1540
1541         * src/lex.h: Rename all the tokens:
1542         s/\bENDFILE\b/tok_eof/g;
1543         s/\bIDENTIFIER\b/tok_identifier/g;
1544         etc.
1545         Let them be enums, not #define, to ease debugging.
1546         Adjust all the code.
1547
1548 2001-01-18  Akim Demaille  <akim@epita.fr>
1549
1550         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
1551         * src/lex.c (maxtoken, grow_token_buffer): Static.
1552
1553 2001-01-18  Akim Demaille  <akim@epita.fr>
1554
1555         Since we now use obstacks, more % directives can be enabled.
1556
1557         * src/lex.c (percent_table): Also accept `%yacc',
1558         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
1559         `%debug'.
1560         Handle the actions for `%semantic_parser' and `%pure_parser' here,
1561         instead of returning a token.
1562         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
1563         * src/reader.c (read_declarations): Adjust.
1564         * src/files.c (open_files): Don't call `compute_base_names', don't
1565         compute `attrsfile' since they depend upon data which might be
1566         *in* the input file now.
1567         (output_files): Do it here.
1568         * src/output.c (output_headers): Document the fact that this patch
1569         introduces a guaranteed SEGV for semantic parsers.
1570         * doc/bison.texinfo: Document them.
1571         * tests/suite.at: Exercise these %options.
1572
1573 2000-12-20  Akim Demaille  <akim@epita.fr>
1574
1575         Also handle the output file (--verbose) with obstacks.
1576
1577         * files.c (foutput): Remove.
1578         (output_obstack): New.
1579         Adjust all dependencies.
1580         * src/conflicts.c: Return a string.
1581         * src/system.h (obstack_grow_string): Rename as...
1582         (obstack_sgrow): this.  Be ready to work with non literals.
1583         (obstack_fgrow4): New.
1584
1585 2000-12-20  Akim Demaille  <akim@epita.fr>
1586
1587         * src/files.c (open_files): Fix the computation of short_base_name
1588         in the case of `-o foo.tab.c'.
1589
1590 2000-12-20  Akim Demaille  <akim@epita.fr>
1591
1592         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
1593         (copy_dollar): Now that everything uses obstacks, get rid of the
1594         FILE * parameters.
1595
1596 2000-12-20  Akim Demaille  <akim@epita.fr>
1597
1598         * src/files.c (open_files): Actually the `.output' file is based
1599         on the short_base_name, not base_name.
1600         * tests/suite.at (Checking output file names): Adjust.
1601
1602 2000-12-20  Akim Demaille  <akim@epita.fr>
1603
1604         * src/bison.s1: Remove, we now use directly...
1605         * src/bison.simple: this.
1606         * src/Makefile.am: Use pkgdata instead of data.
1607

1619         vars.
1620         (open_files): Don't compute them.
1621         (output_files): Adjust.
1622         (base_name, short_base_name): Be global.
1623         Adjust dependencies.
1624
1625 2000-12-19  Akim Demaille  <akim@epita.fr>
1626
1627         * src/files.c (strsuffix): New.
1628         (stringappend): Be just like strcat but allocate.
1629         (base_names): Eve out from open_files.
1630         Try to simplify the rather hairy computation of base_name and
1631         short_base_name.
1632         (open_files): Use it.
1633         * tests/suite.at (Checking output file names): New test.
1634
1635 2000-12-19  Akim Demaille  <akim@epita.fr>

1640         `$'.
1641         * src/bison.s1: s/$/%% actions/.
1642         * src/bison.hairy: Likewise.
1643
1644 2000-12-19  Akim Demaille  <akim@epita.fr>
1645
1646         * src/output.c (output_parser): Compute the `#line' lines when
1647         there are.
1648         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
1649         Suggested by Hans Aberg.
1650
1651 2000-12-19  Akim Demaille  <akim@epita.fr>
1652
1653         Let the handling of the skeleton files be local to the procedures
1654         that use it.
1655
1656         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
1657         longer static.
1658         (fparser, open_extra_files): Remove.

1667

1670
1671 2000-12-19  Akim Demaille  <akim@epita.fr>
1672
1673         * src/files.c (open_files): Yipee!  We no longer need all the code
1674         looking for `/tmp' since we have no tmp file.
1675
1676 2000-12-19  Akim Demaille  <akim@epita.fr>
1677
1678         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

1699         to escape special characters when outputting filenames.
1700         (ACTSTR_PROLOGUE, ACTSTR_EPILOGUE): Remove.

1704
1705         * lib/obstack.h: Formatting changes.
1706         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
1707         prevents type checking.
1708         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
1709         cast the value to (void *): assigning a `foo *' to a `void *'
1710         variable is valid.
1711         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
1712         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

1728
1729         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New

1747
1748 2000-11-07  Akim Demaille  <akim@epita.fr>
1749
1750         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
1751         Merge in a single CPP if/else.
1752
1753 2000-11-07  Akim Demaille  <akim@epita.fr>
1754
1755         * src/output.c (output): Remove useless variables.
1756         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
1757         argument `data' for consistency with the prototypes.
1758         Qualify it `const'.
1759         (obstack_copy, obstack_copy0): Rename the second argument as
1760         `address' for consistency.  Qualify it `const'.
1761         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
1762         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
1763         `const' their input argument (`data' or `address').
1764         Adjust the corresponding macros to include `const' in casts.
1765
1766 2000-11-03  Akim Demaille  <akim@epita.fr>
1767
1768         * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
1769         s/PFILE1/BISON_HAIRY/.
1770         Adjust dependencies.
1771
1772 2000-11-03  Akim Demaille  <akim@epita.fr>
1773
1774         For some reason, this was not applied.
1775
1776         * src/files.c [VMS]: No longer include `ssdef.h', no longer define
1777         `unlink': it's no longer used.
1778
1779 2000-11-03  Akim Demaille  <akim@epita.fr>
1780
1781         * src/files.c (skeleton_find): New function, eved out of...

1789         (done): Rename as...
1790         (output_files): this.
1791         Use `obstack_save'.
1792         * src/main.c (main): Don't use `atexit' to register `done', since
1793         it no longer has to remove tmp files, just call `output_files'
1794         when there are no errors.
1795
1796 2000-11-02  Akim Demaille  <akim@epita.fr>
1797
1798         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

1900         `bison -v' segfaults.
1901         Reported by Piotr Gackiewicz, and fixed by Neil Booth.

1906         properly.

1909
1910         * src/reader.c (parse_expect_decl): Keep `count' within the size
1911         of `buffer'.
1912         From Neil Booth.
1913
1914 2000-10-02  Paul Eggert  <eggert@twinsun.com>
1915
1916         * bison.s1 (yyparse): Assign the default value
1917         unconditionally, to avoid a GCC warning and make the parser a
1918         tad smaller.
1919
1920 2000-10-02  Akim Demaille  <akim@epita.fr>
1921

1926
1927         * src/derives.c, src/print.c, src/reduce.c: To ease the

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

2035         Adjust dependencies.
2036
2037 2000-10-02  Akim Demaille  <akim@epita.fr>
2038
2039         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
2040         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
2041         difficult and introduced a lot of core dump.  It turns out that
2042         Bison used an implementation of `xmalloc' based on `calloc', and
2043         at various places it does depend upon the initialization to 0.  I
2044         have not tried to isolate the pertinent places, and all the former
2045         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
2046         someone should address this issue.
2047
2048         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
2049         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

2145         output_short_table.
2146
2147 2000-10-02  Akim Demaille  <akim@epita.fr>
2148
2149         `user_toknums' is output as a `short[]' in `output.c', while it is
2150         defined as a `int[]' in `reader.c'.  For consistency with the
2151         other output tables, `user_toknums' is now defined as a table of

2198         definitions in config.h.

2360         the file name, not the whole `#line LINE FILE'.
2361
2362 2000-03-17  Akim Demaille  <akim@epita.fr>
2363
2364         On syntax errors, report the token on which we choked.
2365
2366         * src/bison.s1 (yyparse): In the label yyerrlab, when

2386         copy_comment.  Removed now unused `match', `ended',
2387         `cplus_comment'.
2388         (copy_comment, copy_string): Moved, to be visible from
2389         copy_definition.

2392
2393         * src/reader.c (copy_string): Declare `static inline'.  No

2415
2416         Change the handling of @s so that they behave exactly like $s.
2417         There is now a pseudo variable @$ (readble and writable), location
2418         of the lhs of the rule (by default ranging from the location of
2419         the first symbol of the rhs, to the location of the last symbol,
2420         or, if the rhs is empty, YYLLOC).
2421
2422         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2423         yyval.
2424         (yyparse): When providing a default semantic action, provide a
2425         default location action.
2426         (after the $): No longer change `*YYLSP', just stack YYLOC the
2427         same way you stack YYVAL.
2428         * src/reader.c (read_declarations): Use warns.
2429         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2430         (copy_action, case '@'): Likewise.
2431         Use a standard error message, to save useless work from
2432         translators.
2433
2434 2000-03-17  Akim Demaille  <akim@epita.fr>
2435

2453
2454         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
2455         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2456         One `#if YYDEBUG' remains, since it uses variables which are
2457         defined only if `YYDEBUG != 0'.
2458
2459 2000-03-16  Akim Demaille  <akim@epita.fr>
2460
2461         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

2491         the proper line number and file name.
2492         (DEFS): Propagate the location of bison library files and of the
2493         locale files.
2494         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
2495         builddir.
2496         * acinclude.m4: Remove, replaced by the directory m4.
2497         * m4/Makefile.am (EXTRA_DIST): New variable.
