  77         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
  78         now the tests are run in private dirs, therefore AC_CLEANUP and
  79         family can be simplified to 0-ary.
  80         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
  81         use abs. path to find config.h.
  82         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
  83         stderr, there can be way too much random noise.
  84         Instead pass -Werror to GCC and rely on the exit status.
  85         Reported by Wolfram Wagner.
  86
  87 2001-11-14  Akim Demaille  <akim@epita.fr>
  88
  89         * src/bison.simple (yyparse): Let yyls1, yyss1 and yyvs1 be
  90         defined only if yyoverflow is defined, to avoid `warning: unused
  91         variable `yyvs1''.
  92         Reported by The Test Suite.

  94 2001-11-14  Akim Demaille  <akim@epita.fr>

 100
 101         * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
 102         Revert a previous patch:  these are really const.
 103         * src/conflicts.c (conflict_report): Additional useless pair of
 104         braces to pacify GCC's warnings for `if () if () {} else {}'.
 105         * src/lex.c (parse_percent_token): Replace equal_offset with
 106         arg_offset.
 107         arg is const.
 108         Be sure to strdup `arg' when used, since there is no reason for
 109         token_buffer not to change.

 112

 119

1475         Get rid of the ad hoc handling of token_buffer in the scanner: use
1476         the obstacks.
1477
1478         * src/lex.c (token_obstack): New.
1479         (init_lex): Initialize it.  No longer call...
1480         (grow_token_buffer): this.  Remove it.

1482
1483 2001-01-19  Akim Demaille  <akim@epita.fr>
1484
1485         * src/lex.h: Rename all the tokens:

1487         s/\bIDENTIFIER\b/tok_identifier/g;

1502         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

1507         * src/reader.c (read_declarations): Adjust.
1508         * src/files.c (open_files): Don't call `compute_base_names', don't
1509         compute `attrsfile' since they depend upon data which might be
1510         *in* the input file now.
1511         (output_files): Do it here.
1512         * src/output.c (output_headers): Document the fact that this patch
1513         introduces a guaranteed SEGV for semantic parsers.

1539
1540 2000-12-20  Akim Demaille  <akim@epita.fr>
1541
1542         * src/files.c (open_files): Actually the `.output' file is based

1545
1546 2000-12-20  Akim Demaille  <akim@epita.fr>

1596
1597         Let the handling of the skeleton files be local to the procedures
1598         that use it.
1599

1616
1617         * src/files.c (open_files): Yipee!  We no longer need all the code

1649         * lib/obstack.h: Formatting changes.
1650         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
1651         prevents type checking.
1652         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
1653         cast the value to (void *): assigning a `foo *' to a `void *'

1738         when there are no errors.
1739

1842
1843         When a literal string is used to define two different tokens,
1844         `bison -v' segfaults.
1845         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
1846
1847         * tests/regression.m4: New file.
1848         Include the core of the sample provided by Piotr Gackiewicz.
1849         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
1850         properly.
1851

1853
1854         * src/reader.c (parse_expect_decl): Keep `count' within the size
1855         of `buffer'.

1857
1858 2000-10-02  Paul Eggert  <eggert@twinsun.com>
1859
1860         * bison.s1 (yyparse): Assign the default value
1861         unconditionally, to avoid a GCC warning and make the parser a
1862         tad smaller.
1863
1864 2000-10-02  Akim Demaille  <akim@epita.fr>
1865
1866         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
1867         options.
1868
1869 2000-10-02  Akim Demaille  <akim@epita.fr>
1870
1871         * src/derives.c, src/print.c, src/reduce.c: To ease the
1872         translation, move some `\n' out of the translated strings.
1873
1874 2000-10-02  Akim Demaille  <akim@epita.fr>
1875
1876         The location tracking mechanism is precious for parse error
1877         messages.  Nevertheless, it is enabled only when `@n' is used in
1878         the grammar, which is a different issue (you can use it in error
1879         message, but not in the grammar per se).  Therefore, there should
1880         be another means to enable it.
1881
1882         * src/getargs.c (getargs): Support `--locations'.
1883         (usage): Report it.
1884         * src/getargs.h (locationsflag): Export it.
1885         * src/lex.c (percent_table): Support `%locations'.
1886         * src/reader.c (yylsp_needed): Remove this variable, now replaced
1887         with `locationsflag'.
1888         * doc/bison.texinfo: Document `--locations' and `%locations'.
1889         Sort the options.
1890         * tests/calc.m4: Test it.
1891
1892         For regularity of the names, replace each
1893         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
1894         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
1895         In addition replace each `flag' with `_flag'.
1896
1897 2000-10-02  Akim Demaille  <akim@epita.fr>
1898
1899         Also test parse error messages, including with YYERROR_VERBOSE.
1900
1901         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
1902         associative).
1903         Use it to check the computations.
1904         Use it to check `nonassoc' is honored.
1905         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
1906         `--yyerror-verbose'.
1907         (_AT_CHECK_CALC): Adjust to this option.
1908         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
1909
1910 2000-10-02  Akim Demaille  <akim@epita.fr>
1911
1912         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
1913         the latter demonstrates a flaw in the handling of non debugging
1914         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
1915         was used in order to simplify:
1916
1917         #if YYDEBUG
1918         if (yydebug)
1919         {
1920         ...
1921         }
1922         #endif
1923
1924         into
1925
1926         if (yydebug)
1927         {
1928         ...
1929         }
1930
1931         unfortunately this leads to a CPP conflict when
1932         `--name-prefix=foo' is used since it produces `#define yydebug
1933         foodebug'.
1934
1935         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
1936         (YYDPRINTF): New macro.
1937         Spread its use.
1938         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
1939         the bison options.
1940         Also test `--verbose', `--defines' and `--name-prefix'.
1941
1942 2000-10-02  Akim Demaille  <akim@epita.fr>
1943
1944         Improve the readability of the produced parsers.
1945
1946         * src/bison.s1: Formatting changes.
1947         Improve the comment related to the `$' mark.
1948         (yydefault): Don't fall through to `yyresume': `goto' there.
1949         * src/output.c (output_parser): When the `$' is met, skip the end
1950         of its line.
1951         New variable, `number_of_dollar_signs', to check there's exactly
1952         one `$' in the parser skeleton.
1953
1954 2000-10-02  Akim Demaille  <akim@epita.fr>
1955
1956         * lib/xstrdup.c: New file, from the fileutils.
1957         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
1958         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
1959         instead of strlen + xmalloc + strcpy.
1960         * src/symtab.c (copys): Remove, use xstrdup instead.
1961
1962 2000-10-02  Akim Demaille  <akim@epita.fr>
1963
1964         * src/gram.h (associativity): New enum type which replaces the
1965         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
1966         `right_assoc', `left_assoc' and `non_assoc'.
1967         Adjust all dependencies.
1968         * src/reader.c: Formatting changes.
1969         (LTYPESTR): Don't define it, use it as a literal in
1970         `reader_output_yylsp'.
1971         * src/symtab.h (symbol_class): New enum type which replaces the
1972         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
1973         `sunknown', `stoken and `snterm'.
1974
1975 2000-10-02  Akim Demaille  <akim@epita.fr>
1976
1977         * src/getargs.c (fixed_outfiles): Rename as...
1978         (yaccflag): for consistency and accuracy.
1979         Adjust dependencies.
1980
1981 2000-10-02  Akim Demaille  <akim@epita.fr>
1982
1983         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
1984         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
1985         difficult and introduced a lot of core dump.  It turns out that
1986         Bison used an implementation of `xmalloc' based on `calloc', and
1987         at various places it does depend upon the initialization to 0.  I
1988         have not tried to isolate the pertinent places, and all the former
1989         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
1990         someone should address this issue.
1991
1992         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
1993         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

2086
2087         * src/output.c (token_actions): Introduce a temporary array,

2090
2091 2000-10-02  Akim Demaille  <akim@epita.fr>
2092
2093         `user_toknums' is output as a `short[]' in `output.c', while it is
2094         defined as a `int[]' in `reader.c'.  For consistency with the
2095         other output tables, `user_toknums' is now defined as a table of
2096         shorts.
2097
2098         * src/reader.c (user_toknums): Be a short table instead of an int

2111         order to get rid of the `static' prototypes.

2113         * src/output.h: New file.
2114         Propagate its inclusion in files explicitly prototyping functions

2138         Don't define PARAMS.
2139         * src/system.h: Define PARAMS.
2140         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
2141         purpose of config.h.  system.h must not try to fix wrong
2142         definitions in config.h.

2305
2306 2000-03-17  Akim Demaille  <akim@epita.fr>
2307
2308         On syntax errors, report the token on which we choked.

2330         copy_comment.  Removed now unused `match', `ended',
2331         `cplus_comment'.
2332         (copy_comment, copy_string): Moved, to be visible from
2333         copy_definition.
2334

2336

2359
2360         Change the handling of @s so that they behave exactly like $s.
2361         There is now a pseudo variable @$ (readble and writable), location
2362         of the lhs of the rule (by default ranging from the location of
2363         the first symbol of the rhs, to the location of the last symbol,
2364         or, if the rhs is empty, YYLLOC).
2365
2366         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2367         yyval.
2368         (yyparse): When providing a default semantic action, provide a
2369         default location action.
2370         (after the $): No longer change `*YYLSP', just stack YYLOC the
2371         same way you stack YYVAL.
2372         * src/reader.c (read_declarations): Use warns.
2373         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2374         (copy_action, case '@'): Likewise.
2375         Use a standard error message, to save useless work from
2376         translators.
2377
2378 2000-03-17  Akim Demaille  <akim@epita.fr>
2379

2397
2398         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
2399         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2400         One `#if YYDEBUG' remains, since it uses variables which are
2401         defined only if `YYDEBUG != 0'.
2402
2403 2000-03-16  Akim Demaille  <akim@epita.fr>
2404
2405         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

2427         handled via src/Makefile.am.

2429         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

2435         the proper line number and file name.
2436         (DEFS): Propagate the location of bison library files and of the
2437         locale files.
2438         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
2439         builddir.
2440         * acinclude.m4: Remove, replaced by the directory m4.
2441         * m4/Makefile.am (EXTRA_DIST): New variable.
2442         * m4/gettext.m4: New file, from the fileutils.

3129         major changes to files.c.
