  66         * tests/calc.at, tests/output.at, tests/regression.at,
  67         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
  68         now the tests are run in private dirs, therefore AC_CLEANUP and
  69         family can be simplified to 0-ary.
  70         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
  71         use abs. path to find config.h.
  72         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
  73         stderr, there can be way too much random noise.
  74         Instead pass -Werror to GCC and rely on the exit status.
  75         Reported by Wolfram Wagner.
  76
  77 2001-11-14  Akim Demaille  <akim@epita.fr>
  78
  79         * src/bison.simple (yyparse): Let yyls1, yyss1 and yyvs1 be
  80         defined only if yyoverflow is defined, to avoid `warning: unused
  81         variable `yyvs1''.
  82         Reported by The Test Suite.
  83
  84 2001-11-14  Akim Demaille  <akim@epita.fr>

  90
  91         * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
  92         Revert a previous patch:  these are really const.
  93         * src/conflicts.c (conflict_report): Additional useless pair of
  94         braces to pacify GCC's warnings for `if () if () {} else {}'.
  95         * src/lex.c (parse_percent_token): Replace equal_offset with
  96         arg_offset.
  97         arg is const.
  98         Be sure to strdup `arg' when used, since there is no reason for
  99         token_buffer not to change.

 101 2001-11-14  Akim Demaille  <akim@epita.fr>
 102

 106         Suggested by Hans Aberg.

 109
 110         * src/system.h (ngettext): Now that we use ngettext, be sure to

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

1466         the obstacks.
1467
1468         * src/lex.c (token_obstack): New.
1469         (init_lex): Initialize it.  No longer call...

1472

1474
1475         * src/lex.h: Rename all the tokens:

1477         s/\bIDENTIFIER\b/tok_identifier/g;
1478         etc.
1479         Let them be enums, not #define, to ease debugging.

1489         Since we now use obstacks, more % directives can be enabled.
1490
1491         * src/lex.c (percent_table): Also accept `%yacc',
1492         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

1497         * src/reader.c (read_declarations): Adjust.
1498         * src/files.c (open_files): Don't call `compute_base_names', don't
1499         compute `attrsfile' since they depend upon data which might be
1500         *in* the input file now.
1501         (output_files): Do it here.
1502         * src/output.c (output_headers): Document the fact that this patch
1503         introduces a guaranteed SEGV for semantic parsers.
1504         * doc/bison.texinfo: Document them.

1528         FILE * parameters.
1529
1530 2000-12-20  Akim Demaille  <akim@epita.fr>
1531
1532         * src/files.c (open_files): Actually the `.output' file is based
1533         on the short_base_name, not base_name.
1534         * tests/suite.at (Checking output file names): Adjust.
1535
1536 2000-12-20  Akim Demaille  <akim@epita.fr>

1562         (stringappend): Be just like strcat but allocate.
1563         (base_names): Eve out from open_files.

1567         * tests/suite.at (Checking output file names): New test.

1584
1585 2000-12-19  Akim Demaille  <akim@epita.fr>
1586
1587         Let the handling of the skeleton files be local to the procedures
1588         that use it.
1589
1590         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
1591         longer static.

1605 2000-12-19  Akim Demaille  <akim@epita.fr>
1606
1607         * src/files.c (open_files): Yipee!  We no longer need all the code
1608         looking for `/tmp' since we have no tmp file.
1609

1639         * lib/obstack.h: Formatting changes.
1640         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
1641         prevents type checking.
1642         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
1643         cast the value to (void *): assigning a `foo *' to a `void *'
1644         variable is valid.
1645         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
1646         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

1683

1728         when there are no errors.
1729

1832
1833         When a literal string is used to define two different tokens,
1834         `bison -v' segfaults.
1835         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
1836
1837         * tests/regression.m4: New file.
1838         Include the core of the sample provided by Piotr Gackiewicz.
1839         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
1840         properly.

1843
1844         * src/reader.c (parse_expect_decl): Keep `count' within the size
1845         of `buffer'.
1846         From Neil Booth.
1847
1848 2000-10-02  Paul Eggert  <eggert@twinsun.com>
1849
1850         * bison.s1 (yyparse): Assign the default value
1851         unconditionally, to avoid a GCC warning and make the parser a
1852         tad smaller.
1853
1854 2000-10-02  Akim Demaille  <akim@epita.fr>
1855
1856         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
1857         options.
1858
1859 2000-10-02  Akim Demaille  <akim@epita.fr>
1860
1861         * src/derives.c, src/print.c, src/reduce.c: To ease the
1862         translation, move some `\n' out of the translated strings.
1863
1864 2000-10-02  Akim Demaille  <akim@epita.fr>
1865
1866         The location tracking mechanism is precious for parse error
1867         messages.  Nevertheless, it is enabled only when `@n' is used in
1868         the grammar, which is a different issue (you can use it in error
1869         message, but not in the grammar per se).  Therefore, there should
1870         be another means to enable it.
1871
1872         * src/getargs.c (getargs): Support `--locations'.
1873         (usage): Report it.
1874         * src/getargs.h (locationsflag): Export it.
1875         * src/lex.c (percent_table): Support `%locations'.
1876         * src/reader.c (yylsp_needed): Remove this variable, now replaced
1877         with `locationsflag'.
1878         * doc/bison.texinfo: Document `--locations' and `%locations'.
1879         Sort the options.
1880         * tests/calc.m4: Test it.
1881
1882         For regularity of the names, replace each
1883         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
1884         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
1885         In addition replace each `flag' with `_flag'.
1886
1887 2000-10-02  Akim Demaille  <akim@epita.fr>
1888
1889         Also test parse error messages, including with YYERROR_VERBOSE.
1890
1891         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
1892         associative).
1893         Use it to check the computations.
1894         Use it to check `nonassoc' is honored.
1895         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
1896         `--yyerror-verbose'.
1897         (_AT_CHECK_CALC): Adjust to this option.
1898         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
1899
1900 2000-10-02  Akim Demaille  <akim@epita.fr>
1901
1902         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
1903         the latter demonstrates a flaw in the handling of non debugging
1904         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
1905         was used in order to simplify:
1906
1907         #if YYDEBUG
1908         if (yydebug)
1909         {
1910         ...
1911         }
1912         #endif
1913
1914         into
1915
1916         if (yydebug)
1917         {
1918         ...
1919         }
1920
1921         unfortunately this leads to a CPP conflict when
1922         `--name-prefix=foo' is used since it produces `#define yydebug
1923         foodebug'.
1924
1925         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
1926         (YYDPRINTF): New macro.
1927         Spread its use.
1928         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
1929         the bison options.
1930         Also test `--verbose', `--defines' and `--name-prefix'.
1931
1932 2000-10-02  Akim Demaille  <akim@epita.fr>
1933
1934         Improve the readability of the produced parsers.
1935
1936         * src/bison.s1: Formatting changes.
1937         Improve the comment related to the `$' mark.
1938         (yydefault): Don't fall through to `yyresume': `goto' there.
1939         * src/output.c (output_parser): When the `$' is met, skip the end
1940         of its line.
1941         New variable, `number_of_dollar_signs', to check there's exactly
1942         one `$' in the parser skeleton.
1943
1944 2000-10-02  Akim Demaille  <akim@epita.fr>
1945
1946         * lib/xstrdup.c: New file, from the fileutils.
1947         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
1948         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
1949         instead of strlen + xmalloc + strcpy.
1950         * src/symtab.c (copys): Remove, use xstrdup instead.
1951
1952 2000-10-02  Akim Demaille  <akim@epita.fr>
1953
1954         * src/gram.h (associativity): New enum type which replaces the
1955         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
1956         `right_assoc', `left_assoc' and `non_assoc'.
1957         Adjust all dependencies.
1958         * src/reader.c: Formatting changes.
1959         (LTYPESTR): Don't define it, use it as a literal in
1960         `reader_output_yylsp'.
1961         * src/symtab.h (symbol_class): New enum type which replaces the
1962         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
1963         `sunknown', `stoken and `snterm'.
1964
1965 2000-10-02  Akim Demaille  <akim@epita.fr>
1966
1967         * src/getargs.c (fixed_outfiles): Rename as...
1968         (yaccflag): for consistency and accuracy.
1969         Adjust dependencies.
1970
1971 2000-10-02  Akim Demaille  <akim@epita.fr>
1972
1973         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
1974         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
1975         difficult and introduced a lot of core dump.  It turns out that
1976         Bison used an implementation of `xmalloc' based on `calloc', and
1977         at various places it does depend upon the initialization to 0.  I
1978         have not tried to isolate the pertinent places, and all the former
1979         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
1980         someone should address this issue.
1981
1982         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
1983         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
1984         files.

1994
1995 2000-10-02  Akim Demaille  <akim@epita.fr>
1996
1997         * src/state.h (nstates, final_state, first_state, first_shift)

2076
2077         * src/output.c (token_actions): Introduce a temporary array,

2079         output_short_table.
2080
2081 2000-10-02  Akim Demaille  <akim@epita.fr>
2082
2083         `user_toknums' is output as a `short[]' in `output.c', while it is
2084         defined as a `int[]' in `reader.c'.  For consistency with the
2085         other output tables, `user_toknums' is now defined as a table of
2086         shorts.
2087
2088         * src/reader.c (user_toknums): Be a short table instead of an int

2101         order to get rid of the `static' prototypes.
2102         No longer use `register'.
2103         * src/output.h: New file.
2104         Propagate its inclusion in files explicitly prototyping functions
2105         from output.c.

2127         inclusion.
2128         Don't define PARAMS.
2129         * src/system.h: Define PARAMS.
2130         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
2131         purpose of config.h.  system.h must not try to fix wrong
2132         definitions in config.h.

2172
2173         * configure.in: Append WARNING_CFLAGS to CFLAGS.

2294         the file name, not the whole `#line LINE FILE'.
2295
2296 2000-03-17  Akim Demaille  <akim@epita.fr>
2297
2298         On syntax errors, report the token on which we choked.
2299
2300         * src/bison.s1 (yyparse): In the label yyerrlab, when

2318

2320         copy_comment.  Removed now unused `match', `ended',
2321         `cplus_comment'.
2322         (copy_comment, copy_string): Moved, to be visible from
2323         copy_definition.

2326

2349
2350         Change the handling of @s so that they behave exactly like $s.
2351         There is now a pseudo variable @$ (readble and writable), location
2352         of the lhs of the rule (by default ranging from the location of
2353         the first symbol of the rhs, to the location of the last symbol,
2354         or, if the rhs is empty, YYLLOC).
2355
2356         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2357         yyval.
2358         (yyparse): When providing a default semantic action, provide a
2359         default location action.
2360         (after the $): No longer change `*YYLSP', just stack YYLOC the
2361         same way you stack YYVAL.
2362         * src/reader.c (read_declarations): Use warns.
2363         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2364         (copy_action, case '@'): Likewise.
2365         Use a standard error message, to save useless work from
2366         translators.
2367
2368 2000-03-17  Akim Demaille  <akim@epita.fr>
2369

2387
2388         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
2389         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2390         One `#if YYDEBUG' remains, since it uses variables which are
2391         defined only if `YYDEBUG != 0'.
2392
2393 2000-03-16  Akim Demaille  <akim@epita.fr>
2394
2395         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

2417         handled via src/Makefile.am.

2419         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

2425         the proper line number and file name.
2426         (DEFS): Propagate the location of bison library files and of the
2427         locale files.
2428         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
2429         builddir.
2430         * acinclude.m4: Remove, replaced by the directory m4.
2431         * m4/Makefile.am (EXTRA_DIST): New variable.
2432         * m4/gettext.m4: New file, from the fileutils.

3119         major changes to files.c.
3120         (lex) Retain in the incoming stream a character following
3121         an incorrect '/'.
