  44
  45         * src/lalr.h (state_t): New.

  56         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
  57         now the tests are run in private dirs, therefore AC_CLEANUP and
  58         family can be simplified to 0-ary.
  59         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
  60         use abs. path to find config.h.
  61         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
  62         stderr, there can be way too much random noise.
  63         Instead pass -Werror to GCC and rely on the exit status.
  64         Reported by Wolfram Wagner.
  65
  66 2001-11-14  Akim Demaille  <akim@epita.fr>
  67
  68         * src/bison.simple (yyparse): Let yyls1, yyss1 and yyvs1 be
  69         defined only if yyoverflow is defined, to avoid `warning: unused
  70         variable `yyvs1''.
  71         Reported by The Test Suite.
  72
  73 2001-11-14  Akim Demaille  <akim@epita.fr>

  79
  80         * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
  81         Revert a previous patch:  these are really const.
  82         * src/conflicts.c (conflict_report): Additional useless pair of
  83         braces to pacify GCC's warnings for `if () if () {} else {}'.
  84         * src/lex.c (parse_percent_token): Replace equal_offset with
  85         arg_offset.
  86         arg is const.
  87         Be sure to strdup `arg' when used, since there is no reason for
  88         token_buffer not to change.

  91

  95         Suggested by Hans Aberg.

  98
  99         * src/system.h (ngettext): Now that we use ngettext, be sure to
 100         provide a default definition when NLS are not used.

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

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

1478         Since we now use obstacks, more % directives can be enabled.
1479
1480         * src/lex.c (percent_table): Also accept `%yacc',
1481         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

1486         * src/reader.c (read_declarations): Adjust.
1487         * src/files.c (open_files): Don't call `compute_base_names', don't

1489         *in* the input file now.
1490         (output_files): Do it here.
1491         * src/output.c (output_headers): Document the fact that this patch

1517         FILE * parameters.
1518
1519 2000-12-20  Akim Demaille  <akim@epita.fr>
1520
1521         * src/files.c (open_files): Actually the `.output' file is based

1524
1525 2000-12-20  Akim Demaille  <akim@epita.fr>

1551         (stringappend): Be just like strcat but allocate.
1552         (base_names): Eve out from open_files.

1556         * tests/suite.at (Checking output file names): New test.

1574 2000-12-19  Akim Demaille  <akim@epita.fr>
1575
1576         Let the handling of the skeleton files be local to the procedures
1577         that use it.
1578
1579         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
1580         longer static.

1594 2000-12-19  Akim Demaille  <akim@epita.fr>
1595
1596         * src/files.c (open_files): Yipee!  We no longer need all the code
1597         looking for `/tmp' since we have no tmp file.
1598

1628         * lib/obstack.h: Formatting changes.
1629         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
1630         prevents type checking.
1631         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
1632         cast the value to (void *): assigning a `foo *' to a `void *'
1633         variable is valid.
1634         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

1670
1671 2000-11-07  Akim Demaille  <akim@epita.fr>
1672

1715         * src/main.c (main): Don't use `atexit' to register `done', since
1716         it no longer has to remove tmp files, just call `output_files'
1717         when there are no errors.
1718

1823         `bison -v' segfaults.
1824         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
1825
1826         * tests/regression.m4: New file.
1827         Include the core of the sample provided by Piotr Gackiewicz.
1828         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
1829         properly.
1830
1831 2000-10-04  Akim Demaille  <akim@epita.fr>
1832
1833         * src/reader.c (parse_expect_decl): Keep `count' within the size
1834         of `buffer'.
1835         From Neil Booth.
1836
1837 2000-10-02  Paul Eggert  <eggert@twinsun.com>
1838
1839         * bison.s1 (yyparse): Assign the default value
1840         unconditionally, to avoid a GCC warning and make the parser a
1841         tad smaller.
1842
1843 2000-10-02  Akim Demaille  <akim@epita.fr>
1844
1845         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
1846         options.
1847
1848 2000-10-02  Akim Demaille  <akim@epita.fr>
1849
1850         * src/derives.c, src/print.c, src/reduce.c: To ease the
1851         translation, move some `\n' out of the translated strings.
1852
1853 2000-10-02  Akim Demaille  <akim@epita.fr>
1854
1855         The location tracking mechanism is precious for parse error
1856         messages.  Nevertheless, it is enabled only when `@n' is used in
1857         the grammar, which is a different issue (you can use it in error
1858         message, but not in the grammar per se).  Therefore, there should
1859         be another means to enable it.
1860
1861         * src/getargs.c (getargs): Support `--locations'.
1862         (usage): Report it.
1863         * src/getargs.h (locationsflag): Export it.
1864         * src/lex.c (percent_table): Support `%locations'.
1865         * src/reader.c (yylsp_needed): Remove this variable, now replaced
1866         with `locationsflag'.
1867         * doc/bison.texinfo: Document `--locations' and `%locations'.
1868         Sort the options.
1869         * tests/calc.m4: Test it.
1870
1871         For regularity of the names, replace each
1872         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
1873         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
1874         In addition replace each `flag' with `_flag'.
1875
1876 2000-10-02  Akim Demaille  <akim@epita.fr>
1877
1878         Also test parse error messages, including with YYERROR_VERBOSE.
1879
1880         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
1881         associative).
1882         Use it to check the computations.
1883         Use it to check `nonassoc' is honored.
1884         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
1885         `--yyerror-verbose'.
1886         (_AT_CHECK_CALC): Adjust to this option.
1887         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
1888
1889 2000-10-02  Akim Demaille  <akim@epita.fr>
1890
1891         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
1892         the latter demonstrates a flaw in the handling of non debugging
1893         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
1894         was used in order to simplify:
1895
1896         #if YYDEBUG
1897         if (yydebug)
1898         {
1899         ...
1900         }
1901         #endif
1902
1903         into
1904
1905         if (yydebug)
1906         {
1907         ...
1908         }
1909
1910         unfortunately this leads to a CPP conflict when
1911         `--name-prefix=foo' is used since it produces `#define yydebug
1912         foodebug'.
1913
1914         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
1915         (YYDPRINTF): New macro.
1916         Spread its use.
1917         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
1918         the bison options.
1919         Also test `--verbose', `--defines' and `--name-prefix'.
1920
1921 2000-10-02  Akim Demaille  <akim@epita.fr>
1922
1923         Improve the readability of the produced parsers.
1924
1925         * src/bison.s1: Formatting changes.
1926         Improve the comment related to the `$' mark.
1927         (yydefault): Don't fall through to `yyresume': `goto' there.
1928         * src/output.c (output_parser): When the `$' is met, skip the end
1929         of its line.
1930         New variable, `number_of_dollar_signs', to check there's exactly
1931         one `$' in the parser skeleton.
1932
1933 2000-10-02  Akim Demaille  <akim@epita.fr>
1934
1935         * lib/xstrdup.c: New file, from the fileutils.
1936         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
1937         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
1938         instead of strlen + xmalloc + strcpy.
1939         * src/symtab.c (copys): Remove, use xstrdup instead.
1940
1941 2000-10-02  Akim Demaille  <akim@epita.fr>
1942
1943         * src/gram.h (associativity): New enum type which replaces the
1944         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
1945         `right_assoc', `left_assoc' and `non_assoc'.
1946         Adjust all dependencies.
1947         * src/reader.c: Formatting changes.
1948         (LTYPESTR): Don't define it, use it as a literal in
1949         `reader_output_yylsp'.
1950         * src/symtab.h (symbol_class): New enum type which replaces the
1951         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
1952         `sunknown', `stoken and `snterm'.
1953
1954 2000-10-02  Akim Demaille  <akim@epita.fr>
1955
1956         * src/getargs.c (fixed_outfiles): Rename as...
1957         (yaccflag): for consistency and accuracy.
1958         Adjust dependencies.
1959
1960 2000-10-02  Akim Demaille  <akim@epita.fr>
1961
1962         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
1963         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
1964         difficult and introduced a lot of core dump.  It turns out that
1965         Bison used an implementation of `xmalloc' based on `calloc', and
1966         at various places it does depend upon the initialization to 0.  I
1967         have not tried to isolate the pertinent places, and all the former
1968         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
1969         someone should address this issue.
1970
1971         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
1972         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
1973         files.

1978 2000-10-02  Akim Demaille  <akim@epita.fr>
1979
1980         Various anti-`extern in *.c' changes.

1983
1984 2000-10-02  Akim Demaille  <akim@epita.fr>
1985
1986         * src/state.h (nstates, final_state, first_state, first_shift)

1988         * src/LR0.h: to here.
1989         Adjust dependencies.
1990         * src/getargs.c (statisticsflag): New variable.

2064 2000-10-02  Akim Demaille  <akim@epita.fr>
2065
2066         * src/output.c (token_actions): Introduce a temporary array,

2068         output_short_table.
2069
2070 2000-10-02  Akim Demaille  <akim@epita.fr>
2071
2072         `user_toknums' is output as a `short[]' in `output.c', while it is
2073         defined as a `int[]' in `reader.c'.  For consistency with the
2074         other output tables, `user_toknums' is now defined as a table of
2075         shorts.
2076
2077         * src/reader.c (user_toknums): Be a short table instead of an int
2078         table.

2088
2089         * src/output.c (output): Topological sort of the functions, in
2090         order to get rid of the `static' prototypes.
2091         No longer use `register'.
2092         * src/output.h: New file.
2093         Propagate its inclusion in files explicitly prototyping functions
2094         from output.c.

2116         inclusion.
2117         Don't define PARAMS.
2118         * src/system.h: Define PARAMS.
2119         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
2120         purpose of config.h.  system.h must not try to fix wrong
2121         definitions in config.h.

2161

2283         the file name, not the whole `#line LINE FILE'.
2284
2285 2000-03-17  Akim Demaille  <akim@epita.fr>
2286
2287         On syntax errors, report the token on which we choked.
2288
2289         * src/bison.s1 (yyparse): In the label yyerrlab, when

2309         copy_comment.  Removed now unused `match', `ended',
2310         `cplus_comment'.
2311         (copy_comment, copy_string): Moved, to be visible from
2312         copy_definition.
2313

2315
2316         * src/reader.c (copy_string): Declare `static inline'.  No

2338
2339         Change the handling of @s so that they behave exactly like $s.
2340         There is now a pseudo variable @$ (readble and writable), location
2341         of the lhs of the rule (by default ranging from the location of
2342         the first symbol of the rhs, to the location of the last symbol,
2343         or, if the rhs is empty, YYLLOC).
2344
2345         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2346         yyval.
2347         (yyparse): When providing a default semantic action, provide a
2348         default location action.
2349         (after the $): No longer change `*YYLSP', just stack YYLOC the
2350         same way you stack YYVAL.
2351         * src/reader.c (read_declarations): Use warns.
2352         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2353         (copy_action, case '@'): Likewise.
2354         Use a standard error message, to save useless work from
2355         translators.
2356
2357 2000-03-17  Akim Demaille  <akim@epita.fr>
2358
2359         * src/bison.s1: Formatting and cosmetics changes.

2376
2377         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
2378         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2379         One `#if YYDEBUG' remains, since it uses variables which are
2380         defined only if `YYDEBUG != 0'.
2381
2382 2000-03-16  Akim Demaille  <akim@epita.fr>
2383
2384         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

2406         handled via src/Makefile.am.

2408         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
2409         autoheader.

2414         the proper line number and file name.
2415         (DEFS): Propagate the location of bison library files and of the
2416         locale files.
2417         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
2418         builddir.
2419         * acinclude.m4: Remove, replaced by the directory m4.
2420         * m4/Makefile.am (EXTRA_DIST): New variable.
2421         * m4/gettext.m4: New file, from the fileutils.
