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

  84
  85         * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
  86         Revert a previous patch:  these are really const.
  87         * src/conflicts.c (conflict_report): Additional useless pair of
  88         braces to pacify GCC's warnings for `if () if () {} else {}'.
  89         * src/lex.c (parse_percent_token): Replace equal_offset with
  90         arg_offset.
  91         arg is const.
  92         Be sure to strdup `arg' when used, since there is no reason for
  93         token_buffer not to change.
  94
  95 2001-11-14  Akim Demaille  <akim@epita.fr>
  96

 100         Suggested by Hans Aberg.

 103
 104         * src/system.h (ngettext): Now that we use ngettext, be sure to
 105         provide a default definition when NLS are not used.

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

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

1103         (output_parser): Use the macro table.

1466
1467 2001-01-19  Akim Demaille  <akim@epita.fr>
1468
1469         * src/lex.h: Rename all the tokens:
1470         s/\bENDFILE\b/tok_eof/g;
1471         s/\bIDENTIFIER\b/tok_identifier/g;
1472         etc.
1473         Let them be enums, not #define, to ease debugging.
1474         Adjust all the code.
1475
1476 2001-01-18  Akim Demaille  <akim@epita.fr>

1481 2001-01-18  Akim Demaille  <akim@epita.fr>
1482
1483         Since we now use obstacks, more % directives can be enabled.
1484
1485         * src/lex.c (percent_table): Also accept `%yacc',
1486         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
1487         `%debug'.
1488         Handle the actions for `%semantic_parser' and `%pure_parser' here,
1489         instead of returning a token.

1491         * src/reader.c (read_declarations): Adjust.
1492         * src/files.c (open_files): Don't call `compute_base_names', don't
1493         compute `attrsfile' since they depend upon data which might be
1494         *in* the input file now.
1495         (output_files): Do it here.
1496         * src/output.c (output_headers): Document the fact that this patch
1497         introduces a guaranteed SEGV for semantic parsers.
1498         * doc/bison.texinfo: Document them.

1522         FILE * parameters.
1523
1524 2000-12-20  Akim Demaille  <akim@epita.fr>
1525
1526         * src/files.c (open_files): Actually the `.output' file is based

1529
1530 2000-12-20  Akim Demaille  <akim@epita.fr>

1556         (stringappend): Be just like strcat but allocate.
1557         (base_names): Eve out from open_files.

1560         (open_files): Use it.
1561         * tests/suite.at (Checking output file names): New test.

1578
1579 2000-12-19  Akim Demaille  <akim@epita.fr>
1580
1581         Let the handling of the skeleton files be local to the procedures
1582         that use it.
1583
1584         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
1585         longer static.

1598
1599 2000-12-19  Akim Demaille  <akim@epita.fr>
1600
1601         * src/files.c (open_files): Yipee!  We no longer need all the code
1602         looking for `/tmp' since we have no tmp file.
1603
1604 2000-12-19  Akim Demaille  <akim@epita.fr>
1605
1606         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

1633         * lib/obstack.h: Formatting changes.
1634         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
1635         prevents type checking.
1636         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
1637         cast the value to (void *): assigning a `foo *' to a `void *'
1638         variable is valid.
1639         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
1640         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

1675
1676 2000-11-07  Akim Demaille  <akim@epita.fr>
1677
1678         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
1679         Merge in a single CPP if/else.

1720         * src/main.c (main): Don't use `atexit' to register `done', since
1721         it no longer has to remove tmp files, just call `output_files'
1722         when there are no errors.
1723

1827         When a literal string is used to define two different tokens,
1828         `bison -v' segfaults.
1829         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
1830
1831         * tests/regression.m4: New file.
1832         Include the core of the sample provided by Piotr Gackiewicz.
1833         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
1834         properly.
1835

1837
1838         * src/reader.c (parse_expect_decl): Keep `count' within the size
1839         of `buffer'.

1842 2000-10-02  Paul Eggert  <eggert@twinsun.com>
1843
1844         * bison.s1 (yyparse): Assign the default value
1845         unconditionally, to avoid a GCC warning and make the parser a
1846         tad smaller.
1847
1848 2000-10-02  Akim Demaille  <akim@epita.fr>
1849
1850         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
1851         options.
1852
1853 2000-10-02  Akim Demaille  <akim@epita.fr>
1854
1855         * src/derives.c, src/print.c, src/reduce.c: To ease the
1856         translation, move some `\n' out of the translated strings.
1857
1858 2000-10-02  Akim Demaille  <akim@epita.fr>
1859
1860         The location tracking mechanism is precious for parse error
1861         messages.  Nevertheless, it is enabled only when `@n' is used in
1862         the grammar, which is a different issue (you can use it in error
1863         message, but not in the grammar per se).  Therefore, there should
1864         be another means to enable it.
1865
1866         * src/getargs.c (getargs): Support `--locations'.
1867         (usage): Report it.
1868         * src/getargs.h (locationsflag): Export it.
1869         * src/lex.c (percent_table): Support `%locations'.
1870         * src/reader.c (yylsp_needed): Remove this variable, now replaced
1871         with `locationsflag'.
1872         * doc/bison.texinfo: Document `--locations' and `%locations'.
1873         Sort the options.
1874         * tests/calc.m4: Test it.
1875
1876         For regularity of the names, replace each
1877         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
1878         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
1879         In addition replace each `flag' with `_flag'.
1880
1881 2000-10-02  Akim Demaille  <akim@epita.fr>
1882
1883         Also test parse error messages, including with YYERROR_VERBOSE.
1884
1885         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
1886         associative).
1887         Use it to check the computations.
1888         Use it to check `nonassoc' is honored.
1889         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
1890         `--yyerror-verbose'.
1891         (_AT_CHECK_CALC): Adjust to this option.
1892         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
1893
1894 2000-10-02  Akim Demaille  <akim@epita.fr>
1895
1896         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
1897         the latter demonstrates a flaw in the handling of non debugging
1898         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
1899         was used in order to simplify:
1900
1901         #if YYDEBUG
1902         if (yydebug)
1903         {
1904         ...
1905         }
1906         #endif
1907
1908         into
1909
1910         if (yydebug)
1911         {
1912         ...
1913         }
1914
1915         unfortunately this leads to a CPP conflict when
1916         `--name-prefix=foo' is used since it produces `#define yydebug
1917         foodebug'.
1918
1919         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
1920         (YYDPRINTF): New macro.
1921         Spread its use.
1922         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
1923         the bison options.
1924         Also test `--verbose', `--defines' and `--name-prefix'.
1925
1926 2000-10-02  Akim Demaille  <akim@epita.fr>
1927
1928         Improve the readability of the produced parsers.
1929
1930         * src/bison.s1: Formatting changes.
1931         Improve the comment related to the `$' mark.
1932         (yydefault): Don't fall through to `yyresume': `goto' there.
1933         * src/output.c (output_parser): When the `$' is met, skip the end
1934         of its line.
1935         New variable, `number_of_dollar_signs', to check there's exactly
1936         one `$' in the parser skeleton.
1937
1938 2000-10-02  Akim Demaille  <akim@epita.fr>
1939
1940         * lib/xstrdup.c: New file, from the fileutils.
1941         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
1942         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
1943         instead of strlen + xmalloc + strcpy.
1944         * src/symtab.c (copys): Remove, use xstrdup instead.
1945
1946 2000-10-02  Akim Demaille  <akim@epita.fr>
1947
1948         * src/gram.h (associativity): New enum type which replaces the
1949         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
1950         `right_assoc', `left_assoc' and `non_assoc'.
1951         Adjust all dependencies.
1952         * src/reader.c: Formatting changes.
1953         (LTYPESTR): Don't define it, use it as a literal in
1954         `reader_output_yylsp'.
1955         * src/symtab.h (symbol_class): New enum type which replaces the
1956         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
1957         `sunknown', `stoken and `snterm'.
1958
1959 2000-10-02  Akim Demaille  <akim@epita.fr>
1960
1961         * src/getargs.c (fixed_outfiles): Rename as...
1962         (yaccflag): for consistency and accuracy.
1963         Adjust dependencies.
1964
1965 2000-10-02  Akim Demaille  <akim@epita.fr>
1966
1967         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
1968         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
1969         difficult and introduced a lot of core dump.  It turns out that
1970         Bison used an implementation of `xmalloc' based on `calloc', and
1971         at various places it does depend upon the initialization to 0.  I
1972         have not tried to isolate the pertinent places, and all the former
1973         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
1974         someone should address this issue.
1975
1976         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
1977         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

1988
1989 2000-10-02  Akim Demaille  <akim@epita.fr>
1990
1991         * src/state.h (nstates, final_state, first_state, first_shift)

2069 2000-10-02  Akim Demaille  <akim@epita.fr>
2070
2071         * src/output.c (token_actions): Introduce a temporary array,

2073         output_short_table.
2074
2075 2000-10-02  Akim Demaille  <akim@epita.fr>
2076
2077         `user_toknums' is output as a `short[]' in `output.c', while it is
2078         defined as a `int[]' in `reader.c'.  For consistency with the
2079         other output tables, `user_toknums' is now defined as a table of
2080         shorts.
2081
2082         * src/reader.c (user_toknums): Be a short table instead of an int

2095         order to get rid of the `static' prototypes.
2096         No longer use `register'.
2097         * src/output.h: New file.
2098         Propagate its inclusion in files explicitly prototyping functions
2099         from output.c.

2121         inclusion.
2122         Don't define PARAMS.
2123         * src/system.h: Define PARAMS.
2124         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
2125         purpose of config.h.  system.h must not try to fix wrong
2126         definitions in config.h.

2166
2167         * configure.in: Append WARNING_CFLAGS to CFLAGS.

2288         the file name, not the whole `#line LINE FILE'.
2289
2290 2000-03-17  Akim Demaille  <akim@epita.fr>
2291
2292         On syntax errors, report the token on which we choked.
2293
2294         * src/bison.s1 (yyparse): In the label yyerrlab, when

2314         copy_comment.  Removed now unused `match', `ended',
2315         `cplus_comment'.
2316         (copy_comment, copy_string): Moved, to be visible from
2317         copy_definition.

2320
2321         * src/reader.c (copy_string): Declare `static inline'.  No

2343
2344         Change the handling of @s so that they behave exactly like $s.
2345         There is now a pseudo variable @$ (readble and writable), location
2346         of the lhs of the rule (by default ranging from the location of
2347         the first symbol of the rhs, to the location of the last symbol,
2348         or, if the rhs is empty, YYLLOC).
2349
2350         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2351         yyval.
2352         (yyparse): When providing a default semantic action, provide a
2353         default location action.
2354         (after the $): No longer change `*YYLSP', just stack YYLOC the
2355         same way you stack YYVAL.
2356         * src/reader.c (read_declarations): Use warns.
2357         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2358         (copy_action, case '@'): Likewise.
2359         Use a standard error message, to save useless work from
2360         translators.
2361
2362 2000-03-17  Akim Demaille  <akim@epita.fr>
2363

2381
2382         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
2383         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2384         One `#if YYDEBUG' remains, since it uses variables which are
2385         defined only if `YYDEBUG != 0'.
2386
2387 2000-03-16  Akim Demaille  <akim@epita.fr>
2388
2389         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

2413         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

2419         the proper line number and file name.
2420         (DEFS): Propagate the location of bison library files and of the
2421         locale files.
2422         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
2423         builddir.
2424         * acinclude.m4: Remove, replaced by the directory m4.
2425         * m4/Makefile.am (EXTRA_DIST): New variable.
2426         * m4/gettext.m4: New file, from the fileutils.

3113         major changes to files.c.
