ChangeLog

   1 2001-12-04  Paul Eggert  <eggert@twinsun.com>
   2
   3         * src/bison.simple (YYPOINTER): New macro.
   4         (YYSTACK_RELOCATE): Use it to avoid a GCC warning.
   5         (yystpcpy): Use prototype if __STDC__ is defined, not just
   6         if __cplusplus is defined.
   7
   8 2001-11-30  Akim Demaille  <akim@epita.fr>
   9
  10         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
  11         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
  12         Gettext doesn't compile cleanly, and dies with -Werror.
  13         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
  14         Include WARNING_CFLAGS here.
  15         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
  16         before being defined.
  17
  18 2001-11-30  Paul Eggert  <eggert@twinsun.com>
  19
  20         * lib/quotearg.h (quotearg_n, quotearg_n_style):
  21         First arg is int, not unsigned.
  22         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
  23         (SIZE_MAX, UINT_MAX): New macros.
  24         (quotearg_n_options): Abort if N is negative.
  25         Avoid overflow check on hosts where size_t is 64 bits and int
  26         is 32 bits, as overflow is impossible there.
  27         Fix off-by-one typo that caused unnecessary reallocation.
  28
  29 2001-11-30  Paul Eggert  <eggert@twinsun.com>
  30
  31         Name space cleanup in generated parser.
  32
  33         * doc/bison.texinfo (Bison Parser): Discuss system headers
  34         and their effect on the user name space.
  35
  36         * src/bison.simple:
  37         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
  38         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
  39         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
  40
  41         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
  42         on user names when possible.
  43
  44         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
  45         Simplify test for whather <alloca.h> exists.
  46
  47         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
  48
  49         (<stdio.h>): Include if YYDEBUG.
  50
  51         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
  52         ! defined (yyoverflow) && ! defined (yymemcpy).
  53
  54         (yymemcpy, yyparse): Rename local variables as needed so that
  55         they all begin with 'yy'.
  56
  57         (yystrlen, yystpcpy): New functions.
  58
  59         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
  60         All uses changed.
  61
  62         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
  63         instead of relying on string.h functions.  Use YYSTACK_ALLOC
  64         and YYSTACK_FREE instead of malloc and free.
  65
  66 2001-11-30  Akim Demaille  <akim@epita.fr>
  67
  68         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
  69         if body instead of `;' to pacify GCC's warnings.
  70
  71 2001-11-30  Akim Demaille  <akim@epita.fr>
  72
  73         Instead of mapping the LHS of unused rules to -1, keep the LHS
  74         valid, but flag the rules as invalid.
  75
  76         * src/gram.h (rule_t): `useful' is a new member.
  77         * src/print.c (print_grammar): Adjust.
  78         * src/derives.c (set_derives): Likewise.
  79         * src/reader.c (packgram, reduce_output): Likewise.
  80         * src/reduce.c (reduce_grammar_tables): Likewise.

  84
  85         * src/reduce.c (reduce_output): Formatting changes.
  86         * src/print.c (print_results, print_grammar): Likewise.

  88         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
  89
  90 2001-11-30  Akim Demaille  <akim@epita.fr>
  91
  92         * src/reduce.c (nonterminals_reduce): Instead of throwing away
  93         useless nonterminals, move them at the end of the symbol arrays.
  94         (reduce_output): Adjust.
  95         * tests/reduce.at (Useless Nonterminals): Adjust.
  96
  97 2001-11-30  Akim Demaille  <akim@epita.fr>
  98
  99         * src/reduce.c: Various comment/formatting changes.
 100         (nonterminals_reduce): New, extracted from...
 101         (reduce_grammar_tables): here.
 102         (reduce_grammar): Call nonterminals_reduce.
 103
 104 2001-11-29  Paul Eggert  <eggert@twinsun.com>
 105
 106         * src/bison.simple (YYSTACK_REALLOC): Remove.
 107         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
 108         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
 109         New macros.
 110         (union yyalloc): New type.
 111         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
 112         an arbitrary restriction on hosts where size_t is wider than int.
 113
 114         (yyparse): Don't dump core if alloca or malloc fails; instead, report
 115         a parser stack overflow.  Allocate just one block of memory for all
 116         three stacks, instead of allocating three blocks; this typically is
 117         faster and reduces fragmentation.
 118
 119         Do not limit the number of items in the stack to a value that fits
 120         in 'int', as this is an arbitrary limit on hosts with 64-bit
 121         size_t and 32-bit int.
 122
 123 2001-11-28  Akim Demaille  <akim@epita.fr>

 127
 128 2001-11-28  Akim Demaille  <akim@epita.fr>
 129
 130         * src/closure.c (closure): `b' and `ruleno' denote the same value:
 131         keep ruleno only.
 132
 133 2001-11-28  Akim Demaille  <akim@epita.fr>
 134
 135         * src/closure.c (closure): Instead of looping over word in array
 136         then bits in words, loop over bits in array.
 137
 138 2001-11-28  Akim Demaille  <akim@epita.fr>
 139
 140         * src/closure.c (closure): No longer optimize the special case
 141         where all the bits of `ruleset[r]' are set to 0, to make the code
 142         clearer.
 143
 144 2001-11-28  Akim Demaille  <akim@epita.fr>
 145
 146         * src/closure.c (closure): `r' and `c' are new variables, used to
 147         de-obfuscate accesses to RULESET and CORE.
 148
 149 2001-11-28  Akim Demaille  <akim@epita.fr>

 157
 158 2001-11-28  Akim Demaille  <akim@epita.fr>
 159
 160         * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
 161         * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
 162         as all tags are free'ed afterwards.
 163         From Enrico Scholz.
 164
 165 2001-11-27  Akim Demaille  <akim@epita.fr>

 176
 177         * tests/torture.at (Exploding the Stack Size with Malloc):
 178         s/YYSTACK_USE_ALLOCA_ALLOCA/YYSTACK_USE_ALLOCA/.

 220
 221         * src/conflicts.c (conflicts_print): Don't complain at all when

 246
 247 2001-11-23  Akim Demaille  <akim@epita.fr>
 248
 249         Attaching lineno to buckets is stupid, since only one copy of each
 250         symbol is kept, only the line of the first occurrence is kept too.

 326
 327 2001-11-19  Akim Demaille  <akim@epita.fr>
 328
 329         * src/LR0.c (new_itemsets, get_state): Use more arrays and fewer
 330         pointers to clarify the code.
 331         (save_reductions, save_shifts): Factor common parts of alternatives.
 332
 333 2001-11-19  Akim Demaille  <akim@epita.fr>

 340         * src/derives.c: Likewise.
 341         * src/reduce.c: (inaccessable_symbols): Using if is better style

 344
 345 2001-11-19  Akim Demaille  <akim@epita.fr>

 369 2001-11-19  Akim Demaille  <akim@epita.fr>
 370
 371         * src/vcg.c: You do the output, so you are responsible of the
 372         handling of VCG syntax, in particular: use quotearg.
 373         * src/print_graph.c: Don't.
 374         (print_actions): Don't output the actions as part of the nodes,
 375         since that's the job of the edges.
 376         (print_state): Don't output by hand: fill the node description,
 377         and ask for its output.
 378
 379 2001-11-19  Akim Demaille  <akim@epita.fr>

 502         Revert a previous patch:  these are really const.
 503         * src/conflicts.c (conflict_report): Additional useless pair of

 505         * src/lex.c (parse_percent_token): Replace equal_offset with

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

 617         with yyltype/YYLTYPE.  This allows inclusion of the generated

 622
 623         * src/getargs.c (longopts): Support `--output'.  getopt is now
 624         able to understand that `--out' is OK: the two racing long options
 625         are aliases.

 638         Add description of `%name-prefix', `file-prefix', and `output'.
 639         Promote `-' over `_' in directive names.
 640         (Bison Options): s/%locactions/%locations/.  Nice Freudian slip.
 641         Simplify the description of `--name-prefix'.
 642         Promote `-' over `_' in directive names.
 643         Promote `--output' over `--output-file'.

1493 2001-02-21  Akim Demaille  <akim@epita.fr>
1494
1495         * src/reader.c (gensym): `gensym_count' is your own.
1496         Use a static buf to create the symbol name, as token_buffer is no
1497         longer a buffer.
1498
1499 2001-02-08  Akim Demaille  <akim@epita.fr>
1500
1501         * src/conflicts.c (conflict_report): Be sure not to append to res
1502         between two calls, which could happen if both first sprintf were
1503         skipped, but not the first cp += strlen.
1504
1505 2001-02-08  Akim Demaille  <akim@epita.fr>
1506
1507         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
1508         New, from fileutils 4.0.37.
1509         * configure.in: Require Autoconf 2.49c.  I took some time before
1510         making this decision.  This is the only way out for portability
1511         issues in Bison, it would mean way too much duplicate effort to
1512         import in Bison features implemented in 2.49c since 2.13.
1513         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
1514
1515 2001-02-02  Akim Demaille  <akim@epita.fr>
1516
1517         * lib/malloc.c, lib/realloc.c: New, from the fileutils 4.0.37.

1519
1520 2001-01-19  Akim Demaille  <akim@epita.fr>
1521
1522         Get rid of the ad hoc handling of token_buffer in the scanner: use
1523         the obstacks.
1524
1525         * src/lex.c (token_obstack): New.
1526         (init_lex): Initialize it.  No longer call...
1527         (grow_token_buffer): this.  Remove it.
1528         Adjust all the places which used it to use the obstack.
1529
1530 2001-01-19  Akim Demaille  <akim@epita.fr>
1531
1532         * src/lex.h: Rename all the tokens:
1533         s/\bENDFILE\b/tok_eof/g;
1534         s/\bIDENTIFIER\b/tok_identifier/g;
1535         etc.
1536         Let them be enums, not #define, to ease debugging.
1537         Adjust all the code.
1538
1539 2001-01-18  Akim Demaille  <akim@epita.fr>
1540
1541         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
1542         * src/lex.c (maxtoken, grow_token_buffer): Static.
1543
1544 2001-01-18  Akim Demaille  <akim@epita.fr>
1545
1546         Since we now use obstacks, more % directives can be enabled.
1547
1548         * src/lex.c (percent_table): Also accept `%yacc',
1549         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
1550         `%debug'.
1551         Handle the actions for `%semantic_parser' and `%pure_parser' here,
1552         instead of returning a token.
1553         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
1554         * src/reader.c (read_declarations): Adjust.
1555         * src/files.c (open_files): Don't call `compute_base_names', don't
1556         compute `attrsfile' since they depend upon data which might be
1557         *in* the input file now.
1558         (output_files): Do it here.
1559         * src/output.c (output_headers): Document the fact that this patch
1560         introduces a guaranteed SEGV for semantic parsers.
1561         * doc/bison.texinfo: Document them.
1562         * tests/suite.at: Exercise these %options.
1563
1564 2000-12-20  Akim Demaille  <akim@epita.fr>
1565
1566         Also handle the output file (--verbose) with obstacks.
1567
1568         * files.c (foutput): Remove.
1569         (output_obstack): New.
1570         Adjust all dependencies.
1571         * src/conflicts.c: Return a string.
1572         * src/system.h (obstack_grow_string): Rename as...
1573         (obstack_sgrow): this.  Be ready to work with non literals.

1577
1578         * src/files.c (open_files): Fix the computation of short_base_name
1579         in the case of `-o foo.tab.c'.
1580
1581 2000-12-20  Akim Demaille  <akim@epita.fr>
1582
1583         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
1584         (copy_dollar): Now that everything uses obstacks, get rid of the
1585         FILE * parameters.
1586
1587 2000-12-20  Akim Demaille  <akim@epita.fr>
1588
1589         * src/files.c (open_files): Actually the `.output' file is based
1590         on the short_base_name, not base_name.
1591         * tests/suite.at (Checking output file names): Adjust.
1592
1593 2000-12-20  Akim Demaille  <akim@epita.fr>
1594
1595         * src/bison.s1: Remove, we now use directly...
1596         * src/bison.simple: this.
1597         * src/Makefile.am: Use pkgdata instead of data.
1598
1599 2000-12-20  Akim Demaille  <akim@epita.fr>

1611         (open_files): Don't compute them.
1612         (output_files): Adjust.
1613         (base_name, short_base_name): Be global.
1614         Adjust dependencies.
1615
1616 2000-12-19  Akim Demaille  <akim@epita.fr>
1617
1618         * src/files.c (strsuffix): New.
1619         (stringappend): Be just like strcat but allocate.
1620         (base_names): Eve out from open_files.
1621         Try to simplify the rather hairy computation of base_name and
1622         short_base_name.
1623         (open_files): Use it.
1624         * tests/suite.at (Checking output file names): New test.
1625
1626 2000-12-19  Akim Demaille  <akim@epita.fr>

1631         `$'.
1632         * src/bison.s1: s/$/%% actions/.
1633         * src/bison.hairy: Likewise.
1634
1635 2000-12-19  Akim Demaille  <akim@epita.fr>
1636
1637         * src/output.c (output_parser): Compute the `#line' lines when
1638         there are.
1639         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
1640         Suggested by Hans Aberg.
1641
1642 2000-12-19  Akim Demaille  <akim@epita.fr>
1643
1644         Let the handling of the skeleton files be local to the procedures
1645         that use it.
1646
1647         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
1648         longer static.
1649         (fparser, open_extra_files): Remove.

1658

1661
1662 2000-12-19  Akim Demaille  <akim@epita.fr>
1663
1664         * src/files.c (open_files): Yipee!  We no longer need all the code
1665         looking for `/tmp' since we have no tmp file.
1666
1667 2000-12-19  Akim Demaille  <akim@epita.fr>
1668
1669         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
1670         New macros.
1671         * src/files.c (open_files): Less dependency on MSDOS etc.

1695
1696         * lib/obstack.h: Formatting changes.
1697         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
1698         prevents type checking.
1699         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
1700         cast the value to (void *): assigning a `foo *' to a `void *'
1701         variable is valid.
1702         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
1703         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

1738
1739 2000-11-07  Akim Demaille  <akim@epita.fr>
1740
1741         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
1742         Merge in a single CPP if/else.
1743
1744 2000-11-07  Akim Demaille  <akim@epita.fr>
1745

1747         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
1748         argument `data' for consistency with the prototypes.

1751         `address' for consistency.  Qualify it `const'.

1753         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify

1762
1763 2000-11-03  Akim Demaille  <akim@epita.fr>
1764
1765         For some reason, this was not applied.
1766
1767         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

1782         Use `obstack_save'.
1783         * src/main.c (main): Don't use `atexit' to register `done', since
1784         it no longer has to remove tmp files, just call `output_files'
1785         when there are no errors.
1786
1787 2000-11-02  Akim Demaille  <akim@epita.fr>

1856         * src/reader.c (copy_comment2): Expect the input stream to be on
1857         the `/' which is suspected to open a comment, instead of being
1858         called after `//' or `/*' was read.
1859         (copy_comment, copy_definition, parse_union_decl, copy_action)
1860         (copy_guard): Adjust.

1887
1888 2000-10-04  Akim Demaille  <akim@epita.fr>

1890         When a literal string is used to define two different tokens,
1891         `bison -v' segfaults.
1892         Reported by Piotr Gackiewicz, and fixed by Neil Booth.

1897         properly.
1898
1899 2000-10-04  Akim Demaille  <akim@epita.fr>
1900
1901         * src/reader.c (parse_expect_decl): Keep `count' within the size
1902         of `buffer'.
1903         From Neil Booth.
1904
1905 2000-10-02  Paul Eggert  <eggert@twinsun.com>
1906
1907         * bison.s1 (yyparse): Assign the default value
1908         unconditionally, to avoid a GCC warning and make the parser a
1909         tad smaller.
1910
1911 2000-10-02  Akim Demaille  <akim@epita.fr>
1912
1913         * src/getargs.c (getargs): Don't dump `--help' on unrecognized

1917
1918         * src/derives.c, src/print.c, src/reduce.c: To ease the

1920
1921 2000-10-02  Akim Demaille  <akim@epita.fr>
1922
1923         The location tracking mechanism is precious for parse error
1924         messages.  Nevertheless, it is enabled only when `@n' is used in
1925         the grammar, which is a different issue (you can use it in error
1926         message, but not in the grammar per se).  Therefore, there should
1927         be another means to enable it.
1928
1929         * src/getargs.c (getargs): Support `--locations'.
1930         (usage): Report it.
1931         * src/getargs.h (locationsflag): Export it.
1932         * src/lex.c (percent_table): Support `%locations'.
1933         * src/reader.c (yylsp_needed): Remove this variable, now replaced
1934         with `locationsflag'.
1935         * doc/bison.texinfo: Document `--locations' and `%locations'.
1936         Sort the options.
1937         * tests/calc.m4: Test it.
1938
1939         For regularity of the names, replace each
1940         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
1941         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
1942         In addition replace each `flag' with `_flag'.
1943
1944 2000-10-02  Akim Demaille  <akim@epita.fr>
1945
1946         Also test parse error messages, including with YYERROR_VERBOSE.
1947
1948         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
1949         associative).
1950         Use it to check the computations.
1951         Use it to check `nonassoc' is honored.
1952         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
1953         `--yyerror-verbose'.
1954         (_AT_CHECK_CALC): Adjust to this option.
1955         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
1956
1957 2000-10-02  Akim Demaille  <akim@epita.fr>
1958
1959         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
1960         the latter demonstrates a flaw in the handling of non debugging
1961         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
1962         was used in order to simplify:
1963
1964         #if YYDEBUG
1965         if (yydebug)
1966         {
1967         ...
1968         }
1969         #endif
1970
1971         into
1972
1973         if (yydebug)
1974         {
1975         ...
1976         }
1977
1978         unfortunately this leads to a CPP conflict when
1979         `--name-prefix=foo' is used since it produces `#define yydebug
1980         foodebug'.
1981
1982         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
1983         (YYDPRINTF): New macro.
1984         Spread its use.
1985         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
1986         the bison options.
1987         Also test `--verbose', `--defines' and `--name-prefix'.
1988
1989 2000-10-02  Akim Demaille  <akim@epita.fr>
1990
1991         Improve the readability of the produced parsers.
1992
1993         * src/bison.s1: Formatting changes.
1994         Improve the comment related to the `$' mark.
1995         (yydefault): Don't fall through to `yyresume': `goto' there.
1996         * src/output.c (output_parser): When the `$' is met, skip the end
1997         of its line.
1998         New variable, `number_of_dollar_signs', to check there's exactly
1999         one `$' in the parser skeleton.
2000
2001 2000-10-02  Akim Demaille  <akim@epita.fr>
2002
2003         * lib/xstrdup.c: New file, from the fileutils.
2004         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
2005         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
2006         instead of strlen + xmalloc + strcpy.
2007         * src/symtab.c (copys): Remove, use xstrdup instead.
2008
2009 2000-10-02  Akim Demaille  <akim@epita.fr>
2010
2011         * src/gram.h (associativity): New enum type which replaces the
2012         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
2013         `right_assoc', `left_assoc' and `non_assoc'.
2014         Adjust all dependencies.
2015         * src/reader.c: Formatting changes.
2016         (LTYPESTR): Don't define it, use it as a literal in
2017         `reader_output_yylsp'.
2018         * src/symtab.h (symbol_class): New enum type which replaces the
2019         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
2020         `sunknown', `stoken and `snterm'.
2021
2022 2000-10-02  Akim Demaille  <akim@epita.fr>
2023
2024         * src/getargs.c (fixed_outfiles): Rename as...

2026         Adjust dependencies.
2027
2028 2000-10-02  Akim Demaille  <akim@epita.fr>
2029
2030         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
2031         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
2032         difficult and introduced a lot of core dump.  It turns out that
2033         Bison used an implementation of `xmalloc' based on `calloc', and
2034         at various places it does depend upon the initialization to 0.  I
2035         have not tried to isolate the pertinent places, and all the former
2036         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
2037         someone should address this issue.
2038
2039         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
2040         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

2046 2000-10-02  Akim Demaille  <akim@epita.fr>
2047
2048         Various anti-`extern in *.c' changes.

2051
2052 2000-10-02  Akim Demaille  <akim@epita.fr>
2053
2054         * src/state.h (nstates, final_state, first_state, first_shift)

2058         * src/getargs.c (statisticsflag): New variable.

2132 2000-10-02  Akim Demaille  <akim@epita.fr>
2133
2134         * src/output.c (token_actions): Introduce a temporary array,
2135         YYDEFACT, that makes it possible for this function to use
2136         output_short_table.
2137
2138 2000-10-02  Akim Demaille  <akim@epita.fr>
2139
2140         `user_toknums' is output as a `short[]' in `output.c', while it is
2141         defined as a `int[]' in `reader.c'.  For consistency with the
2142         other output tables, `user_toknums' is now defined as a table of
2143         shorts.
2144
2145         * src/reader.c (user_toknums): Be a short table instead of an int
2146         table.

2156
2157         * src/output.c (output): Topological sort of the functions, in
2158         order to get rid of the `static' prototypes.
2159         No longer use `register'.
2160         * src/output.h: New file.
2161         Propagate its inclusion in files explicitly prototyping functions
2162         from output.c.

2173         (initialize_closure, finalize_closure):  Rename as...
2174         (new_closure, free_closure): these.  Adjust dependencies.

2184         inclusion.
2185         Don't define PARAMS.
2186         * src/system.h: Define PARAMS.
2187         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
2188         purpose of config.h.  system.h must not try to fix wrong
2189         definitions in config.h.

2326         * configure.in: Adjust.
2327         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's

2351         the file name, not the whole `#line LINE FILE'.
2352
2353 2000-03-17  Akim Demaille  <akim@epita.fr>
2354
2355         On syntax errors, report the token on which we choked.
2356
2357         * src/bison.s1 (yyparse): In the label yyerrlab, when

2375
2376         * src/reader.c (copy_definition): Use copy_string and
2377         copy_comment.  Removed now unused `match', `ended',
2378         `cplus_comment'.
2379         (copy_comment, copy_string): Moved, to be visible from
2380         copy_definition.
2381

2383
2384         * src/reader.c (copy_string): Declare `static inline'.  No

2406
2407         Change the handling of @s so that they behave exactly like $s.
2408         There is now a pseudo variable @$ (readble and writable), location
2409         of the lhs of the rule (by default ranging from the location of
2410         the first symbol of the rhs, to the location of the last symbol,
2411         or, if the rhs is empty, YYLLOC).
2412
2413         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2414         yyval.
2415         (yyparse): When providing a default semantic action, provide a
2416         default location action.
2417         (after the $): No longer change `*YYLSP', just stack YYLOC the
2418         same way you stack YYVAL.
2419         * src/reader.c (read_declarations): Use warns.
2420         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2421         (copy_action, case '@'): Likewise.
2422         Use a standard error message, to save useless work from
2423         translators.
2424
2425 2000-03-17  Akim Demaille  <akim@epita.fr>
2426

2444
2445         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
2446         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2447         One `#if YYDEBUG' remains, since it uses variables which are
2448         defined only if `YYDEBUG != 0'.
2449
2450 2000-03-16  Akim Demaille  <akim@epita.fr>
2451
2452         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

2474         handled via src/Makefile.am.

2476         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

2482         the proper line number and file name.
2483         (DEFS): Propagate the location of bison library files and of the
2484         locale files.
2485         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
2486         builddir.
2487         * acinclude.m4: Remove, replaced by the directory m4.
2488         * m4/Makefile.am (EXTRA_DIST): New variable.
2489         * m4/gettext.m4: New file, from the fileutils.

3176         major changes to files.c.
