   1 2001-11-30  Akim Demaille  <akim@epita.fr>
   2
   3         * src/reduce.c (reduce_output): Formatting changes.
   4         * src/print.c (print_results, print_grammar): Likewise.
   5         * tests/regression.at (Rule Line Numbers)
   6         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
   7
   8 2001-11-30  Akim Demaille  <akim@epita.fr>
   9
  10         * src/reduce.c (nonterminals_reduce): Instead of throwing away
  11         useless nonterminals, move them at the end of the symbol arrays.
  12         (reduce_output): Adjust.
  13         * tests/reduce.at (Useless Nonterminals): Adjust.
  14
  15 2001-11-30  Akim Demaille  <akim@epita.fr>
  16
  17         * src/reduce.c: Various comment/formatting changes.
  18         (nonterminals_reduce): New, extracted from...
  19         (reduce_grammar_tables): here.
  20         (reduce_grammar): Call nonterminals_reduce.
  21
  22 2001-11-29  Paul Eggert  <eggert@twinsun.com>
  23
  24         * src/bison.simple (YYSTACK_REALLOC): Remove.
  25         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
  26         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
  27         New macros.
  28         (union yyalloc): New type.
  29         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
  30         an arbitrary restriction on hosts where size_t is wider than int.
  31
  32         (yyparse): Don't dump core if alloca or malloc fails; instead, report
  33         a parser stack overflow.  Allocate just one block of memory for all
  34         three stacks, instead of allocating three blocks; this typically is
  35         faster and reduces fragmentation.
  36
  37         Do not limit the number of items in the stack to a value that fits
  38         in 'int', as this is an arbitrary limit on hosts with 64-bit
  39         size_t and 32-bit int.
  40
  41 2001-11-28  Akim Demaille  <akim@epita.fr>

  45
  46 2001-11-28  Akim Demaille  <akim@epita.fr>
  47
  48         * src/closure.c (closure): `b' and `ruleno' denote the same value:
  49         keep ruleno only.
  50
  51 2001-11-28  Akim Demaille  <akim@epita.fr>
  52
  53         * src/closure.c (closure): Instead of looping over word in array
  54         then bits in words, loop over bits in array.
  55
  56 2001-11-28  Akim Demaille  <akim@epita.fr>
  57
  58         * src/closure.c (closure): No longer optimize the special case
  59         where all the bits of `ruleset[r]' are set to 0, to make the code
  60         clearer.
  61
  62 2001-11-28  Akim Demaille  <akim@epita.fr>
  63
  64         * src/closure.c (closure): `r' and `c' are new variables, used to

  77
  78         * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
  79         * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
  80         as all tags are free'ed afterwards.

 138
 139         * src/conflicts.c (conflicts_print): Don't complain at all when

 164
 165 2001-11-23  Akim Demaille  <akim@epita.fr>
 166
 167         Attaching lineno to buckets is stupid, since only one copy of each
 168         symbol is kept, only the line of the first occurrence is kept too.

 290         handling of VCG syntax, in particular: use quotearg.
 291         * src/print_graph.c: Don't.
 292         (print_actions): Don't output the actions as part of the nodes,
 293         since that's the job of the edges.
 294         (print_state): Don't output by hand: fill the node description,
 295         and ask for its output.
 296

 391         * tests/calc.at, tests/output.at, tests/regression.at,
 392         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
 393         now the tests are run in private dirs, therefore AC_CLEANUP and
 394         family can be simplified to 0-ary.
 395         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
 396         use abs. path to find config.h.
 397
 398 2001-11-14  Akim Demaille  <akim@epita.fr>
 399
 400         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
 401         stderr, there can be way too much random noise.
 402         Instead pass -Werror to GCC and rely on the exit status.
 403         Reported by Wolfram Wagner.

 405 2001-11-14  Akim Demaille  <akim@epita.fr>
 406
 407         * src/bison.simple (yyparse): Let yyls1, yyss1 and yyvs1 be

 418
 419         * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
 420         Revert a previous patch:  these are really const.
 421         * src/conflicts.c (conflict_report): Additional useless pair of
 422         braces to pacify GCC's warnings for `if () if () {} else {}'.
 423         * src/lex.c (parse_percent_token): Replace equal_offset with
 424         arg_offset.
 425         arg is const.
 426         Be sure to strdup `arg' when used, since there is no reason for
 427         token_buffer not to change.

 439
 440         * src/system.h (ngettext): Now that we use ngettext, be sure to
 441         provide a default definition when NLS are not used that takes care
 442         of the cardinality.
 443
 444 2001-11-12  Akim Demaille  <akim@epita.fr>
 445

 534         * src/reader.c (parse_union_decl): Output yystype/YYSTYPE as we do
 535         with yyltype/YYLTYPE.  This allows inclusion of the generated
 536         header within the parser if the compiler, such as GGC, accepts
 537         multiple equivalent #defines.
 538
 539 2001-11-04  Akim Demaille  <akim@epita.fr>
 540
 541         * src/getargs.c (longopts): Support `--output'.  getopt is now
 542         able to understand that `--out' is OK: the two racing long options
 543         are aliases.
 544         (usage): Adjust.
 545         * src/lex.h (tok_setopt): Remove, replaced with...

 552         Promote `-' over `_' in directive names.
 553         * doc/bison.texinfo (Decl Summary): Split the list into
 554         `directives for grammars' and `directives for bison'.
 555         Sort'em.
 556         Add description of `%name-prefix', `file-prefix', and `output'.
 557         Promote `-' over `_' in directive names.
 558         (Bison Options): s/%locactions/%locations/.  Nice Freudian slip.
 559         Simplify the description of `--name-prefix'.
 560         Promote `-' over `_' in directive names.
 561         Promote `--output' over `--output-file'.
 562         Fix the description of `--defines'.

 575         * src/lex.c (lex): Adjust.
 576

1429         issues in Bison, it would mean way too much duplicate effort to
1430         import in Bison features implemented in 2.49c since 2.13.

1464         Since we now use obstacks, more % directives can be enabled.
1465
1466         * src/lex.c (percent_table): Also accept `%yacc',
1467         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
1468         `%debug'.
1469         Handle the actions for `%semantic_parser' and `%pure_parser' here,
1470         instead of returning a token.
1471         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
1472         * src/reader.c (read_declarations): Adjust.
1473         * src/files.c (open_files): Don't call `compute_base_names', don't

1475         *in* the input file now.
1476         (output_files): Do it here.
1477         * src/output.c (output_headers): Document the fact that this patch

1506
1507         * src/files.c (open_files): Actually the `.output' file is based

1542         * tests/suite.at (Checking output file names): New test.

1615         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
1616         prevents type checking.
1617         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
1618         cast the value to (void *): assigning a `foo *' to a `void *'
1619         variable is valid.
1620         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

1658

1701         * src/main.c (main): Don't use `atexit' to register `done', since
1702         it no longer has to remove tmp files, just call `output_files'
1703         when there are no errors.
1704
1705 2000-11-02  Akim Demaille  <akim@epita.fr>

1809         `bison -v' segfaults.
1810         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
1811
1812         * tests/regression.m4: New file.

1823 2000-10-02  Paul Eggert  <eggert@twinsun.com>
1824
1825         * bison.s1 (yyparse): Assign the default value
1826         unconditionally, to avoid a GCC warning and make the parser a
1827         tad smaller.

1829 2000-10-02  Akim Demaille  <akim@epita.fr>
1830

1840
1841         The location tracking mechanism is precious for parse error
1842         messages.  Nevertheless, it is enabled only when `@n' is used in
1843         the grammar, which is a different issue (you can use it in error
1844         message, but not in the grammar per se).  Therefore, there should
1845         be another means to enable it.
1846
1847         * src/getargs.c (getargs): Support `--locations'.
1848         (usage): Report it.

1851         * src/reader.c (yylsp_needed): Remove this variable, now replaced
1852         with `locationsflag'.
1853         * doc/bison.texinfo: Document `--locations' and `%locations'.
1854         Sort the options.
1855         * tests/calc.m4: Test it.
1856
1857         For regularity of the names, replace each
1858         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
1859         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
1860         In addition replace each `flag' with `_flag'.
1861
1862 2000-10-02  Akim Demaille  <akim@epita.fr>
1863
1864         Also test parse error messages, including with YYERROR_VERBOSE.
1865
1866         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
1867         associative).
1868         Use it to check the computations.
1869         Use it to check `nonassoc' is honored.
1870         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
1871         `--yyerror-verbose'.
1872         (_AT_CHECK_CALC): Adjust to this option.

1874
1875 2000-10-02  Akim Demaille  <akim@epita.fr>
1876
1877         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
1878         the latter demonstrates a flaw in the handling of non debugging
1879         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
1880         was used in order to simplify:
1881
1882         #if YYDEBUG
1883         if (yydebug)
1884         {
1885         ...
1886         }
1887         #endif
1888
1889         into
1890
1891         if (yydebug)
1892         {
1893         ...
1894         }
1895
1896         unfortunately this leads to a CPP conflict when
1897         `--name-prefix=foo' is used since it produces `#define yydebug
1898         foodebug'.
1899
1900         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
1901         (YYDPRINTF): New macro.
1902         Spread its use.
1903         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
1904         the bison options.
1905         Also test `--verbose', `--defines' and `--name-prefix'.
1906

1909         Improve the readability of the produced parsers.
1910
1911         * src/bison.s1: Formatting changes.
1912         Improve the comment related to the `$' mark.
1913         (yydefault): Don't fall through to `yyresume': `goto' there.
1914         * src/output.c (output_parser): When the `$' is met, skip the end
1915         of its line.
1916         New variable, `number_of_dollar_signs', to check there's exactly
1917         one `$' in the parser skeleton.
1918
1919 2000-10-02  Akim Demaille  <akim@epita.fr>
1920
1921         * lib/xstrdup.c: New file, from the fileutils.
1922         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
1923         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
1924         instead of strlen + xmalloc + strcpy.
1925         * src/symtab.c (copys): Remove, use xstrdup instead.
1926
1927 2000-10-02  Akim Demaille  <akim@epita.fr>
1928
1929         * src/gram.h (associativity): New enum type which replaces the
1930         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
1931         `right_assoc', `left_assoc' and `non_assoc'.
1932         Adjust all dependencies.
1933         * src/reader.c: Formatting changes.
1934         (LTYPESTR): Don't define it, use it as a literal in
1935         `reader_output_yylsp'.
1936         * src/symtab.h (symbol_class): New enum type which replaces the
1937         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
1938         `sunknown', `stoken and `snterm'.
1939
1940 2000-10-02  Akim Demaille  <akim@epita.fr>
1941
1942         * src/getargs.c (fixed_outfiles): Rename as...
1943         (yaccflag): for consistency and accuracy.
1944         Adjust dependencies.
1945
1946 2000-10-02  Akim Demaille  <akim@epita.fr>
1947
1948         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
1949         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
1950         difficult and introduced a lot of core dump.  It turns out that
1951         Bison used an implementation of `xmalloc' based on `calloc', and
1952         at various places it does depend upon the initialization to 0.  I
1953         have not tried to isolate the pertinent places, and all the former
1954         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
1955         someone should address this issue.
1956
1957         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
1958         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
1959         files.

1964 2000-10-02  Akim Demaille  <akim@epita.fr>
1965
1966         Various anti-`extern in *.c' changes.
1967
1968         * src/system.h: Include `assert.h'.
1969
1970 2000-10-02  Akim Demaille  <akim@epita.fr>
1971
1972         * src/state.h (nstates, final_state, first_state, first_shift)

2051
2052         * src/output.c (token_actions): Introduce a temporary array,

2055
2056 2000-10-02  Akim Demaille  <akim@epita.fr>
2057
2058         `user_toknums' is output as a `short[]' in `output.c', while it is
2059         defined as a `int[]' in `reader.c'.  For consistency with the
2060         other output tables, `user_toknums' is now defined as a table of
2061         shorts.
2062
2063         * src/reader.c (user_toknums): Be a short table instead of an int

2076         order to get rid of the `static' prototypes.
2077         No longer use `register'.
2078         * src/output.h: New file.
2079         Propagate its inclusion in files explicitly prototyping functions
2080         from output.c.

2089         * src/closure.c: Formatting changes, topological sort over the
2090         functions, use of closure.h.
2091         (initialize_closure, finalize_closure):  Rename as...

2102         inclusion.
2103         Don't define PARAMS.
2104         * src/system.h: Define PARAMS.
2105         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

2107         definitions in config.h.

2267
2268         * src/Makefile.am (bison.simple): Fix the awk program: quote only
2269         the file name, not the whole `#line LINE FILE'.
2270
2271 2000-03-17  Akim Demaille  <akim@epita.fr>
2272
2273         On syntax errors, report the token on which we choked.
2274

2295         copy_comment.  Removed now unused `match', `ended',
2296         `cplus_comment'.
2297         (copy_comment, copy_string): Moved, to be visible from
2298         copy_definition.
2299

2301
2302         * src/reader.c (copy_string): Declare `static inline'.  No

2324
2325         Change the handling of @s so that they behave exactly like $s.
2326         There is now a pseudo variable @$ (readble and writable), location
2327         of the lhs of the rule (by default ranging from the location of
2328         the first symbol of the rhs, to the location of the last symbol,
2329         or, if the rhs is empty, YYLLOC).
2330
2331         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2332         yyval.
2333         (yyparse): When providing a default semantic action, provide a
2334         default location action.
2335         (after the $): No longer change `*YYLSP', just stack YYLOC the
2336         same way you stack YYVAL.
2337         * src/reader.c (read_declarations): Use warns.
2338         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2339         (copy_action, case '@'): Likewise.
2340         Use a standard error message, to save useless work from
2341         translators.
2342
2343 2000-03-17  Akim Demaille  <akim@epita.fr>
2344

2362
2363         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
2364         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2365         One `#if YYDEBUG' remains, since it uses variables which are
2366         defined only if `YYDEBUG != 0'.
2367
2368 2000-03-16  Akim Demaille  <akim@epita.fr>
2369
2370         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

2392         handled via src/Makefile.am.

2394         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
2395         autoheader.

2400         the proper line number and file name.
2401         (DEFS): Propagate the location of bison library files and of the
2402         locale files.
2403         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
2404         builddir.
2405         * acinclude.m4: Remove, replaced by the directory m4.
2406         * m4/Makefile.am (EXTRA_DIST): New variable.
2407         * m4/gettext.m4: New file, from the fileutils.

3053         (get_type, packsymbols):  Revised most error messages.
3054         Changed `fatal' to `warnxxx' to avoid aborting for error.
3055         Revised and use multiple warnxxx functions to avoid using VARARGS1.
3056         (read_declarations): Improve the error message for
3057         an invalid character.  Do not abort.
3058         (read_declarations, copy_guard, copy_action): Use
3059         printable_version to avoid unprintable characters in printed output.

3071         * src/main.c (main):
3072          If reader sees an error, don't process the grammar.
3073         (fatals): Updated to not use VARARGS1.
3074         (printable_version, int_to_string, warn, warni, warns, warnss)
3075         (warnsss): New error reporting functions.  Avoid abort for error.

3087         (literalchar, lex, parse_percent_token): Made tokenbuffer
3088         always contain the token.  This includes growing the token
3089         buffer while reading an integer.

3091         (parse_percent_token): Added % declarations as another
3092         way to specify the flags -n, -l, and -r.  Also added hooks for
3093         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
3094         major changes to files.c.
3095         (lex) Retain in the incoming stream a character following
3096         an incorrect '/'.
3097         (skip_white_space, lex):  Revised most error messages
3098         and changed fatal to warn to avoid aborting.
