ChangeLog

   1 2001-11-30  Akim Demaille  <akim@epita.fr>
   2
   3         Instead of mapping the LHS of unused rules to -1, keep the LHS
   4         valid, but flag the rules as invalid.
   5
   6         * src/gram.h (rule_t): `useful' is a new member.
   7         * src/print.c (print_grammar): Adjust.

  19
  20 2001-11-30  Akim Demaille  <akim@epita.fr>
  21
  22         * src/reduce.c (nonterminals_reduce): Instead of throwing away
  23         useless nonterminals, move them at the end of the symbol arrays.
  24         (reduce_output): Adjust.
  25         * tests/reduce.at (Useless Nonterminals): Adjust.
  26
  27 2001-11-30  Akim Demaille  <akim@epita.fr>
  28
  29         * src/reduce.c: Various comment/formatting changes.
  30         (nonterminals_reduce): New, extracted from...
  31         (reduce_grammar_tables): here.
  32         (reduce_grammar): Call nonterminals_reduce.
  33
  34 2001-11-29  Paul Eggert  <eggert@twinsun.com>
  35
  36         * src/bison.simple (YYSTACK_REALLOC): Remove.
  37         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
  38         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
  39         New macros.
  40         (union yyalloc): New type.
  41         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
  42         an arbitrary restriction on hosts where size_t is wider than int.
  43
  44         (yyparse): Don't dump core if alloca or malloc fails; instead, report
  45         a parser stack overflow.  Allocate just one block of memory for all
  46         three stacks, instead of allocating three blocks; this typically is
  47         faster and reduces fragmentation.
  48
  49         Do not limit the number of items in the stack to a value that fits
  50         in 'int', as this is an arbitrary limit on hosts with 64-bit
  51         size_t and 32-bit int.
  52
  53 2001-11-29  Marc Autret  <autret_m@epita.fr>

 111 2001-11-28  Akim Demaille  <akim@epita.fr>
 112
 113         * src/closure.c (closure): No longer optimize the special case

 482         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,

 484         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

 508         arg_offset.
 509         arg is const.

 607         * src/reader.c (parse_union_decl): Output yystype/YYSTYPE as we do
 608         with yyltype/YYLTYPE.  This allows inclusion of the generated

1823         * configure.in: Require Autoconf 2.50.
1824         Update to gettext 0.10.38.
1825
1826 2001-03-16  Akim Demaille  <akim@epita.fr>
1827

1839
1840         * m4/strerror_r.m4: New.

1847
1848 2001-02-21  Akim Demaille  <akim@epita.fr>
1849
1850         * src/reader.c (gensym): `gensym_count' is your own.
1851         Use a static buf to create the symbol name, as token_buffer is no
1852         longer a buffer.
1853
1854 2001-02-08  Akim Demaille  <akim@epita.fr>
1855
1856         * src/conflicts.c (conflict_report): Be sure not to append to res
1857         between two calls, which could happen if both first sprintf were
1858         skipped, but not the first cp += strlen.
1859
1860 2001-02-08  Akim Demaille  <akim@epita.fr>
1861
1862         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
1863         New, from fileutils 4.0.37.
1864         * configure.in: Require Autoconf 2.49c.  I took some time before
1865         making this decision.  This is the only way out for portability
1866         issues in Bison, it would mean way too much duplicate effort to
1867         import in Bison features implemented in 2.49c since 2.13.
1868         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

1876
1877         Get rid of the ad hoc handling of token_buffer in the scanner: use
1878         the obstacks.
1879
1880         * src/lex.c (token_obstack): New.
1881         (init_lex): Initialize it.  No longer call...

1886
1887         * src/lex.h: Rename all the tokens:
1888         s/\bENDFILE\b/tok_eof/g;
1889         s/\bIDENTIFIER\b/tok_identifier/g;
1890         etc.
1891         Let them be enums, not #define, to ease debugging.
1892         Adjust all the code.
1893
1894 2001-01-18  Akim Demaille  <akim@epita.fr>
1895
1896         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

1898
1899 2001-01-18  Akim Demaille  <akim@epita.fr>
1900
1901         Since we now use obstacks, more % directives can be enabled.
1902
1903         * src/lex.c (percent_table): Also accept `%yacc',
1904         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
1905         `%debug'.
1906         Handle the actions for `%semantic_parser' and `%pure_parser' here,
1907         instead of returning a token.
1908         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
1909         * src/reader.c (read_declarations): Adjust.
1910         * src/files.c (open_files): Don't call `compute_base_names', don't
1911         compute `attrsfile' since they depend upon data which might be
1912         *in* the input file now.
1913         (output_files): Do it here.
1914         * src/output.c (output_headers): Document the fact that this patch
1915         introduces a guaranteed SEGV for semantic parsers.
1916         * doc/bison.texinfo: Document them.
1917         * tests/suite.at: Exercise these %options.
1918
1919 2000-12-20  Akim Demaille  <akim@epita.fr>
1920

1933         * src/files.c (open_files): Fix the computation of short_base_name
1934         in the case of `-o foo.tab.c'.
1935
1936 2000-12-20  Akim Demaille  <akim@epita.fr>
1937
1938         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
1939         (copy_dollar): Now that everything uses obstacks, get rid of the
1940         FILE * parameters.
1941
1942 2000-12-20  Akim Demaille  <akim@epita.fr>
1943
1944         * src/files.c (open_files): Actually the `.output' file is based
1945         on the short_base_name, not base_name.
1946         * tests/suite.at (Checking output file names): Adjust.
1947
1948 2000-12-20  Akim Demaille  <akim@epita.fr>
1949
1950         * src/bison.s1: Remove, we now use directly...

1974         (stringappend): Be just like strcat but allocate.
1975         (base_names): Eve out from open_files.
1976         Try to simplify the rather hairy computation of base_name and
1977         short_base_name.
1978         (open_files): Use it.
1979         * tests/suite.at (Checking output file names): New test.

1989
1990 2000-12-19  Akim Demaille  <akim@epita.fr>
1991

1996
1997 2000-12-19  Akim Demaille  <akim@epita.fr>
1998
1999         Let the handling of the skeleton files be local to the procedures
2000         that use it.
2001

2018

2051         * lib/obstack.h: Formatting changes.
2052         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
2053         prevents type checking.
2054         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
2055         cast the value to (void *): assigning a `foo *' to a `void *'
2056         variable is valid.

2093
2094 2000-11-07  Akim Demaille  <akim@epita.fr>
2095
2096         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
2097         Merge in a single CPP if/else.

2102         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
2103         argument `data' for consistency with the prototypes.

2117
2118 2000-11-03  Akim Demaille  <akim@epita.fr>
2119
2120         For some reason, this was not applied.
2121
2122         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

2137         Use `obstack_save'.
2138         * src/main.c (main): Don't use `atexit' to register `done', since
2139         it no longer has to remove tmp files, just call `output_files'
2140         when there are no errors.
2141
2142 2000-11-02  Akim Demaille  <akim@epita.fr>

2246         `bison -v' segfaults.
2247         Reported by Piotr Gackiewicz, and fixed by Neil Booth.

2255

2260 2000-10-02  Paul Eggert  <eggert@twinsun.com>
2261
2262         * bison.s1 (yyparse): Assign the default value
2263         unconditionally, to avoid a GCC warning and make the parser a
2264         tad smaller.
2265
2266 2000-10-02  Akim Demaille  <akim@epita.fr>
2267

2272
2273         * src/derives.c, src/print.c, src/reduce.c: To ease the

2275
2276 2000-10-02  Akim Demaille  <akim@epita.fr>
2277
2278         The location tracking mechanism is precious for parse error
2279         messages.  Nevertheless, it is enabled only when `@n' is used in
2280         the grammar, which is a different issue (you can use it in error
2281         message, but not in the grammar per se).  Therefore, there should
2282         be another means to enable it.
2283
2284         * src/getargs.c (getargs): Support `--locations'.
2285         (usage): Report it.
2286         * src/getargs.h (locationsflag): Export it.
2287         * src/lex.c (percent_table): Support `%locations'.
2288         * src/reader.c (yylsp_needed): Remove this variable, now replaced
2289         with `locationsflag'.
2290         * doc/bison.texinfo: Document `--locations' and `%locations'.
2291         Sort the options.
2292         * tests/calc.m4: Test it.
2293
2294         For regularity of the names, replace each
2295         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
2296         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
2297         In addition replace each `flag' with `_flag'.
2298
2299 2000-10-02  Akim Demaille  <akim@epita.fr>
2300
2301         Also test parse error messages, including with YYERROR_VERBOSE.
2302
2303         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
2304         associative).
2305         Use it to check the computations.
2306         Use it to check `nonassoc' is honored.
2307         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
2308         `--yyerror-verbose'.
2309         (_AT_CHECK_CALC): Adjust to this option.
2310         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
2311
2312 2000-10-02  Akim Demaille  <akim@epita.fr>
2313
2314         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
2315         the latter demonstrates a flaw in the handling of non debugging
2316         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
2317         was used in order to simplify:
2318
2319         #if YYDEBUG
2320         if (yydebug)
2321         {
2322         ...
2323         }
2324         #endif
2325
2326         into
2327
2328         if (yydebug)
2329         {
2330         ...
2331         }
2332
2333         unfortunately this leads to a CPP conflict when
2334         `--name-prefix=foo' is used since it produces `#define yydebug
2335         foodebug'.
2336
2337         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
2338         (YYDPRINTF): New macro.
2339         Spread its use.
2340         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
2341         the bison options.
2342         Also test `--verbose', `--defines' and `--name-prefix'.
2343
2344 2000-10-02  Akim Demaille  <akim@epita.fr>
2345
2346         Improve the readability of the produced parsers.
2347
2348         * src/bison.s1: Formatting changes.
2349         Improve the comment related to the `$' mark.
2350         (yydefault): Don't fall through to `yyresume': `goto' there.
2351         * src/output.c (output_parser): When the `$' is met, skip the end
2352         of its line.
2353         New variable, `number_of_dollar_signs', to check there's exactly
2354         one `$' in the parser skeleton.
2355
2356 2000-10-02  Akim Demaille  <akim@epita.fr>
2357
2358         * lib/xstrdup.c: New file, from the fileutils.
2359         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
2360         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
2361         instead of strlen + xmalloc + strcpy.
2362         * src/symtab.c (copys): Remove, use xstrdup instead.
2363
2364 2000-10-02  Akim Demaille  <akim@epita.fr>
2365
2366         * src/gram.h (associativity): New enum type which replaces the
2367         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
2368         `right_assoc', `left_assoc' and `non_assoc'.
2369         Adjust all dependencies.
2370         * src/reader.c: Formatting changes.
2371         (LTYPESTR): Don't define it, use it as a literal in
2372         `reader_output_yylsp'.
2373         * src/symtab.h (symbol_class): New enum type which replaces the
2374         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
2375         `sunknown', `stoken and `snterm'.
2376
2377 2000-10-02  Akim Demaille  <akim@epita.fr>
2378
2379         * src/getargs.c (fixed_outfiles): Rename as...

2381         Adjust dependencies.
2382
2383 2000-10-02  Akim Demaille  <akim@epita.fr>
2384
2385         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
2386         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
2387         difficult and introduced a lot of core dump.  It turns out that
2388         Bison used an implementation of `xmalloc' based on `calloc', and
2389         at various places it does depend upon the initialization to 0.  I
2390         have not tried to isolate the pertinent places, and all the former
2391         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
2392         someone should address this issue.
2393
2394         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
2395         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

2407 2000-10-02  Akim Demaille  <akim@epita.fr>
2408
2409         * src/state.h (nstates, final_state, first_state, first_shift)

2487 2000-10-02  Akim Demaille  <akim@epita.fr>
2488
2489         * src/output.c (token_actions): Introduce a temporary array,

2491         output_short_table.
2492
2493 2000-10-02  Akim Demaille  <akim@epita.fr>
2494
2495         `user_toknums' is output as a `short[]' in `output.c', while it is
2496         defined as a `int[]' in `reader.c'.  For consistency with the
2497         other output tables, `user_toknums' is now defined as a table of
2498         shorts.
2499
2500         * src/reader.c (user_toknums): Be a short table instead of an int
2501         table.

2511
2512         * src/output.c (output): Topological sort of the functions, in
2513         order to get rid of the `static' prototypes.
2514         No longer use `register'.
2515         * src/output.h: New file.
2516         Propagate its inclusion in files explicitly prototyping functions
2517         from output.c.

2539         inclusion.
2540         Don't define PARAMS.
2541         * src/system.h: Define PARAMS.
2542         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
2543         purpose of config.h.  system.h must not try to fix wrong

2707
2708 2000-03-17  Akim Demaille  <akim@epita.fr>
2709
2710         On syntax errors, report the token on which we choked.
2711

2732         copy_comment.  Removed now unused `match', `ended',
2733         `cplus_comment'.
2734         (copy_comment, copy_string): Moved, to be visible from
2735         copy_definition.

2738

2761
2762         Change the handling of @s so that they behave exactly like $s.
2763         There is now a pseudo variable @$ (readble and writable), location
2764         of the lhs of the rule (by default ranging from the location of
2765         the first symbol of the rhs, to the location of the last symbol,
2766         or, if the rhs is empty, YYLLOC).
2767
2768         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2769         yyval.
2770         (yyparse): When providing a default semantic action, provide a
2771         default location action.
2772         (after the $): No longer change `*YYLSP', just stack YYLOC the
2773         same way you stack YYVAL.
2774         * src/reader.c (read_declarations): Use warns.
2775         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2776         (copy_action, case '@'): Likewise.
2777         Use a standard error message, to save useless work from
2778         translators.
2779
2780 2000-03-17  Akim Demaille  <akim@epita.fr>
2781

2799
2800         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
2801         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2802         One `#if YYDEBUG' remains, since it uses variables which are
2803         defined only if `YYDEBUG != 0'.
2804
2805 2000-03-16  Akim Demaille  <akim@epita.fr>
2806
2807         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

2837         the proper line number and file name.
2838         (DEFS): Propagate the location of bison library files and of the
2839         locale files.
2840         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
2841         builddir.
2842         * acinclude.m4: Remove, replaced by the directory m4.
2843         * m4/Makefile.am (EXTRA_DIST): New variable.
2844         * m4/gettext.m4: New file, from the fileutils.
