[bison.git] / ChangeLog
1 2001-12-05 Akim Demaille <akim@epita.fr>
2
3 * src/nullable.c (set_nullable): Deobfuscate the handling of
4 ritem.
5 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
6
7
8 2001-12-05 Akim Demaille <akim@epita.fr>
9
10 * src/gram.c, src/gram.h (ritem_print): New.
11 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
12 (This useless function was defined only to work around VMS linkers
13 that can't handle compilation units with variables only).
14 * src/reduce.c (dump_grammar): Use it to trace the construction of
15 ritem.
16
17 2001-12-04 Paul Eggert <eggert@twinsun.com>
18
19 * src/bison.simple (union yyalloc): Change member names
20 to be the same as the stack names.
21 (yyparse): yyptr is now union yyalloc *, not char *.
22 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
23 and may generate better code on some machines.
24 (yystpcpy): Use prototype if __STDC__ is defined, not just
25 if __cplusplus is defined.
26
27 2001-11-30 Akim Demaille <akim@epita.fr>
28
29 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
30 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
31 Gettext doesn't compile cleanly, and dies with -Werror.
32 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
33 Include WARNING_CFLAGS here.
34 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
35 before being defined.
36
37 2001-11-27 Paul Eggert <eggert@twinsun.com>
38
39 * lib/quotearg.h (quotearg_n, quotearg_n_style):
40 First arg is int, not unsigned.
41 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
42 (SIZE_MAX, UINT_MAX): New macros.
43 (quotearg_n_options): Abort if N is negative.
44 Avoid overflow check on hosts where size_t is 64 bits and int
45 is 32 bits, as overflow is impossible there.
46 Fix off-by-one typo that caused unnecessary reallocation.
47
48 2001-11-29 Paul Eggert <eggert@twinsun.com>
49
50 Name space cleanup in generated parser.
51
52 * doc/bison.texinfo (Bison Parser): Discuss system headers

54
55 * src/bison.simple:
56 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
57 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
58 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
59
60 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
61 on user names when possible.
62
63 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
64 Simplify test for whather <alloca.h> exists.
65
66 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
67
68 (<stdio.h>): Include if YYDEBUG.
69
70 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
71 ! defined (yyoverflow) && ! defined (yymemcpy).
72
73 (yymemcpy, yyparse): Rename local variables as needed so that
74 they all begin with 'yy'.
75
76 (yystrlen, yystpcpy): New functions.
77
78 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
79 All uses changed.
80
81 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
82 instead of relying on string.h functions. Use YYSTACK_ALLOC
83 and YYSTACK_FREE instead of malloc and free.
84
85 2001-11-30 Akim Demaille <akim@epita.fr>
86
87 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
88 before their first uses.

94
95 2001-11-30 Akim Demaille <akim@epita.fr>
96
97 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
98 if body instead of `;' to pacify GCC's warnings.
99
100 2001-11-30 Akim Demaille <akim@epita.fr>
101
102 Instead of mapping the LHS of unused rules to -1, keep the LHS
103 valid, but flag the rules as invalid.
104
105 * src/gram.h (rule_t): `useful' is a new member.
106 * src/print.c (print_grammar): Adjust.
107 * src/derives.c (set_derives): Likewise.
108 * src/reader.c (packgram, reduce_output): Likewise.
109 * src/reduce.c (reduce_grammar_tables): Likewise.

118
119 2001-11-30 Akim Demaille <akim@epita.fr>

123 (reduce_output): Adjust.
124 * tests/reduce.at (Useless Nonterminals): Adjust.
125
126 2001-11-30 Akim Demaille <akim@epita.fr>

132
133 2001-11-29 Paul Eggert <eggert@twinsun.com>
134
135 * src/bison.simple (YYSTACK_REALLOC): Remove.
136 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
137 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
138 New macros.
139 (union yyalloc): New type.
140 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
141 an arbitrary restriction on hosts where size_t is wider than int.
142
143 (yyparse): Don't dump core if alloca or malloc fails; instead, report
144 a parser stack overflow. Allocate just one block of memory for all
145 three stacks, instead of allocating three blocks; this typically is
146 faster and reduces fragmentation.
147
148 Do not limit the number of items in the stack to a value that fits
149 in 'int', as this is an arbitrary limit on hosts with 64-bit
150 size_t and 32-bit int.
151

2007 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
2008 * src/reader.c (read_declarations): Adjust.
2009 * src/files.c (open_files): Don't call `compute_base_names', don't
2010 compute `attrsfile' since they depend upon data which might be
2011 *in* the input file now.
2012 (output_files): Do it here.
2013 * src/output.c (output_headers): Document the fact that this patch
2014 introduces a guaranteed SEGV for semantic parsers.

2041 2000-12-20 Akim Demaille <akim@epita.fr>

2073 (stringappend): Be just like strcat but allocate.

2116 2000-12-19 Akim Demaille <akim@epita.fr>
2117
2118 * src/files.c (open_files): Yipee! We no longer need all the code

2152 prevents type checking.
2153 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't

2205 `address' for consistency. Qualify it `const'.
2206 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
2207 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify

2350 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
2351 properly.
2352
2353 2000-10-04 Akim Demaille <akim@epita.fr>
2354
2355 * src/reader.c (parse_expect_decl): Keep `count' within the size
2356 of `buffer'.
2357 From Neil Booth.
2358
2359 2000-10-02 Paul Eggert <eggert@twinsun.com>
2360
2361 * bison.s1 (yyparse): Assign the default value
2362 unconditionally, to avoid a GCC warning and make the parser a
2363 tad smaller.
2364
2365 2000-10-02 Akim Demaille <akim@epita.fr>
2366
2367 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
2368 options.
2369
2370 2000-10-02 Akim Demaille <akim@epita.fr>
2371
2372 * src/derives.c, src/print.c, src/reduce.c: To ease the
2373 translation, move some `\n' out of the translated strings.
2374
2375 2000-10-02 Akim Demaille <akim@epita.fr>
2376
2377 The location tracking mechanism is precious for parse error
2378 messages. Nevertheless, it is enabled only when `@n' is used in
2379 the grammar, which is a different issue (you can use it in error
2380 message, but not in the grammar per se). Therefore, there should
2381 be another means to enable it.
2382
2383 * src/getargs.c (getargs): Support `--locations'.
2384 (usage): Report it.
2385 * src/getargs.h (locationsflag): Export it.
2386 * src/lex.c (percent_table): Support `%locations'.
2387 * src/reader.c (yylsp_needed): Remove this variable, now replaced
2388 with `locationsflag'.
2389 * doc/bison.texinfo: Document `--locations' and `%locations'.
2390 Sort the options.
2391 * tests/calc.m4: Test it.
2392
2393 For regularity of the names, replace each
2394 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
2395 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
2396 In addition replace each `flag' with `_flag'.
2397
2398 2000-10-02 Akim Demaille <akim@epita.fr>
2399
2400 Also test parse error messages, including with YYERROR_VERBOSE.
2401
2402 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
2403 associative).
2404 Use it to check the computations.
2405 Use it to check `nonassoc' is honored.
2406 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
2407 `--yyerror-verbose'.
2408 (_AT_CHECK_CALC): Adjust to this option.
2409 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
2410
2411 2000-10-02 Akim Demaille <akim@epita.fr>
2412
2413 Test also `--verbose', `--defines' and `--name-prefix'. Testing
2414 the latter demonstrates a flaw in the handling of non debugging
2415 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
2416 was used in order to simplify:
2417
2418 #if YYDEBUG
2419 if (yydebug)
2420 {
2421 ...
2422 }
2423 #endif
2424
2425 into
2426
2427 if (yydebug)
2428 {
2429 ...
2430 }
2431
2432 unfortunately this leads to a CPP conflict when
2433 `--name-prefix=foo' is used since it produces `#define yydebug
2434 foodebug'.
2435
2436 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
2437 (YYDPRINTF): New macro.
2438 Spread its use.
2439 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
2440 the bison options.
2441 Also test `--verbose', `--defines' and `--name-prefix'.
2442
2443 2000-10-02 Akim Demaille <akim@epita.fr>
2444
2445 Improve the readability of the produced parsers.
2446
2447 * src/bison.s1: Formatting changes.
2448 Improve the comment related to the `$' mark.
2449 (yydefault): Don't fall through to `yyresume': `goto' there.
2450 * src/output.c (output_parser): When the `$' is met, skip the end
2451 of its line.
2452 New variable, `number_of_dollar_signs', to check there's exactly
2453 one `$' in the parser skeleton.
2454
2455 2000-10-02 Akim Demaille <akim@epita.fr>
2456
2457 * lib/xstrdup.c: New file, from the fileutils.
2458 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
2459 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
2460 instead of strlen + xmalloc + strcpy.
2461 * src/symtab.c (copys): Remove, use xstrdup instead.
2462
2463 2000-10-02 Akim Demaille <akim@epita.fr>
2464
2465 * src/gram.h (associativity): New enum type which replaces the
2466 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
2467 `right_assoc', `left_assoc' and `non_assoc'.
2468 Adjust all dependencies.
2469 * src/reader.c: Formatting changes.
2470 (LTYPESTR): Don't define it, use it as a literal in
2471 `reader_output_yylsp'.
2472 * src/symtab.h (symbol_class): New enum type which replaces the
2473 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
2474 `sunknown', `stoken and `snterm'.
2475
2476 2000-10-02 Akim Demaille <akim@epita.fr>
2477
2478 * src/getargs.c (fixed_outfiles): Rename as...
2479 (yaccflag): for consistency and accuracy.
2480 Adjust dependencies.
2481
2482 2000-10-02 Akim Demaille <akim@epita.fr>
2483
2484 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
2485 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
2486 difficult and introduced a lot of core dump. It turns out that
2487 Bison used an implementation of `xmalloc' based on `calloc', and
2488 at various places it does depend upon the initialization to 0. I
2489 have not tried to isolate the pertinent places, and all the former
2490 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
2491 someone should address this issue.
2492
2493 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
2494 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
2495 files.
2496 Adjust dependencies.

2501
2502 Various anti-`extern in *.c' changes.
2503
2504 * src/system.h: Include `assert.h'.
2505
2506 2000-10-02 Akim Demaille <akim@epita.fr>
2507
2508 * src/state.h (nstates, final_state, first_state, first_shift)
2509 (first_reduction): Move their exportation from here...
2510 * src/LR0.h: to here.
2511 Adjust dependencies.
2512 * src/getargs.c (statisticsflag): New variable.
2513 Add support for `--statistics'.
2514 Adjust dependencies.
2515
2516 Remove a lot of now useless `extern' statements in most files.
2517
2518 2000-10-02 Akim Demaille <akim@epita.fr>
2519
2520 * src/LR0.h: New file.

2538 * src/conflicts.h: New file.
2539 Propagate its inclusion.
2540
2541 2000-10-02 Akim Demaille <akim@epita.fr>
2542

2589 YYDEFACT, that makes it possible for this function to use
2590 output_short_table.
2591
2592 2000-10-02 Akim Demaille <akim@epita.fr>
2593
2594 `user_toknums' is output as a `short[]' in `output.c', while it is
2595 defined as a `int[]' in `reader.c'. For consistency with the
2596 other output tables, `user_toknums' is now defined as a table of
2597 shorts.
2598
2599 * src/reader.c (user_toknums): Be a short table instead of an int
2600 table.
2601 Adjust dependencies.

2608
2609 2000-10-02 Akim Demaille <akim@epita.fr>
2610
2611 * src/output.c (output): Topological sort of the functions, in
2612 order to get rid of the `static' prototypes.

2614 * src/output.h: New file.
2615 Propagate its inclusion in files explicitly prototyping functions
2616 from output.c.

2638 inclusion.
2639 Don't define PARAMS.
2640 * src/system.h: Define PARAMS.
2641 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
2642 purpose of config.h. system.h must not try to fix wrong
2643 definitions in config.h.
2644
2645 2000-09-20 Akim Demaille <akim@epita.fr>
2646
2647 * src/derives.h: New file.

2805 the file name, not the whole `#line LINE FILE'.
2806

2808
2809 On syntax errors, report the token on which we choked.

2843

2860
2861 Change the handling of @s so that they behave exactly like $s.
2862 There is now a pseudo variable @$ (readble and writable), location
2863 of the lhs of the rule (by default ranging from the location of
2864 the first symbol of the rhs, to the location of the last symbol,
2865 or, if the rhs is empty, YYLLOC).
2866
2867 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2868 yyval.
2869 (yyparse): When providing a default semantic action, provide a
2870 default location action.
2871 (after the $): No longer change `*YYLSP', just stack YYLOC the
2872 same way you stack YYVAL.
2873 * src/reader.c (read_declarations): Use warns.
2874 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2875 (copy_action, case '@'): Likewise.
2876 Use a standard error message, to save useless work from
2877 translators.

2898
2899 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
2900 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2901 One `#if YYDEBUG' remains, since it uses variables which are
2902 defined only if `YYDEBUG != 0'.

2904 2000-03-16 Akim Demaille <akim@epita.fr>
2905

2942 * m4/Makefile.am (EXTRA_DIST): New variable.
2943 * m4/gettext.m4: New file, from the fileutils.

3624 always contain the token. This includes growing the token
3625 buffer while reading an integer.
3626 (parse_percent_token): Replaced if-else statement with percent_table.
3627 (parse_percent_token): Added % declarations as another
3628 way to specify the flags -n, -l, and -r. Also added hooks for
3629 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
3630 major changes to files.c.
