1 2001-12-05 Akim Demaille <akim@epita.fr>
3 * src/nullable.c (set_nullable): Deobfuscate the handling of
5 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
8 2001-12-05 Akim Demaille <akim@epita.fr>
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

20 to be the same as the stack names.
21 (yyparse): yyptr is now union yyalloc *, not char *.

23 and may generate better code on some machines.
24 (yystpcpy): Use prototype if __STDC__ is defined, not just
25 if __cplusplus is defined.
27 2001-11-30 Akim Demaille <akim@epita.fr>

76 (yystrlen, yystpcpy): New functions.
78 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
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.

87 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
88 before their first uses.

98 if body instead of `;' to pacify GCC's warnings.
100 2001-11-30 Akim Demaille <akim@epita.fr>
102 Instead of mapping the LHS of unused rules to -1, keep the LHS

106 * src/print.c (print_grammar): Adjust.

137 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
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.
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.
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.
152 2001-11-29 Marc Autret <autret_m@epita.fr>

207 * src/closure.c (closure): Instead of looping over word in array
208 then bits in words, loop over bits in array.

2221 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
2222 `unlink': it's no longer used.

2237 * src/main.c (main): Don't use `atexit' to register `done', since
2238 it no longer has to remove tmp files, just call `output_files'
2239 when there are no errors.
2241 2000-11-02 Akim Demaille <akim@epita.fr>

2342 2000-10-04 Akim Demaille <akim@epita.fr>
2344 When a literal string is used to define two different tokens,
2345 `bison -v' segfaults.
2346 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
2348 * tests/regression.m4: New file.
2349 Include the core of the sample provided by Piotr Gackiewicz.

2373 translation, move some `\n' out of the translated strings.
2375 2000-10-02 Akim Demaille <akim@epita.fr>
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.
2383 * src/getargs.c (getargs): Support `--locations'.
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'.
2391 * tests/calc.m4: Test it.
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'.
2398 2000-10-02 Akim Demaille <akim@epita.fr>
2400 Also test parse error messages, including with YYERROR_VERBOSE.
2402 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
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.
2411 2000-10-02 Akim Demaille <akim@epita.fr>
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:
2432 unfortunately this leads to a CPP conflict when
2433 `--name-prefix=foo' is used since it produces `#define yydebug
2436 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
2437 (YYDPRINTF): New macro.
2439 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
2441 Also test `--verbose', `--defines' and `--name-prefix'.
2443 2000-10-02 Akim Demaille <akim@epita.fr>
2445 Improve the readability of the produced parsers.
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
2452 New variable, `number_of_dollar_signs', to check there's exactly
2453 one `$' in the parser skeleton.
2455 2000-10-02 Akim Demaille <akim@epita.fr>
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.
2463 2000-10-02 Akim Demaille <akim@epita.fr>
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

2479 (yaccflag): for consistency and accuracy.
2480 Adjust dependencies.
2482 2000-10-02 Akim Demaille <akim@epita.fr>
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.
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

2592 2000-10-02 Akim Demaille <akim@epita.fr>
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

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

2900 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

3573 * src/reader.c (reader_output_yylsp):
3575 (readgram): Use `#if 0' around code that accepted %command
3576 inside grammar rules: The documentation doesn't allow it,

3578 (parse_token_decl): Extended the %token
3579 declaration to allow a multi-character symbol as an alias.
3580 (parse_thong_decl): New function.
3581 (read_declarations): Added %thong declarations.

3590 Changed `fatal' to `warnxxx' to avoid aborting for error.
3591 Revised and use multiple warnxxx functions to avoid using VARARGS1.
3592 (read_declarations): Improve the error message for
3593 an invalid character. Do not abort.
3594 (read_declarations, copy_guard, copy_action): Use
3595 printable_version to avoid unprintable characters in printed output.
3596 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
3597 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):

3603 (output_rule_data): Implement noparserflag variable.
3604 Implement toknumflag variable.

3610 (printable_version, int_to_string, warn, warni, warns, warnss)
3611 (warnsss): New error reporting functions. Avoid abort for error.
3614 Added THONG and NOOP for alias processing.

3621 (lex): Use literalchar.
3622 (lex): Implemented "..." tokens.
3623 (literalchar, lex, parse_percent_token): Made tokenbuffer
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.
3631 (lex) Retain in the incoming stream a character following
3633 (skip_white_space, lex): Revised most error messages
3634 and changed fatal to warn to avoid aborting.
3635 (percent_table): Added %thong declarations.
3637 * src/gram.h: Comment changes.
