24 * tests/torture.at (Exploding the Stack Size with Alloca): Set
25 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
26 otherwise, we're not testing alloca. Unfortunately there's no
27 simple way to consult HAVE_ALLOCA here.

29 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
30 for yymsg, too.
31
32 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
33 hand. This avoids a warning about comparing int to size_t when
34 GCC warnings are enabled.

38 * NEWS: Bison-generated parsers no longer default to using the
39 alloca function (when available) to extend the parser stack, due
40 to widespread problems in unchecked stack-overflow detection.
41 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
42 responsibility to set it to a positive value. This lets the user
43 specify a value that is not a preprocessor constant.
44 * data/yacc.c (YYMAXDEPTH): Likewise.
45 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
46 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
47 to be a compile-time constant. However, explain the constraints on it.
48 Also, explain the constraints on YYINITDEPTH.
49 (Table of Symbols): Explain that alloca is no longer the default.
50 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
51 to 1.

58 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
59 (parser::state_type, parser::semantic_type, parser::location_type):
60 Private, not public.
61 (parser::parse): Return ints, not bool.
62 Returning a bool introduces a problem: 0 corresponds to false, and
63 it seems weird to return false on success. Returning true changes
64 the conventions for yyparse.
65 Alternatively we could return void and send an exception.
66 There is no clear consensus (yet?).
67 (state_stack, semantic_stack, location_stack): Rename as...
68 (state_stack_type, semantic_stack_type, location_stack_type): these.
69 Private, not public.

84 the user code, so that needed headers for the filename type can be
85 included first.

99 (semantic_type, state_stack, state_type, token_number_type, stack)
100 (slice, traits, parser::yylloc, parser::yylval): these.

111 Remove uses of 'short int' and 'unsigned short int'. This raises
112 some arbitrary limits. It uses more memory but nowadays that's
113 not much of an issue.
114
115 This change does not affect the generated parsers; that's a different
116 task, as some users will want to conserve memory there.
117
118 Ideally we should use size_t to represent all object counts, and
119 something like ptrdiff_t to represent signed differences of object
120 counts; but that will require more code-cleanup than I have the
121 time to do right now.
122
123 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
124 Use size_t, not int or short int, to count objects.
125 * src/closure.c (nritemset, closure): Likewise.
126 * src/closure.h (nritemset, closure): Likewise.

137 errs, reductions): Likewise.
138 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
139 Likewise.
140 * src/tables.c (vector_number, tally, action_number,
141 ACTION_NUMBER_MINIMUM): Likewise.

159 Parenthesize rhs to avoid obscure problems with mistakes like
160 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.

210 Fix some problems reported by twlevo at xs4all.
211 * src/symtab.c (symbol_new): Report an error if the input grammar
212 contains too many symbols. This is better than calling abort() later.

245 pseudo namespace.
246 Adjust uses.
247 (b4_parse_param_decl): Remove the leading comma as it is now only
248 called as unique argument list.
249 (Parser::Parser): Remove the constructor accepting a location and
250 an initial debugging level.
251 Remove from the other ctor the argument for the debugging level.
252 (debug_level_type, debug_level, set_debug_level): New.

268 not 2, since it's not portable to subtract 1 from the start of an
269 array. The new item 0 is never set or used. All uses changed.

278 the normal case and one for the error case. Just use the
279 first one uniformly. Problem reported by Frank Heckenbach.
280 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
281 use exactly the same macro in both places.
282 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
283 so that the normal-case YYRHSLOC works for the error case too.
284 All uses changed.
285 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
286 (YYLLOC_DEFAULT): Use the same macro as glr.c.
287 * doc/bison.texinfo (Location Default Action): Don't claim that
288 we have an array of locations. Use the same macro for both glr
289 and lalr parsers. Mention YYRHSLOC. Mention what happens when
290 the index is 0.

304
305 * src/relation.h (relation_print, relation_digraph):
306 Relation sizes are of type relation_node, not size_t (this is
307 merely a doc fix, since the two types are equivalent).
308 (relation_transpose): Relation sizes are of type relation_node,
309 not int.

317
318 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
68b082af 319 specifying whether the test should be skipped. Use it tp
337116ba 320 specify that the [%defines %skeleton "lalr1.cc"] tests currently
68b082af 321 fail on some hosts, and should be skipped.

326 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
327 unless otherwise specified below.
328
329 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
330 to allocate kernel_base, kernel_items, kernel_size, since
331 they needn't be initialized to 0.
332 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
333 * src/closure.c (new_closure): Likewise, for itemset.

350 (pack_table): Likewise for base, pos, check.
351 (tables_generate): Likewise for width.
352
353 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
354 for initial core. Just have a separate core, so we needn't worry
355 about whether kernel_size and kernel_base are initialized.
356
357 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
358 kernel_size, kernel_items): Remove unnecessary initialization.

367 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
368 This is because all callers pass unsigned int.
369 * src/closure.h (new_closure): Likewise.
370
371 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
372 (build_relations): Initialize includes[i] in all cases.
373 * src/reader.c (packgram): Always initialize rules[ruleno].prec
374 and rules[ruleno].precsym. Initialize members in order.
375 * src/relation.c (relation_transpose): Always initialize new_R[i]
376 and end_R[i].
377 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
378
379 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
380 conflict_list[0] was always 0, but now it isn't initialized.
381
382 * src/table.c (table_grow): When conflict_table grew, the grown
383 area wasn't cleared. Fix this.

392 GOTO_NUMBER_MAXIMUM, since we occasionally compute
393 ngotos + 1 without checking for overflow.
394 (build_relations): Use END_NODE, not -1, to denote end of edges.
395 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
396 build_relations): Use goto_number, not int, for goto numbers.

519 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
520 whether the reducion was empty or not. This leaves room to
521 improve the use of YYLLOC_DEFAULT in such a case.
522 lalr1.cc is still experimental, so changing this is acceptable.
523 And finally, there are probably not many users who changed the
524 handling of locations in GLR, so changing is admissible too.

527 empty reduction, set @$ to an empty location ending the previously

670 Bison directive from the Bison file to the invocation of this
671 macro, so that these directives are passed to
672 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
673 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
674 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
675 the extra Bison directives instead of the whole series.
676 Change the grammar so that there are recoverable errors, and
677 unrecoverable errors. Now we can have the parser give up before
678 consuming the whole input. As a result we now can observe that
679 the lookahead is freed when needed.
680 Change the parser source to parse argv[1] instead of a hard coded
681 string.
682 Simplify yylex, and give a value and location to EOF.
683 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
684 passed directives already coded in the file.
685 Add some tests to check the location of "error".
686 For some tests, the C++ parser is correct, and not yacc.c.
687 For other tests, they provide different, but unsatisfying, values,
688 so keep the C++ value so that at least one parser is "correct"
689 according to the test suite.

869 Spent a few hours checking out which prerequisite versions the
870 current sources actually require. I went all the way back to
871 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
872 a seemingly endless set of combinations of versions more recent
873 than that. The bottom line is that the current sources require
874 fairly recent versions of the build tools, and it'll be some work
875 to change this.
876 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
877 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
878 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.

1391 When reducing initial empty rules, Bison parser read an initial
1392 location that is not defined. This results in garbage, and that

1690 The problem was that GLR parsers did not conform to the C standard,
1691 because actions like { $1 = $2 + $3; } expanded to expressions
1692 that invoked YYFILL in separate subexpressions, and YYFILL assigned
1693 to a local variable. The C standard says that expressions
1694 like (var = f ()) + (var = f ()) have undefined behavior.
1695 Another problem was that GCC sometimes issues warnings that
1696 yyfill and its parameters are unused.
1697
1698 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
1699 as possibly unused.
1700 (yyfill): New function.
1701 (YYFILL): Use it.
1702 (yyuserAction): Change type of yynormal to bool, so that it matches
1703 the new yyfill signature. Mark it as possibly unused.

1706 Follow up on a bug I reported in February, where a Bison-generated
1707 parser can loop. Provide a test case and a fix for yacc.c. I

1709 The original bug report is in:

1712 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
1713 macro's size was becoming unwieldy.
1714 (yyerrlab): Do not discard an empty lookahead symbol, as this
1715 might destroy garbage.
1716 (yyerrorlab): New label, with the old contents of YYERROR,
1717 plus the following change: pop the stack of rhs corresponding
1718 to the production that invoked YYERROR. That is how Yacc
1719 behaves, and POSIX requires this behavior.
1720 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
1721 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
1722 Define 'alarm' to do nothing if unistd.h is not available.
1723 Add a new rule "exp: '-' error;" to test the above change to
1724 data/yacc.c. Use 'alarm' to abort any test taking longer than
1725 10 seconds, as it's probably looping.
1726 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
1727 Also, the new yacc.c generates two fewer diagnostics for an
1728 existing test.

2082 depend on *loc, so that the reader doesn't give the the false
2083 impression that *loc is initialized.
2084 (<INITIAL>"%%"): Do not bother setting code_start, since its value

2356 we don't need to worry about yyerrlab1 being reported as an
2357 "unused label" by non-GCC C compilers. The downside is that if
2358 locations are used then a couple of statements are duplicated each
2359 time YYERROR is invoked, but the upside is that the warnings
2360 should vanish.

2378 popped). This means that the initial elements will not be freed
2379 explicitly, as is the case in yacc.c; it is not a problem, as
2380 these elements have fake values.

2491 * src/conflicts.c (conflict_report):
2492 Renamed from conflict_report_yacc, removing the old
2493 'conflict_report'. Translate the entire conflict report at once,
2494 so that we don't assume that "," has the same interpretation in
2495 all languages.
2496 (conflicts_output): Use Yacc-style conflict report for each state,
2497 instead of our more-complicated style.
2498 (conflicts_print): Use Yacc-style conflict report, except print
2499 the input file name when not emulating Yacc.

2517 * data/yacc.c (yyparse): New local var yylerrsp, to record the
2518 top of the location stack's error locations.
2519 (yyerrlab): Set it. When discarding a token, push its location
2520 onto yylerrsp so that we don't lose track of the error's end.
2521 (yyerrlab1): Now is only the target of YYERROR, so that we can
2522 properly record the location of the action that failed. For GCC
2523 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
2524 GCC warning about yyerrlab1 being unused if YYERROR is unused.
2525 (yyerrlab2): New label, which yyerrlab now falls through to.
2526 Compute the error's location by applying YYLLOC_DEFAULT to
2527 the locations of all the symbols that went into the error.
2528 * doc/bison.texinfo (Location Default Action): Mention that
2529 YYLLOC_DEFAULT is also invoked for syntax errors.
2530 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

2589 If the user does not define YYSTYPE as a macro, Bison now declares it
2590 using typedef instead of defining it as a macro. POSIX requires this.
2591 For consistency, YYLTYPE is also declared instead of defined.
2592
2593 %union directives can now have a tag before the `{', e.g., the
2594 directive `%union foo {...}' now generates the C code
2595 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
2596 The default union tag is `YYSTYPE', for compatibility with Solaris 9
2597 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
2598 instead of `yyltype'.
2599
2600 `yystype' and `yyltype' are now obsolescent macros instead of being

3595 Use new @ escapes consistently. Represent brackets with @{ and @}
3596 rather than @<:@ and @:>@, since this works a bit better with dumb
3597 editors like vi. Represent @ with @@, since @ is now consistently
3598 an escape. Use @oline@ and @ofile@ rather than __oline__ and
3599 __ofile__, to avoid unexpected expansions. Similarly, use @output
3600 rather than #output.
3601
3602 * data/c.m4 (b4_copyright): Omit file name from comment, since
3603 the file name could contain "*/".
3604 (b4_synclines_flag): Don't quote the 2nd argument; it should already
3605 be quoted. All uses changed.

3619 mishandled funny characters in file names, and anyway it isn't
3620 needed any more.
3621 * data/yacc.c: Likewise.

3645 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
3646 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
3647 Use new escapes @{ and @} for [ and ].
3648
3649 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
3650 them with auto vars.
3651 Switch to new escape scheme, where @ is the escape character uniformly.
3652 Abort if a stray escape character is found. Avoid unbounded input
3653 buffer when parsing non-escaped text.

3664 table.
3665 (yygetLRActions, yyrecoverParseError): Use them.

3667 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
3668 counted in the token inserted at end of file. Now takes
3669 location_t *, not location_t, so that the location can be
3670 adjusted. All uses changed.

3676 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
3677 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
3678 abort ();'. This reduces the runtime of the "Many lookaheads"

3690
3691 Remove nounput option. At an unexpected end of file, we now unput

3898 with quote slot used by complain_at.

3901 in symbols, long literals, and funny escapes in strings.

4007 The last OS that we could find where this wouldn't work is
4008 SunOS 3.5, and that's too old to worry about now.
4009

4384 Let nondeterministic skeletons be usable with deterministic
4385 tables.
4386
4387 With the patch, GAWK compiled by GCC without -O2 passes its test
4388 suite using a GLR parser driven by LALR tables. It fails with -O2
4389 because `struct stat' gives two different answers on my machine:
4390 88 (definition of an auto var) and later 96 (memset on this var).
4391 Hence the stack is badly corrumpted. The headers inclusion is to
4392 blame: if I move the awk.h inclusion before GLR's system header
4393 inclusion, the two struct stat have the same size.

4447 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,

4451 Use it to keep track of the rule length in the scanner, since
4452 we can't expect the parser to be in lock-step sync with the scanner.

4870 as int, and similarly for yyposn and YYINDEX.

4921 (_): New macro.
4922 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
4923 name locals "index", as it generates unnecessary warnings on some
4924 hosts that have an "index" function.

4965 to minimize the number of warnings from xgettext.
4966 (handle_action_dollar, handle_action_at): Don't use isdigit,
4967 as it mishandles negative chars and it may not work as expected
4968 outside the C locale.
4969
4970 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
4971 this is a GCC extension and is not portable to other compilers.

4974 Do not include <ctype.h>; no longer needed.
4975 Do not include <malloc.h>; no longer needed (and generates
4976 warnings on OpenBSD 3.0).
4977
4978 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
4979 it's not portable.
4980
4981 * tests/regression.at: Do not use 'cc -c input.c -o input';
4982 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
4983
4984 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
4985 exit status as failure, not just exit status 1. Sun C exits
4986 with status 2 sometimes.
4987

7484 Remove the support for C++ namespace cleanliness; it was
7485 causing more problems than it was curing, since it didn't work
7486 properly on some nonstandard C++ compilers. This can wait
7487 for a proper C++ parser.
7488
7489 * NEWS: Document this.
7490 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
7491 of C++, as it's treated like C now.
7492 * src/bison.simple (YYSTD): Remove.
7493 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
7494 Treat C++ just like Standard C instead of trying to support
7495 namespace cleanliness.

8167 these states are automatically computed from the initial state.
8168 (generate_states): Adjust.
8169 * src/print.c: When reporting a rule number to the user, substract
8170 1, so that the axiom rule is rule 0, and the first user rule is 1.
8171 * src/reduce.c: Likewise.
8172 * src/print_graph.c (print_core): For the time being, just as for

8206 Be sure to preserve the value of the eoftoken.
8207 (reader): Make sure eoftoken is defined.
8208 Initialize nsyms to 0: now eoftoken is created just like the others.
8209 * src/print.c (print_grammar): Don't special case the eof token.
8210 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
8211 lie anyway, albeit pleasant.
8212 * tests/calc.at: Exercise error messages with eoftoken.
8213 Change the grammar so that empty input is invalid.

9218 faster and reduces fragmentation.
9219
9220 Do not limit the number of items in the stack to a value that fits
9221 in 'int', as this is an arbitrary limit on hosts with 64-bit
9222 size_t and 32-bit int.

11450 The location tracking mechanism is precious for parse error

11486 Test also `--verbose', `--defines' and `--name-prefix'. Testing
11487 the latter demonstrates a flaw in the handling of non debugging
11488 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
11489 was used in order to simplify:
11490
11491 #if YYDEBUG

11500 if (yydebug)

11557 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
11558 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
11559 difficult and introduced a lot of core dump. It turns out that
11560 Bison used an implementation of `xmalloc' based on `calloc', and
11561 at various places it does depend upon the initialization to 0. I
11562 have not tried to isolate the pertinent places, and all the former
11563 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

12694 (lex): Use literalchar.
12695 (lex): Implemented "..." tokens.
12696 (literalchar, lex, parse_percent_token): Made tokenbuffer
12697 always contain the token. This includes growing the token
12698 buffer while reading an integer.
12699 (parse_percent_token): Replaced if-else statement with percent_table.
12700 (parse_percent_token): Added % declarations as another
12701 way to specify the flags -n, -l, and -r. Also added hooks for
12702 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
12703 major changes to files.c.
12704 (lex) Retain in the incoming stream a character following
12705 an incorrect '/'.
12706 (skip_white_space, lex): Revised most error messages
