16
17 deterministic test suite.
18 Some consistency checks on symbols are performed after all the
19 symbols were read, by an iteration over the symbol table. This
20 traversal is nondeterministic, which can be a problem for test
21 cases.
22 Avoid this.
23 Addresses another form of nondeterminism reported by Joel E. Denny.
24 http://lists.gnu.org/archive/html/bison-patches/2009-05/msg00023.html
25
26 * tests/input.at (Numbered tokens): Split the hexadecimal/decimal
27 test in two.
28 Use different file names for the three tests to make the
29 maintenance easier.

1441 There are two issues to handle: first scanning nested angle
1442 bracket pairs to support types such as std::pair< std::string,

1444
1445 Another issue is to address idiosyncracies of C++: do not glue two
1446 closing angle brackets together (otherwise it's operator>>), and
1447 avoid sticking blindly a TYPE to the opening <, as it can result
1448 in '<:' which is a digraph for '['.

1760 Finer input type for yytranslate.
1761 This patch is debatable: the tradition expects yylex to return an int
1762 which happens to correspond to token_number (which is an enum). This
1763 allows for instance to return characters (such as '*' etc.). But this
1764 goes against the stronger typing I am trying to have with the new
1765 lex interface which return a symbol_type. So in this case, feed
1766 yytranslate_ with a token_type.

1943 Introduce make_symbol.
b06df3c2
AD
1944 make_symbol provides a means to construct a full symbol (kind,
1945 value, location) in a single shot. It is meant to be a Symbol
1946 constructor, parameterized by the symbol kind so that overloading
1947 would prevent incorrect kind/value pairs. Unfortunately
1948 parameterized constructors do not work well in C++ (unless the
1949 parameter also appears as an argument, which is not acceptable),
1950 hence the use of a function instead of a constructor.

2165 Change the handling of the symbols in the skeletons.
2166 Before we were using tables which lines were the symbols and which
2167 columns were things like number, tag, type-name etc. It is was
2168 difficult to extend: each time a column was added, all the numbers had
2169 to be updated (you asked for colon $2, not for "tag"). Also, it was
2170 hard to filter these tables when only a subset of the symbols (say the
2171 tokens, or the nterms, or the tokens that have and external number
2172 *and* a type-name) was of interest.
de62edee 2173
d69c9694

2174 Now instead of monolithic tables, we define one macro per cell. For
2175 instance "b4_symbol(0, tag)" is a macro name which contents is
2176 self-decriptive. The macro "b4_symbol" provides easier access to
2177 these cells.

2500 Unfortunately this uncovered a bug in the C++ parser itself: the
2501 lookahead value was not destroyed between two calls to yylex. For
2502 instance if the previous lookahead was a std::string, and then an int,
2503 then the value of the std::string was correctly taken (i.e., the
2504 lookahead was now an empty string), but std::string structure itself
2505 was not reclaimed.
de62edee 2506

2507 This is now done in variant::build(other&) (which is used to take the
2508 value of the lookahead): other is not only stolen from its value, it
2509 is also destroyed. This incurs a new performance penalty of a few

2791 Fuse the three stacks into a single one.
de62edee 2792
b06df3c2
AD
2793 In order to make it easy to perform benchmarks to ensure that
2794 there are no performance loss, lalr1.cc is forked into
2795 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
2796 lalr1.cc.
2797
2798 Meanwhile, to make sure that lalr1-fusion.cc is correctly
2799 exercized by the test suite, the user must install a symbolic link
2800 from lalr1.cc to it.
de62edee 2801
b06df3c2

2802 Instead of having three stacks (state, value, location), use a
2803 stack of triples. This considerably simplifies the code (and it
2804 will be easier not to require locations as currently does the C++
2805 parser), and also gives a 10% speedup according to
2806 etc/bench (probably mainly since memory allocation is done once
2807 instead of three times).
de62edee 2808
0e0ed236

2809 Another motivation is to make it easier to destruct properly
2810 semantic values: now that they are bound to their state (hence
2811 symbol type) it will be easier to call the appropriate destructor.

2858 Use variants to support objects as semantic values.
b06df3c2
AD
2859 This patch was inspired by work by Michiel De Wilde. But he used
2860 Boost variants which (i) requires Boost on the user side, (ii) is
2861 slow, and (iii) has useless overhead (the parser knows the type of
2862 the semantic value there is no reason to duplicate this
2863 information as Boost.Variants do).
2864
2865 This implementation reserves a buffer large enough to store the
2866 largest objects. yy::variant implements this buffer. It was
2867 implemented with Quentin Hocquet.

3422 Update to the current gnulib CVS repository, and fix trigraph handling
3423 in Bison.
3424 * bootstrap: Update gnulib CVS repository URL.
3425 (symlink_to_dir): Encapsulate the code that guarantees the destination
3426 directory exists into...
3427 (check_dst_dir): ... this new function, and...
3428 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
3429 fail when copying files into lib/uniwidth/.
3430 * src/output.c (prepare_symbols): When writing yytname muscles, where
3431 symbol names will be encoded in C-string literals, tell quotearg to
3432 escape trigraphs. This used to be the default in gnulib.
3433 * tests/regression.at (Token definitions): Because of the change in
3434 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
3435 escapes trigraphs in symbol names. Thus, yytname no longer has
3436 trigraphs unnecessarily doubly escaped. Update test case output.
3437 Extend test case to be sure Bison's own error messages will no longer
3438 have trigraphs in symbol names unnecessarily escaped once.

4564 * src/lalr.c (state_lookahead_tokens_count): For code readability,
4565 move the check for disabled transitions to an aver since conflict
4566 resolution hasn't happened yet.
4567
4568 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
4569 labels a state as inconsistent just because it has error transitions.
4570 The original form of this check appeared in revision 1.1 of lalr.c,
4571 which was committed on 1991-12-21. Now (at least), changing the
4572 consistency label on such a state appears to have no useful effect in
4573 any of the places it is examined, which I enumerate below. The key
4574 point to understanding each item in this enumeration is that a state
4575 with an error transition is labelled consistent in the first place only
4576 if it has no rules, so the check cannot matter for states that have
4577 rules. (1) Labelling a state as inconsistent will cause set_conflicts
4578 to try to identify its conflicts, and a state must have *rules* to have
4579 conflicts. (2) Labelling a state as inconsistent will affect how
4580 action_row sets the default *rule* for the state. (3) Labelling a
4581 state as inconsistent will cause build_relations to add lookback edges
4582 to *rules* in that state.
4583 * src/state.h (struct state): Word the comment for member consistent
4584 more carefully.

5086 %define variable names and %code qualifiers.

5091 (b4_percent_define_get, b4_percent_code_get): ... these.
5092 Extend documentation with examples.
5093 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use

5095 b4_percent_code_skeleton_qualifiers.
5096 Expect any value for the %define variable `foo' to be stored in the

5098 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
5099 expect any unqualified %code blocks to be stored in a macro named
5100 `b4_percent_code_unqualified'.
5101 Use m4_indir so that %define variable names and %code qualifiers can
5102 contain `.', which is allowed by the grammar parser.
5103 (b4_percent_define_default): New macro to set a default value for a
5104 %define variable.
5105 (m4_wrap): Update wrapped code, and fix some underquoting.

5222 Instead of having skeletons declare all valid %define variables and

5225 variable or qualifier is not used by the skeleton in the current
5226 invocation regardless of whether it might sometimes be used by that
5227 skeleton in other invocations. Also, move all %define value macros to
5228 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
5229 form, which is replaced by %code.
5230 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...

5234 Warn instead of complaining.
5235 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define

5556 and printers.
5557 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.

5685 prototype yylex in the module that calls yyparse, and don't prototype

5691 Enable push parsers to operate in impure mode. Thus, %push-parser no
5692 longer implies %pure-parser. The point of this change is to move
5693 towards being able to test the push parser code by running the entire
5694 test suite as if %push-parser had been declared.
5695 * data/push.c (yypush_parse): For impure mode, remove the
5696 yypushed_char, yypushed_val, and yypushed_loc arguments.
5697 Instead, declare these as local variables initialized to the global
5698 yychar, yylval, and yylloc.
5699 For the first yypush_parse invocation only, restore the initial values
5700 of these global variables when it's time to read a token since they
5701 have been overwritten.
5702 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
5703 %push-parser.
5704 * tests/calc.at (Simple LALR(1) Calculator): Always declare
5705 %pure-parser along with %push-parser since this test case was designed

5746 Rearrange initialization of the parser state variables so that the
5747 skeleton doesn't have to have a copy for pull mode and another for push
5748 mode. This patch also fixes at least a bug such that yylloc was not
5749 initialized (with b4_location_initial_line and
5750 b4_location_initial_column) upon calling yypush_parse. However, that
5751 initialization now overwrites the first token's location;
5752 %initial-action assigning @$ already did the same thing, and both bugs
5753 will be fixed in a later patch.
5754 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.

5758 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and

5760 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to

5762 (yyparse or yypush_parse): For yypush_parse, don't print the
5763 "Starting parse" diagnostic for invocations after the first.
5764 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
5765 yypush_parse, only do it for the first invocation.

6854 Whether the default %destructor/%printer applies to a particular symbol
6855 isn't a question of whether the user *declares* that symbol (in %token,
6856 for example). It's a question of whether the user by any means
6857 *defines* the symbol at all (by simply using a char token, for
6858 example). $end is defined by Bison whereas any other token with token
6859 number 0 is defined by the user. The error token is always defined by
6860 Bison regardless of whether the user declares it with %token, but we
6861 may one day let the user define error as a nonterminal instead.
6862 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
6863 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document

7262 no longer copies it.
7263 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,

7265 by mbswidth) needs the latter.
7266 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to

7377 rule.

7380 warnings about types for $$, $n, @$, and @n can't be reported yet.
7381 (packgram): Translate the action and invoke grammar_rule_check now that
7382 all symbol declarations have been parsed.
7383 * src/scan-code.l (handle_action_dollar): Now that this is invoked
7384 after parsing the entire grammar file, the symbol list here in the case
7385 of a midrule is actually the midrule's empty RHS, so reference its
7386 parent rule's RHS where necessary.
7387 On the other hand, now that you can already know it's a midrule, you

7595 The Translation Project changed its way of publishing translations
7596 to maintainers. I haven't received any responses to my request
7597 for supporting the old way, or for documenting the new way. I
7598 have modified 'bootstrap' to use screen scraping
7599 (in this case, HTML scraping). This is unreliable and inelegant,
7600 but I don't see any better way. Yuck.
7601 * bootstrap (TP_URL, WGET_COMMAND): New vars.
7602 (get_translations): New function, which uses HTML scraping to
7603 deduce locations of latest translations.
7604 Use this function to grab both bison and bison-runtime .po files.
7605 Don't bother priming the pump for the runtime-po domain any more,
7606 as it's now translated better than bison is.

8375 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
8376 got from <http://bro-ids.org/download.html>. The bug is that
8377 when two actions appeared in succession, the second one was
8378 scanned before the first one was added to the grammar rule
8379 as a midrule action. Bison then output the incorrect warning
8380 "parse.y:905.17-906.36: warning: unused value: $3".
8381 * src/parse-gram.y (BRACED_CODE, action): These are no longer
8382 associated with a value.
8383 (rhs): Don't invoke grammar_current_rule_action_append.

8385 * src/reader.c (grammar_midrule_action): Now extern.

8387 grammar_midrule_action; that is now the scanner's job.

9607 Instead, reallocate buffers twice as big each time, so that

9980 the new runtime-po domain, prime the pump by extracting the
9981 relevant strings from the obsolete translations. This code can be
9982 removed once the bison-runtime domain has been translated by each
9983 team.

10012 the 2005-04-17 change, which is now accomplished (mostly) via
10013 changes in the parsers as described above.

10020 * tests/cxx-type.at: Don't pipe output of ./types through sed to
10021 remove trailing spaces. This loses the exit status of ./types,
10022 and isn't needed since ./types shouldn't be emitting trailing
10023 spaces.
10024 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
10025 as the stack isn't valid in that case.

10039
10040 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
10041 to FILE * parameter, not to stderr. This fixes a typo introduced
10042 in the 2005-07-12 change.

10056 Destructor cleanups and regularization among the three skeletons.

10059 stack before failing, as the cleanup code will do it for us now.

10062 freeing it, so that destructors get called properly.
10063 * data/lalr1.cc (yyreturn): Likewise.
10064 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
10065 This is more consistent.
10066 * doc/bison.texinfo (Destructor Decl): Mention more reasons
10067 why destructors might be called. 1.875 -> 2.1.
10068 (Destructor Decl, Decl Summary, Table of Symbols):
10069 Some English-language cleanups for %destructor.
10070 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10071 Add output line for destructor of start symbol.

10082 Rename yyoverflowab to yyexhaustedlab.
10083 When memory exhaustion occurs during syntax-error reporting,
10084 report it separately rather than in a single diagnostic; this
10085 eases translation.

10095 msgids; there's little point to having them translated, since they
10096 can be understood only by someone who can read the
10097 (English-language) source code.
10098
10099 Generate runtime-po/bison-runtime.pot automatically, so that we
10100 don't have to worry about garbage getting in that file. We'll
10101 make sure after the next official release that old msgids don't
10102 get lost. See
10103 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
10104
10105 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
10106 Now auto-generated.
10107 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
10108 Fix typos in explanations of the runtime file.
10109 * bootstrap: Change gettext keyword from YYI18N to YY_.
10110 Use standard Makefile.in.in in runtime-po, since we'll arrange
10111 for backward-compatible bison-runtime.po files in a different way.
10112 * data/glr.c (YY_): New macro, from yacc.c.
10113 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
10114 Translate messages intended for users.
10115 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
10116 the wording in the other skeletons. We don't know that the memory
10117 is virtual.
10118 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
10119 Use same method that yacc.c uses.
10120 Don't translate debugging messages.
10121 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
10122 it doesn't work (yet), and requires C++ expertise to fix.
10123 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
10124 Move defn to a more logical place, to be consistent with other
10125 skeletons.
10126 Don't translate debugging messages.
10127 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
10128 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
10129 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
10130 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

10144 (yyStackOverflow): Just longjmp, but with value 2 so that caller
10145 can handle the problem.
10146 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
10147 (yyparse): New local variable yyresult to record the result.

10149 struct.
10150 (yyDone): Remove label.
10151 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
10152 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
10153 if YYABORT is used).
10154 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
10155 yyparse status; put status > 1 into diagnostic.
10156 Check that status==2 works.

10305 * data/yacc.c (yyparse): In the initial action, set
10306 yylsp[0] and yyvsp[0] rather than yylloc and yylval.

10308 action does not set yylloc and/or yylval.

10316 not GNU M4, and that it works with any POSIX-compatible Awk.

10318 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
10319 so that we also get calc++-parser.yy. Geneate it.
10320 Use $(AWK), not gawk, since any conforming Awk will do.
10321 Put comment before action, since older 'make' can't handle comment
10322 in action.

10327 of target. (This had a shell syntax error anyway; a stray "x".)

10360 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
10361 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
10362 so that we don't have to maintain their signatures.

10364 than vsprintf. Allocate a bigger buffer if possible.
10365 Report an error if buffer allocation fails.
10366 (yyStackOverflow): New function.
10367 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
10368 the initialization was successful. It might fail if storage was
10369 exhausted.

10377 can print diagnostics on storage allocation failure. All callers
10378 changed.
10379 (yyresolveValue): Use yybool for boolean.
10380 (yyreportSyntaxError): Check for size-calculation overflow.
10381 This code is taken from yacc.c.

11025 Fix some problems reported by twlevo at xs4all.
11026 * src/symtab.c (symbol_new): Report an error if the input grammar
11027 contains too many symbols. This is better than calling abort() later.
11028 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.

11060 pseudo namespace.
11061 Adjust uses.
11062 (b4_parse_param_decl): Remove the leading comma as it is now only
11063 called as unique argument list.

11065 an initial debugging level.

11094 first one uniformly. Problem reported by Frank Heckenbach.
11095 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
11096 use exactly the same macro in both places.
11097 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
11098 so that the normal-case YYRHSLOC works for the error case too.

11103 we have an array of locations. Use the same macro for both glr
11104 and lalr parsers. Mention YYRHSLOC. Mention what happens when

11122 merely a doc fix, since the two types are equivalent).

11142 unless otherwise specified below.
11143
11144 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
11145 to allocate kernel_base, kernel_items, kernel_size, since

11169 for initial core. Just have a separate core, so we needn't worry
11170 about whether kernel_size and kernel_base are initialized.
11171

11181
11182 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
11183 This is because all callers pass unsigned int.
11184 * src/closure.h (new_closure): Likewise.
11185
11186 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
11187 (build_relations): Initialize includes[i] in all cases.
11188 * src/reader.c (packgram): Always initialize rules[ruleno].prec
11189 and rules[ruleno].precsym. Initialize members in order.

11191 and end_R[i].
11192 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
11193
11194 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
11195 conflict_list[0] was always 0, but now it isn't initialized.
11196
11197 * src/table.c (table_grow): When conflict_table grew, the grown
11198 area wasn't cleared. Fix this.
11199

11208 ngotos + 1 without checking for overflow.
11209 (build_relations): Use END_NODE, not -1, to denote end of edges.
11210 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,

11334 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
11335 whether the reducion was empty or not. This leaves room to
11336 improve the use of YYLLOC_DEFAULT in such a case.
11337 lalr1.cc is still experimental, so changing this is acceptable.
11338 And finally, there are probably not many users who changed the
11339 handling of locations in GLR, so changing is admissible too.

11484 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
11485 Bison directive from the Bison file to the invocation of this
11486 macro, so that these directives are passed to
11487 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
11488 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
11489 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
11490 the extra Bison directives instead of the whole series.
11491 Change the grammar so that there are recoverable errors, and
11492 unrecoverable errors. Now we can have the parser give up before
11493 consuming the whole input. As a result we now can observe that
11494 the lookahead is freed when needed.
11495 Change the parser source to parse argv[1] instead of a hard coded
11496 string.
11497 Simplify yylex, and give a value and location to EOF.
11498 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
11499 passed directives already coded in the file.
11500 Add some tests to check the location of "error".
11501 For some tests, the C++ parser is correct, and not yacc.c.
11502 For other tests, they provide different, but unsatisfying, values,
11503 so keep the C++ value so that at least one parser is "correct"
11504 according to the test suite.
11505 (Actions after errors): Remove, this is subsumed by the
11506 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

12079 There's no need to mention top_builddir since Automake does that
12080 for us.

12206 When reducing initial empty rules, Bison parser read an initial
12207 location that is not defined. This results in garbage, and that
12208 affects Bison's own parser. Therefore we need (i) to extend Bison

12503 Fix a GLR parser bug I reported in February; see

12505 The problem was that GLR parsers did not conform to the C standard,
12506 because actions like { $1 = $2 + $3; } expanded to expressions
12507 that invoked YYFILL in separate subexpressions, and YYFILL assigned
12508 to a local variable. The C standard says that expressions
12509 like (var = f ()) + (var = f ()) have undefined behavior.
12510 Another problem was that GCC sometimes issues warnings that
12511 yyfill and its parameters are unused.
12512
12513 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
12514 as possibly unused.
12515 (yyfill): New function.
12516 (YYFILL): Use it.
12517 (yyuserAction): Change type of yynormal to bool, so that it matches
12518 the new yyfill signature. Mark it as possibly unused.

12521 Follow up on a bug I reported in February, where a Bison-generated
12522 parser can loop. Provide a test case and a fix for yacc.c. I
12523 don't have a fix for lalr1.cc or for glr.c, unfortunately.
12524 The original bug report is in:

12527 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
12528 macro's size was becoming unwieldy.
12529 (yyerrlab): Do not discard an empty lookahead symbol, as this
12530 might destroy garbage.
12531 (yyerrorlab): New label, with the old contents of YYERROR,
12532 plus the following change: pop the stack of rhs corresponding
12533 to the production that invoked YYERROR. That is how Yacc
12534 behaves, and POSIX requires this behavior.
12535 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
12536 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
12537 Define 'alarm' to do nothing if unistd.h is not available.
12538 Add a new rule "exp: '-' error;" to test the above change to
12539 data/yacc.c. Use 'alarm' to abort any test taking longer than
12540 10 seconds, as it's probably looping.
12541 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
12542 Also, the new yacc.c generates two fewer diagnostics for an
12543 existing test.

13190 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
13191 when the stacks contain one element, as the loop would otherwise
13192 free the last state, and then use the top state (the one we just
13193 popped). This means that the initial elements will not be freed
13194 explicitly, as is the case in yacc.c; it is not a problem, as
13195 these elements have fake values.

13303 of the 2002-07-30 change.
13304 * doc/bison.texinfo (Understanding): Use Yacc style for
13305 conflict reports. Also, use new way of locating rules.
13306 * src/conflicts.c (conflict_report):
13307 Renamed from conflict_report_yacc, removing the old
13308 'conflict_report'. Translate the entire conflict report at once,
13309 so that we don't assume that "," has the same interpretation in
13310 all languages.
13311 (conflicts_output): Use Yacc-style conflict report for each state,
13312 instead of our more-complicated style.
13313 (conflicts_print): Use Yacc-style conflict report, except print
13314 the input file name when not emulating Yacc.
13315 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
13316 Conflicted Reduction, %expect not enough, %expect too much,
13317 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
13318 * tests/existing.at (GNU Cim Grammar): Likewise.

13320

13328 Fix a bug where error locations were not being recorded correctly.
13329 This problem was originally reported by Paul Hilfinger in

13331
13332 * data/yacc.c (yyparse): New local var yylerrsp, to record the
13333 top of the location stack's error locations.
13334 (yyerrlab): Set it. When discarding a token, push its location
13335 onto yylerrsp so that we don't lose track of the error's end.
13336 (yyerrlab1): Now is only the target of YYERROR, so that we can
13337 properly record the location of the action that failed. For GCC
13338 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
13339 GCC warning about yyerrlab1 being unused if YYERROR is unused.
13340 (yyerrlab2): New label, which yyerrlab now falls through to.
13341 Compute the error's location by applying YYLLOC_DEFAULT to
13342 the locations of all the symbols that went into the error.
13343 * doc/bison.texinfo (Location Default Action): Mention that
13344 YYLLOC_DEFAULT is also invoked for syntax errors.
13345 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
13346 Error locations include the locations of all the tokens that were
13347 discarded, not just the last token.

13404 If the user does not define YYSTYPE as a macro, Bison now declares it
13405 using typedef instead of defining it as a macro. POSIX requires this.
13406 For consistency, YYLTYPE is also declared instead of defined.
13407
13408 %union directives can now have a tag before the `{', e.g., the
13409 directive `%union foo {...}' now generates the C code
13410 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
13411 The default union tag is `YYSTYPE', for compatibility with Solaris 9
13412 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
13413 instead of `yyltype'.
13414
13415 `yystype' and `yyltype' are now obsolescent macros instead of being
13416 typedefs or tags; they are no longer documented and will be
13417 withdrawn in a future release.

13423 (YYLTYPE): Renamed from yyltype.
13424 (yyltype, yystype): New (and obsolescent) macros,
13425 for backward compatibility.
13426 * data/yacc.c: Likewise.
13427
13428 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
13429 does not specify a union tag. This is for compatibility with
13430 Solaris 9 yacc.
13431
13432 * src/parse-gram.y (add_param): 2nd arg is now char * not char

13451 to return when scanning braced code.

13781 then the . include files in double-quotes (alphabetized). Fix
13782 dependency breakages encountered in this process, as follows:

13850 processing of Yacc white space and equivalents here.

13852 instead of returning ID immediately, since we need to search for
13853 a subsequent colon.
13854 (<INITIAL>"'", "\""): Save token_start.
13855 (<INITIAL>"%{", "{", "%%"): Save code_start.
13856 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.

13949 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
13950 The name "yycontrol" violates the name space rules, and this stuff
13951 wasn't being used anyway.

13994 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
13995 should use `if (! x) abort ();' rather than `assert (x);', and
13996 anyway it's one less thing to worry about configuring.

14053 to "SyntaxError" for consistency with my 2002-11-15 change.
14054
14055 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
14056 not define to {}, since this breaks the common use of `YYDPRINTF
14057 ((...));' if a single statement is desired (e.g. before `else').
14058 Work around GCC warnings by surrounding corresponding calls with
14059 {} if needed.
14060 (yyhasResolvedValue): Remove unused function.

14410 Use new @ escapes consistently. Represent brackets with @{ and @}
14411 rather than @<:@ and @:>@, since this works a bit better with dumb
14412 editors like vi. Represent @ with @@, since @ is now consistently
14413 an escape. Use @oline@ and @ofile@ rather than __oline__ and
14414 __ofile__, to avoid unexpected expansions. Similarly, use @output
14415 rather than #output.
14416
14417 * data/c.m4 (b4_copyright): Omit file name from comment, since
14418 the file name could contain "*/".

14465 them with auto vars.
14466 Switch to new escape scheme, where @ is the escape character uniformly.
14467 Abort if a stray escape character is found. Avoid unbounded input
14468 buffer when parsing non-escaped text.

14480 (yygetLRActions, yyrecoverParseError): Use them.

14483 counted in the token inserted at end of file. Now takes
14484 location_t *, not location_t, so that the location can be
14485 adjusted. All uses changed.

15064 Stop using the "enum_" trick for K&R-style function definitions;
15065 it confused me, and I was the author! Instead, assume that people

15199 Let nondeterministic skeletons be usable with deterministic
15200 tables.
15201
15202 With the patch, GAWK compiled by GCC without -O2 passes its test
15203 suite using a GLR parser driven by LALR tables. It fails with -O2
15204 because `struct stat' gives two different answers on my machine:
15205 88 (definition of an auto var) and later 96 (memset on this var).
15206 Hence the stack is badly corrumpted. The headers inclusion is to
15207 blame: if I move the awk.h inclusion before GLR's system header
15208 inclusion, the two struct stat have the same size.

15262 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,

15764 lib/timevar.c.

17749 (Even though this 2 is not the same as above: the number of the
17750 undeftoken remains being 2, it is its user token number which

18514 a conflict with the macro from lib/hash.h).

18613 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
18614 The ISO C++ standard is extremely clear about it: stderr is
18615 considered a macro, not a regular symbol (see table 94 `Header
18616 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
18617 Therefore std:: does not apply to it. It still does with fprintf.

18631 renaming.
18632 (%union): Having several members with the same type does not help
18633 type mismatches, simplify.

18651 Throw away MS-DOS crap: we don't need getpid.
18652 * configure.in: We don't need strndup. It was even causing
18653 problems: because Flex includes the headers *before* us,
18654 _GNU_SOURCE is not defined by config.h, and therefore strndup was
18655 not visible.
18656 * lib/xstrndup.c: New.
18657 * src/scan-skel.l: Use it.
18658 Be sure to initialize yylval.muscle member when scanning a MUSCLE.

18670 (process_skeleton): Returns void, and takes a single parameter.
18671 * src/scan-skel.l: Add the license notice.
18672 Include skeleton.h.
18673 Don't use %option yylineno: it seems that then Flex imagines
18674 REJECT has been used, and therefore it won't reallocate its
18675 buffers (which makes no other sense to me than a bug). It results
18676 in warnings for `unused: yy_flex_realloc'.

18899 * src/LR0.c (final_state): Initialize to -1 so that we do compute
18900 the reductions of the first state which was mistakenly confused
18901 with the final state because precisely final_state was initialized

18954 Sparc, as they were causing more porting problems than the

18981 (insert_accepting_state, augment_automaton): Remove, since now
18982 these states are automatically computed from the initial state.
18983 (generate_states): Adjust.
18984 * src/print.c: When reporting a rule number to the user, substract
18985 1, so that the axiom rule is rule 0, and the first user rule is 1.
18986 * src/reduce.c: Likewise.
18987 * src/print_graph.c (print_core): For the time being, just as for
18988 the report, depend upon --trace-flags to dump the full set of
18989 items.
18990 * src/reader.c (readgram): Once the grammar read, insert the rule
18991 0: `$axiom: START-SYMBOL $'.
18992 * tests/set.at: Adjust: rule 0 is now displayed, and since the
18993 number of the states has changed (the final state is no longer
18994 necessarily the last), catch up.

18999 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
19000 is used instead of > 0 where appropriate, (ii), depend upon nritems
19001 instead of the 0-sentinel.

19017 * src/reader.c (eoftoken): New.
19018 (parse_token_decl): If the token being defined has value `0', it
19019 is the eoftoken.
19020 (packsymbols): No longer hack `tags' to insert `$' by hand.
19021 Be sure to preserve the value of the eoftoken.
19022 (reader): Make sure eoftoken is defined.
19023 Initialize nsyms to 0: now eoftoken is created just like the others.
19024 * src/print.c (print_grammar): Don't special case the eof token.
19025 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
19026 lie anyway, albeit pleasant.
19027 * tests/calc.at: Exercise error messages with eoftoken.
19028 Change the grammar so that empty input is invalid.
19029 Adjust expectations.

19121 Don't parse the user action that might follow the guard, let...

19168 `lookaheadsp' member of the following state (since lookaheads of

19869 Because useless nonterminals are now kept alive (instead of being
19870 `destroyed'), we now sometimes examine them, and store information
19871 related to them. Hence we need to know their number, and adjust
19872 memory allocations.

19874 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
19875 static.
19876 * src/LR0.c (allocate_itemsets): The memory allocated to
19877 `symbol_count' was used for two different purpose: once to count
19878 the number of occurrences of each symbol, and later reassigned to
19879 `shift_symbol', containing the symbol that can be shifted from a
19880 given state.
19881 Deobfuscate, i.e., allocate, use and free `symbol_count' here
19882 only, and...
19883 (new_itemsets): Allocate `shift_symbol' here.

20464 * tests/calc.at, tests/output.at, tests/regression.at,
20465 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
20466 now the tests are run in private dirs, therefore AC_CLEANUP and
20467 family can be simplified to 0-ary.
20468 * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
20469 use abs. path to find config.h.
20470 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
20471 stderr, there can be way too much random noise.
20472 Instead pass -Werror to GCC and rely on the exit status.

20492 braces to pacify GCC's warnings for `if () if () {} else {}'.
20493 * src/lex.c (parse_percent_token): Replace equal_offset with
20494 arg_offset.
20495 arg is const.
20496 Be sure to strdup `arg' when used, since there is no reason for
20497 token_buffer not to change.

22265 The location tracking mechanism is precious for parse error
22266 messages. Nevertheless, it is enabled only when `@n' is used in
22267 the grammar, which is a different issue (you can use it in error

22269 be another means to enable it.

22301 Test also `--verbose', `--defines' and `--name-prefix'. Testing
22302 the latter demonstrates a flaw in the handling of non debugging
22303 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
22304 was used in order to simplify:
22305
22306 #if YYDEBUG
22307 if (yydebug)
22308 {
22309 ...

22311 #endif

22313 into
22314
22315 if (yydebug)
22316 {
22317 ...
22318 }
22319
22320 unfortunately this leads to a CPP conflict when
22321 `--name-prefix=foo' is used since it produces `#define yydebug
22322 foodebug'.

22372 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
22373 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
22374 difficult and introduced a lot of core dump. It turns out that
22375 Bison used an implementation of `xmalloc' based on `calloc', and
22376 at various places it does depend upon the initialization to 0. I
22377 have not tried to isolate the pertinent places, and all the former
22378 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

23462 New function.
23463 (readgram): Use `#if 0' around code that accepted %command

23466 (parse_token_decl): Extended the %token
23467 declaration to allow a multi-character symbol as an alias.
23468 (parse_thong_decl): New function.

23479 Revised and use multiple warnxxx functions to avoid using VARARGS1.
23480 (read_declarations): Improve the error message for
23481 an invalid character. Do not abort.
23482 (read_declarations, copy_guard, copy_action): Use
23483 printable_version to avoid unprintable characters in printed output.

23509 (lex): Use literalchar.
23510 (lex): Implemented "..." tokens.
23511 (literalchar, lex, parse_percent_token): Made tokenbuffer
23512 always contain the token. This includes growing the token
23513 buffer while reading an integer.
23514 (parse_percent_token): Replaced if-else statement with percent_table.
23515 (parse_percent_token): Added % declarations as another
23516 way to specify the flags -n, -l, and -r. Also added hooks for
23517 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
23518 major changes to files.c.
23519 (lex) Retain in the incoming stream a character following
23520 an incorrect '/'.
23521 (skip_white_space, lex): Revised most error messages
