143 portability: fix several issues with M4 subprocess.
144
145 M4's output pipe was not being drained upon fatal errors during
146 scan_skel. As a result, broken-pipe messages from M4 were seen
147 on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
148 failure in the test suite. The problem was that, on platforms
149 where the default disposition for SIGPIPE is ignore instead of
150 terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
151 then reported it. However, there's some sort of race condition,
152 because the new test group occasionally succeeded.
153 Reported by Albert Chin at
154 <http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>.
155
156 There were also problems with the test suite livelocking on
157 Tru64 5.1b. Reported by Didier Godefroy at
158 <http://lists.gnu.org/archive/html/bug-bison/2009-05/msg00005.html>.
159 Switching to create_pipe_bidi suggested by Akim Demaille.
160
161 To attempt to solve both of these problems, switch to gnulib's
162 create_pipe_bidi and register M4 process as a slave. Along the
163 way, clean up file name conflict handling, which was affected by
164 the broken-pipe problem before the switch.
165 * NEWS (2.4.2): Document.
166 * THANKS (Didier Godefroy): Add.
167 * bootstrap.conf (gnulib_modules): Add pipe.
168 * gnulib: Update to latest to make sure we have all the latest

171 subpipe.c.

173 * src/files.c (compute_output_file_names): Update invocations
174 of output_file_name_check.
175 (output_file_name_check): In the case that the grammar file
176 would be overwritten, use complain instead of fatal, but replace
177 the output file name with /dev/null. Use the /dev/null solution
178 for the case of two conflicting output files as well because it
179 seems safer in case Bison one day tries to open both files at
180 the same time.
181 * src/files.h (output_file_name_check): Update prototype.

357 Fix handling of yychar manipulation in user semantic actions.
358 The problem was that yacc.c didn't always update the yychar
359 translation afterwards. However, other skeletons appear to be
360 fine. glr.c appears to already translate yychar before every
361 use. lalr1.cc does not define yychar and does not document its
362 replacement, yyla, for users. It does provide yyclearin, but
363 that does not manipulate yyla and thus requires no translation
364 update. In lalr1.java, yychar is out of scope during semantic
365 actions.
366 * NEWS (2.5): Document.
367 * data/yacc.c (YYBACKUP): Don't bother translating yychar into
368 yytoken here.
369 (yyparse, yypush_parse): Instead, translate before every use of
370 yytoken, and add comments explaining this approach.
371 * tests/actions.at (Destroying lookahead assigned by semantic
372 action): New test group checking that translation happens before
373 lookahead destructor calls at parser return. Previously,
374 incorrect destructors were called.
375 * tests/conflicts.at (%error-verbose and consistent
376 errors): New test group checking that translation happens at
377 syntax error detection before the associated verbose error
378 message and the associated lookahead destructor calls. While
379 the destructor call is fixed by this patch, the verbose error
380 message is currently incorrect due to another bug (see
381 comments in test group), so this is an expected failure for now.

560 yysyntax_error: avoid duplicate lookahead collection.
561 Except when memory reallocation is required, this change
562 eliminates the need to invoke yysyntax_error twice and thus to
563 repeat the collection of lookaheads. It also prepares for
564 future extensions that will make those repetitions more
565 expensive and that will require additional memory management in
566 yysyntax_error. Finally, it fixes an obscure bug already
567 exercised in the test suite.
568 * data/yacc.c (yysyntax_error): Add arguments for message
569 buffer variables stored in the parser. Instead of size, return

903 Fix complaints about escape sequences.
904 Discussed starting at
905 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>.
906 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
907 For a \0 and similar escape sequences meaning the null
908 character, report an invalid escape sequence instead of an
909 invalid null character because the latter does not actually
910 appear in the user's input.
911 In all escape sequence complaints, don't escape the initial
912 backslash, and don't quote when the sequence appears at the end
913 of the complaint line unless there's whitespace that quotearg
914 won't escape.
915 Consistently say "invalid" not "unrecognized".
916 Consistently prefer "empty character literal" over "extra
917 characters in character literal" warning for invalid escape
918 sequences; that is, consistently discard those sequences.
919 * tests/input.at (Bad escapes in literals): New.

3755 move the check for disabled transitions to an aver since conflict
3756 resolution hasn't happened yet.
3757
3758 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3759 labels a state as inconsistent just because it has error transitions.
3760 The original form of this check appeared in revision 1.1 of lalr.c,
3761 which was committed on 1991-12-21. Now (at least), changing the
3762 consistency label on such a state appears to have no useful effect in
3763 any of the places it is examined, which I enumerate below. The key
3764 point to understanding each item in this enumeration is that a state
3765 with an error transition is labelled consistent in the first place only
3766 if it has no rules, so the check cannot matter for states that have
3767 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3768 to try to identify its conflicts, and a state must have *rules* to have
3769 conflicts. (2) Labelling a state as inconsistent will affect how
3770 action_row sets the default *rule* for the state. (3) Labelling a
3771 state as inconsistent will cause build_relations to add lookback edges
3772 to *rules* in that state.
3773 * src/state.h (struct state): Word the comment for member consistent
3774 more carefully.

4080 * src/getargs.c: Revert 2007-02-03 change, as follows.
4081 Don't include c-strcase.h.
4082 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
4083 strcasecmp has "unspecified behavior" outside the POSIX locale,
4084 but it works fine in practice if at least one argument is ASCII,
4085 as is the case in Bison.

4283 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use

4412 Instead of having skeletons declare all valid %define variables and

4414 and build these lists automatically. Thus Bison will now warn when a
4415 variable or qualifier is not used by the skeleton in the current
4416 invocation regardless of whether it might sometimes be used by that
4417 skeleton in other invocations. Also, move all %define value macros to
4418 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
4419 form, which is replaced by %code.

4881 Enable push parsers to operate in impure mode. Thus, %push-parser no
4882 longer implies %pure-parser. The point of this change is to move
4883 towards being able to test the push parser code by running the entire
4884 test suite as if %push-parser had been declared.
4885 * data/push.c (yypush_parse): For impure mode, remove the
4886 yypushed_char, yypushed_val, and yypushed_loc arguments.
4887 Instead, declare these as local variables initialized to the global
4888 yychar, yylval, and yylloc.
4889 For the first yypush_parse invocation only, restore the initial values
4890 of these global variables when it's time to read a token since they
4891 have been overwritten.

4939 initialized (with b4_location_initial_line and
4940 b4_location_initial_column) upon calling yypush_parse. However, that
4941 initialization now overwrites the first token's location;
4942 %initial-action assigning @$ already did the same thing, and both bugs
4943 will be fixed in a later patch.

6047 Whether the default %destructor/%printer applies to a particular symbol
6048 isn't a question of whether the user *declares* that symbol (in %token,
6049 for example). It's a question of whether the user by any means
6050 *defines* the symbol at all (by simply using a char token, for
6051 example). $end is defined by Bison whereas any other token with token
6052 number 0 is defined by the user. The error token is always defined by
6053 Bison regardless of whether the user declares it with %token, but we
6054 may one day let the user define error as a nonterminal instead.
6055 * NEWS (2.3+): Say "user-defined" instead of "user-declared".

6354 The for-loop was introduced in the 2004-11-17 change but I don't
6355 know why it was needed.

6370 * NEWS: Instead of %union, you can define and use your own union type
6371 YYSTYPE if your grammar contains at least one <type> tag.
6372 Your YYSTYPE need not be a macro; it can be a typedef.
6373 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):

6381 Use 'union_seen' rather than 'typed' to determine whether
6382 %union has been seen, since grammars can now be typed without
6383 %union.
6384 (symbol_declaration, type.opt, symbol_def):

6396 for type tags without %union.

6399 int, since callers expect int. This may need to get revisited
6400 once we have proper integer overflow checking.

6403 object is now static.

6406 to pacify ./configure --enable-gcc-warnings.

6443 this was never guaranteed, and now that we're using gnulib stdint,
6444 which defines int_fast16_t to long int, the problem is exposed.

6454 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
6455 no longer copies it.
6456 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
6457 since stdint needs the former and wcwidth (which is now required
6458 by mbswidth) needs the latter.
6459 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
6460 work around a compatibility glitch between gettext 0.14.6 and
6461 Autoconf 2.60.
6462 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
6463 Do not check for uintptr_t, since new stdint module does the right
6464 thing.
6465 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.

6475 for ../lib/*.h files.
6476 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
6477 Define unconditionally, since we now assume the stdint module.
6478 * src/scan-skel.l: Include <dirname.h>.
6479 (BASE_QPUTS): Use last_component, not base_name.
6480 * src/system.h: Include <unlocked-io.h> in the usual order
6481 for ../lib/*.h files. Include <stdint.h> unconditionally,
6482 since we now use the stdint module.
6483 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
6484 HAVE_UINTPTR_T, since we now use the stdint module.
6485 (base_name): Remove decl, since files now include <dirname.h>
6486 to get the decl.

6567 Don't record whether the midrule's $$ has been used yet since actions
6568 haven't been translated yet.
6569 Record the midrule's parent rule and its RHS index within the parent
6570 rule.
6571 (grammar_current_rule_action_append): Don't translate the action yet
6572 since not all symbol declarations may have been parsed yet and, thus,
6573 warnings about types for $$, $n, @$, and @n can't be reported yet.
6574 (packgram): Translate the action and invoke grammar_rule_check now that
6575 all symbol declarations have been parsed.
6576 * src/scan-code.l (handle_action_dollar): Now that this is invoked
6577 after parsing the entire grammar file, the symbol list here in the case
6578 of a midrule is actually the midrule's empty RHS, so reference its
6579 parent rule's RHS where necessary.
6580 On the other hand, now that you can already know it's a midrule, you
6581 aren't forced to think $$ has the same type as its parent rule's $$.
6582 (handle_action_at): In the case of a midrule, reference the parent rule
6583 where necessary.
6584 * src/symlist.c (symbol_list_new): Initialize new midrule-related
6585 members.
6586 (symbol_list_length): Now that this is invoked after all rules have
6587 been parsed, a NULL symbol (rather than a NULL symbol list node)
6588 terminates a rule. symbol_list_print already does this correctly.
6589 * src/symlist.h (symbol_list.midrule_parent_rule,
6590 symbol_list.midrule_parent_rhs_index): New members so that midrules can
6591 remember their relationships with their parents.
6592 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
6593 fixed by the above patch.
6594 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
6595 implementing...

6788 The Translation Project changed its way of publishing translations

7128 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
7129 defined to be a type name without parens or brackets.
7130 (Location Type): Similarly for YYLTYPE.
7131 * tests/regression.at (Trivial grammars): Put in a test for this
7132 bug that will be caught by 'make maintainer-check' (though not,
7133 alas, by 'make check' unless your compiler is picky).

7142 * data/glr.c (yyreportTree): Make room in yystates for the state
7143 preceding the RHS. This fixes the segmentation fault reported by Derek
7144 M. Jones in

7146 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
7147 to the user. Reported for yyreportTree by Derek M. Jones later in the
7148 same thread.

7369 ambiguity.

7385 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
7386 * tests/glr-regression.at (Leaked semantic values when reporting
7387 ambiguity): New test case.
7388 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
7389 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
7390 now unnecessary yystackp parameter.
7391 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
7392 destructors can be called.
7393

7395 in existing testcases.

7399 Don't leak semantic values for parent RHS when a user action cuts the
7400 parser, and clean up related code a bit.

35ee866a
JD
7402 cuts parse): Rename to...
7403 (Leaked semantic values if user action cuts parse): ... this. Add check
520181ab
JD
7404 for leaked parent RHS values.
7405 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
7406 between an unresolved state (non-empty chain of semantic options) and
7407 an incomplete one (signaled by an empty chain).
ae952af2 7408 (yyresolveStates): Document the interface. Move all manipulation of a
520181ab
JD
7409 successfully or unsuccessfully resolved yyGLRState to...
7410 (yyresolveValue): ... here so that yyresolveValue always leaves a
7411 yyGLRState with consistent data and thus is easier to understand.
7412 Remove the yyvalp and yylocp parameters since they are always just
7413 taken from the yys parameter. When reporting a discarded merged value
7414 in debugging output, note that it is incompletely merged. Document the
7415 interface.
7416 (yyresolveAction): If resolving any of the RHS states fails, destroy
7417 them all rather than leaking them. Thus, as long as user actions are
7418 written to clean up the RHS correctly, yyresolveAction always cleans up
7419 the RHS of a semantic option. Document the interface.

7538 During deterministic GLR operation, user actions should be able to
7539 influence the parse by changing yychar. To make this easier to fix and
7540 to make glr.c easier to evolve in general, don't maintain yytoken in

7568 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
7569 got from <http://bro-ids.org/download.html>. The bug is that
7570 when two actions appeared in succession, the second one was
7571 scanned before the first one was added to the grammar rule
7572 as a midrule action. Bison then output the incorrect warning
7573 "parse.y:905.17-906.36: warning: unused value: $3".

7901
7902 * data/glr.c (yyresolveValue): When merging semantic options, if at
7903 least one user action succeeds but a later one cuts the parse, then
7904 destroy the semantic value before returning rather than leaking it.
7905 (yyresolveStates): If a user action cuts the parse and thus
7906 yyresolveValue fails, ignore the (unset) semantic value rather than
7907 corrupting the yyGLRState, and empty the semantic options list since
7908 the user actions should have called all necessary destructors.
7909 Simplify code with YYCHK.
7910 * tests/glr-regression.at (Corrupted semantic options if user action
7911 cuts parse): New test case.
7912 (Undesirable destructors if user action cuts parse): New test case.
7913 Before applying any of this patch, this test case never actually failed
7914 for me... but only because the corrupted semantic options usually
7915 masked this bug.
7916 (Leaked merged semantic value if user action cuts parse): New test
7917 case.

8800 Instead, reallocate buffers twice as big each time, so that
8801 we waste at most half the allocated memory. Start with a small

9175 removed once the bison-runtime domain has been translated by each

9213 * tests/cxx-type.at: Don't pipe output of ./types through sed to
9214 remove trailing spaces. This loses the exit status of ./types,
9215 and isn't needed since ./types shouldn't be emitting trailing
9216 spaces.
9217 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,

9253 * data/lalr1.cc (yyerrlab): Likewise.
9254 * data/glr.c (yyparse): Pop everything off the stack before
9255 freeing it, so that destructors get called properly.

9278 eases translation.

9289 can be understood only by someone who can read the
9290 (English-language) source code.
9291
9292 Generate runtime-po/bison-runtime.pot automatically, so that we
9293 don't have to worry about garbage getting in that file. We'll
9294 make sure after the next official release that old msgids don't

9301 Fix typos in explanations of the runtime file.
9302 * bootstrap: Change gettext keyword from YYI18N to YY_.
9303 Use standard Makefile.in.in in runtime-po, since we'll arrange
9304 for backward-compatible bison-runtime.po files in a different way.
9305 * data/glr.c (YY_): New macro, from yacc.c.
9306 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
9307 Translate messages intended for users.
9308 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
9309 the wording in the other skeletons. We don't know that the memory
9310 is virtual.
9311 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
9312 Use same method that yacc.c uses.
9313 Don't translate debugging messages.
9314 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
9315 it doesn't work (yet), and requires C++ expertise to fix.
9316 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
9317 Move defn to a more logical place, to be consistent with other
9318 skeletons.
9319 Don't translate debugging messages.
9320 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
9321 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
9322 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
9323 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

9557 than vsprintf. Allocate a bigger buffer if possible.

9561 the initialization was successful. It might fail if storage was
9562 exhausted.

10527 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
10528 whether the reducion was empty or not. This leaves room to
10529 improve the use of YYLLOC_DEFAULT in such a case.
10530 lalr1.cc is still experimental, so changing this is acceptable.
10531 And finally, there are probably not many users who changed the

10593 Let the initial-action act on the look-ahead, and use it for the
10594 "initial push" (corresponding to an hypothetical beginning-of-file).
10595 And let lalr1.cc honor %initial-action.
10596
10597 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an

10599 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
10600 (Parser::Parser): Remove the ctor that used to initialize it.
10601 (Parser::parse): Like in the other skeletons, issue the "starting
10602 parse" message before any action.
10603 Honor %initial-action.
10604 Initialize the stacks with the lookahead.
10605 * data/yacc.c: Let $$ and @$ in %initial-action designate the
10606 look-ahead.
10607 Push them in the stacks.

10632 value of the result.

10635 This allows to replace code relying on the implementation of
10636 locations by portable code.
10637 * data/yacc.c (yylerrsp): Replace with...

10640 accurate location for the error token.

10666 including for the error token.
10667 * data/lalr1.cc (symprint_): Output the location.
10668 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
10669 output the location within the %printer.
10670 Activate GLR tests, at least to make sure they compile properly.
10671 They still don't pass though.
10672 * tests/calc.at: Adjust expect verbose output, since now "Entering
10673 state..." is on a different line than the "Shifting" message.

10677 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
10678 Bison directive from the Bison file to the invocation of this
10679 macro, so that these directives are passed to
10680 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
10681 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
10682 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10683 the extra Bison directives instead of the whole series.
10684 Change the grammar so that there are recoverable errors, and
10685 unrecoverable errors. Now we can have the parser give up before
10686 consuming the whole input. As a result we now can observe that
10687 the lookahead is freed when needed.
10688 Change the parser source to parse argv[1] instead of a hard coded
10689 string.
10690 Simplify yylex, and give a value and location to EOF.
10691 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10692 passed directives already coded in the file.
10693 Add some tests to check the location of "error".
10694 For some tests, the C++ parser is correct, and not yacc.c.
10695 For other tests, they provide different, but unsatisfying, values,
10696 so keep the C++ value so that at least one parser is "correct"
10697 according to the test suite.
10698 (Actions after errors): Remove, this is subsumed by the
10699 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

10877 Spent a few hours checking out which prerequisite versions the

10880 a seemingly endless set of combinations of versions more recent
10881 than that. The bottom line is that the current sources require
10882 fairly recent versions of the build tools, and it'll be some work

11272 There's no need to mention top_builddir since Automake does that
11273 for us.

11399 When reducing initial empty rules, Bison parser read an initial
11400 location that is not defined. This results in garbage, and that
11401 affects Bison's own parser. Therefore we need (i) to extend Bison

11403 this CVS Bison to fix CVS Bison's parser.

11696 Fix a GLR parser bug I reported in February; see

11698 The problem was that GLR parsers did not conform to the C standard,
11699 because actions like { $1 = $2 + $3; } expanded to expressions
11700 that invoked YYFILL in separate subexpressions, and YYFILL assigned
11701 to a local variable. The C standard says that expressions
11702 like (var = f ()) + (var = f ()) have undefined behavior.
11703 Another problem was that GCC sometimes issues warnings that
11704 yyfill and its parameters are unused.
11705
11706 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
11707 as possibly unused.
11708 (yyfill): New function.
11709 (YYFILL): Use it.
11710 (yyuserAction): Change type of yynormal to bool, so that it matches
11711 the new yyfill signature. Mark it as possibly unused.
11712
11713
11714 Follow up on a bug I reported in February, where a Bison-generated
11715 parser can loop. Provide a test case and a fix for yacc.c. I
11716 don't have a fix for lalr1.cc or for glr.c, unfortunately.
11717 The original bug report is in:

11720 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
11721 macro's size was becoming unwieldy.
11722 (yyerrlab): Do not discard an empty lookahead symbol, as this
11723 might destroy garbage.
11724 (yyerrorlab): New label, with the old contents of YYERROR,
11725 plus the following change: pop the stack of rhs corresponding
11726 to the production that invoked YYERROR. That is how Yacc
11727 behaves, and POSIX requires this behavior.
11728 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
11729 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
11730 Define 'alarm' to do nothing if unistd.h is not available.
11731 Add a new rule "exp: '-' error;" to test the above change to
11732 data/yacc.c. Use 'alarm' to abort any test taking longer than
11733 10 seconds, as it's probably looping.
11734 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11735 Also, the new yacc.c generates two fewer diagnostics for an
11736 existing test.

12383 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
12384 when the stacks contain one element, as the loop would otherwise
12385 free the last state, and then use the top state (the one we just
12386 popped). This means that the initial elements will not be freed
12387 explicitly, as is the case in yacc.c; it is not a problem, as
12388 these elements have fake values.

12501 'conflict_report'. Translate the entire conflict report at once,
12502 so that we don't assume that "," has the same interpretation in

12504 (conflicts_output): Use Yacc-style conflict report for each state,
12505 instead of our more-complicated style.

12522 This problem was originally reported by Paul Hilfinger in

12525 * data/yacc.c (yyparse): New local var yylerrsp, to record the
12526 top of the location stack's error locations.
12527 (yyerrlab): Set it. When discarding a token, push its location
12528 onto yylerrsp so that we don't lose track of the error's end.
12529 (yyerrlab1): Now is only the target of YYERROR, so that we can
12530 properly record the location of the action that failed. For GCC
12531 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
12532 GCC warning about yyerrlab1 being unused if YYERROR is unused.
12533 (yyerrlab2): New label, which yyerrlab now falls through to.
12534 Compute the error's location by applying YYLLOC_DEFAULT to
12535 the locations of all the symbols that went into the error.
12536 * doc/bison.texinfo (Location Default Action): Mention that
12537 YYLLOC_DEFAULT is also invoked for syntax errors.
12538 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

12540 discarded, not just the last token.

12597 If the user does not define YYSTYPE as a macro, Bison now declares it
12598 using typedef instead of defining it as a macro. POSIX requires this.
12599 For consistency, YYLTYPE is also declared instead of defined.
12600
12601 %union directives can now have a tag before the `{', e.g., the
12602 directive `%union foo {...}' now generates the C code
12603 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
12604 The default union tag is `YYSTYPE', for compatibility with Solaris 9
12605 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
12606 instead of `yyltype'.
12607
12608 `yystype' and `yyltype' are now obsolescent macros instead of being
12609 typedefs or tags; they are no longer documented and will be
12610 withdrawn in a future release.

12618 for backward compatibility.
12619 * data/yacc.c: Likewise.
12620

12622 does not specify a union tag. This is for compatibility with
12623 Solaris 9 yacc.
12624
12625 * src/parse-gram.y (add_param): 2nd arg is now char * not char

12644 to return when scanning braced code.

13045 instead of returning ID immediately, since we need to search for
13046 a subsequent colon.
13047 (<INITIAL>"'", "\""): Save token_start.

13250 ((...));' if a single statement is desired (e.g. before `else').

13603 Use new @ escapes consistently. Represent brackets with @{ and @}
13604 rather than @<:@ and @:>@, since this works a bit better with dumb
13605 editors like vi. Represent @ with @@, since @ is now consistently
13606 an escape. Use @oline@ and @ofile@ rather than __oline__ and
13607 __ofile__, to avoid unexpected expansions. Similarly, use @output
13608 rather than #output.

13658 them with auto vars.
13659 Switch to new escape scheme, where @ is the escape character uniformly.

13661 buffer when parsing non-escaped text.

13676 counted in the token inserted at end of file. Now takes
13677 location_t *, not location_t, so that the location can be
13678 adjusted. All uses changed.

14257 Stop using the "enum_" trick for K&R-style function definitions;
14258 it confused me, and I was the author! Instead, assume that people

14260 perhaps?) will run ansi2knr.

14392 Let nondeterministic skeletons be usable with deterministic
14393 tables.
14394
14395 With the patch, GAWK compiled by GCC without -O2 passes its test
14396 suite using a GLR parser driven by LALR tables. It fails with -O2
14397 because `struct stat' gives two different answers on my machine:
14398 88 (definition of an auto var) and later 96 (memset on this var).
14399 Hence the stack is badly corrumpted. The headers inclusion is to
14400 blame: if I move the awk.h inclusion before GLR's system header
14401 inclusion, the two struct stat have the same size.

14455 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,

18071 * src/reader.c (readgram): Don't add the rule 0 if there were no
18072 rules read. In other words, add it _after_ having performed
18073 grammar sanity checks.
18074 Fixes the `tests/regression.at (Invalid input: 1)' Failure.

18093 the reductions of the first state which was mistakenly confused
18094 with the final state because precisely final_state was initialized
18095 to 0.

18160 twice `Now at end of input', therefore there are two lines less to

18175 these states are automatically computed from the initial state.
18176 (generate_states): Adjust.
18177 * src/print.c: When reporting a rule number to the user, substract
18178 1, so that the axiom rule is rule 0, and the first user rule is 1.
18179 * src/reduce.c: Likewise.
18180 * src/print_graph.c (print_core): For the time being, just as for
18181 the report, depend upon --trace-flags to dump the full set of
18182 items.
18183 * src/reader.c (readgram): Once the grammar read, insert the rule
18184 0: `$axiom: START-SYMBOL $'.
18185 * tests/set.at: Adjust: rule 0 is now displayed, and since the
18186 number of the states has changed (the final state is no longer
18187 necessarily the last), catch up.

18192 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0

18210 * src/reader.c (eoftoken): New.
18211 (parse_token_decl): If the token being defined has value `0', it
18212 is the eoftoken.
18213 (packsymbols): No longer hack `tags' to insert `$' by hand.
18214 Be sure to preserve the value of the eoftoken.
18215 (reader): Make sure eoftoken is defined.
18216 Initialize nsyms to 0: now eoftoken is created just like the others.
18217 * src/print.c (print_grammar): Don't special case the eof token.
18218 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
18219 lie anyway, albeit pleasant.
18220 * tests/calc.at: Exercise error messages with eoftoken.
18221 Change the grammar so that empty input is invalid.
18222 Adjust expectations.

18651 but that's to be addressed elsewhere.
18652 No longer output the rule numbers, but do output the state number.

19062 Because useless nonterminals are now kept alive (instead of being

19072 `shift_symbol', containing the symbol that can be shifted from a
19073 given state.
19074 Deobfuscate, i.e., allocate, use and free `symbol_count' here
19075 only, and...

19657 * tests/calc.at, tests/output.at, tests/regression.at,
19658 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
19659 now the tests are run in private dirs, therefore AC_CLEANUP and
19660 family can be simplified to 0-ary.
19661 * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
19662 use abs. path to find config.h.
19663 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
19664 stderr, there can be way too much random noise.

19686 * src/lex.c (parse_percent_token): Replace equal_offset with
19687 arg_offset.
19688 arg is const.
19689 Be sure to strdup `arg' when used, since there is no reason for

21458 The location tracking mechanism is precious for parse error
21459 messages. Nevertheless, it is enabled only when `@n' is used in
21460 the grammar, which is a different issue (you can use it in error

21462 be another means to enable it.

21494 Test also `--verbose', `--defines' and `--name-prefix'. Testing
21495 the latter demonstrates a flaw in the handling of non debugging
21496 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
21497 was used in order to simplify:
21498
21499 #if YYDEBUG
21500 if (yydebug)
21501 {
21502 ...

21508 if (yydebug)
21509 {
21510 ...
21511 }
21512

21565 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
21566 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
21567 difficult and introduced a lot of core dump. It turns out that
21568 Bison used an implementation of `xmalloc' based on `calloc', and
21569 at various places it does depend upon the initialization to 0. I
21570 have not tried to isolate the pertinent places, and all the former
21571 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

22660 declaration to allow a multi-character symbol as an alias.
22661 (parse_thong_decl): New function.

22672 Revised and use multiple warnxxx functions to avoid using VARARGS1.
22673 (read_declarations): Improve the error message for
22674 an invalid character. Do not abort.

22702 (lex): Use literalchar.
22703 (lex): Implemented "..." tokens.
22704 (literalchar, lex, parse_percent_token): Made tokenbuffer
22705 always contain the token. This includes growing the token
22706 buffer while reading an integer.
22707 (parse_percent_token): Replaced if-else statement with percent_table.
22708 (parse_percent_token): Added % declarations as another
22709 way to specify the flags -n, -l, and -r. Also added hooks for
22710 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
22711 major changes to files.c.
22712 (lex) Retain in the incoming stream a character following
22713 an incorrect '/'.
22714 (skip_white_space, lex): Revised most error messages
