105
106 Add "%define assert" to variants.
107 This is used to help the user catch cases where some value gets
108 ovewritten by a new one. This should not happen, as this will
109 probably leak.
110
111 Unfortunately this uncovered a bug in the C++ parser itself: the
112 lookahead value was not destroyed between two calls to yylex. For
113 instance if the previous lookahead was a std::string, and then an int,
114 then the value of the std::string was correctly taken (i.e., the
115 lookahead was now an empty string), but std::string structure itself
116 was not reclaimed.
117
118 This is now done in variant::build(other&) (which is used to take the
119 value of the lookahead): other is not only stolen from its value, it
120 is also destroyed. This incurs a new performance penalty of a few
121 percent, and union becomes faster again.
122
123 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.
124 (b4_variant_if): New.
125 (variant::built): New.
126 Use it whereever the status of the variant changes.
127 * etc/bench.pl.in: Check the penalty of %define assert.

401
402 Fuse the three stacks into a single one.
403 In order to make it easy to perform benchmarks to ensure that there are no
404 performance loss, lalr1.cc is forked into lalr1-fusion.cc. Eventually,
405 lalr1-fusion.cc will replace lalr1.cc.
406
407 Meanwhile, to make sure that lalr1-fusion.cc is correctly exercized by the
408 test suite, the user must install a symbolic link from lalr1.cc to it.
409
410 Instead of having three stacks (state, value, location), use a stack
411 of triples. This considerably simplifies the code (and it will be
412 easier not to require locations as currently does the C++ parser),
413 and also gives a 10% speedup according to etc/bench (probably mainly since
414 memory allocation is done once instead of three times).
415
416 Another motivation is to make it easier to destruct properly
417 semantic values: now that they are bound to their state (hence
418 symbol type) it will be easier to call the appropriate destructor.
419
420 These changes should probably benefit the C parser too.
421
422 * data/lalr1.cc: Copy as... * data/lalr1-fusion.cc: this new

434 Push the state, value, and location at the same time.
435 This is needed to prepare a forthcoming patch that fuses the three
436 stacks into one.
437
438 * data/lalr1.cc (parser::yypush_): New.
439 (parser::yynewstate): Change the semantics: instead of arriving to
440 this label when value and location have been pushed, but yystate
441 is to be pushed on the state stack, now the three of them must
442 have been pushed before. yystate still must be the new state.
443 This allows to use yypush_ everywhere instead of individual
444 handling of the stacks.

465 Use variants to support objects as semantic values.
466 This patch was inspired by work by Michiel De Wilde. But he used Boost
467 variants which (i) requires Boost on the user side, (ii) is slow, and
468 (iii) has useless overhead (the parser knows the type of the semantic value
469 there is no reason to duplicate this information as Boost.Variants do).
470
471 This implementation reserves a buffer large enough to store the largest
472 objects. yy::variant implements this buffer. It was implemented with
473 Quentin Hocquet.

482 (parser::parse): If variants are requested, define
483 parser::union_type, parser::variant, change the definition of
484 semantic_type, construct $$ before running the user action instead
485 of performing a default $$ = $1.
486 * examples/variant.yy: New.
487 Based on an example by Michiel De Wilde.

2170 * src/lalr.c (state_lookahead_tokens_count): For code readability,
2171 move the check for disabled transitions to an aver since conflict
2172 resolution hasn't happened yet.
2173
2174 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
2175 labels a state as inconsistent just because it has error transitions.
2176 The original form of this check appeared in revision 1.1 of lalr.c,
2177 which was committed on 1991-12-21. Now (at least), changing the
2178 consistency label on such a state appears to have no useful effect in
2179 any of the places it is examined, which I enumerate below. The key
2180 point to understanding each item in this enumeration is that a state
2181 with an error transition is labelled consistent in the first place only
2182 if it has no rules, so the check cannot matter for states that have
2183 rules. (1) Labelling a state as inconsistent will cause set_conflicts
2184 to try to identify its conflicts, and a state must have *rules* to have
2185 conflicts. (2) Labelling a state as inconsistent will affect how
2186 action_row sets the default *rule* for the state. (3) Labelling a
2187 state as inconsistent will cause build_relations to add lookback edges
2188 to *rules* in that state.
2189 * src/state.h (struct state): Word the comment for member consistent
2190 more carefully.

2828 Instead of having skeletons declare all valid %define variables and

2831 variable or qualifier is not used by the skeleton in the current
2832 invocation regardless of whether it might sometimes be used by that
2833 skeleton in other invocations. Also, move all %define value macros to

3219 For push mode, convert yyparse from a macro to a function, invoke yylex
3220 instead of passing a yylexp argument to yypull_parse, and don't
3221 generate yypull_parse or yyparse unless %push-pull-parser is declared.
3222 Discussed starting at

3228 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
3229 any time a pull parser is requested.
3230 Don't #define this as a wrapper around yypull_parse. Instead, when
3231 both push and pull are requested, make it a function that does that
3232 same thing.
3233 (yypull_parse): If there's a b4_prefix, #define this to
3234 b4_prefix[pull_parse] when both push and pull are requested.
3235 Don't define this as a function unless both push and pull are
3236 requested.
3237 Remove the yylexp argument and hard-code yylex invocation instead.
3238 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
3239 %push-parser.
3240 * src/getargs.c (pull_parser): New global initialized to true.

3246 %push-parser.

3266 yypush_parse invocations after the first, be sure to assign yyn its old
3267 value again.
3268 (yypstate_new): Don't bother initializing the yyresult field since the
3269 initial value isn't used.
3270 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
3271 remove the #define that, in push mode, set it to yyps->NAME.
3272 * etc/Makefile.am: New.
3273 * etc/bench.pl: Remove and build it instead from...
3274 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
3275 "tests/bison" from the build directory by default rather than just
3276 invoking "bison" from $PATH.

3278 don't define yyparse_wrapper, and don't #define yyparse.

3297 Enable push parsers to operate in impure mode. Thus, %push-parser no
3298 longer implies %pure-parser. The point of this change is to move
3299 towards being able to test the push parser code by running the entire
3300 test suite as if %push-parser had been declared.
3301 * data/push.c (yypush_parse): For impure mode, remove the
3302 yypushed_char, yypushed_val, and yypushed_loc arguments.
3303 Instead, declare these as local variables initialized to the global
3304 yychar, yylval, and yylloc.
3305 For the first yypush_parse invocation only, restore the initial values
3306 of these global variables when it's time to read a token since they
3307 have been overwritten.
3308 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
3309 %push-parser.
3310 * tests/calc.at (Simple LALR(1) Calculator): Always declare
3311 %pure-parser along with %push-parser since this test case was designed

3352 Rearrange initialization of the parser state variables so that the

3355 initialized (with b4_location_initial_line and
3356 b4_location_initial_column) upon calling yypush_parse. However, that
3357 initialization now overwrites the first token's location;
3358 %initial-action assigning @$ already did the same thing, and both bugs
3359 will be fixed in a later patch.

3589 For pkgdatadir muscle, maintain previous functionality by using
3590 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
3591 is that b4_pkgdatadir is used inside m4_include in the skeletons, so

4460 Whether the default %destructor/%printer applies to a particular symbol
4461 isn't a question of whether the user *declares* that symbol (in %token,
4462 for example). It's a question of whether the user by any means
4463 *defines* the symbol at all (by simply using a char token, for
4464 example). $end is defined by Bison whereas any other token with token
4465 number 0 is defined by the user. The error token is always defined by
4466 Bison regardless of whether the user declares it with %token, but we
4467 may one day let the user define error as a nonterminal instead.
4468 * NEWS (2.3+): Say "user-defined" instead of "user-declared".

4872 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to

4986 warnings about types for $$, $n, @$, and @n can't be reported yet.
4987 (packgram): Translate the action and invoke grammar_rule_check now that
4988 all symbol declarations have been parsed.
4989 * src/scan-code.l (handle_action_dollar): Now that this is invoked
4990 after parsing the entire grammar file, the symbol list here in the case
4991 of a midrule is actually the midrule's empty RHS, so reference its
4992 parent rule's RHS where necessary.
4993 On the other hand, now that you can already know it's a midrule, you

5001 terminates a rule. symbol_list_print already does this correctly.
5002 * src/symlist.h (symbol_list.midrule_parent_rule,

5201 The Translation Project changed its way of publishing translations
5202 to maintainers. I haven't received any responses to my request
5203 for supporting the old way, or for documenting the new way. I
5204 have modified 'bootstrap' to use screen scraping
5205 (in this case, HTML scraping). This is unreliable and inelegant,

5506 works around a bug reported independently by Keith Thompson and by
5507 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
5508 stderr rather than stdout, messing up the build logs.

5521 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
5522 state before an empty RHS is always resolved here. Only the location
5523 of that state is guaranteed to be resolved, and that's enough. This
5524 fixes the remaining bug reported by Derek M. Jones in
5525 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5526 * tests/glr-regression.at (Uninitialized location when reporting
5527 ambiguity): Test the above case.
5528 Also, the embedded comments in this test case claim it checks the case
5529 of an empty RHS that has inherited the initial location. However, the
5530 corresponding LHS was already resolved, so yyresolveLocations didn't
5531 actually have reason to modify it. Fix this by forcing
5532 nondeterministic operation at the beginning of the parse.

5951 During deterministic GLR operation, user actions should be able to
5952 influence the parse by changing yychar. To make this easier to fix and

5981 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
5982 got from <http://bro-ids.org/download.html>. The bug is that
5983 when two actions appeared in succession, the second one was
5984 scanned before the first one was added to the grammar rule
5985 as a midrule action. Bison then output the incorrect warning
5986 "parse.y:905.17-906.36: warning: unused value: $3".

6277 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
6278 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
6279 appropriately during nondeterministic operation.

6281 members to store the current lookahead to be used by the deferred
6282 user action.
6283 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack

6315 * data/glr.c (yyresolveValue): When merging semantic options, if at
6316 least one user action succeeds but a later one cuts the parse, then
6317 destroy the semantic value before returning rather than leaking it.
6318 (yyresolveStates): If a user action cuts the parse and thus
6319 yyresolveValue fails, ignore the (unset) semantic value rather than
6320 corrupting the yyGLRState, and empty the semantic options list since
6321 the user actions should have called all necessary destructors.

7454 AT_PARSER_CHECK for data that contains backslashes. It currently
7455 uses 'echo', and 'echo' isn't portable if its argument contains
7456 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
7457 that the byte '\0xff' is not printable in the C locale; it is,
7458 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
7459 not printable, so use '\0x81' to test.

7586 the new runtime-po domain, prime the pump by extracting the

7618 the 2005-04-17 change, which is now accomplished (mostly) via
7619 changes in the parsers as described above.
7620 * tests/regression.at (Token definitions, Web2c Actions):

7625 Fix more problems reported by twlevo@xs4all.nl.
7626 * tests/cxx-type.at: Don't pipe output of ./types through sed to
7627 remove trailing spaces. This loses the exit status of ./types,
7628 and isn't needed since ./types shouldn't be emitting trailing
7629 spaces.
7630 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
7631 as the stack isn't valid in that case.

7643 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
7644 overly-picky compilers that reject 'char *foo = "bar";'.
7645
7646 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
7647 to FILE * parameter, not to stderr. This fixes a typo introduced
7648 in the 2005-07-12 change.
7649

7666 * data/lalr1.cc (yyerrlab): Likewise.
7667 * data/glr.c (yyparse): Pop everything off the stack before
7668 freeing it, so that destructors get called properly.

7691 eases translation.

7702 can be understood only by someone who can read the
7703 (English-language) source code.
7704
7705 Generate runtime-po/bison-runtime.pot automatically, so that we
7706 don't have to worry about garbage getting in that file. We'll
7707 make sure after the next official release that old msgids don't

7713 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
7714 Fix typos in explanations of the runtime file.
7715 * bootstrap: Change gettext keyword from YYI18N to YY_.
7716 Use standard Makefile.in.in in runtime-po, since we'll arrange
7717 for backward-compatible bison-runtime.po files in a different way.
7718 * data/glr.c (YY_): New macro, from yacc.c.
7719 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
7720 Translate messages intended for users.
7721 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
7722 the wording in the other skeletons. We don't know that the memory
7723 is virtual.
7724 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
7725 Use same method that yacc.c uses.
7726 Don't translate debugging messages.
7727 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
7728 it doesn't work (yet), and requires C++ expertise to fix.
7729 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
7730 Move defn to a more logical place, to be consistent with other
7731 skeletons.
7732 Don't translate debugging messages.
7733 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
7734 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
7735 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
7736 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

7759 if YYABORT is used).

8201 from here....
8202 (yyreturn): to here. That way, destructors are called properly
8203 even if the stack overflows, or the user calls YYACCEPT or
8204 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
8205 (yyoverflowlab): Destroy the lookahead.

8247 overflow. Change "virtual memory" to "memory" in diagnostic, since

8793 (build_relations): Initialize includes[i] in all cases.

8795 and rules[ruleno].precsym. Initialize members in order.

8798 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.

8940 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
8941 whether the reducion was empty or not. This leaves room to
8942 improve the use of YYLLOC_DEFAULT in such a case.
8943 lalr1.cc is still experimental, so changing this is acceptable.
8944 And finally, there are probably not many users who changed the
8945 handling of locations in GLR, so changing is admissible too.

9048 This allows to replace code relying on the implementation of
9049 locations by portable code.
9050 * data/yacc.c (yylerrsp): Replace with...
9051 (yyerror_range): this.

9079 including for the error token.
9080 * data/lalr1.cc (symprint_): Output the location.
9081 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
9082 output the location within the %printer.
9083 Activate GLR tests, at least to make sure they compile properly.
9084 They still don't pass though.
9085 * tests/calc.at: Adjust expect verbose output, since now "Entering

9089
9090 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
9091 Bison directive from the Bison file to the invocation of this
9092 macro, so that these directives are passed to
9093 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
9094 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
9095 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
9096 the extra Bison directives instead of the whole series.
9097 Change the grammar so that there are recoverable errors, and
9098 unrecoverable errors. Now we can have the parser give up before
9099 consuming the whole input. As a result we now can observe that
9100 the lookahead is freed when needed.
9101 Change the parser source to parse argv[1] instead of a hard coded
9102 string.
9103 Simplify yylex, and give a value and location to EOF.
9104 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
9105 passed directives already coded in the file.
9106 Add some tests to check the location of "error".
9107 For some tests, the C++ parser is correct, and not yacc.c.
9108 For other tests, they provide different, but unsatisfying, values,
9109 so keep the C++ value so that at least one parser is "correct"
9110 according to the test suite.
9111 (Actions after errors): Remove, this is subsumed by the
9112 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

9290 Spent a few hours checking out which prerequisite versions the

9292 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
9293 a seemingly endless set of combinations of versions more recent

9563
9564 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
9565 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
9566 unused declaration.
9567
9568 * tests/synclines.at (%union synch line): Put a dummy member in

9685 There's no need to mention top_builddir since Automake does that
9686 for us.

9812 When reducing initial empty rules, Bison parser read an initial
9813 location that is not defined. This results in garbage, and that
9814 affects Bison's own parser. Therefore we need (i) to extend Bison

10111 The problem was that GLR parsers did not conform to the C standard,
10112 because actions like { $1 = $2 + $3; } expanded to expressions
10113 that invoked YYFILL in separate subexpressions, and YYFILL assigned
10114 to a local variable. The C standard says that expressions
10115 like (var = f ()) + (var = f ()) have undefined behavior.
10116 Another problem was that GCC sometimes issues warnings that
10117 yyfill and its parameters are unused.
10118
10119 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
10120 as possibly unused.
10121 (yyfill): New function.
10122 (YYFILL): Use it.
10123 (yyuserAction): Change type of yynormal to bool, so that it matches
10124 the new yyfill signature. Mark it as possibly unused.

10127 Follow up on a bug I reported in February, where a Bison-generated
10128 parser can loop. Provide a test case and a fix for yacc.c. I
10129 don't have a fix for lalr1.cc or for glr.c, unfortunately.
10130 The original bug report is in:

10133 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
10134 macro's size was becoming unwieldy.
10135 (yyerrlab): Do not discard an empty lookahead symbol, as this
10136 might destroy garbage.
10137 (yyerrorlab): New label, with the old contents of YYERROR,
10138 plus the following change: pop the stack of rhs corresponding
10139 to the production that invoked YYERROR. That is how Yacc
10140 behaves, and POSIX requires this behavior.
10141 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10142 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10143 Define 'alarm' to do nothing if unistd.h is not available.
10144 Add a new rule "exp: '-' error;" to test the above change to
10145 data/yacc.c. Use 'alarm' to abort any test taking longer than
10146 10 seconds, as it's probably looping.
10147 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
10148 Also, the new yacc.c generates two fewer diagnostics for an
10149 existing test.

10776 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
10777 we don't need to worry about yyerrlab1 being reported as an

10781 should vanish.

10799 popped). This means that the initial elements will not be freed
10800 explicitly, as is the case in yacc.c; it is not a problem, as
10801 these elements have fake values.

10910 * doc/bison.texinfo (Understanding): Use Yacc style for
10911 conflict reports. Also, use new way of locating rules.
10912 * src/conflicts.c (conflict_report):
10913 Renamed from conflict_report_yacc, removing the old
10914 'conflict_report'. Translate the entire conflict report at once,
10915 so that we don't assume that "," has the same interpretation in
10916 all languages.
10917 (conflicts_output): Use Yacc-style conflict report for each state,
10918 instead of our more-complicated style.
10919 (conflicts_print): Use Yacc-style conflict report, except print
10920 the input file name when not emulating Yacc.
10921 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
10922 Conflicted Reduction, %expect not enough, %expect too much,

10935 This problem was originally reported by Paul Hilfinger in

10938 * data/yacc.c (yyparse): New local var yylerrsp, to record the
10939 top of the location stack's error locations.
10940 (yyerrlab): Set it. When discarding a token, push its location
10941 onto yylerrsp so that we don't lose track of the error's end.
10942 (yyerrlab1): Now is only the target of YYERROR, so that we can
10943 properly record the location of the action that failed. For GCC
10944 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
10945 GCC warning about yyerrlab1 being unused if YYERROR is unused.
10946 (yyerrlab2): New label, which yyerrlab now falls through to.
10947 Compute the error's location by applying YYLLOC_DEFAULT to
10948 the locations of all the symbols that went into the error.
10949 * doc/bison.texinfo (Location Default Action): Mention that
10950 YYLLOC_DEFAULT is also invoked for syntax errors.
10951 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10952 Error locations include the locations of all the tokens that were
10953 discarded, not just the last token.

11010 If the user does not define YYSTYPE as a macro, Bison now declares it
11011 using typedef instead of defining it as a macro. POSIX requires this.
11012 For consistency, YYLTYPE is also declared instead of defined.
11013
11014 %union directives can now have a tag before the `{', e.g., the
11015 directive `%union foo {...}' now generates the C code
11016 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
11017 The default union tag is `YYSTYPE', for compatibility with Solaris 9
11018 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
11019 instead of `yyltype'.
11020
11021 `yystype' and `yyltype' are now obsolescent macros instead of being
11022 typedefs or tags; they are no longer documented and will be
11023 withdrawn in a future release.

11030 (yyltype, yystype): New (and obsolescent) macros,
11031 for backward compatibility.
11032 * data/yacc.c: Likewise.
11033
11034 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
11035 does not specify a union tag. This is for compatibility with
11036 Solaris 9 yacc.
11037
11038 * src/parse-gram.y (add_param): 2nd arg is now char * not char

11041 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,

11055 has (or usually has) an immediately-following braced code.

11057 to return when scanning braced code.

11387 then the . include files in double-quotes (alphabetized). Fix
11388 dependency breakages encountered in this process, as follows:

11458 instead of returning ID immediately, since we need to search for
11459 a subsequent colon.

12011 Revamp to fix many (but not all) of the C- and M4-related quoting

12013 by Jan Hubicka when processing the Bash grammar; see:

12016 Use new @ escapes consistently. Represent brackets with @{ and @}
12017 rather than @<:@ and @:>@, since this works a bit better with dumb
12018 editors like vi. Represent @ with @@, since @ is now consistently
12019 an escape. Use @oline@ and @ofile@ rather than __oline__ and
12020 __ofile__, to avoid unexpected expansions. Similarly, use @output
12021 rather than #output.
12022
12023 * data/c.m4 (b4_copyright): Omit file name from comment, since
12024 the file name could contain "*/".
12025 (b4_synclines_flag): Don't quote the 2nd argument; it should already
12026 be quoted. All uses changed.

12040 mishandled funny characters in file names, and anyway it isn't
12041 needed any more.
12042 * data/yacc.c: Likewise.

12055 (prepare): Don't insert output_infix, output_prefix,
12056 output_parser_name, output_header_name; this is now down by scan-skel.

12067 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
12068 Use new escapes @{ and @} for [ and ].
12069
12070 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
12071 them with auto vars.
12072 Switch to new escape scheme, where @ is the escape character uniformly.
12073 Abort if a stray escape character is found. Avoid unbounded input
12074 buffer when parsing non-escaped text.
12075

12086 (yygetLRActions, yyrecoverParseError): Use them.

12089 counted in the token inserted at end of file. Now takes
12090 location_t *, not location_t, so that the location can be
12091 adjusted. All uses changed.

12805 Let nondeterministic skeletons be usable with deterministic
12806 tables.
12807
12808 With the patch, GAWK compiled by GCC without -O2 passes its test
12809 suite using a GLR parser driven by LALR tables. It fails with -O2
12810 because `struct stat' gives two different answers on my machine:
12811 88 (definition of an auto var) and later 96 (memset on this var).
12812 Hence the stack is badly corrumpted. The headers inclusion is to
12813 blame: if I move the awk.h inclusion before GLR's system header
12814 inclusion, the two struct stat have the same size.

12868 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,

13036
13037 * configure.ac (AC_INIT), NEWS: Increment version number.
13038
13039 * doc/bison.texinfo: Minor spelling, grammar, and white space
13040 fixes.
13041 (Symbols): Mention that any negative value returned from yylex
13042 signifies end-of-input. Warn about negative chars. Mention
13043 the portable Standard C character set.
13044
13045 The GNU coding standard says CFLAGS and YFLAGS are reserved
13046 for the installer to set.
13047 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
13048 * src/Makefile.am (AM_CFLAGS): Likewise.
13049 (AM_YFLAGS): Renamed from YFLAGS.
13050
13051 Fix some MAX and MIN problems.
13052 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
13053 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
13054 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
13055 * src/reader.c (reader): Use it.
13056
13057 * tests/regression.at (Braces parsing): Use grep, not fgrep, as

13130 BITSET_SIZE_MAX): New macros.
13131 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
13132 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
13133 to BITSET_WINDEX_MAX.
13134
13135 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
13136 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,
13137 since we now return the bitset_bindex type (not int).
13138
13139 * lib/bitsetv.c (bitsetv_alloc): Check for arithmetic overflow
13140 when computing sizes.

13286 (yyreportParseError): Use size_t for yysize.
13287 (yy_yypstack): No longer nested inside yypstates, as nested
13288 functions are not portable. Do not assume size_t is the
13289 same width as int.
13290 (yypstates): Do not assume that ptrdiff_t is the same width
13291 as int, and similarly for yyposn and YYINDEX.
13292
13293 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.

13331
13332 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
13333 PROTOTYPES to check for prototypes, and "defined __STDC__" to
13334 check for void *.
13335
13336 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
13337 size_t; the old version tried to do this but casted improperly.
13338 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
13339 (bitset_test): Now returns int, not unsigned long.
13340
13341 * lib/bitset_stats.c: Include "gettext.h".
13342 (_): New macro.
13343 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
13344 name locals "index", as it generates unnecessary warnings on some
13345 hosts that have an "index" function.
13346
13347 * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
13348 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

13369 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
13370 lib/timevar.c.
13371 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
13372 manual recommends.
13373 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
13374
13375 * src/complain.c (strerror_r): Remove decl; not needed.
13376 (strerror): Use same pattern as ../lib/error.c.
13377
13378 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
13379
13380 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
13381
13382 * src/main.c (main): Cast result of bindtextdomain and textdomain
13383 to void, to avoid a GCC warning when --disable-nls is in effect.
13384
13385 * src/scan-gram.l: Use strings rather than escapes when possible,
13386 to minimize the number of warnings from xgettext.
13387 (handle_action_dollar, handle_action_at): Don't use isdigit,
13388 as it mishandles negative chars and it may not work as expected
13389 outside the C locale.
13390
13391 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
13392 this is a GCC extension and is not portable to other compilers.
13393
13394 * src/system.h (alloca): Use same pattern as ../lib/error.c.
13395 Do not include <ctype.h>; no longer needed.
13396 Do not include <malloc.h>; no longer needed (and generates
13397 warnings on OpenBSD 3.0).
13398
13399 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
13400 it's not portable.
13401
13402 * tests/regression.at: Do not use 'cc -c input.c -o input';
13403 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
13404
13405 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
13406 exit status as failure, not just exit status 1. Sun C exits

16220 The ISO C++ standard is extremely clear about it: stderr is
16221 considered a macro, not a regular symbol (see table 94 `Header
16222 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
16223 Therefore std:: does not apply to it. It still does with fprintf.

16257 Throw away MS-DOS crap: we don't need getpid.
16258 * configure.in: We don't need strndup. It was even causing
16259 problems: because Flex includes the headers *before* us,
16260 _GNU_SOURCE is not defined by config.h, and therefore strndup was
16261 not visible.
16262 * lib/xstrndup.c: New.

16264 Be sure to initialize yylval.muscle member when scanning a MUSCLE.

16277 * src/scan-skel.l: Add the license notice.
16278 Include skeleton.h.
16279 Don't use %option yylineno: it seems that then Flex imagines
16280 REJECT has been used, and therefore it won't reallocate its
16281 buffers (which makes no other sense to me than a bug). It results
16282 in warnings for `unused: yy_flex_realloc'.

16559 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
16560 Sparc, as they were causing more porting problems than the
16561 (minor) performance improvement was worth.

16573 twice `Now at end of input', therefore there are two lines less to

16588 these states are automatically computed from the initial state.
16589 (generate_states): Adjust.
16590 * src/print.c: When reporting a rule number to the user, substract
16591 1, so that the axiom rule is rule 0, and the first user rule is 1.
16592 * src/reduce.c: Likewise.
16593 * src/print_graph.c (print_core): For the time being, just as for

16596 * src/reader.c (readgram): Once the grammar read, insert the rule
16597 0: `$axiom: START-SYMBOL $'.
16598 * tests/set.at: Adjust: rule 0 is now displayed, and since the
16599 number of the states has changed (the final state is no longer
16600 necessarily the last), catch up.

16604 Try to make the use of the eoftoken valid. Given that its value
16605 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0

16623 * src/reader.c (eoftoken): New.
16624 (parse_token_decl): If the token being defined has value `0', it
16625 is the eoftoken.
16626 (packsymbols): No longer hack `tags' to insert `$' by hand.
16627 Be sure to preserve the value of the eoftoken.
16628 (reader): Make sure eoftoken is defined.
16629 Initialize nsyms to 0: now eoftoken is created just like the others.
16630 * src/print.c (print_grammar): Don't special case the eof token.
16631 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
16632 lie anyway, albeit pleasant.
16633 * tests/calc.at: Exercise error messages with eoftoken.
16634 Change the grammar so that empty input is invalid.
16635 Adjust expectations.

16726 the switch/case/break flesh.
16727 Don't parse the user action that might follow the guard, let...
16728 (readgram): do it, i.e., now, there can be an action after a

16773 As much as possible, depend upon nlookaheads, instead of the
16774 `lookaheadsp' member of the following state (since lookaheads of

17062 * src/print_graph.c (print_core): Complete the set of items via
17063 closure. The next-to-final and final states are still unsatisfying,
17064 but that's to be addressed elsewhere.
17065 No longer output the rule numbers, but do output the state number.
17066 A single loop for the shifts + gotos is enough, but picked a

17316 New experimental feature: if --verbose --trace output all the
17317 items of a state, not only its kernel.
17318
17319 * src/print.c (print_core): If `trace_flag', then invoke closure
17320 before outputting the items of the state (print_core is no longer
17321 a correct name them).
17322 (print_results): Invoke new_closure/free_closure if needed.

17475 Because useless nonterminals are now kept alive (instead of being
17476 `destroyed'), we now sometimes examine them, and store information
17477 related to them. Hence we need to know their number, and adjust
17478 memory allocations.

17481 static.
17482 * src/LR0.c (allocate_itemsets): The memory allocated to
17483 `symbol_count' was used for two different purpose: once to count
17484 the number of occurrences of each symbol, and later reassigned to
17485 `shift_symbol', containing the symbol that can be shifted from a
17486 given state.
17487 Deobfuscate, i.e., allocate, use and free `symbol_count' here
17488 only, and...
17489 (new_itemsets): Allocate `shift_symbol' here.
17490 (allocate_itemsets): symbol_count includes useless nonterminals.
17491 Make room for them.

17493 be null.

19871 The location tracking mechanism is precious for parse error
19872 messages. Nevertheless, it is enabled only when `@n' is used in
19873 the grammar, which is a different issue (you can use it in error
19874 message, but not in the grammar per se). Therefore, there should
19875 be another means to enable it.

19907 Test also `--verbose', `--defines' and `--name-prefix'. Testing
19908 the latter demonstrates a flaw in the handling of non debugging
19909 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
19910 was used in order to simplify:
19911
19912 #if YYDEBUG
19913 if (yydebug)
19914 {
19915 ...
19916 }
19917 #endif
19918
19919 into
19920
19921 if (yydebug)
19922 {
19923 ...
19924 }
19925
19926 unfortunately this leads to a CPP conflict when
19927 `--name-prefix=foo' is used since it produces `#define yydebug
19928 foodebug'.

19978 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
19979 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
19980 difficult and introduced a lot of core dump. It turns out that
19981 Bison used an implementation of `xmalloc' based on `calloc', and
19982 at various places it does depend upon the initialization to 0. I
19983 have not tried to isolate the pertinent places, and all the former
19984 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

21068 New function.
21069 (readgram): Use `#if 0' around code that accepted %command
21070 inside grammar rules: The documentation doesn't allow it,
21071 and it will fail since the %command processors scan for the next %.
21072 (parse_token_decl): Extended the %token
21073 declaration to allow a multi-character symbol as an alias.
21074 (parse_thong_decl): New function.
21075 (read_declarations): Added %thong declarations.

21085 Revised and use multiple warnxxx functions to avoid using VARARGS1.
21086 (read_declarations): Improve the error message for
21087 an invalid character. Do not abort.
21088 (read_declarations, copy_guard, copy_action): Use
21089 printable_version to avoid unprintable characters in printed output.
21090 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
21091 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):

21106
21107 * src/lex.h:
21108 Added THONG and NOOP for alias processing.
21109 Added SETOPT for the new code that allows setting options with %flags.
21110
21111 * src/lex.c:
21112 Include getopt.h. Add some extern decls.
21113 (safegetc): New function to deal with EOF gracefully.
21114 (literalchar); new function to deal with reading \ escapes.
21115 (lex): Use literalchar.
21116 (lex): Implemented "..." tokens.
21117 (literalchar, lex, parse_percent_token): Made tokenbuffer
21118 always contain the token. This includes growing the token
21119 buffer while reading an integer.
21120 (parse_percent_token): Replaced if-else statement with percent_table.
21121 (parse_percent_token): Added % declarations as another
21122 way to specify the flags -n, -l, and -r. Also added hooks for
21123 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
21124 major changes to files.c.
21125 (lex) Retain in the incoming stream a character following
21126 an incorrect '/'.
21127 (skip_white_space, lex): Revised most error messages
21128 and changed fatal to warn to avoid aborting.
21129 (percent_table): Added %thong declarations.
