170 yysyntax_error: avoid duplicate lookahead collection.
171 Except when memory reallocation is required, this change
172 eliminates the need to invoke yysyntax_error twice and thus to
173 repeat the collection of lookaheads. It also prepares for
174 future extensions that will make those repetitions more
175 expensive and that will require additional memory management in
176 yysyntax_error. Finally, it fixes an obscure bug already
177 exercised in the test suite.
178 * data/yacc.c (yysyntax_error): Add arguments for message
179 buffer variables stored in the parser. Instead of size, return
180 status similar to yyparse status but indicating success of
181 message creation. Other than the actual reallocation of the
182 message buffer, import and clean up memory management code
183 from...
184 (yyparse, yypush_parse): ... here.

419 More fixes related to last two patches.
420 * data/c.m4 (b4_table_value_equals): Comment that YYID must be
421 defined.
422 * data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Fix
423 yytable comments: zero indicates syntax error not default
424 action.
425 * data/glr.c (yyis_pact_ninf): Rename to...
426 (yypact_value_is_default): ... this.
427 (yyisDefaultedState): Update for rename.
428 (yyis_table_ninf): Rename to...
429 (yytable_value_is_error): ... this, and check for value zero
430 besides just YYTABLE_NINF.
431 (yygetLRActions): Check for default value from yypact. It
432 appears that this check is always performed before this function
433 is invoked, and so adding the check here is probably redundant.
434 However, the code may evolve after this subtlety is forgotten.
435 Also, update for rename to yytable_value_is_error. Because that
436 macro now checks for zero, a different but equivalent branch of

516 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
517 For a \0 and similar escape sequences meaning the null
518 character, report an invalid escape sequence instead of an
519 invalid null character because the latter does not actually
520 appear in the user's input.
521 In all escape sequence complaints, don't escape the initial
522 backslash, and don't quote when the sequence appears at the end
523 of the complaint line unless there's whitespace that quotearg
524 won't escape.

527 characters in character literal" warning for invalid escape
528 sequences; that is, consistently discard those sequences.

3364 * src/lalr.c (state_lookahead_tokens_count): For code readability,
3365 move the check for disabled transitions to an aver since conflict
3366 resolution hasn't happened yet.
3367
3368 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3369 labels a state as inconsistent just because it has error transitions.
3370 The original form of this check appeared in revision 1.1 of lalr.c,
3371 which was committed on 1991-12-21. Now (at least), changing the
3372 consistency label on such a state appears to have no useful effect in
3373 any of the places it is examined, which I enumerate below. The key
3374 point to understanding each item in this enumeration is that a state
3375 with an error transition is labelled consistent in the first place only
3376 if it has no rules, so the check cannot matter for states that have
3377 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3378 to try to identify its conflicts, and a state must have *rules* to have
3379 conflicts. (2) Labelling a state as inconsistent will affect how
3380 action_row sets the default *rule* for the state. (3) Labelling a
3381 state as inconsistent will cause build_relations to add lookback edges
3382 to *rules* in that state.
3383 * src/state.h (struct state): Word the comment for member consistent
3384 more carefully.

3684 Undo most of the 2007-02-03 change, switching to the strcase module
3685 now that gnulib strcase has been fixed.
3686 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
3687 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
3688 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c

3690 * src/getargs.c: Revert 2007-02-03 change, as follows.
3691 Don't include c-strcase.h.
3692 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
3693 strcasecmp has "unspecified behavior" outside the POSIX locale,
3694 but it works fine in practice if at least one argument is ASCII,
3695 as is the case in Bison.

3893 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use

4022 Instead of having skeletons declare all valid %define variables and

4024 and build these lists automatically. Thus Bison will now warn when a
4025 variable or qualifier is not used by the skeleton in the current
4026 invocation regardless of whether it might sometimes be used by that
4027 skeleton in other invocations. Also, move all %define value macros to
4028 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
4029 form, which is replaced by %code.
4030 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...

4491 Enable push parsers to operate in impure mode. Thus, %push-parser no
4492 longer implies %pure-parser. The point of this change is to move
4493 towards being able to test the push parser code by running the entire
4494 test suite as if %push-parser had been declared.
4495 * data/push.c (yypush_parse): For impure mode, remove the
4496 yypushed_char, yypushed_val, and yypushed_loc arguments.
4497 Instead, declare these as local variables initialized to the global
4498 yychar, yylval, and yylloc.
4499 For the first yypush_parse invocation only, restore the initial values
4500 of these global variables when it's time to read a token since they
4501 have been overwritten.
4502 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for

4549 initialized (with b4_location_initial_line and
4550 b4_location_initial_column) upon calling yypush_parse. However, that
4551 initialization now overwrites the first token's location;
4552 %initial-action assigning @$ already did the same thing, and both bugs
4553 will be fixed in a later patch.

5654 Whether the default %destructor/%printer applies to a particular symbol
5655 isn't a question of whether the user *declares* that symbol (in %token,
5656 for example). It's a question of whether the user by any means
5657 *defines* the symbol at all (by simply using a char token, for
5658 example). $end is defined by Bison whereas any other token with token
5659 number 0 is defined by the user. The error token is always defined by
5660 Bison regardless of whether the user declares it with %token, but we
5661 may one day let the user define error as a nonterminal instead.
5662 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
5663 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document

6065 by mbswidth) needs the latter.
6066 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to

6180 warnings about types for $$, $n, @$, and @n can't be reported yet.
6181 (packgram): Translate the action and invoke grammar_rule_check now that
6182 all symbol declarations have been parsed.
6183 * src/scan-code.l (handle_action_dollar): Now that this is invoked
6184 after parsing the entire grammar file, the symbol list here in the case
6185 of a midrule is actually the midrule's empty RHS, so reference its
6186 parent rule's RHS where necessary.
6187 On the other hand, now that you can already know it's a midrule, you

6195 terminates a rule. symbol_list_print already does this correctly.
6196 * src/symlist.h (symbol_list.midrule_parent_rule,

7127 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
7128 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
7129 "warning: sorry: semantics of inline function static data `const
7130 unsigned char translate_table[262]' are wrong (you'll wind up with
7131 multiple copies)".

7133 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
7134 or, xor to not_, and_, or_, and xor_, respectively. This works
7135 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
7136 random system header somewhere that includes the equivalent of
7137 <iso646.h>.

7145 During deterministic GLR operation, user actions should be able to
7146 influence the parse by changing yychar. To make this easier to fix and
7147 to make glr.c easier to evolve in general, don't maintain yytoken in
7148 parallel with yychar; just compute yytoken when needed.
7149 * tests/glr-regression.at (Incorrect lookahead during deterministic
7150 GLR): Check that setting yychar in a user action has the intended
7151 effect.
7152 * data/glr.c (yyGLRStack): Remove yytokenp member.
7153 (yyclearin): Don't set *yytokenp.
7154 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
7155 yychar rather than *yytokenp to determine the current lookahead.
7156 Compute yytoken locally when needed.
7157 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
7158 point to.

7160 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
7161 after `--report' documentation.

7175 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
7176 got from <http://bro-ids.org/download.html>. The bug is that
7177 when two actions appeared in succession, the second one was
7178 scanned before the first one was added to the grammar rule
7179 as a midrule action. Bison then output the incorrect warning
7180 "parse.y:905.17-906.36: warning: unused value: $3".
7181 * src/parse-gram.y (BRACED_CODE, action): These are no longer
7182 associated with a value.
7183 (rhs): Don't invoke grammar_current_rule_action_append.
7184 (action): Invoke it here instead.
7185 * src/reader.c (grammar_midrule_action): Now extern.
7186 (grammar_current_rule_action_append): Don't invoke
7187 grammar_midrule_action; that is now the scanner's job.
7188 * src/reader.h (last_string, last_braced_code_loc):
7189 (grammar_midrule_action): New decls.
7190 * src/scan-gram.l (last_string): Now extern, sigh.
7191 (last_braced_code_loc): New extern variable.
7192 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
7193 rule already has an action.
7194 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
7195 * tests/input.at (AT_CHECK_UNUSED_VALUES):
7196 Add some tests to check that the above changes fixed the bug.

7221 user can override the types.

7509 * data/glr.c (yyresolveValue): When merging semantic options, if at
7510 least one user action succeeds but a later one cuts the parse, then
7511 destroy the semantic value before returning rather than leaking it.
7512 (yyresolveStates): If a user action cuts the parse and thus
7513 yyresolveValue fails, ignore the (unset) semantic value rather than
7514 corrupting the yyGLRState, and empty the semantic options list since
7515 the user actions should have called all necessary destructors.
7516 Simplify code with YYCHK.
7517 * tests/glr-regression.at (Corrupted semantic options if user action
7518 cuts parse): New test case.
7519 (Undesirable destructors if user action cuts parse): New test case.
7520 Before applying any of this patch, this test case never actually failed
7521 for me... but only because the corrupted semantic options usually
7522 masked this bug.
7523 (Leaked merged semantic value if user action cuts parse): New test
7524 case.

7900 * data/yacc.c: Say "parser skeleton" rather than "file", since
7901 it's no longer just a file.

7903 reads like the already-existing exception for C LALR(1) parsers.

8780 the new runtime-po domain, prime the pump by extracting the
8781 relevant strings from the obsolete translations. This code can be
8782 removed once the bison-runtime domain has been translated by each

8820 * tests/cxx-type.at: Don't pipe output of ./types through sed to
8821 remove trailing spaces. This loses the exit status of ./types,
8822 and isn't needed since ./types shouldn't be emitting trailing
8823 spaces.
8824 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
8825 as the stack isn't valid in that case.

8838 overly-picky compilers that reject 'char *foo = "bar";'.
8839
8840 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
8841 to FILE * parameter, not to stderr. This fixes a typo introduced
8842 in the 2005-07-12 change.
8843

8860 * data/lalr1.cc (yyerrlab): Likewise.
8861 * data/glr.c (yyparse): Pop everything off the stack before
8862 freeing it, so that destructors get called properly.

8885 eases translation.

8896 can be understood only by someone who can read the
8897 (English-language) source code.
8898
8899 Generate runtime-po/bison-runtime.pot automatically, so that we
8900 don't have to worry about garbage getting in that file. We'll
8901 make sure after the next official release that old msgids don't

8907 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
8908 Fix typos in explanations of the runtime file.
8909 * bootstrap: Change gettext keyword from YYI18N to YY_.
8910 Use standard Makefile.in.in in runtime-po, since we'll arrange
8911 for backward-compatible bison-runtime.po files in a different way.
8912 * data/glr.c (YY_): New macro, from yacc.c.
8913 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
8914 Translate messages intended for users.
8915 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
8916 the wording in the other skeletons. We don't know that the memory
8917 is virtual.
8918 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
8919 Use same method that yacc.c uses.
8920 Don't translate debugging messages.
8921 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
8922 it doesn't work (yet), and requires C++ expertise to fix.
8923 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
8924 Move defn to a more logical place, to be consistent with other
8925 skeletons.
8926 Don't translate debugging messages.
8927 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
8928 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
8929 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
8930 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

9164 than vsprintf. Allocate a bigger buffer if possible.

9168 the initialization was successful. It might fail if storage was

9825 Fix some problems reported by twlevo at xs4all.
9826 * src/symtab.c (symbol_new): Report an error if the input grammar
9827 contains too many symbols. This is better than calling abort() later.

9857
9858 * data/lalr1.cc (debug_): Rename as...
9859 (yydebug_): so that the parser's internals are always in the yy*
9860 pseudo namespace.
9861 Adjust uses.
9862 (b4_parse_param_decl): Remove the leading comma as it is now only
9863 called as unique argument list.
9864 (Parser::Parser): Remove the constructor accepting a location and
9865 an initial debugging level.

9893 the normal case and one for the error case. Just use the
9894 first one uniformly. Problem reported by Frank Heckenbach.
9895 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
9896 use exactly the same macro in both places.
9897 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
9898 so that the normal-case YYRHSLOC works for the error case too.

9903 we have an array of locations. Use the same macro for both glr
9904 and lalr parsers. Mention YYRHSLOC. Mention what happens when
9905 the index is 0.

9921 Relation sizes are of type relation_node, not size_t (this is
9922 merely a doc fix, since the two types are equivalent).
9923 (relation_transpose): Relation sizes are of type relation_node,
9924 not int.

9968 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
9969 for initial core. Just have a separate core, so we needn't worry
9970 about whether kernel_size and kernel_base are initialized.
9971
9972 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
9973 kernel_size, kernel_items): Remove unnecessary initialization.

9983 This is because all callers pass unsigned int.

9985
9986 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
9987 (build_relations): Initialize includes[i] in all cases.
9988 * src/reader.c (packgram): Always initialize rules[ruleno].prec
9989 and rules[ruleno].precsym. Initialize members in order.
9990 * src/relation.c (relation_transpose): Always initialize new_R[i]
9991 and end_R[i].
9992 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
9993
9994 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
9995 conflict_list[0] was always 0, but now it isn't initialized.
9996
9997 * src/table.c (table_grow): When conflict_table grew, the grown
9998 area wasn't cleared. Fix this.

10134 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
10135 whether the reducion was empty or not. This leaves room to
10136 improve the use of YYLLOC_DEFAULT in such a case.
10137 lalr1.cc is still experimental, so changing this is acceptable.
10138 And finally, there are probably not many users who changed the
10139 handling of locations in GLR, so changing is admissible too.
10140

10284 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
10285 Bison directive from the Bison file to the invocation of this
10286 macro, so that these directives are passed to
10287 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
10288 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
10289 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10290 the extra Bison directives instead of the whole series.
10291 Change the grammar so that there are recoverable errors, and
10292 unrecoverable errors. Now we can have the parser give up before
10293 consuming the whole input. As a result we now can observe that
10294 the lookahead is freed when needed.
10295 Change the parser source to parse argv[1] instead of a hard coded
10296 string.
10297 Simplify yylex, and give a value and location to EOF.
10298 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10299 passed directives already coded in the file.
10300 Add some tests to check the location of "error".
10301 For some tests, the C++ parser is correct, and not yacc.c.
10302 For other tests, they provide different, but unsatisfying, values,
10303 so keep the C++ value so that at least one parser is "correct"
10304 according to the test suite.
10305 (Actions after errors): Remove, this is subsumed by the
10306 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

10487 a seemingly endless set of combinations of versions more recent

11006 When reducing initial empty rules, Bison parser read an initial
11007 location that is not defined. This results in garbage, and that
11008 affects Bison's own parser. Therefore we need (i) to extend Bison

11303 Fix a GLR parser bug I reported in February; see

11305 The problem was that GLR parsers did not conform to the C standard,
11306 because actions like { $1 = $2 + $3; } expanded to expressions
11307 that invoked YYFILL in separate subexpressions, and YYFILL assigned
11308 to a local variable. The C standard says that expressions
11309 like (var = f ()) + (var = f ()) have undefined behavior.
11310 Another problem was that GCC sometimes issues warnings that
11311 yyfill and its parameters are unused.
11312
11313 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
11314 as possibly unused.
11315 (yyfill): New function.
11316 (YYFILL): Use it.
11317 (yyuserAction): Change type of yynormal to bool, so that it matches
11318 the new yyfill signature. Mark it as possibly unused.

11321 Follow up on a bug I reported in February, where a Bison-generated
11322 parser can loop. Provide a test case and a fix for yacc.c. I
11323 don't have a fix for lalr1.cc or for glr.c, unfortunately.
11324 The original bug report is in:

11326
11327 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
11328 macro's size was becoming unwieldy.
11329 (yyerrlab): Do not discard an empty lookahead symbol, as this
11330 might destroy garbage.
11331 (yyerrorlab): New label, with the old contents of YYERROR,
11332 plus the following change: pop the stack of rhs corresponding
11333 to the production that invoked YYERROR. That is how Yacc
11334 behaves, and POSIX requires this behavior.
11335 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
11336 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
11337 Define 'alarm' to do nothing if unistd.h is not available.
11338 Add a new rule "exp: '-' error;" to test the above change to
11339 data/yacc.c. Use 'alarm' to abort any test taking longer than
11340 10 seconds, as it's probably looping.
11341 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11342 Also, the new yacc.c generates two fewer diagnostics for an
11343 existing test.

11971 we don't need to worry about yyerrlab1 being reported as an

11993 popped). This means that the initial elements will not be freed
11994 explicitly, as is the case in yacc.c; it is not a problem, as
11995 these elements have fake values.

12104 * doc/bison.texinfo (Understanding): Use Yacc style for
12105 conflict reports. Also, use new way of locating rules.
12106 * src/conflicts.c (conflict_report):
12107 Renamed from conflict_report_yacc, removing the old
12108 'conflict_report'. Translate the entire conflict report at once,
12109 so that we don't assume that "," has the same interpretation in
12110 all languages.
12111 (conflicts_output): Use Yacc-style conflict report for each state,
12112 instead of our more-complicated style.
12113 (conflicts_print): Use Yacc-style conflict report, except print
12114 the input file name when not emulating Yacc.
12115 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
12116 Conflicted Reduction, %expect not enough, %expect too much,

12128 Fix a bug where error locations were not being recorded correctly.
12129 This problem was originally reported by Paul Hilfinger in

12132 * data/yacc.c (yyparse): New local var yylerrsp, to record the
12133 top of the location stack's error locations.
12134 (yyerrlab): Set it. When discarding a token, push its location
12135 onto yylerrsp so that we don't lose track of the error's end.
12136 (yyerrlab1): Now is only the target of YYERROR, so that we can
12137 properly record the location of the action that failed. For GCC
12138 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
12139 GCC warning about yyerrlab1 being unused if YYERROR is unused.
12140 (yyerrlab2): New label, which yyerrlab now falls through to.
12141 Compute the error's location by applying YYLLOC_DEFAULT to
12142 the locations of all the symbols that went into the error.
12143 * doc/bison.texinfo (Location Default Action): Mention that
12144 YYLLOC_DEFAULT is also invoked for syntax errors.
12145 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
12146 Error locations include the locations of all the tokens that were
12147 discarded, not just the last token.

12204 If the user does not define YYSTYPE as a macro, Bison now declares it
12205 using typedef instead of defining it as a macro. POSIX requires this.
12206 For consistency, YYLTYPE is also declared instead of defined.
12207
12208 %union directives can now have a tag before the `{', e.g., the
12209 directive `%union foo {...}' now generates the C code
12210 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
12211 The default union tag is `YYSTYPE', for compatibility with Solaris 9
12212 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
12213 instead of `yyltype'.
12214
12215 `yystype' and `yyltype' are now obsolescent macros instead of being
12216 typedefs or tags; they are no longer documented and will be
12217 withdrawn in a future release.
12218

12222 (struct YYLTYPE): Renamed from struct yyltype.
12223 (YYLTYPE): Renamed from yyltype.
12224 (yyltype, yystype): New (and obsolescent) macros,
12225 for backward compatibility.
12226 * data/yacc.c: Likewise.
12227
12228 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
12229 does not specify a union tag. This is for compatibility with
12230 Solaris 9 yacc.
12231
12232 * src/parse-gram.y (add_param): 2nd arg is now char * not char

12235 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,

12237 trailing " {...}". Now of type <chars>.
12238 (grammar_declaration): Adjust to bundled tokens.
12239 (code_content): Remove; stripping is now done by add_param.

12249 has (or usually has) an immediately-following braced code.

12251 to return when scanning braced code.

13210 Use new @ escapes consistently. Represent brackets with @{ and @}
13211 rather than @<:@ and @:>@, since this works a bit better with dumb
13212 editors like vi. Represent @ with @@, since @ is now consistently
13213 an escape. Use @oline@ and @ofile@ rather than __oline__ and
13214 __ofile__, to avoid unexpected expansions. Similarly, use @output
13215 rather than #output.
13216
13217 * data/c.m4 (b4_copyright): Omit file name from comment, since
13218 the file name could contain "*/".

13261 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
13262 Use new escapes @{ and @} for [ and ].
13263
13264 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
13265 them with auto vars.
13266 Switch to new escape scheme, where @ is the escape character uniformly.
13267 Abort if a stray escape character is found. Avoid unbounded input
13268 buffer when parsing non-escaped text.

13280 (yygetLRActions, yyrecoverParseError): Use them.

13283 counted in the token inserted at end of file. Now takes
13284 location_t *, not location_t, so that the location can be
13285 adjusted. All uses changed.

13999 Let nondeterministic skeletons be usable with deterministic
14000 tables.
14001
14002 With the patch, GAWK compiled by GCC without -O2 passes its test
14003 suite using a GLR parser driven by LALR tables. It fails with -O2
14004 because `struct stat' gives two different answers on my machine:
14005 88 (definition of an auto var) and later 96 (memset on this var).
14006 Hence the stack is badly corrumpted. The headers inclusion is to
14007 blame: if I move the awk.h inclusion before GLR's system header
14008 inclusion, the two struct stat have the same size.

14062 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,

14239 The GNU coding standard says CFLAGS and YFLAGS are reserved

16527 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
16528 full stderr, and strip it according to the bison options, instead
16529 of composing the error message from different bits.
16530 This makes it easier to check for several error messages.
16531 Adjust all the invocations.
16532 Add an invocation exercising the error token.
16533 Add an invocation demonstrating a stupid error message.
16534 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
16535 Adjust the tests.
16536 Error message are for stderr, not stdout.

16540 * src/gram.h, src/gram.c (error_token_number): Remove, use
16541 errtoken->number.
16542 * src/reader.c (reader): Don't specify the user token number (2)
16543 for $undefined, as it uselessly prevents using it.
16544 * src/gram.h (token_number_t): Move to...
16545 * src/symtab.h: here.
16546 (state_t.number): Is a token_number_t.
16547 * src/print.c, src/reader.c: Use undeftoken->number instead of
16548 hard coded 2.
16549 (Even though this 2 is not the same as above: the number of the
16550 undeftoken remains being 2, it is its user token number which
16551 might not be 2).
16552 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
16553 `user_token_number_max'.
16554 Output `undef_token_number'.
16555 * data/bison.simple, data/bison.c++: Use them.
16556 Be sure to map invalid yylex return values to
16557 `undef_token_number'. This saves us from gratuitous SEGV.

16576 RITEM. Note that it must be able to code symbol numbers as
16577 positive number, and the negation of rule numbers as negative
16578 numbers.
16579 Adjust all dependencies (pretty many).
16580 * src/reduce.c (rule): Remove this `short *' pointer: use
16581 item_number_t.
16582 * src/system.h (MINSHORT, MAXSHORT): Remove.
16583 Include `limits.h'.
16584 Adjust dependencies to using SHRT_MAX and SHRT_MIN.

16591 500.

16593
16594 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
16595 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
16596 passes, but produces negative #line number, once fixed, GCC is
16597 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
16598 C), it passes.
16599 * src/state.h (state_h): Code input lines on ints, not shorts.

17473 Don't use %option yylineno: it seems that then Flex imagines
17474 REJECT has been used, and therefore it won't reallocate its

17782 these states are automatically computed from the initial state.
17783 (generate_states): Adjust.
17784 * src/print.c: When reporting a rule number to the user, substract
17785 1, so that the axiom rule is rule 0, and the first user rule is 1.
17786 * src/reduce.c: Likewise.

17791 0: `$axiom: START-SYMBOL $'.

17793 number of the states has changed (the final state is no longer
17794 necessarily the last), catch up.

17818 (parse_token_decl): If the token being defined has value `0', it
17819 is the eoftoken.
17820 (packsymbols): No longer hack `tags' to insert `$' by hand.
17821 Be sure to preserve the value of the eoftoken.
17822 (reader): Make sure eoftoken is defined.
17823 Initialize nsyms to 0: now eoftoken is created just like the others.
17824 * src/print.c (print_grammar): Don't special case the eof token.
17825 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
17826 lie anyway, albeit pleasant.

18669 Because useless nonterminals are now kept alive (instead of being

18671 related to them. Hence we need to know their number, and adjust
18672 memory allocations.

18674 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
18675 static.
18676 * src/LR0.c (allocate_itemsets): The memory allocated to
18677 `symbol_count' was used for two different purpose: once to count
18678 the number of occurrences of each symbol, and later reassigned to
18679 `shift_symbol', containing the symbol that can be shifted from a
18680 given state.
18681 Deobfuscate, i.e., allocate, use and free `symbol_count' here
18682 only, and...
18683 (new_itemsets): Allocate `shift_symbol' here.
18684 (allocate_itemsets): symbol_count includes useless nonterminals.

19264 * tests/calc.at, tests/output.at, tests/regression.at,
19265 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
19266 now the tests are run in private dirs, therefore AC_CLEANUP and
19267 family can be simplified to 0-ary.
19268 * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
19269 use abs. path to find config.h.
19270 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
19271 stderr, there can be way too much random noise.
19272 Instead pass -Werror to GCC and rely on the exit status.

19290 Revert a previous patch: these are really const.
19291 * src/conflicts.c (conflict_report): Additional useless pair of
19292 braces to pacify GCC's warnings for `if () if () {} else {}'.
19293 * src/lex.c (parse_percent_token): Replace equal_offset with
19294 arg_offset.
19295 arg is const.
19296 Be sure to strdup `arg' when used, since there is no reason for
19297 token_buffer not to change.

21065 The location tracking mechanism is precious for parse error

21101 Test also `--verbose', `--defines' and `--name-prefix'. Testing
21102 the latter demonstrates a flaw in the handling of non debugging
21103 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
21104 was used in order to simplify:
21105
21106 #if YYDEBUG
21107 if (yydebug)
21108 {
21109 ...

21111 #endif

21113 into
21114
21115 if (yydebug)
21116 {
21117 ...
21118 }
21119

21121 `--name-prefix=foo' is used since it produces `#define yydebug
21122 foodebug'.

21172 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
21173 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
21174 difficult and introduced a lot of core dump. It turns out that
21175 Bison used an implementation of `xmalloc' based on `calloc', and
21176 at various places it does depend upon the initialization to 0. I
21177 have not tried to isolate the pertinent places, and all the former
21178 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

21282 `user_toknums' is output as a `short[]' in `output.c', while it is
21283 defined as a `int[]' in `reader.c'. For consistency with the

22262 New function.
22263 (readgram): Use `#if 0' around code that accepted %command
22264 inside grammar rules: The documentation doesn't allow it,

22266 (parse_token_decl): Extended the %token
22267 declaration to allow a multi-character symbol as an alias.
22268 (parse_thong_decl): New function.

22279 Revised and use multiple warnxxx functions to avoid using VARARGS1.
22280 (read_declarations): Improve the error message for
22281 an invalid character. Do not abort.
22282 (read_declarations, copy_guard, copy_action): Use
22283 printable_version to avoid unprintable characters in printed output.
22284 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
22285 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):

22306 Include getopt.h. Add some extern decls.
22307 (safegetc): New function to deal with EOF gracefully.
22308 (literalchar); new function to deal with reading \ escapes.
22309 (lex): Use literalchar.
22310 (lex): Implemented "..." tokens.
22311 (literalchar, lex, parse_percent_token): Made tokenbuffer
22312 always contain the token. This includes growing the token
22313 buffer while reading an integer.
22314 (parse_percent_token): Replaced if-else statement with percent_table.
22315 (parse_percent_token): Added % declarations as another
22316 way to specify the flags -n, -l, and -r. Also added hooks for
22317 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
22318 major changes to files.c.
22319 (lex) Retain in the incoming stream a character following
22320 an incorrect '/'.
22321 (skip_white_space, lex): Revised most error messages
22322 and changed fatal to warn to avoid aborting.
