1833 * src/lalr.c (state_lookahead_tokens_count): For code readability,
1834 move the check for disabled transitions to an aver since conflict
1835 resolution hasn't happened yet.
1836
1837 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
1838 labels a state as inconsistent just because it has error transitions.
1839 The original form of this check appeared in revision 1.1 of lalr.c,
1840 which was committed on 1991-12-21. Now (at least), changing the
1841 consistency label on such a state appears to have no useful effect in
1842 any of the places it is examined, which I enumerate below. The key
1843 point to understanding each item in this enumeration is that a state
1844 with an error transition is labelled consistent in the first place only
1845 if it has no rules, so the check cannot matter for states that have
1846 rules. (1) Labelling a state as inconsistent will cause set_conflicts
1847 to try to identify its conflicts, and a state must have *rules* to have
1848 conflicts. (2) Labelling a state as inconsistent will affect how
1849 action_row sets the default *rule* for the state. (3) Labelling a
1850 state as inconsistent will cause build_relations to add lookback edges
1851 to *rules* in that state.

1853 more carefully.

2362 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use

2426 params with digraphs.
2427 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
2428 values to the empty string since these are no longer guaranteed
2429 initialized by the front-end.

2491 Instead of having skeletons declare all valid %define variables and
2492 %code qualifiers, provide macros that retrieve the associated values
2493 and build these lists automatically. Thus Bison will now warn when a
2494 variable or qualifier is not used by the skeleton in the current
2495 invocation regardless of whether it might sometimes be used by that
2496 skeleton in other invocations. Also, move all %define value macros to
2497 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
2498 form, which is replaced by %code.
2499 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
2500 (b4_check_user_names): ... this, and change the series of valid name
2501 arguments to a single list argument for names used in the skeleton
2502 similar to the existing list argument for names used in the grammar.
2503 Warn instead of complaining.
2504 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
2505 values and %code code, to format %code code properly, and to build
2506 lists of all %define variables and %code qualifiers used in the
2507 skeleton: b4_skeleton_percent_define_variables and
2508 b4_skeleton_percent_code_qualifiers.

2533 terminology used in bison.m4.

2791 Encapsulate code properties and related functionality for the various
2792 destructors, printers, and actions into a code_props structure and
2793 interface. This patch merely implements code_props in scan-code.h and
2794 scan-code.l. Future patches will rewrite other modules to use it.
2795 Discussed starting at
2796 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
2797 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
2798 consistently initialize const structs that have an empty location
2799 field.
2800 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
2801 to ensure consistency.
2802 * src/scan-code.h (code_props): New structure.
2803 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
2804 function, macro, and const global variable for initializing a
2805 code_props with no code.
2806 (code_props_plain_init, code_props_symbol_action_init,
2807 code_props_rule_action_init, code_props_translate_code): The rest of
2808 the new code_props functional interface. Among other things, the init
2809 functions set the code_props kind field so that
2810 code_props_translate_code will know whether to behave like
2811 translate_symbol_action, translate_rule_action, or translate_code.
2812 These old translate functions must remain until all other modules are
2813 updated to use the new code_props interface.
2814 (code_scanner_last_string_free): New function similar to
2815 gram_scanner_last_string_free.
2816 (code_scanner_free): Add documentation.
2817 * src/scan-code.l: Implement the new interface.
2818 (code_lex): Make it static, add a code_props* argument, and remove the
2819 rule argument.
2820 (last_string): New static global similar to the one in scan-gram.l.
2821 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
2822 instead of rule.
2823 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
2824 code_props since Bison may one day use this information for destructors
2825 and printers.
2826 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
2827 (handle_action_dollar): Use symbol_list_n_get and set used flag
2828 directly since symbol_list_n_used_set is removed.
2829 (translate_action): Add a code_props* argument and remove the rule,
2830 action, and location arguments. Pass the code_props* on to code_lex.
2831 (translate_rule_action, translate_symbol_action, translate_code):
2832 Rewrite as wrappers around the new code_props interface.
2833 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
2834 it would eventually need to break the encapsulation of code_props.

2960 Enable push parsers to operate in impure mode. Thus, %push-parser no

2962 towards being able to test the push parser code by running the entire

3226 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
3227 `bison ', use m4_index instead of m4_substr since chopping up a string
3228 containing M4-special characters causes problems here.
3229
3230 Fix a couple of bugs related to special characters in user-specified
3231 file names, and make it easier for skeletons to compute output file
3232 names with the same file name prefix as Bison-computed output file
3233 names.
3234 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
3235 b4_parser_file_name and b4_spec_defines_file instead of
3236 @output_parser_name@ and @output_header_name@, which are now redundant.
3237 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
3238 b4_parser_file_name, b4_spec_defines_file, and the new
3239 @basename(FILENAME@) instead of @output_parser_name@ and
3240 @output_header_name@, which inappropriately escaped the file names as
3241 C string literals.

3246 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does

3248 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
3249 characters are escaped properly.
3250 * src/output.c (prepare): Define muscle file_name_all_but_ext as
3251 all_but_ext.
3252 For pkgdatadir muscle, maintain previous functionality by using
3253 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
3254 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
3255 digraphs would never be expanded. Hopefully no one has M4-special
3256 characters in his Bison installation path.
3257 * src/scan-skel.l: Don't parse @output_header_name@ and
3258 @output_parser_name@ anymore since they're now redundant.
3259 In @output, use decode_at_digraphs.

3612 all actions have already been scanned in order to set `used' flags.
3613 Otherwise, checking that a midrule's $$ is set will not always work
3614 properly because the midrule check must forward-reference the midrule's

4123 Whether the default %destructor/%printer applies to a particular symbol
4124 isn't a question of whether the user *declares* that symbol (in %token,
4125 for example). It's a question of whether the user by any means
4126 *defines* the symbol at all (by simply using a char token, for
4127 example). $end is defined by Bison whereas any other token with token
4128 number 0 is defined by the user. The error token is always defined by
4129 Bison regardless of whether the user declares it with %token, but we
4130 may one day let the user define error as a nonterminal instead.

4309 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
4310 declare a %destructor for a mid-rule's semantic value. It's just
4311 impossible to declare one specific to it.

4313 code. Describe default %destructor form.

4315 %printer/%destructor declarations.
4316 * src/output.c (symbol_destructors_output): Use symbol_destructor_get

4324 variables to record the default %destructor and %printer.

4348
4349 Make the skeletons consistent in how they pop the end token and invoke
4350 its %destructor.
4351 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
4352 state, which has token number 0, since this would invoke the
4353 %destructor for the end token.
4354 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
4355 until after shifting the end token, or else it won't be popped.
4356 * data/yacc.c (yyparse): Likewise.
4357
4358 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
4359 it's the end token. Upon termination, destroy an unshifted lookahead
4360 even when it's the end token.
4361 * data/lalr1.cc (yy::parser::parse): Likewise.
4362 * data/yacc.c (yyparse): Likewise.
4363
4364 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
4365 value warnings for the end token when the user gives the end token a

4379 rejects them.
4380 Don't use autoreconf; instead, invoke autopoint etc. by hand,
4381 so that we can remove the intl files at a better time.
4382 (intl_files_to_remove): Remove aclocal.m4, since it gets
4383 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
4384 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,

4391 strdup.h.

5191 Also, the embedded comments in this test case claim it checks the case
5192 of an empty RHS that has inherited the initial location. However, the
5193 corresponding LHS was already resolved, so yyresolveLocations didn't
5194 actually have reason to modify it. Fix this by forcing
5195 nondeterministic operation at the beginning of the parse.

5495 the RHS of a semantic option. Document the interface.

5980 destroy the semantic value before returning rather than leaking it.
5981 (yyresolveStates): If a user action cuts the parse and thus
5982 yyresolveValue fails, ignore the (unset) semantic value rather than
5983 corrupting the yyGLRState, and empty the semantic options list since
5984 the user actions should have called all necessary destructors.

6668 Use unlocked I/O for a minor performance improvement on hosts like
6669 GNU/Linux and Solaris that support unlocked I/O. The basic idea

7120 that the byte '\0xff' is not printable in the C locale; it is,
7121 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are

7281 the 2005-04-17 change, which is now accomplished (mostly) via
7282 changes in the parsers as described above.

7289 * tests/cxx-type.at: Don't pipe output of ./types through sed to
7290 remove trailing spaces. This loses the exit status of ./types,
7291 and isn't needed since ./types shouldn't be emitting trailing
7292 spaces.

7354 eases translation.

7376 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
7377 Fix typos in explanations of the runtime file.
7378 * bootstrap: Change gettext keyword from YYI18N to YY_.
7379 Use standard Makefile.in.in in runtime-po, since we'll arrange
7380 for backward-compatible bison-runtime.po files in a different way.
7381 * data/glr.c (YY_): New macro, from yacc.c.
7382 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
7383 Translate messages intended for users.
7384 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
7385 the wording in the other skeletons. We don't know that the memory
7386 is virtual.

7393 Move defn to a more logical place, to be consistent with other
7394 skeletons.

7396 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
7397 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
7398 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
7399 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

7411 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
7412 All uses removed.
7413 (yyStackOverflow): Just longjmp, but with value 2 so that caller
7414 can handle the problem.
7415 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
7416 (yyparse): New local variable yyresult to record the result.
7417 Use result of setjmp to set it, rather than storing itinto
7418 struct.
7419 (yyDone): Remove label.
7420 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
7421 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
7422 if YYABORT is used).
7423 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
7424 yyparse status; put status > 1 into diagnostic.
7425 Check that status==2 works.
7426 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
7427 Use exit status 3 for failure to open (which shouldn't happen).

7431 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
7432 1 on syntax error; just let yyparse do its thing.
7433 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
7434 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
7435 (Exploding the Stack Size with Alloca):
7436 (Exploding the Stack Size with Malloc):
7437 Expect exit status 2, not 1, since the parser is supposed to blow
7438 its stack. Problem reported by twlevo@xs4all.nl.
7439
15f40952
PE
7440 * data/glr.c (yyparse): Don't assume that the initial calls
7441 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
7442 Print a stack-overflow message and fail instead.
7443 Initialize the line-number information before creating the stack,
7444 so that the stack-overflow message can report line zero safely.

a22ff96f
PE
7458 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
7459 test for valgrind; valgrind is independent of g++.
7460 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
7461 for compatibility with POSIX 1003.1-2001 (if running coreutils).
7462 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
7463 Use a destructor, so that we can expand the stack. Change
7464 YYSTYPE to char * so that we can free it. Cast result of malloc.

7577 action does not set yylloc and/or yylval.

7637 the initialization was successful. It might fail if storage was
7638 exhausted.

8195 Remove uses of 'short int' and 'unsigned short int'. This raises
8196 some arbitrary limits. It uses more memory but nowadays that's
8197 not much of an issue.
8198
8199 This change does not affect the generated parsers; that's a different
8200 task, as some users will want to conserve memory there.
8201
8202 Ideally we should use size_t to represent all object counts, and
8203 something like ptrdiff_t to represent signed differences of object

8603 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
8604 whether the reducion was empty or not. This leaves room to
8605 improve the use of YYLLOC_DEFAULT in such a case.
8606 lalr1.cc is still experimental, so changing this is acceptable.
8607 And finally, there are probably not many users who changed the
8608 handling of locations in GLR, so changing is admissible too.

8756 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
8757 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
8758 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
8759 the extra Bison directives instead of the whole series.
8760 Change the grammar so that there are recoverable errors, and
8761 unrecoverable errors. Now we can have the parser give up before
8762 consuming the whole input. As a result we now can observe that
8763 the lookahead is freed when needed.
8764 Change the parser source to parse argv[1] instead of a hard coded
8765 string.
8766 Simplify yylex, and give a value and location to EOF.
8767 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
8768 passed directives already coded in the file.
8769 Add some tests to check the location of "error".
8770 For some tests, the C++ parser is correct, and not yacc.c.
8771 For other tests, they provide different, but unsatisfying, values,
8772 so keep the C++ value so that at least one parser is "correct"
8773 according to the test suite.

8775 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

8953 Spent a few hours checking out which prerequisite versions the
8954 current sources actually require. I went all the way back to
8955 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
8956 a seemingly endless set of combinations of versions more recent
8957 than that. The bottom line is that the current sources require
8958 fairly recent versions of the build tools, and it'll be some work
8959 to change this.

9475 When reducing initial empty rules, Bison parser read an initial
9476 location that is not defined. This results in garbage, and that

9774 The problem was that GLR parsers did not conform to the C standard,
9775 because actions like { $1 = $2 + $3; } expanded to expressions
9776 that invoked YYFILL in separate subexpressions, and YYFILL assigned
9777 to a local variable. The C standard says that expressions
9778 like (var = f ()) + (var = f ()) have undefined behavior.
9779 Another problem was that GCC sometimes issues warnings that
9780 yyfill and its parameters are unused.
9781
9782 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
9783 as possibly unused.
9784 (yyfill): New function.
9785 (YYFILL): Use it.
9786 (yyuserAction): Change type of yynormal to bool, so that it matches
9787 the new yyfill signature. Mark it as possibly unused.

9790 Follow up on a bug I reported in February, where a Bison-generated
9791 parser can loop. Provide a test case and a fix for yacc.c. I
9792 don't have a fix for lalr1.cc or for glr.c, unfortunately.
9793 The original bug report is in:

9796 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
9797 macro's size was becoming unwieldy.
9798 (yyerrlab): Do not discard an empty lookahead symbol, as this
9799 might destroy garbage.
9800 (yyerrorlab): New label, with the old contents of YYERROR,
9801 plus the following change: pop the stack of rhs corresponding
9802 to the production that invoked YYERROR. That is how Yacc
9803 behaves, and POSIX requires this behavior.
9804 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
9805 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
9806 Define 'alarm' to do nothing if unistd.h is not available.
9807 Add a new rule "exp: '-' error;" to test the above change to
9808 data/yacc.c. Use 'alarm' to abort any test taking longer than
9809 10 seconds, as it's probably looping.
9810 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
9811 Also, the new yacc.c generates two fewer diagnostics for an
9812 existing test.

10056 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
10057 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
10058 cursor, instead of leaving it undefined. This fixes a bug

10065 <sys/resource.h> can be included, include sys/time.h and
10066 sys/times.h first, if available. This works around the SunOS

10166 depend on *loc, so that the reader doesn't give the the false
10167 impression that *loc is initialized.
10168 (<INITIAL>"%%"): Do not bother setting code_start, since its value
10169 does not survive the return.

10175 yylex invocation. An alternative would be making it static, but
10176 then it starts with the second %%'s beginning, instead of its end.

10440 we don't need to worry about yyerrlab1 being reported as an
10441 "unused label" by non-GCC C compilers. The downside is that if
10442 locations are used then a couple of statements are duplicated each
10443 time YYERROR is invoked, but the upside is that the warnings
10444 should vanish.
10445 (yyerrlab1): Move code to YERROR.

10463 explicitly, as is the case in yacc.c; it is not a problem, as
10464 these elements have fake values.

10571 Switch back to the Yacc style of conflict reports, undoing some

10573 * doc/bison.texinfo (Understanding): Use Yacc style for
10574 conflict reports. Also, use new way of locating rules.
10575 * src/conflicts.c (conflict_report):
10576 Renamed from conflict_report_yacc, removing the old
10577 'conflict_report'. Translate the entire conflict report at once,
10578 so that we don't assume that "," has the same interpretation in
10579 all languages.
10580 (conflicts_output): Use Yacc-style conflict report for each state,
10581 instead of our more-complicated style.
10582 (conflicts_print): Use Yacc-style conflict report, except print
10583 the input file name when not emulating Yacc.

10601 * data/yacc.c (yyparse): New local var yylerrsp, to record the
10602 top of the location stack's error locations.
10603 (yyerrlab): Set it. When discarding a token, push its location
10604 onto yylerrsp so that we don't lose track of the error's end.
10605 (yyerrlab1): Now is only the target of YYERROR, so that we can
10606 properly record the location of the action that failed. For GCC
10607 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
10608 GCC warning about yyerrlab1 being unused if YYERROR is unused.
10609 (yyerrlab2): New label, which yyerrlab now falls through to.
10610 Compute the error's location by applying YYLLOC_DEFAULT to
10611 the locations of all the symbols that went into the error.
10612 * doc/bison.texinfo (Location Default Action): Mention that
10613 YYLLOC_DEFAULT is also invoked for syntax errors.
10614 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

10673 If the user does not define YYSTYPE as a macro, Bison now declares it
10674 using typedef instead of defining it as a macro. POSIX requires this.
10675 For consistency, YYLTYPE is also declared instead of defined.
10676
10677 %union directives can now have a tag before the `{', e.g., the
10678 directive `%union foo {...}' now generates the C code
10679 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
10680 The default union tag is `YYSTYPE', for compatibility with Solaris 9
10681 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
10682 instead of `yyltype'.
10683
10684 `yystype' and `yyltype' are now obsolescent macros instead of being
10685 typedefs or tags; they are no longer documented and will be
10686 withdrawn in a future release.

10694 for backward compatibility.
10695 * data/yacc.c: Likewise.
10696
10697 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
10698 does not specify a union tag. This is for compatibility with
10699 Solaris 9 yacc.

10720 to return when scanning braced code.

10790 Remove unportable casts and storage allocation tricks.
10791 While we're at it, remove almost all casts, since they
10792 usually aren't needed and are a sign of trouble.
10793
10794 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
10795
10796 * src/derives.c (derives_compute): Do not subtract NTOKENS from
10797 the pointer DSET returned by malloc; this isn't portable.
10798 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
10799 Similarly for DERIVES.
10800 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
10801 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
10802 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
10803
10804 * src/derives.c (derives_compute): Do not bother invoking
10805 int_of_rule_number, since rule numbers are integers.
10806
10807 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
10808 rather than XMALLOC (char, N).
10809
10810 * src/files.c (filename_split): Rewrite to avoid cast.
10811
10812 * src/gram.h (symbol_number_as_item_number,
10813 item_number_as_symbol_number, rule_number_as_item_number,
10814 item_number_as_rule_number):
10815 Now inline functions rather than macros, to avoid casts.
10816 * src/state.h (state_number_as_int): Likewise.
10817 * src/tables.c (state_number_to_vector_number,
10818 symbol_number_to_vector_number): Likewise.

10820 * src/gram.h (int_of_rule_number): Remove; no longer used.
10821
10822 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
10823 since the resulting storage is always stored into.
10824
10825 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
10826 where it's needed.
10827

10834 Likewise.
10835 * src/uniqstr.c (uniqstr_print): Likewise.

10840 symbol_check_alias_consistency_processor, symbol_pack_processor,

10843 * src/uniqstr.c (uniqstr_print_processor): Likewise.
10844 * src/muscle_tab.c (muscles_m4_output):

10848 symbols_token_translations_init):

10850 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
10851
10852 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
10853 var instead of casting to long, to avoid casts.
10854 (prepare_states): Use MALLOC rather than alloca, so that we don't
10855 have to worry about alloca.
10856 * src/state.c (state_hash_lookup): Likewise.
10857
10858 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
10859 local var instead of casting to unsigned char, to avoid casts.
10860
10861 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
10862 STATE_ALLOC): Remove.
10863 (transitions_new, errs_new, reductions_new, state_new): Use malloc
10864 rather than calloc, and use offsetof to avoid allocating slightly
10865 too much storage.
10866 (state_new): Initialize all members.
10867
10868 * src/state.c (state_hash): Use unsigned accumulator, not signed.
10869
10870 * src/symtab.c (symbol_free): Remove; unused.
10871 (symbol_get): Remove cast in lhs of assignment.

10877 (symbols_do): Remove decl; now static.

10881 (<inttypes.>, <stdint.h>): Include if available.
10882 (uintptr_t): New type, if system lacks it.
10883 (CALLOC, MALLOC, REALLOC): New macros.
10884 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
10885 new macros.
10886
10887 * src/tables.c (table_size): Now int, to pacify GCC.
10888 (table_grow, table_ninf_remap): Use signed table size.
10889 (save_row): Don't bother initializing locals when not needed.
10890 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
10891 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
10892
10893 * src/vcg.h: Correct misspellings.
10894
10895 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.

10903 that are reserved by POSIX.
10904

11119 processing of Yacc white space and equivalents here.
11120 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
11121 instead of returning ID immediately, since we need to search for
11122 a subsequent colon.
11123 (<INITIAL>"'", "\""): Save token_start.
11124 (<INITIAL>"%{", "{", "%%"): Save code_start.
11125 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.

11679 Use new @ escapes consistently. Represent brackets with @{ and @}
11680 rather than @<:@ and @:>@, since this works a bit better with dumb
11681 editors like vi. Represent @ with @@, since @ is now consistently
11682 an escape. Use @oline@ and @ofile@ rather than __oline__ and
11683 __ofile__, to avoid unexpected expansions. Similarly, use @output
11684 rather than #output.
11685
11686 * data/c.m4 (b4_copyright): Omit file name from comment, since
11687 the file name could contain "*/".

11731 Use new escapes @{ and @} for [ and ].
11732
11733 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
11734 them with auto vars.
11735 Switch to new escape scheme, where @ is the escape character uniformly.
11736 Abort if a stray escape character is found. Avoid unbounded input
11737 buffer when parsing non-escaped text.

11752 counted in the token inserted at end of file. Now takes
11753 location_t *, not location_t, so that the location can be
11754 adjusted. All uses changed.

12091 The last OS that we could find where this wouldn't work is
12092 SunOS 3.5, and that's too old to worry about now.
12093
12094 * data/glr.c (struct yyltype): Define members even when not

12110 Be consistent about 'bool'; the old code used an enum in one
12111 module and an int in another, and this violates the C standard.

12113 * configure.ac (AC_HEADER_STDBOOL): Add.

12468 Let nondeterministic skeletons be usable with deterministic
12469 tables.
12470
12471 With the patch, GAWK compiled by GCC without -O2 passes its test
12472 suite using a GLR parser driven by LALR tables. It fails with -O2
12473 because `struct stat' gives two different answers on my machine:
12474 88 (definition of an auto var) and later 96 (memset on this var).
12475 Hence the stack is badly corrumpted. The headers inclusion is to
12476 blame: if I move the awk.h inclusion before GLR's system header
12477 inclusion, the two struct stat have the same size.

13052 outside the C locale.

13055 this is a GCC extension and is not portable to other compilers.

13058 Do not include <ctype.h>; no longer needed.

13060 warnings on OpenBSD 3.0).

13063 it's not portable.

13066 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
13067
13068 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
13069 exit status as failure, not just exit status 1. Sun C exits
13070 with status 2 sometimes.

15923 _GNU_SOURCE is not defined by config.h, and therefore strndup was
15924 not visible.

15942 Don't use %option yylineno: it seems that then Flex imagines
15943 REJECT has been used, and therefore it won't reallocate its
15944 buffers (which makes no other sense to me than a bug). It results
15945 in warnings for `unused: yy_flex_realloc'.

16251 these states are automatically computed from the initial state.
16252 (generate_states): Adjust.
16253 * src/print.c: When reporting a rule number to the user, substract
16254 1, so that the axiom rule is rule 0, and the first user rule is 1.
16255 * src/reduce.c: Likewise.

16260 0: `$axiom: START-SYMBOL $'.

16262 number of the states has changed (the final state is no longer
16263 necessarily the last), catch up.

16267 Try to make the use of the eoftoken valid. Given that its value

16270 instead of the 0-sentinel.

16286 * src/reader.c (eoftoken): New.
16287 (parse_token_decl): If the token being defined has value `0', it
16288 is the eoftoken.
16289 (packsymbols): No longer hack `tags' to insert `$' by hand.
16290 Be sure to preserve the value of the eoftoken.
16291 (reader): Make sure eoftoken is defined.
16292 Initialize nsyms to 0: now eoftoken is created just like the others.
16293 * src/print.c (print_grammar): Don't special case the eof token.
16294 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
16295 lie anyway, albeit pleasant.
16296 * tests/calc.at: Exercise error messages with eoftoken.
16297 Change the grammar so that empty input is invalid.

16725 * src/print_graph.c (print_core): Complete the set of items via
16726 closure. The next-to-final and final states are still unsatisfying,
16727 but that's to be addressed elsewhere.
16728 No longer output the rule numbers, but do output the state number.
16729 A single loop for the shifts + gotos is enough, but picked a

17138 Because useless nonterminals are now kept alive (instead of being

17149 given state.

17295 (union yyalloc): New type.
17296 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
17297 an arbitrary restriction on hosts where size_t is wider than int.
17298
17299 (yyparse): Don't dump core if alloca or malloc fails; instead, report
17300 a parser stack overflow. Allocate just one block of memory for all
17301 three stacks, instead of allocating three blocks; this typically is
17302 faster and reduces fragmentation.
17303
17304 Do not limit the number of items in the stack to a value that fits
17305 in 'int', as this is an arbitrary limit on hosts with 64-bit
17306 size_t and 32-bit int.

19534 The location tracking mechanism is precious for parse error
19535 messages. Nevertheless, it is enabled only when `@n' is used in
19536 the grammar, which is a different issue (you can use it in error

19538 be another means to enable it.

19570 Test also `--verbose', `--defines' and `--name-prefix'. Testing
19571 the latter demonstrates a flaw in the handling of non debugging
19572 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
19573 was used in order to simplify:
19574
19575 #if YYDEBUG

19584 if (yydebug)
19585 {
19586 ...
19587 }

19641 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
19642 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
19643 difficult and introduced a lot of core dump. It turns out that
19644 Bison used an implementation of `xmalloc' based on `calloc', and
19645 at various places it does depend upon the initialization to 0. I
19646 have not tried to isolate the pertinent places, and all the former
19647 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

20736 declaration to allow a multi-character symbol as an alias.
20737 (parse_thong_decl): New function.

20748 Revised and use multiple warnxxx functions to avoid using VARARGS1.
20749 (read_declarations): Improve the error message for
20750 an invalid character. Do not abort.

20778 (lex): Use literalchar.
20779 (lex): Implemented "..." tokens.
20780 (literalchar, lex, parse_percent_token): Made tokenbuffer
20781 always contain the token. This includes growing the token
20782 buffer while reading an integer.
20783 (parse_percent_token): Replaced if-else statement with percent_table.
20784 (parse_percent_token): Added % declarations as another
20785 way to specify the flags -n, -l, and -r. Also added hooks for
20786 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
20787 major changes to files.c.
20788 (lex) Retain in the incoming stream a character following
20789 an incorrect '/'.
20790 (skip_white_space, lex): Revised most error messages
