2272008-11-07 Akim Demaille <demaille@gostai.com>
228
229 Add "%define assert" to variants.
230 This is used to help the user catch cases where some value gets
231 ovewritten by a new one. This should not happen, as this will
232 probably leak.
233
234 Unfortunately this uncovered a bug in the C++ parser itself: the
235 lookahead value was not destroyed between two calls to yylex. For
236 instance if the previous lookahead was a std::string, and then an int,
237 then the value of the std::string was correctly taken (i.e., the
238 lookahead was now an empty string), but std::string structure itself
239 was not reclaimed.
240
241 This is now done in variant::build(other&) (which is used to take the
242 value of the lookahead): other is not only stolen from its value, it
243 is also destroyed. This incurs a new performance penalty of a few
244 percent, and union becomes faster again.
245
246 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.
247 (b4_variant_if): New.
248 (variant::built): New.
249 Use it whereever the status of the variant changes.
250 * etc/bench.pl.in: Check the penalty of %define assert.

525 Fuse the three stacks into a single one.
526 In order to make it easy to perform benchmarks to ensure that there are no
527 performance loss, lalr1.cc is forked into lalr1-fusion.cc. Eventually,
528 lalr1-fusion.cc will replace lalr1.cc.
529
530 Meanwhile, to make sure that lalr1-fusion.cc is correctly exercized by the
531 test suite, the user must install a symbolic link from lalr1.cc to it.
532
533 Instead of having three stacks (state, value, location), use a stack
534 of triples. This considerably simplifies the code (and it will be
535 easier not to require locations as currently does the C++ parser),
536 and also gives a 10% speedup according to etc/bench (probably mainly since
537 memory allocation is done once instead of three times).
538
539 Another motivation is to make it easier to destruct properly
540 semantic values: now that they are bound to their state (hence
541 symbol type) it will be easier to call the appropriate destructor.
542
543 These changes should probably benefit the C parser too.

557 Push the state, value, and location at the same time.

560
561 * data/lalr1.cc (parser::yypush_): New.
562 (parser::yynewstate): Change the semantics: instead of arriving to
563 this label when value and location have been pushed, but yystate
564 is to be pushed on the state stack, now the three of them must
565 have been pushed before. yystate still must be the new state.
566 This allows to use yypush_ everywhere instead of individual
567 handling of the stacks.

588 Use variants to support objects as semantic values.
589 This patch was inspired by work by Michiel De Wilde. But he used Boost
590 variants which (i) requires Boost on the user side, (ii) is slow, and
591 (iii) has useless overhead (the parser knows the type of the semantic value
592 there is no reason to duplicate this information as Boost.Variants do).
593
594 This implementation reserves a buffer large enough to store the largest
595 objects. yy::variant implements this buffer. It was implemented with
596 Quentin Hocquet.

2293 * src/lalr.c (state_lookahead_tokens_count): For code readability,
2294 move the check for disabled transitions to an aver since conflict
2295 resolution hasn't happened yet.
2296
2297 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
2298 labels a state as inconsistent just because it has error transitions.
2299 The original form of this check appeared in revision 1.1 of lalr.c,
2300 which was committed on 1991-12-21. Now (at least), changing the
2301 consistency label on such a state appears to have no useful effect in
2302 any of the places it is examined, which I enumerate below. The key
2303 point to understanding each item in this enumeration is that a state
2304 with an error transition is labelled consistent in the first place only
2305 if it has no rules, so the check cannot matter for states that have
2306 rules. (1) Labelling a state as inconsistent will cause set_conflicts
2307 to try to identify its conflicts, and a state must have *rules* to have
2308 conflicts. (2) Labelling a state as inconsistent will affect how
2309 action_row sets the default *rule* for the state. (3) Labelling a
2310 state as inconsistent will cause build_relations to add lookback edges
2311 to *rules* in that state.
2312 * src/state.h (struct state): Word the comment for member consistent
2313 more carefully.

2951 Instead of having skeletons declare all valid %define variables and
2952 %code qualifiers, provide macros that retrieve the associated values
2953 and build these lists automatically. Thus Bison will now warn when a
2954 variable or qualifier is not used by the skeleton in the current
2955 invocation regardless of whether it might sometimes be used by that
2956 skeleton in other invocations. Also, move all %define value macros to

3251 Encapsulate code properties and related functionality for the various
3252 destructors, printers, and actions into a code_props structure and
3253 interface. This patch merely implements code_props in scan-code.h and
3254 scan-code.l. Future patches will rewrite other modules to use it.
3255 Discussed starting at
3256 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
3257 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
3258 consistently initialize const structs that have an empty location
3259 field.
3260 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
3261 to ensure consistency.
3262 * src/scan-code.h (code_props): New structure.
3263 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
3264 function, macro, and const global variable for initializing a
3265 code_props with no code.
3266 (code_props_plain_init, code_props_symbol_action_init,
3267 code_props_rule_action_init, code_props_translate_code): The rest of
3268 the new code_props functional interface. Among other things, the init
3269 functions set the code_props kind field so that
3270 code_props_translate_code will know whether to behave like
3271 translate_symbol_action, translate_rule_action, or translate_code.
3272 These old translate functions must remain until all other modules are
3273 updated to use the new code_props interface.
3274 (code_scanner_last_string_free): New function similar to
3275 gram_scanner_last_string_free.
3276 (code_scanner_free): Add documentation.
3277 * src/scan-code.l: Implement the new interface.
3278 (code_lex): Make it static, add a code_props* argument, and remove the
3279 rule argument.
3280 (last_string): New static global similar to the one in scan-gram.l.
3281 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
3282 instead of rule.
3283 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
3284 code_props since Bison may one day use this information for destructors
3285 and printers.
3286 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
3287 (handle_action_dollar): Use symbol_list_n_get and set used flag
3288 directly since symbol_list_n_used_set is removed.
3289 (translate_action): Add a code_props* argument and remove the rule,
3290 action, and location arguments. Pass the code_props* on to code_lex.
3291 (translate_rule_action, translate_symbol_action, translate_code):
3292 Rewrite as wrappers around the new code_props interface.
3293 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
3294 it would eventually need to break the encapsulation of code_props.

3420 Enable push parsers to operate in impure mode. Thus, %push-parser no
3421 longer implies %pure-parser. The point of this change is to move
3422 towards being able to test the push parser code by running the entire
3423 test suite as if %push-parser had been declared.
3424 * data/push.c (yypush_parse): For impure mode, remove the
3425 yypushed_char, yypushed_val, and yypushed_loc arguments.
3426 Instead, declare these as local variables initialized to the global
3427 yychar, yylval, and yylloc.

3478 initialized (with b4_location_initial_line and
3479 b4_location_initial_column) upon calling yypush_parse. However, that
3480 initialization now overwrites the first token's location;

3686 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
3687 `bison ', use m4_index instead of m4_substr since chopping up a string
3688 containing M4-special characters causes problems here.
3689
3690 Fix a couple of bugs related to special characters in user-specified
3691 file names, and make it easier for skeletons to compute output file
3692 names with the same file name prefix as Bison-computed output file
3693 names.
3694 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
3695 b4_parser_file_name and b4_spec_defines_file instead of
3696 @output_parser_name@ and @output_header_name@, which are now redundant.
3697 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
3698 b4_parser_file_name, b4_spec_defines_file, and the new
3699 @basename(FILENAME@) instead of @output_parser_name@ and
3700 @output_header_name@, which inappropriately escaped the file names as
3701 C string literals.

3709 characters are escaped properly.
3710 * src/output.c (prepare): Define muscle file_name_all_but_ext as
3711 all_but_ext.
3712 For pkgdatadir muscle, maintain previous functionality by using
3713 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
3714 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
3715 digraphs would never be expanded. Hopefully no one has M4-special
3716 characters in his Bison installation path.
3717 * src/scan-skel.l: Don't parse @output_header_name@ and
3718 @output_parser_name@ anymore since they're now redundant.
3719 In @output, use decode_at_digraphs.
3720 Parse a new @basename command that invokes last_component.

3980 Finish implementing --warnings=error, which should not be implied by
3981 --warnings=all (or by its synonyms -W and --warnings without
3982 subarguments).
3983 * src/complain.c (set_warning_issued): New function to report that
3984 warnings are being treated as errors and to record an error if so.
3985 Invoke...

3988 "error - warnings are errors" does not appear above "all - all of the

4072 all actions have already been scanned in order to set `used' flags.
4073 Otherwise, checking that a midrule's $$ is set will not always work
4074 properly because the midrule check must forward-reference the midrule's

4583 Whether the default %destructor/%printer applies to a particular symbol
4584 isn't a question of whether the user *declares* that symbol (in %token,
4585 for example). It's a question of whether the user by any means
4586 *defines* the symbol at all (by simply using a char token, for
4587 example). $end is defined by Bison whereas any other token with token
4588 number 0 is defined by the user. The error token is always defined by
4589 Bison regardless of whether the user declares it with %token, but we
4590 may one day let the user define error as a nonterminal instead.

4759 Enable declaration of default %printer/%destructor. Make the parser
4760 use these for all user-declared grammar symbols for which the user does
4761 not declare a specific %printer/%destructor. Thus, the parser uses it
4762 for token 0 if the user declares it but not if Bison generates it as
4763 $end. Discussed starting at

4769 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
4770 declare a %destructor for a mid-rule's semantic value. It's just
4771 impossible to declare one specific to it.
4772 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
4773 code. Describe default %destructor form.
4774 * src/parse-gram.y (grammar_declaration): Parse default
4775 %printer/%destructor declarations.
4776 * src/output.c (symbol_destructors_output): Use symbol_destructor_get

4809 Make the skeletons consistent in how they pop the end token and invoke

4811 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
4812 state, which has token number 0, since this would invoke the

5646 of that state is guaranteed to be resolved, and that's enough. This
5647 fixes the remaining bug reported by Derek M. Jones in

5651 Also, the embedded comments in this test case claim it checks the case
5652 of an empty RHS that has inherited the initial location. However, the
5653 corresponding LHS was already resolved, so yyresolveLocations didn't
5654 actually have reason to modify it. Fix this by forcing
5655 nondeterministic operation at the beginning of the parse.

6441 (yyresolveStates): If a user action cuts the parse and thus

7128 Use unlocked I/O for a minor performance improvement on hosts like
7129 GNU/Linux and Solaris that support unlocked I/O. The basic idea

7580 that the byte '\0xff' is not printable in the C locale; it is,
7581 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are

7741 the 2005-04-17 change, which is now accomplished (mostly) via
7742 changes in the parsers as described above.

7748 Fix more problems reported by twlevo@xs4all.nl.
7749 * tests/cxx-type.at: Don't pipe output of ./types through sed to
7750 remove trailing spaces. This loses the exit status of ./types,
7751 and isn't needed since ./types shouldn't be emitting trailing
7752 spaces.
7753 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
7754 as the stack isn't valid in that case.

7768
7769 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
7770 to FILE * parameter, not to stderr. This fixes a typo introduced
7771 in the 2005-07-12 change.

7789 * data/lalr1.cc (yyerrlab): Likewise.
7790 * data/glr.c (yyparse): Pop everything off the stack before

7814 eases translation.

7825 can be understood only by someone who can read the
7826 (English-language) source code.
7827
7828 Generate runtime-po/bison-runtime.pot automatically, so that we
7829 don't have to worry about garbage getting in that file. We'll

7836 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
7837 Fix typos in explanations of the runtime file.
7838 * bootstrap: Change gettext keyword from YYI18N to YY_.
7839 Use standard Makefile.in.in in runtime-po, since we'll arrange
7840 for backward-compatible bison-runtime.po files in a different way.
7841 * data/glr.c (YY_): New macro, from yacc.c.
7842 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
7843 Translate messages intended for users.

7845 the wording in the other skeletons. We don't know that the memory
7846 is virtual.

7853 Move defn to a more logical place, to be consistent with other
7854 skeletons.

7856 Don't assume line numbers fit in unsigned int; use unsigned long fmts.

7872 All uses removed.
7873 (yyStackOverflow): Just longjmp, but with value 2 so that caller
7874 can handle the problem.

7878 struct.

7881 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
7882 if YYABORT is used).
7883 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
7884 yyparse status; put status > 1 into diagnostic.

8607 it seems weird to return false on success. Returning true changes
8608 the conventions for yyparse.
8609 Alternatively we could return void and send an exception.

8655 Remove uses of 'short int' and 'unsigned short int'. This raises
8656 some arbitrary limits. It uses more memory but nowadays that's
8657 not much of an issue.
8658
8659 This change does not affect the generated parsers; that's a different
8660 task, as some users will want to conserve memory there.
8661
8662 Ideally we should use size_t to represent all object counts, and

9063 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
9064 whether the reducion was empty or not. This leaves room to
9065 improve the use of YYLLOC_DEFAULT in such a case.
9066 lalr1.cc is still experimental, so changing this is acceptable.
9067 And finally, there are probably not many users who changed the
9068 handling of locations in GLR, so changing is admissible too.

9213 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
9214 Bison directive from the Bison file to the invocation of this
9215 macro, so that these directives are passed to
9216 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
9217 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
9218 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
9219 the extra Bison directives instead of the whole series.
9220 Change the grammar so that there are recoverable errors, and
9221 unrecoverable errors. Now we can have the parser give up before
9222 consuming the whole input. As a result we now can observe that
9223 the lookahead is freed when needed.
9224 Change the parser source to parse argv[1] instead of a hard coded
9225 string.
9226 Simplify yylex, and give a value and location to EOF.
9227 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
9228 passed directives already coded in the file.
9229 Add some tests to check the location of "error".
9230 For some tests, the C++ parser is correct, and not yacc.c.
9231 For other tests, they provide different, but unsatisfying, values,
9232 so keep the C++ value so that at least one parser is "correct"
9233 according to the test suite.
9234 (Actions after errors): Remove, this is subsumed by the
9235 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

9413 Spent a few hours checking out which prerequisite versions the
9414 current sources actually require. I went all the way back to
9415 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
9416 a seemingly endless set of combinations of versions more recent
9417 than that. The bottom line is that the current sources require
9418 fairly recent versions of the build tools, and it'll be some work
9419 to change this.
9420 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
9421 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
9422 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
9423 Add comments explaining why those particular versions are
9424 currently needed.

10232 Fix a GLR parser bug I reported in February; see

26ec81e0

10234 The problem was that GLR parsers did not conform to the C standard,
10235 because actions like { $1 = $2 + $3; } expanded to expressions
10236 that invoked YYFILL in separate subexpressions, and YYFILL assigned
10237 to a local variable. The C standard says that expressions
10238 like (var = f ()) + (var = f ()) have undefined behavior.
10239 Another problem was that GCC sometimes issues warnings that
10240 yyfill and its parameters are unused.
10241
10242 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
10243 as possibly unused.
10244 (yyfill): New function.
10245 (YYFILL): Use it.
10246 (yyuserAction): Change type of yynormal to bool, so that it matches
10247 the new yyfill signature. Mark it as possibly unused.
10248

10250 Follow up on a bug I reported in February, where a Bison-generated
10251 parser can loop. Provide a test case and a fix for yacc.c. I
10252 don't have a fix for lalr1.cc or for glr.c, unfortunately.
10253 The original bug report is in:

10256 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
10257 macro's size was becoming unwieldy.
10258 (yyerrlab): Do not discard an empty lookahead symbol, as this
10259 might destroy garbage.
10260 (yyerrorlab): New label, with the old contents of YYERROR,
10261 plus the following change: pop the stack of rhs corresponding
10262 to the production that invoked YYERROR. That is how Yacc
10263 behaves, and POSIX requires this behavior.
10264 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10265 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10266 Define 'alarm' to do nothing if unistd.h is not available.
10267 Add a new rule "exp: '-' error;" to test the above change to
10268 data/yacc.c. Use 'alarm' to abort any test taking longer than
10269 10 seconds, as it's probably looping.
10270 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
10271 Also, the new yacc.c generates two fewer diagnostics for an
10272 existing test.

10899 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
10900 we don't need to worry about yyerrlab1 being reported as an
10901 "unused label" by non-GCC C compilers. The downside is that if
10902 locations are used then a couple of statements are duplicated each
10903 time YYERROR is invoked, but the upside is that the warnings
10904 should vanish.
10905 (yyerrlab1): Move code to YERROR.
10906 (yyerrlab2): Remove. Change uses back to yyerrlab1.

10920 when the stacks contain one element, as the loop would otherwise
10921 free the last state, and then use the top state (the one we just
10922 popped). This means that the initial elements will not be freed
10923 explicitly, as is the case in yacc.c; it is not a problem, as
10924 these elements have fake values.

11031 Switch back to the Yacc style of conflict reports, undoing some

11033 * doc/bison.texinfo (Understanding): Use Yacc style for
11034 conflict reports. Also, use new way of locating rules.
11035 * src/conflicts.c (conflict_report):
11036 Renamed from conflict_report_yacc, removing the old
11037 'conflict_report'. Translate the entire conflict report at once,
11038 so that we don't assume that "," has the same interpretation in
11039 all languages.
11040 (conflicts_output): Use Yacc-style conflict report for each state,
11041 instead of our more-complicated style.
11042 (conflicts_print): Use Yacc-style conflict report, except print
11043 the input file name when not emulating Yacc.
11044 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
11045 Conflicted Reduction, %expect not enough, %expect too much,

11058 This problem was originally reported by Paul Hilfinger in

11061 * data/yacc.c (yyparse): New local var yylerrsp, to record the
11062 top of the location stack's error locations.
11063 (yyerrlab): Set it. When discarding a token, push its location
11064 onto yylerrsp so that we don't lose track of the error's end.
11065 (yyerrlab1): Now is only the target of YYERROR, so that we can
11066 properly record the location of the action that failed. For GCC
11067 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
11068 GCC warning about yyerrlab1 being unused if YYERROR is unused.
11069 (yyerrlab2): New label, which yyerrlab now falls through to.
11070 Compute the error's location by applying YYLLOC_DEFAULT to
11071 the locations of all the symbols that went into the error.
11072 * doc/bison.texinfo (Location Default Action): Mention that
11073 YYLLOC_DEFAULT is also invoked for syntax errors.
11074 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
11075 Error locations include the locations of all the tokens that were
11076 discarded, not just the last token.

11133 If the user does not define YYSTYPE as a macro, Bison now declares it
11134 using typedef instead of defining it as a macro. POSIX requires this.
11135 For consistency, YYLTYPE is also declared instead of defined.
11136
11137 %union directives can now have a tag before the `{', e.g., the
11138 directive `%union foo {...}' now generates the C code
11139 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
11140 The default union tag is `YYSTYPE', for compatibility with Solaris 9
11141 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
11142 instead of `yyltype'.
11143
11144 `yystype' and `yyltype' are now obsolescent macros instead of being
11145 typedefs or tags; they are no longer documented and will be
11146 withdrawn in a future release.

11152 (YYLTYPE): Renamed from yyltype.
11153 (yyltype, yystype): New (and obsolescent) macros,
11154 for backward compatibility.
11155 * data/yacc.c: Likewise.
11156

11158 does not specify a union tag. This is for compatibility with
11159 Solaris 9 yacc.

11180 to return when scanning braced code.

11213 (YYEMPTY): Parenthesize right hand side, since others use it.
11214 (yyparse): Don't assume that our generated code is the only code
11215 that sets yychar.

11250 Remove unportable casts and storage allocation tricks.
11251 While we're at it, remove almost all casts, since they
11252 usually aren't needed and are a sign of trouble.
11253
11254 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
11255
11256 * src/derives.c (derives_compute): Do not subtract NTOKENS from
11257 the pointer DSET returned by malloc; this isn't portable.
11258 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
11259 Similarly for DERIVES.
11260 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
11261 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
11262 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
11263
11264 * src/derives.c (derives_compute): Do not bother invoking
11265 int_of_rule_number, since rule numbers are integers.
11266
11267 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
11268 rather than XMALLOC (char, N).
11269
11270 * src/files.c (filename_split): Rewrite to avoid cast.
11271
11272 * src/gram.h (symbol_number_as_item_number,
11273 item_number_as_symbol_number, rule_number_as_item_number,
11274 item_number_as_rule_number):
11275 Now inline functions rather than macros, to avoid casts.
11276 * src/state.h (state_number_as_int): Likewise.
11277 * src/tables.c (state_number_to_vector_number,
11278 symbol_number_to_vector_number): Likewise.
11279
11280 * src/gram.h (int_of_rule_number): Remove; no longer used.
11281
11282 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
11283 since the resulting storage is always stored into.
11284
11285 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
11286 where it's needed.
11287
11288 * src/muscle_tab.c (muscle_m4_output):
11289 Now inline. Return bool, not int.
11290 * src/state.c (state_compare): Likewise.
11291 * src/symtab.c (symbol_check_defined,
11292 symbol_check_alias_consistency, symbol_pack, symbol_translation,
11293 hash_compare_symbol, hash_symbol):
11294 Likewise.
11295 * src/uniqstr.c (uniqstr_print): Likewise.
11296 * src/muscle_tab.c (muscle_m4_output_processor):
11297 New function, to avoid casts.
11298 * src/state.c (state_comparator, stage_hasher): Likewise.
11299 * src/symtab.c (symbol_check_defined_processor,
11300 symbol_check_alias_consistency_processor, symbol_pack_processor,
11301 symbol_translation_processor, hash_symbol_comparator,
11302 hash_symbol_hasher): Likewise.
11303 * src/uniqstr.c (uniqstr_print_processor): Likewise.
11304 * src/muscle_tab.c (muscles_m4_output):
11305 Use new functions instead of casting old functions unportably.
11306 * src/state.c (state_hash_new): Likewise.
11307 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
11308 symbols_token_translations_init):
11309 Likewise.
11310 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
11311
11312 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
11313 var instead of casting to long, to avoid casts.
11314 (prepare_states): Use MALLOC rather than alloca, so that we don't
11315 have to worry about alloca.
11316 * src/state.c (state_hash_lookup): Likewise.
11317
11318 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
11319 local var instead of casting to unsigned char, to avoid casts.
11320
11321 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
11322 STATE_ALLOC): Remove.
11323 (transitions_new, errs_new, reductions_new, state_new): Use malloc
11324 rather than calloc, and use offsetof to avoid allocating slightly
11325 too much storage.
11326 (state_new): Initialize all members.
11327
11328 * src/state.c (state_hash): Use unsigned accumulator, not signed.
11329
11330 * src/symtab.c (symbol_free): Remove; unused.
11331 (symbol_get): Remove cast in lhs of assignment.
11332 (symbols_do): Now static. Accept generic arguments, not
11333 hashing-related ones.
11334
11335 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
11336 (symbol_processor): Remove.
11337 (symbols_do): Remove decl; now static.
11338
11339 * src/system.h (alloca): Remove; decl no longer needed.
11340 (<stddef.h>): Include, for offsetof.
11341 (<inttypes.>, <stdint.h>): Include if available.
11342 (uintptr_t): New type, if system lacks it.
11343 (CALLOC, MALLOC, REALLOC): New macros.
11344 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
11345 new macros.
11346
11347 * src/tables.c (table_size): Now int, to pacify GCC.
11348 (table_grow, table_ninf_remap): Use signed table size.
11349 (save_row): Don't bother initializing locals when not needed.
11350 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
11351 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
11352
11353 * src/vcg.h: Correct misspellings.
11354
11355 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
11356
11357
11358 * src/getargs.c (getargs): Don't assume EOF == -1.

11362 Change identifier spellings to avoid collisions with names
11363 that are reserved by POSIX.
11364
11365 Don't use names ending in _t, since POSIX reserves them.
11366 For consistency, remove _e and _s endings -- they're weren't
11367 needed to remove ambiguity. All uses changed.
11368 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
11369 turn was just renamed from struniq_t.
11370 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
11371 which in turn was just renamed from struniq_processor_t.

11445 Don't include <errno.h> in the mainstream code, since it

11511 dependency breakages encountered in this process, as follows:
11512 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".

11579 processing of Yacc white space and equivalents here.
11580 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
11581 instead of returning ID immediately, since we need to search for
11582 a subsequent colon.
11583 (<INITIAL>"'", "\""): Save token_start.
11584 (<INITIAL>"%{", "{", "%%"): Save code_start.
11585 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.

12139 Use new @ escapes consistently. Represent brackets with @{ and @}
12140 rather than @<:@ and @:>@, since this works a bit better with dumb
12141 editors like vi. Represent @ with @@, since @ is now consistently
12142 an escape. Use @oline@ and @ofile@ rather than __oline__ and
12143 __ofile__, to avoid unexpected expansions. Similarly, use @output
12144 rather than #output.
12145
12146 * data/c.m4 (b4_copyright): Omit file name from comment, since
12147 the file name could contain "*/".

12194 them with auto vars.
12195 Switch to new escape scheme, where @ is the escape character uniformly.

12551 The last OS that we could find where this wouldn't work is
12552 SunOS 3.5, and that's too old to worry about now.
12553

12928 Let nondeterministic skeletons be usable with deterministic
12929 tables.
12930
12931 With the patch, GAWK compiled by GCC without -O2 passes its test
12932 suite using a GLR parser driven by LALR tables. It fails with -O2
12933 because `struct stat' gives two different answers on my machine:
12934 88 (definition of an auto var) and later 96 (memset on this var).
12935 Hence the stack is badly corrumpted. The headers inclusion is to
12936 blame: if I move the awk.h inclusion before GLR's system header
12937 inclusion, the two struct stat have the same size.

16750 Be sure to preserve the value of the eoftoken.
16751 (reader): Make sure eoftoken is defined.
16752 Initialize nsyms to 0: now eoftoken is created just like the others.
16753 * src/print.c (print_grammar): Don't special case the eof token.
16754 * src/regression.at: Adjust: `$' has value 0, not -1, which was a

17333 Now that states have a complete set of members, the linked list of

17335 member.

17598 Because useless nonterminals are now kept alive (instead of being

20030 Test also `--verbose', `--defines' and `--name-prefix'. Testing
20031 the latter demonstrates a flaw in the handling of non debugging
20032 parsers introduced by myself on 2000-03-16: `#define yydebug 0'

20034

20101 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
20102 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
20103 difficult and introduced a lot of core dump. It turns out that
20104 Bison used an implementation of `xmalloc' based on `calloc', and
20105 at various places it does depend upon the initialization to 0. I
20106 have not tried to isolate the pertinent places, and all the former

21238 (lex): Use literalchar.
21239 (lex): Implemented "..." tokens.
21240 (literalchar, lex, parse_percent_token): Made tokenbuffer
21241 always contain the token. This includes growing the token
21242 buffer while reading an integer.
21243 (parse_percent_token): Replaced if-else statement with percent_table.
21244 (parse_percent_token): Added % declarations as another
21245 way to specify the flags -n, -l, and -r. Also added hooks for
21246 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
21247 major changes to files.c.
21248 (lex) Retain in the incoming stream a character following
21249 an incorrect '/'.
21250 (skip_white_space, lex): Revised most error messages
