3 Always put auxiliary code files in the same dir as other output files.
4 * src/files.c (compute_file_name_parts): When the user specifies
5 --output but not --file-prefix, extract the directory prefix from the
6 file prefix not from the grammar file name. This affects the location
7 of files like location.hh generated by the C++ skeleton. The includes
8 in the other output files require this fix.
9 * tests/output.at (AT_CHECK_OUTPUT): Automatically create directories
10 for expected output files.
11 (Output files): Add a test for the above.

433 * src/output.c (prepare_symbols): When writing yytname muscles, where
434 symbol names will be encoded in C-string literals, tell quotearg to
435 escape trigraphs. This used to be the default in gnulib.
436 * tests/regression.at (Token definitions): Because of the change in
437 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
438 escapes trigraphs in symbol names. Thus, yytname no longer has
439 trigraphs unnecessarily doubly escaped. Update test case output.
440 Extend test case to be sure Bison's own error messages will no longer
441 have trigraphs in symbol names unnecessarily escaped once.

1568 move the check for disabled transitions to an aver since conflict
1569 resolution hasn't happened yet.
1570
1571 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
1572 labels a state as inconsistent just because it has error transitions.
1573 The original form of this check appeared in revision 1.1 of lalr.c,
1574 which was committed on 1991-12-21. Now (at least), changing the
1575 consistency label on such a state appears to have no useful effect in
1576 any of the places it is examined, which I enumerate below. The key
1577 point to understanding each item in this enumeration is that a state
1578 with an error transition is labelled consistent in the first place only
1579 if it has no rules, so the check cannot matter for states that have
1580 rules. (1) Labelling a state as inconsistent will cause set_conflicts
1581 to try to identify its conflicts, and a state must have *rules* to have
1582 conflicts. (2) Labelling a state as inconsistent will affect how
1583 action_row sets the default *rule* for the state. (3) Labelling a
1584 state as inconsistent will cause build_relations to add lookback edges
1585 to *rules* in that state.

2086 Clean up %define and %code implementation in M4 some. Most
2087 importantly, rename all related macros to be in the b4_percent_define
2088 and b4_percent_code namespaces. Also, complete support for `.' in
2089 %define variable names and %code qualifiers.
2090 * data/bison.m4 (b4_check_user_names): Check for special
2091 "SKELETON-NAMESPACE(name)" macros instead of using two nested
2092 m4_foreach loops.
2093 (b4_get_percent_define, b4_get_percent_code): Rename to...
2094 (b4_percent_define_get, b4_percent_code_get): ... these.
2095 Extend documentation with examples.
2096 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
2097 b4_percent_define_skeleton_variables and
2098 b4_percent_code_skeleton_qualifiers.
2099 Expect any value for the %define variable `foo' to be stored in the
2100 macro named `b4_percent_define(foo)'; expect any %code blocks for the
2101 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
2102 expect any unqualified %code blocks to be stored in a macro named
2103 `b4_percent_code_unqualified'.
2104 Use m4_indir so that %define variable names and %code qualifiers can
2105 contain `.', which is allowed by the grammar parser.
2106 (b4_percent_define_default): New macro to set a default value for a
2107 %define variable.
2108 (m4_wrap): Update wrapped code, and fix some underquoting.
2109 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
2110 Expect grammar uses of %define variables and %code qualifiers to be
2111 defined in b4_percent_define_user_variables and
2112 b4_percent_code_user_qualifiers.
2113 * data/c++.m4: Use b4_percent_define_default rather than
2114 m4_define_default. Fix some underquoting. Skeleton usage of %define
2115 variable define_location_comparison now implies skeleton usage of
2116 %define variable filename_type.

2225 Instead of having skeletons declare all valid %define variables and

2228 variable or qualifier is not used by the skeleton in the current
2229 invocation regardless of whether it might sometimes be used by that
2230 skeleton in other invocations. Also, move all %define value macros to
2231 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
2232 form, which is replaced by %code.
2233 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...

2237 Warn instead of complaining.
2238 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define

2525 Encapsulate code properties and related functionality for the various

2527 interface. This patch merely implements code_props in scan-code.h and
2528 scan-code.l. Future patches will rewrite other modules to use it.
2529 Discussed starting at
2530 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
2531 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
2532 consistently initialize const structs that have an empty location
2533 field.
2534 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
2535 to ensure consistency.
2536 * src/scan-code.h (code_props): New structure.
2537 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
2538 function, macro, and const global variable for initializing a
2539 code_props with no code.
2540 (code_props_plain_init, code_props_symbol_action_init,
2541 code_props_rule_action_init, code_props_translate_code): The rest of
2542 the new code_props functional interface. Among other things, the init
2543 functions set the code_props kind field so that
2544 code_props_translate_code will know whether to behave like
2545 translate_symbol_action, translate_rule_action, or translate_code.
2546 These old translate functions must remain until all other modules are
2547 updated to use the new code_props interface.
2548 (code_scanner_last_string_free): New function similar to
2549 gram_scanner_last_string_free.
2550 (code_scanner_free): Add documentation.
2551 * src/scan-code.l: Implement the new interface.
2552 (code_lex): Make it static, add a code_props* argument, and remove the
2553 rule argument.
2554 (last_string): New static global similar to the one in scan-gram.l.
2555 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
2556 instead of rule.
2557 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
2558 code_props since Bison may one day use this information for destructors
2559 and printers.
2560 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
2561 (handle_action_dollar): Use symbol_list_n_get and set used flag
2562 directly since symbol_list_n_used_set is removed.
2563 (translate_action): Add a code_props* argument and remove the rule,
2564 action, and location arguments. Pass the code_props* on to code_lex.
2565 (translate_rule_action, translate_symbol_action, translate_code):
2566 Rewrite as wrappers around the new code_props interface.

2753 b4_location_initial_column) upon calling yypush_parse. However, that
2754 initialization now overwrites the first token's location;
2755 %initial-action assigning @$ already did the same thing, and both bugs
2756 will be fixed in a later patch.

2761 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
2762 yylsp.
2763 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
2764 yyps->NAME so it can be used in yypush_parse.
2765 (yyparse or yypush_parse): For yypush_parse, don't print the
2766 "Starting parse" diagnostic for invocations after the first.
2767 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
2768 yypush_parse, only do it for the first invocation.
2769 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
2770 initialization to occur in yypush_parse but only on the first
2771 invocation.

2784 Encapsulate the push parser state variables into an M4 macro so the

2786 For push mode, remove yypush_parse's local equivalents of these
2787 variables to eliminate unnecessary copying between the two sets at
2788 run-time. This patch also fixes at least a bug related to multiple

2799 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
2800 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
2801 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
2802 (yyparse or yypush_parse): For yyparse in pull mode, replace local
2803 parser state variable declarations with
2804 b4_declare_parser_state_variables.
2805 Don't initialize parser state variables when calling yypush_parse since
2806 yypstate_new already does that.
2807 Invoke the user's initial action only upon the first yypush_parse
2808 invocation.

2985 all_but_ext.
2986 For pkgdatadir muscle, maintain previous functionality by using
2987 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
2988 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
2989 digraphs would never be expanded. Hopefully no one has M4-special
2990 characters in his Bison installation path.

3149 (code_scanner_free): Instead of invoking
3150 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,

3160 (muscle_find): Return storage instead of value so that
3161 --enable-gcc-warnings doesn't produce warnings that the return discards
3162 const. aver that the value and storage are the same since storage
3163 could potentially be NULL when value is not.

3209 add a new `char *code' member.
3210 ("{...}"): Declare semantic type as code.
3211 * src/scan-code.h (translate_rule_action):
3212 (translate_symbol_action, translate_code, translate_action): Return
3213 `char const *' rather than `char *' since external code should not free
3214 these strings.
3215 * src/scan-code.l: Likewise.
3216 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,

3224 expecting a non-zero exit status sets --leak-check=summary and

3857 Whether the default %destructor/%printer applies to a particular symbol
3858 isn't a question of whether the user *declares* that symbol (in %token,
3859 for example). It's a question of whether the user by any means
3860 *defines* the symbol at all (by simply using a char token, for
3861 example). $end is defined by Bison whereas any other token with token
3862 number 0 is defined by the user. The error token is always defined by
3863 Bison regardless of whether the user declares it with %token, but we
3864 may one day let the user define error as a nonterminal instead.

3904 Redo some of the previous commit: add back the ability to use
3905 non-aliased/undeclared string literals since it might be useful to
3906 those declaring %token-table.
3907 * src/reader.c (check_and_convert_grammar): Undo changes in previous
3908 commit: don't worry about complaints from symbols_pack.
3909 * src/symtab.c (symbol_new, symbol_class_set,
3910 symbol_check_alias_consistency): Undo changes in previous commit: count
3911 each string literal as a new symbol and token, assign it a symbol
3912 number, and don't complain about non-aliased string literals.
3913 (symbols_pack): Since symbol_make_alias still does not decrement symbol
3914 and token counts but does still set aliased tokens to the same number,
3915 symbol_pack_processor now leaves empty slots in the symbols array.
3916 Remove those slots.
3917 * tests/regression.at (Undeclared string literal): Remove test case
3918 added in previous commit since non-aliased string literals are allowed
3919 again.
3920 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
3921 remove unnecessary string literal declarations.
3922 * tests/sets.at (Firsts): Likewise.

3926 Don't allow an undeclared string literal, but allow a string literal to
3927 be used before its declaration.
3928 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
3929 symbols_pack complained.
3930 * src/symtab.c (symbol_new): Don't count a string literal as a new
3931 symbol.
3932 (symbol_class_set): Don't count a string literal as a new token, and
3933 don't assign it a symbol number since symbol_make_alias does that.
3934 (symbol_make_alias): It's not necessary to decrement the symbol and
3935 token counts anymore. Don't assume that an alias declaration occurs
3936 before any uses of the identifier or string, and thus don't assert that
3937 one of them has the highest symbol number so far.
3938 (symbol_check_alias_consistency): Complain if there's a string literal
3939 that wasn't declared as an alias.
3940 (symbols_pack): Bail if symbol_check_alias_consistency failed since
3941 symbol_pack asserts that every token has been assigned a symbol number
3942 although undeclared string literals have not.

3966 alias, check and set its alias's user token number instead of its own,
3967 which is set to indicate the alias. Previously, every occurrence of
3968 the character token in the grammar overwrote that alias indicator with
3969 the character code.

3982 so that translators are warned about them (this also helps

3985 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
3986 function, since it simplifies our code a bit.

3989 rather than -W, so we don't get bogus warnings about sign comparisons.
3990 Add -Wpointer-arith, since that warning is useful (it reports code
3991 that does not conform to C89 and that some compilers reject).

4034 use these for all user-declared grammar symbols for which the user does
4035 not declare a specific %printer/%destructor. Thus, the parser uses it
4036 for token 0 if the user declares it but not if Bison generates it as

4043 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
4044 declare a %destructor for a mid-rule's semantic value. It's just
4045 impossible to declare one specific to it.
4046 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
4047 code. Describe default %destructor form.
4048 * src/parse-gram.y (grammar_declaration): Parse default
4049 %printer/%destructor declarations.
4050 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
4051 and symbol_destructor_location_get rather than accessing the destructor
4052 and destructor_location members of struct symbol.

4062 (default_destructor_set, default_printer_set): New functions to set the
4063 default %destructor and %printer.
4064 * src/symtab.h: Prototype all those new functions.
4065 * tests/actions.at (Default %printer and %destructor): New test to

4067 not called for $end, and that $$ and @$ work correctly.
4068 (Default %printer and %destructor for user-declared end token): New

4070 a user-declared end token.

4114 Don't use autoreconf; instead, invoke autopoint etc. by hand,
4115 so that we can remove the intl files at a better time.

4925 Also, the embedded comments in this test case claim it checks the case

4927 corresponding LHS was already resolved, so yyresolveLocations didn't
4928 actually have reason to modify it. Fix this by forcing
4929 nondeterministic operation at the beginning of the parse.

5714 destroy the semantic value before returning rather than leaking it.
5715 (yyresolveStates): If a user action cuts the parse and thus

6402 Use unlocked I/O for a minor performance improvement on hosts like
6403 GNU/Linux and Solaris that support unlocked I/O. The basic idea

6406 come in an unlocked flavor).

7013 Clarify quoting convention of yytname.
7014 * src/output.c (prepare_symbols): Quote all names. This undoes
7015 the 2005-04-17 change, which is now accomplished (mostly) via
7016 changes in the parsers as described above.
7017 * tests/regression.at (Token definitions, Web2c Actions):

7022 Fix more problems reported by twlevo@xs4all.nl.
7023 * tests/cxx-type.at: Don't pipe output of ./types through sed to
7024 remove trailing spaces. This loses the exit status of ./types,
7025 and isn't needed since ./types shouldn't be emitting trailing
7026 spaces.
7027 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
7028 as the stack isn't valid in that case.
7029
7030 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
7031 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
7032 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
7033 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
7034 is used.

7041 overly-picky compilers that reject 'char *foo = "bar";'.
7042
7043 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
7044 to FILE * parameter, not to stderr. This fixes a typo introduced
7045 in the 2005-07-12 change.

7059 Destructor cleanups and regularization among the three skeletons.
7060 * NEWS: Document the behavior changes.
7061 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
7062 stack before failing, as the cleanup code will do it for us now.
7063 * data/lalr1.cc (yyerrlab): Likewise.
7064 * data/glr.c (yyparse): Pop everything off the stack before
7065 freeing it, so that destructors get called properly.
7066 * data/lalr1.cc (yyreturn): Likewise.
7067 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
7068 This is more consistent.
7069 * doc/bison.texinfo (Destructor Decl): Mention more reasons
7070 why destructors might be called. 1.875 -> 2.1.

7072 Some English-language cleanups for %destructor.

7085 Rename yyoverflowab to yyexhaustedlab.
7086 When memory exhaustion occurs during syntax-error reporting,
7087 report it separately rather than in a single diagnostic; this
7088 eases translation.

7098 msgids; there's little point to having them translated, since they
7099 can be understood only by someone who can read the
7100 (English-language) source code.
7101
7102 Generate runtime-po/bison-runtime.pot automatically, so that we
7103 don't have to worry about garbage getting in that file. We'll
7104 make sure after the next official release that old msgids don't
7105 get lost. See

7107
7108 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
7109 Now auto-generated.
7110 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
7111 Fix typos in explanations of the runtime file.
7112 * bootstrap: Change gettext keyword from YYI18N to YY_.
7113 Use standard Makefile.in.in in runtime-po, since we'll arrange
7114 for backward-compatible bison-runtime.po files in a different way.
7115 * data/glr.c (YY_): New macro, from yacc.c.
7116 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
7117 Translate messages intended for users.
7118 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
7119 the wording in the other skeletons. We don't know that the memory
7120 is virtual.
7121 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
7122 Use same method that yacc.c uses.
7123 Don't translate debugging messages.
7124 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
7125 it doesn't work (yet), and requires C++ expertise to fix.
7126 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
7127 Move defn to a more logical place, to be consistent with other
7128 skeletons.
7129 Don't translate debugging messages.
7130 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
7131 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
7132 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
7133 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

7148 can handle the problem.

7152 struct.
7153 (yyDone): Remove label.
7154 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
7155 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
7156 if YYABORT is used).
7157 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with

7483 conftest*, for benefit of CVS commands run at the same time as
7484 "configure". Add build-aux, since "bootstrap" now creates it and
7485 its subfiles.
7486 * Makefile.cfg (move_if_change): Remove.
7487 * Makefile.maint: Remove the update stuff; we now use "bootstrap".

7509 (create_subpipe): Make sure all the newly-created
7510 file descriptors are > 2, so that diagnostics don't
7511 get sent down them (which might cause Bison to hang, in theory).

7930 some arbitrary limits. It uses more memory but nowadays that's
7931 not much of an issue.

8337 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
8338 whether the reducion was empty or not. This leaves room to
8339 improve the use of YYLLOC_DEFAULT in such a case.
8340 lalr1.cc is still experimental, so changing this is acceptable.
8341 And finally, there are probably not many users who changed the
8342 handling of locations in GLR, so changing is admissible too.

8492 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
8493 the extra Bison directives instead of the whole series.
8494 Change the grammar so that there are recoverable errors, and
8495 unrecoverable errors. Now we can have the parser give up before
8496 consuming the whole input. As a result we now can observe that
8497 the lookahead is freed when needed.
8498 Change the parser source to parse argv[1] instead of a hard coded
8499 string.
8500 Simplify yylex, and give a value and location to EOF.
8501 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
8502 passed directives already coded in the file.
8503 Add some tests to check the location of "error".
8504 For some tests, the C++ parser is correct, and not yacc.c.
8505 For other tests, they provide different, but unsatisfying, values,
8506 so keep the C++ value so that at least one parser is "correct"
8507 according to the test suite.

8687 Spent a few hours checking out which prerequisite versions the
8688 current sources actually require. I went all the way back to
8689 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
8690 a seemingly endless set of combinations of versions more recent
8691 than that. The bottom line is that the current sources require
8692 fairly recent versions of the build tools, and it'll be some work
8693 to change this.

9423 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.

9425 the tests right now.
9426 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
9427 yyerror are declared before use; C99 requires this.

9506 Fix a GLR parser bug I reported in February; see

9508 The problem was that GLR parsers did not conform to the C standard,
9509 because actions like { $1 = $2 + $3; } expanded to expressions
9510 that invoked YYFILL in separate subexpressions, and YYFILL assigned
9511 to a local variable. The C standard says that expressions
9512 like (var = f ()) + (var = f ()) have undefined behavior.
9513 Another problem was that GCC sometimes issues warnings that
9514 yyfill and its parameters are unused.
9515
9516 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
9517 as possibly unused.
9518 (yyfill): New function.
9519 (YYFILL): Use it.
9520 (yyuserAction): Change type of yynormal to bool, so that it matches
9521 the new yyfill signature. Mark it as possibly unused.
9522
9523
9524 Follow up on a bug I reported in February, where a Bison-generated
9525 parser can loop. Provide a test case and a fix for yacc.c. I
9526 don't have a fix for lalr1.cc or for glr.c, unfortunately.
9527 The original bug report is in:

9529
9530 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
9531 macro's size was becoming unwieldy.
9532 (yyerrlab): Do not discard an empty lookahead symbol, as this
9533 might destroy garbage.
9534 (yyerrorlab): New label, with the old contents of YYERROR,
9535 plus the following change: pop the stack of rhs corresponding
9536 to the production that invoked YYERROR. That is how Yacc
9537 behaves, and POSIX requires this behavior.
9538 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
9539 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
9540 Define 'alarm' to do nothing if unistd.h is not available.
9541 Add a new rule "exp: '-' error;" to test the above change to
9542 data/yacc.c. Use 'alarm' to abort any test taking longer than
9543 10 seconds, as it's probably looping.
9544 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
9545 Also, the new yacc.c generates two fewer diagnostics for an
9546 existing test.

9550 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
9551 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
9552 This fixes a problem reported by John Bowman when the Compaq/HP
9553 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM

10198 these elements have fake values.

10337 (yyerrlab): Set it. When discarding a token, push its location
10338 onto yylerrsp so that we don't lose track of the error's end.
10339 (yyerrlab1): Now is only the target of YYERROR, so that we can
10340 properly record the location of the action that failed. For GCC
10341 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
10342 GCC warning about yyerrlab1 being unused if YYERROR is unused.
10343 (yyerrlab2): New label, which yyerrlab now falls through to.
10344 Compute the error's location by applying YYLLOC_DEFAULT to
10345 the locations of all the symbols that went into the error.
10346 * doc/bison.texinfo (Location Default Action): Mention that
10347 YYLLOC_DEFAULT is also invoked for syntax errors.
10348 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

10398
10399 * Makefile.maint (cvs-update): Don't assume that the shell
10400 supports $(...), as Solaris sh doesn't.
10401
10402 * src/parse-gram.y (lloc_default): Remove test for empty
10403 nonterminals at the end, since it didn't change the result.

10407 If the user does not define YYSTYPE as a macro, Bison now declares it
10408 using typedef instead of defining it as a macro. POSIX requires this.
10409 For consistency, YYLTYPE is also declared instead of defined.
10410
10411 %union directives can now have a tag before the `{', e.g., the
10412 directive `%union foo {...}' now generates the C code
10413 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
10414 The default union tag is `YYSTYPE', for compatibility with Solaris 9
10415 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
10416 instead of `yyltype'.
10417
10418 `yystype' and `yyltype' are now obsolescent macros instead of being
10419 typedefs or tags; they are no longer documented and will be
10420 withdrawn in a future release.
10421
10422 * data/glr.c (b4_location_type): Remove.
10423 (YYSTYPE): Renamed from yystype.
10424 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
10425 (struct YYLTYPE): Renamed from struct yyltype.
10426 (YYLTYPE): Renamed from yyltype.
10427 (yyltype, yystype): New (and obsolescent) macros,
10428 for backward compatibility.
10429 * data/yacc.c: Likewise.
10430
10431 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
10432 does not specify a union tag. This is for compatibility with
10433 Solaris 9 yacc.
10434
10435 * src/parse-gram.y (add_param): 2nd arg is now char * not char
10436 const *, since it is now modified by stripping surrounding { }.
10437 (current_braced_code): Remove.
10438 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
10439 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
10440 trailing " {...}". Now of type <chars>.
10441 (grammar_declaration): Adjust to bundled tokens.
10442 (code_content): Remove; stripping is now done by add_param.
10443 (print_token_value): Print contents of bundled tokens.
10444 (token_name): New function.
10445
10446 * src/reader.h (braced_code, current_braced_code): Remove.
10447 (token_name): New decl.
10448
10449 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
10450 token_type, not braced_code code_kind. All uses changed.
10451 (SC_PRE_CODE): New state, for scanning after a keyword that
10452 has (or usually has) an immediately-following braced code.
10453 (token_type): New local var, to keep track of which token type
10454 to return when scanning braced code.

PE
10457 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
10458 instead of returning a token type immediately.
10459 (<INITIAL>"{"): Set token type.
10460 (<SC_BRACED_CODE>"}"): Use it.
10461 (handle_action_dollar, handle_action_at): Now returns bool
10462 indicating success. Fail if ! current_rule; this prevents a core dump.
10463 (handle_symbol_code_dollar, handle_symbol_code_at):
10464 Remove; merge body into caller.
10465 (handle_dollar, handle_at): Complain in invalid contexts.
10466

10478 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
10479 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
10480 lookahead symbol, and which sets yychar in parser actions) and it

10486 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
10487 (YYEMPTY): Parenthesize right hand side, since others use it.
10488 (yyparse): Don't assume that our generated code is the only code
10489 that sets yychar.

10523
10524 Remove unportable casts and storage allocation tricks.
10525 While we're at it, remove almost all casts, since they
10526 usually aren't needed and are a sign of trouble.
10527
10528 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
10529
10530 * src/derives.c (derives_compute): Do not subtract NTOKENS from
10531 the pointer DSET returned by malloc; this isn't portable.
10532 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
10533 Similarly for DERIVES.
10534 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
10535 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
10536 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
10537
10538 * src/derives.c (derives_compute): Do not bother invoking
10539 int_of_rule_number, since rule numbers are integers.
10540
10541 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
10542 rather than XMALLOC (char, N).
10543
10544 * src/files.c (filename_split): Rewrite to avoid cast.
10545
10546 * src/gram.h (symbol_number_as_item_number,
10547 item_number_as_symbol_number, rule_number_as_item_number,
10548 item_number_as_rule_number):
10549 Now inline functions rather than macros, to avoid casts.
10550 * src/state.h (state_number_as_int): Likewise.
10551 * src/tables.c (state_number_to_vector_number,
10552 symbol_number_to_vector_number): Likewise.
10553
10554 * src/gram.h (int_of_rule_number): Remove; no longer used.
10555
10556 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
10557 since the resulting storage is always stored into.
10558
10559 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
10560 where it's needed.
10561
10562 * src/muscle_tab.c (muscle_m4_output):
10563 Now inline. Return bool, not int.
10564 * src/state.c (state_compare): Likewise.

10568 Likewise.
10569 * src/uniqstr.c (uniqstr_print): Likewise.
10570 * src/muscle_tab.c (muscle_m4_output_processor):
10571 New function, to avoid casts.
10572 * src/state.c (state_comparator, stage_hasher): Likewise.
10573 * src/symtab.c (symbol_check_defined_processor,
10574 symbol_check_alias_consistency_processor, symbol_pack_processor,
10575 symbol_translation_processor, hash_symbol_comparator,
10576 hash_symbol_hasher): Likewise.
10577 * src/uniqstr.c (uniqstr_print_processor): Likewise.
10578 * src/muscle_tab.c (muscles_m4_output):
10579 Use new functions instead of casting old functions unportably.
10580 * src/state.c (state_hash_new): Likewise.
10581 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
10582 symbols_token_translations_init):
10583 Likewise.
10584 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
10585
10586 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
10587 var instead of casting to long, to avoid casts.
10588 (prepare_states): Use MALLOC rather than alloca, so that we don't
10589 have to worry about alloca.
10590 * src/state.c (state_hash_lookup): Likewise.
10591
10592 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
10593 local var instead of casting to unsigned char, to avoid casts.
10594
10595 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
10596 STATE_ALLOC): Remove.
10597 (transitions_new, errs_new, reductions_new, state_new): Use malloc
10598 rather than calloc, and use offsetof to avoid allocating slightly
10599 too much storage.
10600 (state_new): Initialize all members.
10601
10602 * src/state.c (state_hash): Use unsigned accumulator, not signed.
10603
10604 * src/symtab.c (symbol_free): Remove; unused.
10605 (symbol_get): Remove cast in lhs of assignment.
10606 (symbols_do): Now static. Accept generic arguments, not
10607 hashing-related ones.
10608
10609 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
10610 (symbol_processor): Remove.
10611 (symbols_do): Remove decl; now static.

10615 (<inttypes.>, <stdint.h>): Include if available.
10616 (uintptr_t): New type, if system lacks it.
10617 (CALLOC, MALLOC, REALLOC): New macros.
10618 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
10619 new macros.
10620
10621 * src/tables.c (table_size): Now int, to pacify GCC.
10622 (table_grow, table_ninf_remap): Use signed table size.
10623 (save_row): Don't bother initializing locals when not needed.
10624 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
10625 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
10626
10627 * src/vcg.h: Correct misspellings.
10628
10629 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.

10636 Change identifier spellings to avoid collisions with names
10637 that are reserved by POSIX.
10638
10639 Don't use names ending in _t, since POSIX reserves them.
10640 For consistency, remove _e and _s endings -- they're weren't
10641 needed to remove ambiguity. All uses changed.
10642 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
10643 turn was just renamed from struniq_t.

10645 which in turn was just renamed from struniq_processor_t.

10856 a subsequent colon.
10857 (<INITIAL>"'", "\""): Save token_start.

10859 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.

11166 "$CC -E foo.h" is allowed, as this doesn't work with the Portland

11171 backslash-newline tests with "#if 0", to make it less likely that
11172 we'll run into compiler bugs. Bring back solitary \ inside
11173 comment, but add a closing comment to work around HP C bug. Don't

11416 an escape. Use @oline@ and @ofile@ rather than __oline__ and

12202 Let nondeterministic skeletons be usable with deterministic
12203 tables.
12204
12205 With the patch, GAWK compiled by GCC without -O2 passes its test
12206 suite using a GLR parser driven by LALR tables. It fails with -O2
12207 because `struct stat' gives two different answers on my machine:
12208 88 (definition of an auto var) and later 96 (memset on this var).
12209 Hence the stack is badly corrumpted. The headers inclusion is to
12210 blame: if I move the awk.h inclusion before GLR's system header
12211 inclusion, the two struct stat have the same size.

12265 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
12266 because the Bison parser reads the second action before reducing
12267 the first one.
12268 * src/scan-gram.l (rule_length): New static var.
12269 Use it to keep track of the rule length in the scanner, since
12270 we can't expect the parser to be in lock-step sync with the scanner.
12271 (handle_action_dollar, handle_action_at): Use this var.
12272 * tests/actions.at (Exotic Dollars): Test for the problem.

12369 type enum_bitset_opts, to conform to the C Standard, and similarly
12370 for enum_bitset_type.

12373
12374 Do not use "struct bitset_struct" to mean different things in
12375 different modules. Not only is this confusing, it violates
12376 the C Standard, which requires that structure types in different
12377 modules must be compatible if one is to be passed to the other.
12378 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
12379 All instances of "struct bitset_struct *" replaced with "bitset".

12394 Do not call a function of type T using a call that assumes the
12395 function is of a different type U. Standard C requires that a
12396 function must be called with a type that is compatible with its
12397 definition.
12398 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
12399 New decls.

12783 to minimize the number of warnings from xgettext.
12784 (handle_action_dollar, handle_action_at): Don't use isdigit,

12786 outside the C locale.
12787
12788 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
12789 this is a GCC extension and is not portable to other compilers.

12792 Do not include <ctype.h>; no longer needed.

12794 warnings on OpenBSD 3.0).
12795

12797 it's not portable.

12801
12802 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
12803 exit status as failure, not just exit status 1. Sun C exits
12804 with status 2 sometimes.

15401 that.
15402 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
15403 file will be used.
15404 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
15405 (prepare): Given that for the time being changesyntax is not
15406 usable in M4, rename the muscles using `-' to `_'.
15407 Define `defines_flag', `output_parser_name' and `output_header_name'.
15408 * src/output.h (actions_output, guards_output)
15409 (token_definitions_output): Adjust prototypes.

15411 processes the output of m4: `__oline__' and `#output'.

15985 these states are automatically computed from the initial state.
15986 (generate_states): Adjust.
15987 * src/print.c: When reporting a rule number to the user, substract
15988 1, so that the axiom rule is rule 0, and the first user rule is 1.
15989 * src/reduce.c: Likewise.
15990 * src/print_graph.c (print_core): For the time being, just as for
15991 the report, depend upon --trace-flags to dump the full set of

15993 * src/reader.c (readgram): Once the grammar read, insert the rule
15994 0: `$axiom: START-SYMBOL $'.
15995 * tests/set.at: Adjust: rule 0 is now displayed, and since the
15996 number of the states has changed (the final state is no longer
15997 necessarily the last), catch up.

16021 (parse_token_decl): If the token being defined has value `0', it
16022 is the eoftoken.
16023 (packsymbols): No longer hack `tags' to insert `$' by hand.
16024 Be sure to preserve the value of the eoftoken.
16025 (reader): Make sure eoftoken is defined.
16026 Initialize nsyms to 0: now eoftoken is created just like the others.
16027 * src/print.c (print_grammar): Don't special case the eof token.
16028 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
16029 lie anyway, albeit pleasant.
16030 * tests/calc.at: Exercise error messages with eoftoken.
16031 Change the grammar so that empty input is invalid.

16123 the switch/case/break flesh.
16124 Don't parse the user action that might follow the guard, let...
16125 (readgram): do it, i.e., now, there can be an action after a

17034 a parser stack overflow. Allocate just one block of memory for all
17035 three stacks, instead of allocating three blocks; this typically is
17036 faster and reduces fragmentation.

19304 Test also `--verbose', `--defines' and `--name-prefix'. Testing
19305 the latter demonstrates a flaw in the handling of non debugging
19306 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
19307 was used in order to simplify:
19308
19309 #if YYDEBUG
19310 if (yydebug)
19311 {
19312 ...
19313 }
19314 #endif
19315
19316 into
19317
19318 if (yydebug)
19319 {
19320 ...
19321 }
19322
19323 unfortunately this leads to a CPP conflict when
19324 `--name-prefix=foo' is used since it produces `#define yydebug
19325 foodebug'.

19375 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
19376 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
19377 difficult and introduced a lot of core dump. It turns out that
19378 Bison used an implementation of `xmalloc' based on `calloc', and
19379 at various places it does depend upon the initialization to 0. I
19380 have not tried to isolate the pertinent places, and all the former
19381 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
19382 someone should address this issue.

19752 Change the handling of @s so that they behave exactly like $s.
19753 There is now a pseudo variable @$ (readble and writable), location
19754 of the lhs of the rule (by default ranging from the location of
19755 the first symbol of the rhs, to the location of the last symbol,
19756 or, if the rhs is empty, YYLLOC).

19762 (after the $): No longer change `*YYLSP', just stack YYLOC the
19763 same way you stack YYVAL.
19764 * src/reader.c (read_declarations): Use warns.
19765 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

20519 way to specify the flags -n, -l, and -r. Also added hooks for
