1102 * src/lalr.c (state_lookahead_tokens_count): For code readability,
1103 move the check for disabled transitions to an aver since conflict
1104 resolution hasn't happened yet.
1105
1106 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
1107 labels a state as inconsistent just because it has error transitions.
1108 The original form of this check appeared in revision 1.1 of lalr.c,
1109 which was committed on 1991-12-21. Now (at least), changing the
1110 consistency label on such a state appears to have no useful effect in
1111 any of the places it is examined, which I enumerate below. The key
1112 point to understanding each item in this enumeration is that a state
1113 with an error transition is labelled consistent in the first place only
1114 if it has no rules, so the check cannot matter for states that have
1115 rules. (1) Labelling a state as inconsistent will cause set_conflicts
1116 to try to identify its conflicts, and a state must have *rules* to have
1117 conflicts. (2) Labelling a state as inconsistent will affect how
1118 action_row sets the default *rule* for the state. (3) Labelling a
1119 state as inconsistent will cause build_relations to add lookback edges
1120 to *rules* in that state.

1621 Clean up %define and %code implementation in M4 some. Most
1622 importantly, rename all related macros to be in the b4_percent_define
1623 and b4_percent_code namespaces. Also, complete support for `.' in
1624 %define variable names and %code qualifiers.
1625 * data/bison.m4 (b4_check_user_names): Check for special
1626 "SKELETON-NAMESPACE(name)" macros instead of using two nested
1627 m4_foreach loops.
1628 (b4_get_percent_define, b4_get_percent_code): Rename to...
1629 (b4_percent_define_get, b4_percent_code_get): ... these.
1630 Extend documentation with examples.
1631 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
1632 b4_percent_define_skeleton_variables and
1633 b4_percent_code_skeleton_qualifiers.
1634 Expect any value for the %define variable `foo' to be stored in the
1635 macro named `b4_percent_define(foo)'; expect any %code blocks for the
1636 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
1637 expect any unqualified %code blocks to be stored in a macro named
1638 `b4_percent_code_unqualified'.
1639 Use m4_indir so that %define variable names and %code qualifiers can
1640 contain `.', which is allowed by the grammar parser.
1641 (b4_percent_define_default): New macro to set a default value for a
1642 %define variable.
1643 (m4_wrap): Update wrapped code, and fix some underquoting.
1644 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
1645 Expect grammar uses of %define variables and %code qualifiers to be
1646 defined in b4_percent_define_user_variables and
1647 b4_percent_code_user_qualifiers.
1648 * data/c++.m4: Use b4_percent_define_default rather than
1649 m4_define_default. Fix some underquoting. Skeleton usage of %define
1650 variable define_location_comparison now implies skeleton usage of
1651 %define variable filename_type.
1652 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
1653 data/push.c, data/yacc.c: Update macro names.

1713 obstacks.

1760 Instead of having skeletons declare all valid %define variables and
1761 %code qualifiers, provide macros that retrieve the associated values
1762 and build these lists automatically. Thus Bison will now warn when a
1763 variable or qualifier is not used by the skeleton in the current
1764 invocation regardless of whether it might sometimes be used by that
1765 skeleton in other invocations. Also, move all %define value macros to
1766 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
1767 form, which is replaced by %code.
1768 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
1769 (b4_check_user_names): ... this, and change the series of valid name
1770 arguments to a single list argument for names used in the skeleton
1771 similar to the existing list argument for names used in the grammar.
1772 Warn instead of complaining.
1773 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
1774 values and %code code, to format %code code properly, and to build
1775 lists of all %define variables and %code qualifiers used in the
1776 skeleton: b4_skeleton_percent_define_variables and
1777 b4_skeleton_percent_code_qualifiers.

1781 the skeleton names lists can finish building first. In place of
1782 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
1783 expect the lists b4_user_percent_define_variables and
1784 b4_user_percent_code_qualifiers.

1786 b4_location_type, b4_filename_type, b4_namespace, and
1787 b4_define_location_comparison, update their names to the
1788 b4_percent_define_ namespace.
1789 * data/glr.c: Don't use b4_check_percent_define_variables and
1790 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
1791 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.

1799 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
1800 Rename to...
1801 (muscle_grow_user_name_list): ... this for consistency with the
1802 terminology used in bison.m4.
1803 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
1804 %define variable names, and rename muscle used_percent_define_variables
1805 to user_percent_define_variables.
1806 (grammar_declaration): Rename muscle used_percent_code_qualifiers to

1808 (content): Remove.

1828 * data/push.c, data/yacc.c: Declare no valid %define variables.
1829 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
1830 similar to muscle_find, but it works even when the muscle stores a
1831 const value.
1832 (muscle_grow_used_name_list): New function for constructing the used
1833 name list muscles that b4_check_for_unrecognized_names requires.
1834 * src/parse-gram.y (prologue_declaration): Warn if a variable is

2062 interface. This patch merely implements code_props in scan-code.h and
2063 scan-code.l. Future patches will rewrite other modules to use it.
2064 Discussed starting at
2065 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.

2068 field.

2074 code_props with no code.
2075 (code_props_plain_init, code_props_symbol_action_init,
2076 code_props_rule_action_init, code_props_translate_code): The rest of
2077 the new code_props functional interface. Among other things, the init
2078 functions set the code_props kind field so that
2079 code_props_translate_code will know whether to behave like
2080 translate_symbol_action, translate_rule_action, or translate_code.
2081 These old translate functions must remain until all other modules are

2090 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
2091 instead of rule.
2092 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
2093 code_props since Bison may one day use this information for destructors
2094 and printers.
2095 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.

2097 directly since symbol_list_n_used_set is removed.

2496 `bison ', use m4_index instead of m4_substr since chopping up a string

2498
2499 Fix a couple of bugs related to special characters in user-specified

2501 names with the same file name prefix as Bison-computed output file
2502 names.

2504 b4_parser_file_name and b4_spec_defines_file instead of
2505 @output_parser_name@ and @output_header_name@, which are now redundant.
2506 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
2507 b4_parser_file_name, b4_spec_defines_file, and the new
2508 @basename(FILENAME@) instead of @output_parser_name@ and
2509 @output_header_name@, which inappropriately escaped the file names as

2518 characters are escaped properly.
2519 * src/output.c (prepare): Define muscle file_name_all_but_ext as
2520 all_but_ext.
2521 For pkgdatadir muscle, maintain previous functionality by using
2522 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
2523 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
2524 digraphs would never be expanded. Hopefully no one has M4-special
2525 characters in his Bison installation path.
2526 * src/scan-skel.l: Don't parse @output_header_name@ and

3392 Whether the default %destructor/%printer applies to a particular symbol
3393 isn't a question of whether the user *declares* that symbol (in %token,
3394 for example). It's a question of whether the user by any means
3395 *defines* the symbol at all (by simply using a char token, for
3396 example). $end is defined by Bison whereas any other token with token
3397 number 0 is defined by the user. The error token is always defined by
3398 Bison regardless of whether the user declares it with %token, but we
3399 may one day let the user define error as a nonterminal instead.

3501 alias, check and set its alias's user token number instead of its own,
3502 which is set to indicate the alias. Previously, every occurrence of
3503 the character token in the grammar overwrote that alias indicator with

3579 declare a %destructor for a mid-rule's semantic value. It's just
3580 impossible to declare one specific to it.

3918 warnings about types for $$, $n, @$, and @n can't be reported yet.

3920 all symbol declarations have been parsed.
3921 * src/scan-code.l (handle_action_dollar): Now that this is invoked
3922 after parsing the entire grammar file, the symbol list here in the case
3923 of a midrule is actually the midrule's empty RHS, so reference its
3924 parent rule's RHS where necessary.
3925 On the other hand, now that you can already know it's a midrule, you

4460 Also, the embedded comments in this test case claim it checks the case

4462 corresponding LHS was already resolved, so yyresolveLocations didn't
4463 actually have reason to modify it. Fix this by forcing
4464 nondeterministic operation at the beginning of the parse.

5210 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
5211 appropriately during nondeterministic operation.
5212 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
5213 members to store the current lookahead to be used by the deferred
5214 user action.
5215 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack

5218 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
5219 yyaddDeferredAction.
5220 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
5221 members of yySemanticOption before invoking yyuserAction, and then set

5226 titles for consistency.

5247 * data/glr.c (yyresolveValue): When merging semantic options, if at
5248 least one user action succeeds but a later one cuts the parse, then
5249 destroy the semantic value before returning rather than leaking it.
5250 (yyresolveStates): If a user action cuts the parse and thus
5251 yyresolveValue fails, ignore the (unset) semantic value rather than
5252 corrupting the yyGLRState, and empty the semantic options list since
5253 the user actions should have called all necessary destructors.

6601 * data/lalr1.cc (yyreturn): Likewise.
6602 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
6603 This is more consistent.

6607 Some English-language cleanups for %destructor.

6620 Rename yyoverflowab to yyexhaustedlab.
6621 When memory exhaustion occurs during syntax-error reporting,

6631 Add i18n support to the GLR skeleton. Partially fix the C++
6632 skeleton; a C++ expert needs to finish this. Remove debugging
6633 msgids; there's little point to having them translated, since they
6634 can be understood only by someone who can read the
6635 (English-language) source code.
6636
6637 Generate runtime-po/bison-runtime.pot automatically, so that we
6638 don't have to worry about garbage getting in that file. We'll
6639 make sure after the next official release that old msgids don't
6640 get lost. See

6646 Fix typos in explanations of the runtime file.

6648 Use standard Makefile.in.in in runtime-po, since we'll arrange
6649 for backward-compatible bison-runtime.po files in a different way.
6650 * data/glr.c (YY_): New macro, from yacc.c.
6651 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
6652 Translate messages intended for users.
6653 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
6654 the wording in the other skeletons. We don't know that the memory
6655 is virtual.

6657 Use same method that yacc.c uses.
6658 Don't translate debugging messages.

6660 it doesn't work (yet), and requires C++ expertise to fix.

6662 Move defn to a more logical place, to be consistent with other
6663 skeletons.
6664 Don't translate debugging messages.
6665 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
6666 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
6667 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.

6687 struct.
6688 (yyDone): Remove label.

6691 if YYABORT is used).

7016 Various maintainer cleanups.
7017 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
7018 conftest*, for benefit of CVS commands run at the same time as
7019 "configure". Add build-aux, since "bootstrap" now creates it and
7020 its subfiles.
7021 * Makefile.cfg (move_if_change): Remove.
7022 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
7023 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

7042 fopen-safer.c, stdio-safer.h, unistd-safer.h.
7043 * lib/subpipe.c: Include "unistd-safer.h".
7044 (create_subpipe): Make sure all the newly-created
7045 file descriptors are > 2, so that diagnostics don't
7046 get sent down them (which might cause Bison to hang, in theory).
7047 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.

7464 Remove uses of 'short int' and 'unsigned short int'. This raises
7465 some arbitrary limits. It uses more memory but nowadays that's
7466 not much of an issue.

7468 This change does not affect the generated parsers; that's a different
7469 task, as some users will want to conserve memory there.

7471 Ideally we should use size_t to represent all object counts, and

7872 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
7873 whether the reducion was empty or not. This leaves room to
7874 improve the use of YYLLOC_DEFAULT in such a case.
7875 lalr1.cc is still experimental, so changing this is acceptable.
7876 And finally, there are probably not many users who changed the
7877 handling of locations in GLR, so changing is admissible too.

8025 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
8026 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
8027 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
8028 the extra Bison directives instead of the whole series.
8029 Change the grammar so that there are recoverable errors, and
8030 unrecoverable errors. Now we can have the parser give up before
8031 consuming the whole input. As a result we now can observe that
8032 the lookahead is freed when needed.
8033 Change the parser source to parse argv[1] instead of a hard coded
8034 string.
8035 Simplify yylex, and give a value and location to EOF.
8036 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
8037 passed directives already coded in the file.
8038 Add some tests to check the location of "error".
8039 For some tests, the C++ parser is correct, and not yacc.c.
8040 For other tests, they provide different, but unsatisfying, values,
8041 so keep the C++ value so that at least one parser is "correct"
8042 according to the test suite.

8222 Spent a few hours checking out which prerequisite versions the
8223 current sources actually require. I went all the way back to
8224 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
8225 a seemingly endless set of combinations of versions more recent
8226 than that. The bottom line is that the current sources require
8227 fairly recent versions of the build tools, and it'll be some work
8228 to change this.
8229 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.

8900 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
8901 Don't use 'index' in comments, as it's a builtin fn on some hosts.
8902 * lib/bitset_stats.c: Include gettext.h unconditionally, as
8903 per recent gettext manual's suggestion.
8904 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):

8928
8929 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
8930 `How Can I Reset @code{yyparse}', since texinfo does not allow
8931 arbitrary @ in node names.

8933 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
8934 shouldn't be needed according to the gettext 0.12.1 documentation

8960 the tests right now.

9041 Fix a GLR parser bug I reported in February; see
161a71f3 9042 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
26ec81e0

9043 The problem was that GLR parsers did not conform to the C standard,
9044 because actions like { $1 = $2 + $3; } expanded to expressions
9045 that invoked YYFILL in separate subexpressions, and YYFILL assigned
9046 to a local variable. The C standard says that expressions
9047 like (var = f ()) + (var = f ()) have undefined behavior.
9048 Another problem was that GCC sometimes issues warnings that
9049 yyfill and its parameters are unused.
9050
9051 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
9052 as possibly unused.
9053 (yyfill): New function.
9054 (YYFILL): Use it.
9055 (yyuserAction): Change type of yynormal to bool, so that it matches
9056 the new yyfill signature. Mark it as possibly unused.
9057
9058
9059 Follow up on a bug I reported in February, where a Bison-generated
9060 parser can loop. Provide a test case and a fix for yacc.c. I
9061 don't have a fix for lalr1.cc or for glr.c, unfortunately.
9062 The original bug report is in:

PE
9064
9065 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
9066 macro's size was becoming unwieldy.
9067 (yyerrlab): Do not discard an empty lookahead symbol, as this
9068 might destroy garbage.
9069 (yyerrorlab): New label, with the old contents of YYERROR,
9070 plus the following change: pop the stack of rhs corresponding
9071 to the production that invoked YYERROR. That is how Yacc
9072 behaves, and POSIX requires this behavior.
9073 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
9074 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
9075 Define 'alarm' to do nothing if unistd.h is not available.
9076 Add a new rule "exp: '-' error;" to test the above change to
9077 data/yacc.c. Use 'alarm' to abort any test taking longer than
9078 10 seconds, as it's probably looping.
9079 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
9080 Also, the new yacc.c generates two fewer diagnostics for an
9081 existing test.

9085 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
9086 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.

9088 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM

9708 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
9709 we don't need to worry about yyerrlab1 being reported as an
9710 "unused label" by non-GCC C compilers. The downside is that if
9711 locations are used then a couple of statements are duplicated each
9712 time YYERROR is invoked, but the upside is that the warnings
9713 should vanish.
9714 (yyerrlab1): Move code to YERROR.

9728 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
9729 when the stacks contain one element, as the loop would otherwise
9730 free the last state, and then use the top state (the one we just
9731 popped). This means that the initial elements will not be freed
9732 explicitly, as is the case in yacc.c; it is not a problem, as
9733 these elements have fake values.

9844 * src/conflicts.c (conflict_report):
9845 Renamed from conflict_report_yacc, removing the old
9846 'conflict_report'. Translate the entire conflict report at once,
9847 so that we don't assume that "," has the same interpretation in
9848 all languages.
9849 (conflicts_output): Use Yacc-style conflict report for each state,
9850 instead of our more-complicated style.
9851 (conflicts_print): Use Yacc-style conflict report, except print
9852 the input file name when not emulating Yacc.
9853 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
9854 Conflicted Reduction, %expect not enough, %expect too much,

9870 * data/yacc.c (yyparse): New local var yylerrsp, to record the
9871 top of the location stack's error locations.
9872 (yyerrlab): Set it. When discarding a token, push its location
9873 onto yylerrsp so that we don't lose track of the error's end.
9874 (yyerrlab1): Now is only the target of YYERROR, so that we can
9875 properly record the location of the action that failed. For GCC
9876 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
9877 GCC warning about yyerrlab1 being unused if YYERROR is unused.
9878 (yyerrlab2): New label, which yyerrlab now falls through to.
9879 Compute the error's location by applying YYLLOC_DEFAULT to
9880 the locations of all the symbols that went into the error.
9881 * doc/bison.texinfo (Location Default Action): Mention that
9882 YYLLOC_DEFAULT is also invoked for syntax errors.
9883 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9884 Error locations include the locations of all the tokens that were
9885 discarded, not just the last token.

9942 If the user does not define YYSTYPE as a macro, Bison now declares it
9943 using typedef instead of defining it as a macro. POSIX requires this.
9944 For consistency, YYLTYPE is also declared instead of defined.
9945
9946 %union directives can now have a tag before the `{', e.g., the
9947 directive `%union foo {...}' now generates the C code
9948 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
9949 The default union tag is `YYSTYPE', for compatibility with Solaris 9
9950 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
9951 instead of `yyltype'.
9952
9953 `yystype' and `yyltype' are now obsolescent macros instead of being
9954 typedefs or tags; they are no longer documented and will be
9955 withdrawn in a future release.

9961 (YYLTYPE): Renamed from yyltype.
9962 (yyltype, yystype): New (and obsolescent) macros,
9963 for backward compatibility.
9964 * data/yacc.c: Likewise.
9965

9967 does not specify a union tag. This is for compatibility with
9968 Solaris 9 yacc.

9987 has (or usually has) an immediately-following braced code.

10014 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
10015 lookahead symbol, and which sets yychar in parser actions) and it

10019 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
10020 as the caller now does that.

10022 (YYEMPTY): Parenthesize right hand side, since others use it.
10023 (yyparse): Don't assume that our generated code is the only code
10024 that sets yychar.

10058
10059 Remove unportable casts and storage allocation tricks.
10060 While we're at it, remove almost all casts, since they
10061 usually aren't needed and are a sign of trouble.
10062
10063 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
10064
10065 * src/derives.c (derives_compute): Do not subtract NTOKENS from
10066 the pointer DSET returned by malloc; this isn't portable.
10067 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
10068 Similarly for DERIVES.
10069 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
10070 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
10071 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
10072
10073 * src/derives.c (derives_compute): Do not bother invoking
10074 int_of_rule_number, since rule numbers are integers.
10075
10076 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
10077 rather than XMALLOC (char, N).
10078
10079 * src/files.c (filename_split): Rewrite to avoid cast.
10080
10081 * src/gram.h (symbol_number_as_item_number,
10082 item_number_as_symbol_number, rule_number_as_item_number,
10083 item_number_as_rule_number):
10084 Now inline functions rather than macros, to avoid casts.
10085 * src/state.h (state_number_as_int): Likewise.
10086 * src/tables.c (state_number_to_vector_number,
10087 symbol_number_to_vector_number): Likewise.
10088
10089 * src/gram.h (int_of_rule_number): Remove; no longer used.
10090
10091 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
10092 since the resulting storage is always stored into.
10093
10094 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
10095 where it's needed.
10096
10097 * src/muscle_tab.c (muscle_m4_output):
10098 Now inline. Return bool, not int.
10099 * src/state.c (state_compare): Likewise.
10100 * src/symtab.c (symbol_check_defined,
10101 symbol_check_alias_consistency, symbol_pack, symbol_translation,
10102 hash_compare_symbol, hash_symbol):
10103 Likewise.
10104 * src/uniqstr.c (uniqstr_print): Likewise.
10105 * src/muscle_tab.c (muscle_m4_output_processor):
10106 New function, to avoid casts.
10107 * src/state.c (state_comparator, stage_hasher): Likewise.
10108 * src/symtab.c (symbol_check_defined_processor,
10109 symbol_check_alias_consistency_processor, symbol_pack_processor,
10110 symbol_translation_processor, hash_symbol_comparator,
10111 hash_symbol_hasher): Likewise.
10112 * src/uniqstr.c (uniqstr_print_processor): Likewise.
10113 * src/muscle_tab.c (muscles_m4_output):
10114 Use new functions instead of casting old functions unportably.
10115 * src/state.c (state_hash_new): Likewise.
10116 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
10117 symbols_token_translations_init):
10118 Likewise.
10119 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
10120
10121 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
10122 var instead of casting to long, to avoid casts.
10123 (prepare_states): Use MALLOC rather than alloca, so that we don't
10124 have to worry about alloca.
10125 * src/state.c (state_hash_lookup): Likewise.
10126
10127 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
10128 local var instead of casting to unsigned char, to avoid casts.
10129
10130 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
10131 STATE_ALLOC): Remove.
10132 (transitions_new, errs_new, reductions_new, state_new): Use malloc
10133 rather than calloc, and use offsetof to avoid allocating slightly
10134 too much storage.
10135 (state_new): Initialize all members.
10136
10137 * src/state.c (state_hash): Use unsigned accumulator, not signed.
10138
10139 * src/symtab.c (symbol_free): Remove; unused.
10140 (symbol_get): Remove cast in lhs of assignment.
10141 (symbols_do): Now static. Accept generic arguments, not
10142 hashing-related ones.
10143
10144 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
10145 (symbol_processor): Remove.
10146 (symbols_do): Remove decl; now static.
10147

10150 (<inttypes.>, <stdint.h>): Include if available.
10151 (uintptr_t): New type, if system lacks it.
10152 (CALLOC, MALLOC, REALLOC): New macros.
10153 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
10154 new macros.
10155
10156 * src/tables.c (table_size): Now int, to pacify GCC.
10157 (table_grow, table_ninf_remap): Use signed table size.
10158 (save_row): Don't bother initializing locals when not needed.
10159 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
10160 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
10161
10162 * src/vcg.h: Correct misspellings.
10163
10164 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
10165
10166
10167 * src/getargs.c (getargs): Don't assume EOF == -1.

10171 Change identifier spellings to avoid collisions with names
10172 that are reserved by POSIX.
10173
10174 Don't use names ending in _t, since POSIX reserves them.
10175 For consistency, remove _e and _s endings -- they're weren't
10176 needed to remove ambiguity. All uses changed.
10177 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
10178 turn was just renamed from struniq_t.
10179 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
10180 which in turn was just renamed from struniq_processor_t.

10388 processing of Yacc white space and equivalents here.
10389 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
10390 instead of returning ID immediately, since we need to search for
10391 a subsequent colon.
10392 (<INITIAL>"'", "\""): Save token_start.
10393 (<INITIAL>"%{", "{", "%%"): Save code_start.

10775 to avoid shadowing warnings by GCC.
10776
10777 * data/glr.c (inline): Remove #define. It's the user's
10778 responsibility to #define it away, just like 'const'.
464c6927 10779 This fixes one of the bugs reported by Nelson H. F. Beebe in

10789 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
10790 * src/scan-gram.l: Revamp regular expressions so that " and '
10791 do not confuse xgettext.
10792
10793 * src/struniq.h (struniq_new): Do not declare the return type

10948 Use new @ escapes consistently. Represent brackets with @{ and @}
10949 rather than @<:@ and @:>@, since this works a bit better with dumb
10950 editors like vi. Represent @ with @@, since @ is now consistently
10951 an escape. Use @oline@ and @ofile@ rather than __oline__ and
10952 __ofile__, to avoid unexpected expansions. Similarly, use @output
10953 rather than #output.
10954
10955 * data/c.m4 (b4_copyright): Omit file name from comment, since
10956 the file name could contain "*/".
10957 (b4_synclines_flag): Don't quote the 2nd argument; it should already
10958 be quoted. All uses changed.

10972 mishandled funny characters in file names, and anyway it isn't
10973 needed any more.
10974 * data/yacc.c: Likewise.
10975 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.

10986 (prepare_symbols): Quote tokens for M4.
10987 (prepare): Don't insert output_infix, output_prefix,
10988 output_parser_name, output_header_name; this is now down by scan-skel.
10989 Insert skeleton as a C string.

10995 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
10996 escapes other than \\ and \'; this simplifies the code.

10998 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
10999 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
11000 Use new escapes @{ and @} for [ and ].
11001
11002 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
11003 them with auto vars.
11004 Switch to new escape scheme, where @ is the escape character uniformly.
11005 Abort if a stray escape character is found. Avoid unbounded input
11006 buffer when parsing non-escaped text.
11007

11018 (yygetLRActions, yyrecoverParseError): Use them.
11019
11020 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
11021 counted in the token inserted at end of file. Now takes
11022 location_t *, not location_t, so that the location can be
11023 adjusted. All uses changed.
11024

11029 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
11030 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
11031 abort ();'. This reduces the runtime of the "Many lookaheads"

11292 indicates one.
11293 * src/output.c (output_skeleton): Use xfclose rather than fclose

11360 The last OS that we could find where this wouldn't work is
11361 SunOS 3.5, and that's too old to worry about now.
11362
11363 * data/glr.c (struct yyltype): Define members even when not

11737 Let nondeterministic skeletons be usable with deterministic
11738 tables.
11739
11740 With the patch, GAWK compiled by GCC without -O2 passes its test
11741 suite using a GLR parser driven by LALR tables. It fails with -O2
11742 because `struct stat' gives two different answers on my machine:
11743 88 (definition of an auto var) and later 96 (memset on this var).
11744 Hence the stack is badly corrumpted. The headers inclusion is to
11745 blame: if I move the awk.h inclusion before GLR's system header
11746 inclusion, the two struct stat have the same size.

11856
11857 Portability fixes for bitsets; this also avoids several GCC
11858 warnings.
11859
11860 * lib/abitset.c: Include <stddef.h>, for offsetof.
11861 * lib/lbitset.c: Likewise.
11862
11863 * lib/abitset.c (abitset_bytes): Return a size that is aligned
11864 properly for vectors of objects. Do not assume that adding a
11865 header size to a multiple of a word size yields a value that is
11866 properly aligned for the whole union.
11867 * lib/bitsetv.c (bitsetv_alloc): Likewise.
11868
11869 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
11870 unique names for structures.
11871 * lib/ebitset.c (ebitset_bytes): Likewise.
11872 * lib/lbitset.c (lbitset_bytes): Likewise.
11873
11874 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
11875 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
11876 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
11877 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
11878 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
11879 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
11880 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
11881 to improve the type-checking that GCC can do.
11882 * lib/bitset.c (bitset_op4_cmp): Likewise.
11883 * lib/bitset_stats.c (bitset_stats_count,
11884 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
11885 bitset_stats_copy, bitset_stats_disjoint_p,
11886 bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
11887 bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
11888 bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
11889 bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
11890 bitset_stats_and_or_cmp, bitset_stats_andn_or,
11891 bitset_stats_andn_or_cmp, bitset_stats_or_and,
11892 bitset_stats_or_and_cmp): Likewise.
11893 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
11894 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
11895 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
11896 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
11897
11898 * lib/abitset.h: Include bitset.h, not bbitset.h.
11899 * lib/ebitset.h: Likewise.
11900 * lib/lbitset.h: Likewise.
11901
11902 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
11903 All instances of parameters of type enum bitset_opts are now of
11904 type enum_bitset_opts, to conform to the C Standard, and similarly
11905 for enum_bitset_type.
11906 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
11907 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
11908
11909 Do not use "struct bitset_struct" to mean different things in
11910 different modules. Not only is this confusing, it violates
11911 the C Standard, which requires that structure types in different
11912 modules must be compatible if one is to be passed to the other.
11913 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
11914 All instances of "struct bitset_struct *" replaced with "bitset".
11915 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
11916 (union bitset_union, struct abitset_struct, struct ebitset_struct,
11917 struct lbitset_struct, struct bitset_stats_struct): New types.
11918 All uses of struct bitset_struct changed to union bitset_union,
11919 etc.
ba0fe3c7 11920 * lib/abitset.c (struct abitset_struct, abitset,
f28a0f2d
PE
11921 struct bitset_struct): Remove.
11922 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
11923 struct bitset_struct): Remove.
11924 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
11925 bitset_struct): Remove.
11926 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
11927 Likewise.
11928
11929 Do not call a function of type T using a call that assumes the
11930 function is of a different type U. Standard C requires that a
11931 function must be called with a type that is compatible with its
11932 definition.
11933 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
11934 New decls.
11935 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
11936 New functions.
11937 * lib/ebitset.c (PFV): Remove.
11938 * lib/lbitset.c (PFV): Likewise.
11939 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
11940 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
11941 decls.
11942 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
11943 (ebitset_vtable): Use them.
11944 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
11945 lbitset_xor): New functions.
11946 (lbitset_vtable): Use them.
11947
11948 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
11949 Declare.
11950
11951 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
11952 GCC warning.
11953 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
11954 Use offsetof, for simplicity.

11957
11958 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
11959 the same width as int. This reapplies a hunk of the 2002-08-12 patch
161a71f3 11960 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,

11967 Version 1.50.
11968
11969 * configure.ac (AC_INIT), NEWS: Increment version number.
11970
11971 * doc/bison.texinfo: Minor spelling, grammar, and white space
11972 fixes.
11973 (Symbols): Mention that any negative value returned from yylex
11974 signifies end-of-input. Warn about negative chars. Mention
11975 the portable Standard C character set.
11976
11977 The GNU coding standard says CFLAGS and YFLAGS are reserved
11978 for the installer to set.
11979 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
11980 * src/Makefile.am (AM_CFLAGS): Likewise.
11981 (AM_YFLAGS): Renamed from YFLAGS.
11982
11983 Fix some MAX and MIN problems.
11984 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
11985 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
11986 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
11987 * src/reader.c (reader): Use it.
11988
11989 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
11990 POSIX 1003.1-2001 has removed fgrep.
11991
119922002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
11993
11994 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
11995 interpreted as signed.
11996 * lib/ebitset.c (ebitset_list): Fix bug.

12003 abitset_size, abitset_list, abitset_list_reverse, abitset_list):
12004 Use bitset_bindex, not int or unsigned int or size_t, to count bits.

15520 these states are automatically computed from the initial state.
15521 (generate_states): Adjust.
15522 * src/print.c: When reporting a rule number to the user, substract
15523 1, so that the axiom rule is rule 0, and the first user rule is 1.
15524 * src/reduce.c: Likewise.
15525 * src/print_graph.c (print_core): For the time being, just as for
15526 the report, depend upon --trace-flags to dump the full set of

15528 * src/reader.c (readgram): Once the grammar read, insert the rule
15529 0: `$axiom: START-SYMBOL $'.
15530 * tests/set.at: Adjust: rule 0 is now displayed, and since the
15531 number of the states has changed (the final state is no longer
15532 necessarily the last), catch up.

15556 (parse_token_decl): If the token being defined has value `0', it
15557 is the eoftoken.
15558 (packsymbols): No longer hack `tags' to insert `$' by hand.
15559 Be sure to preserve the value of the eoftoken.
15560 (reader): Make sure eoftoken is defined.
15561 Initialize nsyms to 0: now eoftoken is created just like the others.
15562 * src/print.c (print_grammar): Don't special case the eof token.
15563 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
15564 lie anyway, albeit pleasant.
15565 * tests/calc.at: Exercise error messages with eoftoken.
15566 Change the grammar so that empty input is invalid.

16407 Because useless nonterminals are now kept alive (instead of being

16573 Do not limit the number of items in the stack to a value that fits
16574 in 'int', as this is an arbitrary limit on hosts with 64-bit
16575 size_t and 32-bit int.

18803 The location tracking mechanism is precious for parse error
18804 messages. Nevertheless, it is enabled only when `@n' is used in

18839 Test also `--verbose', `--defines' and `--name-prefix'. Testing
18840 the latter demonstrates a flaw in the handling of non debugging
18841 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
18842 was used in order to simplify:
18843
18844 #if YYDEBUG

18853 if (yydebug)
18854 {
18855 ...

18913 Bison used an implementation of `xmalloc' based on `calloc', and
18914 at various places it does depend upon the initialization to 0. I
18915 have not tried to isolate the pertinent places, and all the former
18916 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
18917 someone should address this issue.

19325 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
19326 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

19328 defined only if `YYDEBUG != 0'.

20005 declaration to allow a multi-character symbol as an alias.
20006 (parse_thong_decl): New function.

20017 Revised and use multiple warnxxx functions to avoid using VARARGS1.
20018 (read_declarations): Improve the error message for
20019 an invalid character. Do not abort.

20047 (lex): Use literalchar.
20048 (lex): Implemented "..." tokens.
20049 (literalchar, lex, parse_percent_token): Made tokenbuffer
20050 always contain the token. This includes growing the token
20051 buffer while reading an integer.
20052 (parse_percent_token): Replaced if-else statement with percent_table.
20053 (parse_percent_token): Added % declarations as another
20054 way to specify the flags -n, -l, and -r. Also added hooks for
20055 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
20056 major changes to files.c.
20057 (lex) Retain in the incoming stream a character following
20058 an incorrect '/'.
20059 (skip_white_space, lex): Revised most error messages
20060 and changed fatal to warn to avoid aborting.
