7 Fix minor problems encountered by a fresh bootstrap.
8 * data/glr.c, data/yacc.c: Do not use apostrophes in '#' comments,
9 as they confuse xgettext, which tries to parse them as C character
10 constants in a preprocessor directive.
11 * data/yacc.c (yy_lac): Don't use printf %d format on *yyesp, as
12 that expression might not promote to int on some platforms.
13 * src/parse-gram.c, src/parse-gram.h: Regenerate.

17 Improve error messages for `$' or `@' followed by `.' or `-'.
18 Previously, for this special case of an invalid reference, the
19 usual "symbol not found in production:" was printed. However,
20 because the symbol name was parsed as the empty string, that
21 message was followed immediately by a newline instead of a symbol
22 name. In reality, this is a syntax error, so the reference is
23 invalid regardless of the symbols actually appearing in the
24 production. Discussed at
25 <http://lists.gnu.org/archive/html/bison-patches/2011-01/msg00012.html>.
26 * src/scan-code.l (parse_ref): Report the above case as a syntax
27 error. Other than that, continue to handle this case like any
28 other invalid reference that Bison manages to parse because
29 "possibly meant" messages can still be helpful to the user.
30 * tests/named-refs.at ($ or @ followed by . or -): New test group.

115 parse.lac.es-capacity-initial. Accept parse.lac.memory-trace
116 with values of "failures" (default) or "full".
117 (b4_declare_parser_state_variables): Add yyesa, yyes, and
118 yyes_capacity variables.
119 (YYSTACK_USE_ALLOCA): Ignore it if LAC requested.
120 (YYSTACK_ALLOC, YYSTACK_FREE, YYSTACK_ALLOC_MAXIMUM): Define if
121 LAC requested.
122 (YYCOPY_NEEDED): New cpp macro.
123 (YYCOPY): Define if LAC requested.
124 (yy_lac_stack_realloc): New function implementing stack
125 reallocations. Use YYMAXDEPTH for maximum stack size given that
126 the stack should never need to grow larger than the main state
127 stack needs to grow without LAC.
128 (YY_LAC_ESTABLISH): Update yy_lac invocation.
129 (yy_lac): Add arguments for exploratory stack memory data
130 recorded in the main parser. Invoke yy_lac_stack_realloc when
131 reallocation is necessary.
132 (yysyntax_error): Add the same new arguments and pass them to
133 yy_lac.
134 (yypstate_delete): Free yyes if necessary.
135 (yyesa, yyes, yyes_capacity): #define these to yypstate members
136 in the case of push parsing.
137 (yyparse, yypush_parse): Initialize yyes and yyes_capacity.

150 parse.lac: implement as %define variable.
151 LAC = lookahead correction. See discussion at
152 <http://lists.gnu.org/archive/html/bison-patches/2009-09/msg00034.html>.
153 However, one point there must be corrected: because of %nonassoc,
154 LAC is *not* always redundant for lr.type=canonical-lr.
155 * data/yacc.c: Accept values of "none" (default) or "full" for
156 parse.lac. Accept %define parse.lac.es-capacity to specify
157 capacity of LAC's temporary exploratory stack. It defaults to 20
158 and, for now, will not grow dynamically.
159 (b4_lac_flag, b4_lac_if): New m4 macros. Evaluate as true for
160 parse.lac!=none.
161 (YYBACKUP): Invoke YY_LAC_DISCARD.
162 (YY_LAC_ESTABLISH, YY_LAC_DISCARD): New cpp macros that invoke
163 yy_lac and track when it needs to be invoked
164 (yy_lac): New function that, given the current stack, determines
165 whether a token can eventually be shifted. Return status mimics
166 yyparse return status.
167 (yysyntax_error): Change yystate argument to yyssp so stack top
168 can be passed to yy_lac. If LAC is requested, build expected
169 token list by invoking yy_lac for every token instead of just
170 checking the current state for lookaheads. Return 2 if yy_lac
171 exhausts memory.
172 (yyparse, yypush_parse): Use local variable yy_lac_established and
173 cpp macros YY_LAC_ESTABLISH and YY_LAC_DISCARD to implement LAC.
174 Update yysyntax_error invocation. Add yyexhaustedlab code if LAC
175 is requested.
176 * tests/conflicts.at (%nonassoc and eof): Extend to check the
177 effect of each of -Dlr.type=canonical-lr and -Dparse.lac=full.
178 (%error-verbose and consistent errors): Likewise.
179 (LAC: %nonassoc requires splitting canonical LR states): New test
180 group demonstrating how LAC can fix canonical LR.
181 * tests/input.at (LAC: Errors for %define): New test group.
182 * tests/regression.at (LAC: Exploratory stack): New test group.
183 (LAC: Memory exhaustion): New test group.

196 yysyntax_error: adjust prior fixes for branch-2.5's lalr1.cc.
197 On master, there is no yychar in lalr1.cc, but there is on
198 branch-2.5, and the prior cherry-pick of "Fix handling of yychar
199 manipulation in user semantic actions" wasn't adjusted for that
200 difference.
201 * data/lalr1.cc (yy::parser::parse): Translate yychar before
202 every use of yytoken, and add comments explaining this approach.

208 yysyntax_error: fix for consistent error with lookahead.
209 * NEWS (2.5): Document.
210 * data/yacc.c (yysyntax_error): In a verbose syntax error
211 message while in a consistent state with a default action (which
212 must be an error action given that yysyntax_error is being
213 invoked), continue to drop the expected token list, but don't
214 drop the unexpected token unless there actually is no lookahead.
215 Moreover, handle that internally instead of returning 1 to tell
216 the caller to do it. With that meaning of 1 gone, renumber
217 return codes more usefully.
218 (yyparse, yypush_parse): Update yysyntax_error usage. Most
219 importantly, set yytoken to YYEMPTY when there's no lookahead.
220 * data/glr.c (yyreportSyntaxError): As in yacc.c, don't drop the
221 unexpected token unless there actually is no lookahead.
222 * data/lalr1.cc (yy::parser::parse): If there's no lookahead,
223 set yytoken to yyempty_ before invoking yysyntax_error_.
224 (yy::parser::yysyntax_error_): Again, don't drop the unexpected
225 token unless there actually is no lookahead.
226 * data/lalr1.java (YYParser::parse): If there's no lookahead,
227 set yytoken to yyempty_ before invoking yysyntax_error.
228 (YYParser::yysyntax_error): Again, don't drop the unexpected
229 token unless there actually is no lookahead.
230 * tests/conflicts.at (%error-verbose and consistent
231 errors): Extend test group to further reveal how the previous
232 use of the simple "syntax error" message was too general. Test
233 yacc.c, glr.c, lalr1.cc, and lalr1.java. No longer an expected
234 failure.
235 * tests/java.at (AT_JAVA_COMPILE, AT_JAVA_PARSER_CHECK): Move
236 to...
237 * tests/local.at: ... here.
238 (_AT_BISON_OPTION_PUSHDEFS): Push AT_SKEL_JAVA_IF definition.
239 (AT_BISON_OPTION_POPDEFS): Pop it.
240 (AT_FULL_COMPILE): Extend to handle Java.

718 portability: fix several issues with M4 subprocess.
719
720 M4's output pipe was not being drained upon fatal errors during
721 scan_skel. As a result, broken-pipe messages from M4 were seen
722 on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
723 failure in the test suite. The problem was that, on platforms
724 where the default disposition for SIGPIPE is ignore instead of
725 terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
726 then reported it. However, there's some sort of race condition,
727 because the new test group occasionally succeeded.
728 Reported by Albert Chin at

734 Switching to create_pipe_bidi suggested by Akim Demaille.

736 To attempt to solve both of these problems, switch to gnulib's

738 way, clean up file name conflict handling, which was affected by
739 the broken-pipe problem before the switch.

822 Fix some comments concerning LR(0) versus LALR(1).
823
824 Stop equating LR(0) with nondeterminism and LALR(1) with
825 determinism. That is, if all states are consistent, then LR(0)
826 tables are deterministic. On the other hand, LALR(1) tables
827 might be nondeterministic before conflict resolution, and GLR
828 permits LALR(1) tables to remain nondeterministic.

907 portability: `<' and `>' are not always defined on addresses.

932 Fix handling of yychar manipulation in user semantic actions.
933 The problem was that yacc.c didn't always update the yychar
934 translation afterwards. However, other skeletons appear to be
935 fine. glr.c appears to already translate yychar before every
936 use. lalr1.cc does not define yychar and does not document its
937 replacement, yyla, for users. It does provide yyclearin, but
938 that does not manipulate yyla and thus requires no translation
939 update. In lalr1.java, yychar is out of scope during semantic
940 actions.
941 * NEWS (2.5): Document.
942 * data/yacc.c (YYBACKUP): Don't bother translating yychar into
943 yytoken here.
944 (yyparse, yypush_parse): Instead, translate before every use of
945 yytoken, and add comments explaining this approach.
946 * tests/actions.at (Destroying lookahead assigned by semantic
947 action): New test group checking that translation happens before
948 lookahead destructor calls at parser return. Previously,
949 incorrect destructors were called.
950 * tests/conflicts.at (%error-verbose and consistent
951 errors): New test group checking that translation happens at
952 syntax error detection before the associated verbose error
953 message and the associated lookahead destructor calls. While
954 the destructor call is fixed by this patch, the verbose error
955 message is currently incorrect due to another bug (see
956 comments in test group), so this is an expected failure for now.

1135 yysyntax_error: avoid duplicate lookahead collection.
1136 Except when memory reallocation is required, this change
1137 eliminates the need to invoke yysyntax_error twice and thus to
1138 repeat the collection of lookaheads. It also prepares for
1139 future extensions that will make those repetitions more

1396 (yygetLRActions): Check for default value from yypact. It

1399 However, the code may evolve after this subtlety is forgotten.
1400 Also, update for rename to yytable_value_is_error. Because that

1486 In all escape sequence complaints, don't escape the initial
1487 backslash, and don't quote when the sequence appears at the end
1488 of the complaint line unless there's whitespace that quotearg
1489 won't escape.
1490 Consistently say "invalid" not "unrecognized".

1492 characters in character literal" warning for invalid escape
1493 sequences; that is, consistently discard those sequences.

1674 Pacify "gcc -Wunused" for the input function from Flex.
1675 Reported by Alex Rozenman. This warning shows up with gcc-4.3.0
1676 and later.
1677 * src/scan-code.l: Add "%option noinput", which I cannot find in
1678 the Flex manual, but which Flex has supported since at least as
1679 far back as 2.5.4. However, if any of our developers still use
1680 Flex 2.5.4, they'll need to stop configuring with
1681 --enable-gcc-warnings because "%option noinput" didn't work

4329 * src/lalr.c (state_lookahead_tokens_count): For code readability,
4330 move the check for disabled transitions to an aver since conflict
4331 resolution hasn't happened yet.
4332
4333 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
4334 labels a state as inconsistent just because it has error transitions.
4335 The original form of this check appeared in revision 1.1 of lalr.c,
4336 which was committed on 1991-12-21. Now (at least), changing the
4337 consistency label on such a state appears to have no useful effect in
4338 any of the places it is examined, which I enumerate below. The key
4339 point to understanding each item in this enumeration is that a state
4340 with an error transition is labelled consistent in the first place only
4341 if it has no rules, so the check cannot matter for states that have
4342 rules. (1) Labelling a state as inconsistent will cause set_conflicts
4343 to try to identify its conflicts, and a state must have *rules* to have
4344 conflicts. (2) Labelling a state as inconsistent will affect how
4345 action_row sets the default *rule* for the state. (3) Labelling a
4346 state as inconsistent will cause build_relations to add lookback edges
4347 to *rules* in that state.

4848 Clean up %define and %code implementation in M4 some. Most
4849 importantly, rename all related macros to be in the b4_percent_define
4850 and b4_percent_code namespaces. Also, complete support for `.' in
4851 %define variable names and %code qualifiers.
4852 * data/bison.m4 (b4_check_user_names): Check for special
4853 "SKELETON-NAMESPACE(name)" macros instead of using two nested
4854 m4_foreach loops.
4855 (b4_get_percent_define, b4_get_percent_code): Rename to...
4856 (b4_percent_define_get, b4_percent_code_get): ... these.
4857 Extend documentation with examples.
4858 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
4859 b4_percent_define_skeleton_variables and
4860 b4_percent_code_skeleton_qualifiers.
4861 Expect any value for the %define variable `foo' to be stored in the
4862 macro named `b4_percent_define(foo)'; expect any %code blocks for the
4863 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
4864 expect any unqualified %code blocks to be stored in a macro named
4865 `b4_percent_code_unqualified'.
4866 Use m4_indir so that %define variable names and %code qualifiers can
4867 contain `.', which is allowed by the grammar parser.
4868 (b4_percent_define_default): New macro to set a default value for a
4869 %define variable.
4870 (m4_wrap): Update wrapped code, and fix some underquoting.
4871 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
4872 Expect grammar uses of %define variables and %code qualifiers to be
4873 defined in b4_percent_define_user_variables and
4874 b4_percent_code_user_qualifiers.
4875 * data/c++.m4: Use b4_percent_define_default rather than
4876 m4_define_default. Fix some underquoting. Skeleton usage of %define
4877 variable define_location_comparison now implies skeleton usage of
4878 %define variable filename_type.

4987 Instead of having skeletons declare all valid %define variables and

4990 variable or qualifier is not used by the skeleton in the current
4991 invocation regardless of whether it might sometimes be used by that
4992 skeleton in other invocations. Also, move all %define value macros to
4993 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
4994 form, which is replaced by %code.
4995 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...

4999 Warn instead of complaining.
5000 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define

5287 Encapsulate code properties and related functionality for the various
5288 destructors, printers, and actions into a code_props structure and
5289 interface. This patch merely implements code_props in scan-code.h and
5290 scan-code.l. Future patches will rewrite other modules to use it.
5291 Discussed starting at
5292 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
5293 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
5294 consistently initialize const structs that have an empty location
5295 field.
5296 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
5297 to ensure consistency.
5298 * src/scan-code.h (code_props): New structure.
5299 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
5300 function, macro, and const global variable for initializing a
5301 code_props with no code.
5302 (code_props_plain_init, code_props_symbol_action_init,
5303 code_props_rule_action_init, code_props_translate_code): The rest of
5304 the new code_props functional interface. Among other things, the init
5305 functions set the code_props kind field so that
5306 code_props_translate_code will know whether to behave like
5307 translate_symbol_action, translate_rule_action, or translate_code.
5308 These old translate functions must remain until all other modules are
5309 updated to use the new code_props interface.
5310 (code_scanner_last_string_free): New function similar to
5311 gram_scanner_last_string_free.
5312 (code_scanner_free): Add documentation.

5314 (code_lex): Make it static, add a code_props* argument, and remove the
5315 rule argument.
5316 (last_string): New static global similar to the one in scan-gram.l.
5317 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
5318 instead of rule.
5319 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
5320 code_props since Bison may one day use this information for destructors
5321 and printers.
5322 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
5323 (handle_action_dollar): Use symbol_list_n_get and set used flag
5324 directly since symbol_list_n_used_set is removed.
5325 (translate_action): Add a code_props* argument and remove the rule,
5326 action, and location arguments. Pass the code_props* on to code_lex.
5327 (translate_rule_action, translate_symbol_action, translate_code):
5328 Rewrite as wrappers around the new code_props interface.

5723 `bison ', use m4_index instead of m4_substr since chopping up a string
5724 containing M4-special characters causes problems here.
5725
5726 Fix a couple of bugs related to special characters in user-specified
5727 file names, and make it easier for skeletons to compute output file
5728 names with the same file name prefix as Bison-computed output file
5729 names.
5730 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
5731 b4_parser_file_name and b4_spec_defines_file instead of
5732 @output_parser_name@ and @output_header_name@, which are now redundant.
5733 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
5734 b4_parser_file_name, b4_spec_defines_file, and the new
5735 @basename(FILENAME@) instead of @output_parser_name@ and
5736 @output_header_name@, which inappropriately escaped the file names as
5737 C string literals.

5745 characters are escaped properly.
5746 * src/output.c (prepare): Define muscle file_name_all_but_ext as
5747 all_but_ext.
5748 For pkgdatadir muscle, maintain previous functionality by using
5749 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
5750 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
5751 digraphs would never be expanded. Hopefully no one has M4-special
5752 characters in his Bison installation path.
5753 * src/scan-skel.l: Don't parse @output_header_name@ and

6622 Whether the default %destructor/%printer applies to a particular symbol
6623 isn't a question of whether the user *declares* that symbol (in %token,
6624 for example). It's a question of whether the user by any means
6625 *defines* the symbol at all (by simply using a char token, for
6626 example). $end is defined by Bison whereas any other token with token
6627 number 0 is defined by the user. The error token is always defined by
6628 Bison regardless of whether the user declares it with %token, but we
6629 may one day let the user define error as a nonterminal instead.
6630 * NEWS (2.3+): Say "user-defined" instead of "user-declared".

6731 alias, check and set its alias's user token number instead of its own,
6732 which is set to indicate the alias. Previously, every occurrence of
6733 the character token in the grammar overwrote that alias indicator with
6734 the character code.

7143 haven't been translated yet.
7144 Record the midrule's parent rule and its RHS index within the parent
7145 rule.
7146 (grammar_current_rule_action_append): Don't translate the action yet
7147 since not all symbol declarations may have been parsed yet and, thus,
7148 warnings about types for $$, $n, @$, and @n can't be reported yet.
7149 (packgram): Translate the action and invoke grammar_rule_check now that
7150 all symbol declarations have been parsed.
7151 * src/scan-code.l (handle_action_dollar): Now that this is invoked
7152 after parsing the entire grammar file, the symbol list here in the case
7153 of a midrule is actually the midrule's empty RHS, so reference its
7154 parent rule's RHS where necessary.
7155 On the other hand, now that you can already know it's a midrule, you
7156 aren't forced to think $$ has the same type as its parent rule's $$.
7157 (handle_action_at): In the case of a midrule, reference the parent rule
7158 where necessary.

7160 members.
7161 (symbol_list_length): Now that this is invoked after all rules have
7162 been parsed, a NULL symbol (rather than a NULL symbol list node)
7163 terminates a rule. symbol_list_print already does this correctly.
7164 * src/symlist.h (symbol_list.midrule_parent_rule,
7165 symbol_list.midrule_parent_rhs_index): New members so that midrules can
7166 remember their relationships with their parents.
7167 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
7168 fixed by the above patch.
7169 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
7170 implementing...
7171 (Unused values): ... this old test case and...
7172 (Unused values before symbol declarations): ... this new test case.
7173 This one is the same as `Unused values' except that all symbol

7690 Also, the embedded comments in this test case claim it checks the case
7691 of an empty RHS that has inherited the initial location. However, the
7692 corresponding LHS was already resolved, so yyresolveLocations didn't
7693 actually have reason to modify it. Fix this by forcing
7694 nondeterministic operation at the beginning of the parse.

9167 Use unlocked I/O for a minor performance improvement on hosts like

9452 (yyreport_syntax_error_): Remove, replaced by...
9453 (yysyntax_error_): this which returns a string and leaves to the
9454 caller the call to the users' error function.
9455 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
9456 Move from members of the parser object...

9618 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
9619 that the byte '\0xff' is not printable in the C locale; it is,
9620 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
9621 not printable, so use '\0x81' to test.

9678 it's error-prone and "make maintainer-distcheck" rejects it.

9790 and isn't needed since ./types shouldn't be emitting trailing
9791 spaces.

9861 Add i18n support to the GLR skeleton. Partially fix the C++
9862 skeleton; a C++ expert needs to finish this. Remove debugging
9863 msgids; there's little point to having them translated, since they
9864 can be understood only by someone who can read the
9865 (English-language) source code.
9866
9867 Generate runtime-po/bison-runtime.pot automatically, so that we
9868 don't have to worry about garbage getting in that file. We'll
9869 make sure after the next official release that old msgids don't
9870 get lost. See

9876 Fix typos in explanations of the runtime file.

9878 Use standard Makefile.in.in in runtime-po, since we'll arrange
9879 for backward-compatible bison-runtime.po files in a different way.

9881 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
9882 Translate messages intended for users.
9883 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
9884 the wording in the other skeletons. We don't know that the memory
9885 is virtual.

9887 Use same method that yacc.c uses.
9888 Don't translate debugging messages.
9889 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
9890 it doesn't work (yet), and requires C++ expertise to fix.

9892 Move defn to a more logical place, to be consistent with other
9893 skeletons.
9894 Don't translate debugging messages.
9895 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
9896 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
9897 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.

10208 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
10209 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
10210 the user's name space.
10211 (alloca): Include <stdlib.h> to get it, if it's not built in.
10212 (YYMALLOC, YYFREE): Define only if needed.
10213 (malloc, free): Declare, but only if needed, as this infringes on
10214 the user name space.

10246 Various maintainer cleanups.

10248 conftest*, for benefit of CVS commands run at the same time as
10249 "configure". Add build-aux, since "bootstrap" now creates it and
10250 its subfiles.
10251 * Makefile.cfg (move_if_change): Remove.
10252 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
10253 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

10272 fopen-safer.c, stdio-safer.h, unistd-safer.h.
10273 * lib/subpipe.c: Include "unistd-safer.h".
10274 (create_subpipe): Make sure all the newly-created
10275 file descriptors are > 2, so that diagnostics don't
10276 get sent down them (which might cause Bison to hang, in theory).
10277 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.

11102 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
11103 whether the reducion was empty or not. This leaves room to
11104 improve the use of YYLLOC_DEFAULT in such a case.
11105 lalr1.cc is still experimental, so changing this is acceptable.
11106 And finally, there are probably not many users who changed the
11107 handling of locations in GLR, so changing is admissible too.

11257 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
11258 the extra Bison directives instead of the whole series.
11259 Change the grammar so that there are recoverable errors, and
11260 unrecoverable errors. Now we can have the parser give up before
11261 consuming the whole input. As a result we now can observe that
11262 the lookahead is freed when needed.
11263 Change the parser source to parse argv[1] instead of a hard coded
11264 string.
11265 Simplify yylex, and give a value and location to EOF.
11266 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
11267 passed directives already coded in the file.
11268 Add some tests to check the location of "error".
11269 For some tests, the C++ parser is correct, and not yacc.c.
11270 For other tests, they provide different, but unsatisfying, values,
11271 so keep the C++ value so that at least one parser is "correct"
11272 according to the test suite.

11452 Spent a few hours checking out which prerequisite versions the
11453 current sources actually require. I went all the way back to
11454 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
11455 a seemingly endless set of combinations of versions more recent
11456 than that. The bottom line is that the current sources require
11457 fairly recent versions of the build tools, and it'll be some work
11458 to change this.

11974 When reducing initial empty rules, Bison parser read an initial
11975 location that is not defined. This results in garbage, and that
11976 affects Bison's own parser. Therefore we need (i) to extend Bison

12271 Fix a GLR parser bug I reported in February; see
161a71f3 12272 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
26ec81e0

12273 The problem was that GLR parsers did not conform to the C standard,
12274 because actions like { $1 = $2 + $3; } expanded to expressions
12275 that invoked YYFILL in separate subexpressions, and YYFILL assigned
12276 to a local variable. The C standard says that expressions
12277 like (var = f ()) + (var = f ()) have undefined behavior.
12278 Another problem was that GCC sometimes issues warnings that
12279 yyfill and its parameters are unused.
12280
12281 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
12282 as possibly unused.
12283 (yyfill): New function.
12284 (YYFILL): Use it.
12285 (yyuserAction): Change type of yynormal to bool, so that it matches
12286 the new yyfill signature. Mark it as possibly unused.
12287
12288
12289 Follow up on a bug I reported in February, where a Bison-generated
12290 parser can loop. Provide a test case and a fix for yacc.c. I
12291 don't have a fix for lalr1.cc or for glr.c, unfortunately.
12292 The original bug report is in:

12294
12295 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
12296 macro's size was becoming unwieldy.
12297 (yyerrlab): Do not discard an empty lookahead symbol, as this
12298 might destroy garbage.
12299 (yyerrorlab): New label, with the old contents of YYERROR,
12300 plus the following change: pop the stack of rhs corresponding
12301 to the production that invoked YYERROR. That is how Yacc
12302 behaves, and POSIX requires this behavior.
12303 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
12304 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
12305 Define 'alarm' to do nothing if unistd.h is not available.
12306 Add a new rule "exp: '-' error;" to test the above change to
12307 data/yacc.c. Use 'alarm' to abort any test taking longer than
12308 10 seconds, as it's probably looping.
12309 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
12310 Also, the new yacc.c generates two fewer diagnostics for an
12311 existing test.

12939 we don't need to worry about yyerrlab1 being reported as an

12959 when the stacks contain one element, as the loop would otherwise
12960 free the last state, and then use the top state (the one we just
12961 popped). This means that the initial elements will not be freed
12962 explicitly, as is the case in yacc.c; it is not a problem, as
12963 these elements have fake values.

13100 * data/yacc.c (yyparse): New local var yylerrsp, to record the
13101 top of the location stack's error locations.
13102 (yyerrlab): Set it. When discarding a token, push its location
13103 onto yylerrsp so that we don't lose track of the error's end.
13104 (yyerrlab1): Now is only the target of YYERROR, so that we can
13105 properly record the location of the action that failed. For GCC
13106 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
13107 GCC warning about yyerrlab1 being unused if YYERROR is unused.
13108 (yyerrlab2): New label, which yyerrlab now falls through to.
13109 Compute the error's location by applying YYLLOC_DEFAULT to
13110 the locations of all the symbols that went into the error.
13111 * doc/bison.texinfo (Location Default Action): Mention that
13112 YYLLOC_DEFAULT is also invoked for syntax errors.
13113 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
13114 Error locations include the locations of all the tokens that were
13115 discarded, not just the last token.

13119 * src/files.c: Include quote.h.
13120 (compute_output_file_names): Warn if we detect conflicting
13121 outputs to the same file. This should catch the misunderstanding
13122 exemplified by Debian Bug 165349, reported by Bruce Stephens..
13123
13124 * src/conflicts.c (conflicts_print): If the user specifies
13125 "%expect N", report an error if there are any reduce/reduce
13126 conflicts. This is what the manual says should happen.
13127 This fixes Debian bug 130890, reported by Anthony DeRobertis.

13137 * src/output.c (output_skeleton): Use full path names when
13138 specifying a file to include; don't rely on include path, as
13139 it's unreliable when the working file contains a file with
13140 that name.

13172 If the user does not define YYSTYPE as a macro, Bison now declares it
13173 using typedef instead of defining it as a macro. POSIX requires this.
13174 For consistency, YYLTYPE is also declared instead of defined.
13175
13176 %union directives can now have a tag before the `{', e.g., the
13177 directive `%union foo {...}' now generates the C code
13178 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
13179 The default union tag is `YYSTYPE', for compatibility with Solaris 9
13180 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
13181 instead of `yyltype'.
13182
13183 `yystype' and `yyltype' are now obsolescent macros instead of being
13184 typedefs or tags; they are no longer documented and will be
13185 withdrawn in a future release.
13186
13187 * data/glr.c (b4_location_type): Remove.
13188 (YYSTYPE): Renamed from yystype.
13189 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
13190 (struct YYLTYPE): Renamed from struct yyltype.
13191 (YYLTYPE): Renamed from yyltype.
13192 (yyltype, yystype): New (and obsolescent) macros,
13193 for backward compatibility.
13194 * data/yacc.c: Likewise.
13195
13196 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
13197 does not specify a union tag. This is for compatibility with
13198 Solaris 9 yacc.
13199
13200 * src/parse-gram.y (add_param): 2nd arg is now char * not char
13201 const *, since it is now modified by stripping surrounding { }.
13202 (current_braced_code): Remove.
13203 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
13204 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
13205 trailing " {...}". Now of type <chars>.
13206 (grammar_declaration): Adjust to bundled tokens.
13207 (code_content): Remove; stripping is now done by add_param.
13208 (print_token_value): Print contents of bundled tokens.
13209 (token_name): New function.
13210
13211 * src/reader.h (braced_code, current_braced_code): Remove.
13212 (token_name): New decl.
13213
13214 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
13215 token_type, not braced_code code_kind. All uses changed.
13216 (SC_PRE_CODE): New state, for scanning after a keyword that
13217 has (or usually has) an immediately-following braced code.
13218 (token_type): New local var, to keep track of which token type
13219 to return when scanning braced code.

13223 instead of returning a token type immediately.
13224 (<INITIAL>"{"): Set token type.
13225 (<SC_BRACED_CODE>"}"): Use it.
13226 (handle_action_dollar, handle_action_at): Now returns bool
13227 indicating success. Fail if ! current_rule; this prevents a core dump.
13228 (handle_symbol_code_dollar, handle_symbol_code_at):
13229 Remove; merge body into caller.
13230 (handle_dollar, handle_at): Complain in invalid contexts.

13289 Remove unportable casts and storage allocation tricks.
13290 While we're at it, remove almost all casts, since they
13291 usually aren't needed and are a sign of trouble.
13292
13293 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
13294
13295 * src/derives.c (derives_compute): Do not subtract NTOKENS from
13296 the pointer DSET returned by malloc; this isn't portable.
13297 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
13298 Similarly for DERIVES.
13299 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
13300 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.

13302
13303 * src/derives.c (derives_compute): Do not bother invoking
13304 int_of_rule_number, since rule numbers are integers.
13305
13306 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
13307 rather than XMALLOC (char, N).
13308
13309 * src/files.c (filename_split): Rewrite to avoid cast.
13310
13311 * src/gram.h (symbol_number_as_item_number,
13312 item_number_as_symbol_number, rule_number_as_item_number,
13313 item_number_as_rule_number):
13314 Now inline functions rather than macros, to avoid casts.
13315 * src/state.h (state_number_as_int): Likewise.
13316 * src/tables.c (state_number_to_vector_number,
13317 symbol_number_to_vector_number): Likewise.

13319 * src/gram.h (int_of_rule_number): Remove; no longer used.
13320
13321 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
13322 since the resulting storage is always stored into.
13323
13324 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
13325 where it's needed.
13326

13342 * src/uniqstr.c (uniqstr_print_processor): Likewise.
13343 * src/muscle_tab.c (muscles_m4_output):

13347 symbols_token_translations_init):

13349 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
13350
13351 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
13352 var instead of casting to long, to avoid casts.
13353 (prepare_states): Use MALLOC rather than alloca, so that we don't
13354 have to worry about alloca.
13355 * src/state.c (state_hash_lookup): Likewise.
13356
13357 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
13358 local var instead of casting to unsigned char, to avoid casts.
13359

13361 STATE_ALLOC): Remove.
13362 (transitions_new, errs_new, reductions_new, state_new): Use malloc
13363 rather than calloc, and use offsetof to avoid allocating slightly
13364 too much storage.
13365 (state_new): Initialize all members.
13366
13367 * src/state.c (state_hash): Use unsigned accumulator, not signed.
13368
13369 * src/symtab.c (symbol_free): Remove; unused.

13387 (table_grow, table_ninf_remap): Use signed table size.
13388 (save_row): Don't bother initializing locals when not needed.
13389 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
13390 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
13391
13392 * src/vcg.h: Correct misspellings.

14225 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
14226 escapes other than \\ and \'; this simplifies the code.

14228 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,

14233 them with auto vars.
14234 Switch to new escape scheme, where @ is the escape character uniformly.
14235 Abort if a stray escape character is found. Avoid unbounded input
14236 buffer when parsing non-escaped text.
14237

14251 counted in the token inserted at end of file. Now takes
14252 location_t *, not location_t, so that the location can be
14253 adjusted. All uses changed.

14273

14608
14609 Be consistent about 'bool'; the old code used an enum in one
14610 module and an int in another, and this violates the C standard.
14611 * m4/stdbool.m4: New file, from coreutils 4.5.3.
14612 * configure.ac (AC_HEADER_STDBOOL): Add.
14613 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
14614 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
14615 * src/symtab.c (hash_compare_symbol_t): Likewise.
14616 * src/system.h (bool, false, true): Use a definition consistent
14617 with ../lib/hash.c. All uses changed.
14618
14619 * src/complain.c (warning_issued): Renamed from warn_message_count,
14620 so that we needn't worry about integer overflow (!).
14621 Now of type bool. All uses changed.
14622 (complaint_issued): Renamed from complain_message_count; likewise.
14623
14624 * src/main.c (main): Use exit to exit with failure.

14636 What was that "2" for?
14637
14638 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
14639 * src/getargs.c (usage): Likewise.
14640
14641 * src/getargs.c (getargs): When there are too few operands, report
14642 the last one. When there are too many, report the first extra
14643 one. This is how diffutils does it.

14651 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
14652 fatal): Assume prototypes.
14653 * src/complain.h: Assume prototypes.
14654 * src/system.h (PARAMS): Remove.
14655 Include <limits.h> unconditionally, since it's guaranteeed even
14656 for a freestanding C89 compiler.
14657 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.

14721 Do not create a temporary file, as that involves security and
14722 cleanup headaches. Instead, use a pair of pipes.
14723 Derived from a suggestion by Florian Krohm.

14736 Check that m4sugar.m4 is readable, to avoid deadlock.
14737 Check for pipe I/O error.
14738 * src/scan-skel.l (readpipe): Remove decl.

14742 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
14743 float, as this generates a warning on Solaris 8 + GCC 3.2 with
14744 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
14745 this generates a more-accurate value anyway.
14746
14747 * lib/timevar.c (timervar_accumulate): Rename locals to
14748 avoid confusion with similarly-named more-global.

14783 * tests/calc.at: Use %locations, not --locations.
14784 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.

14789 accordingly.
14790 Report the traditional `Try ... --help' message when status != 0.
14791 (usage, version): Don't take a FILE * as arg, it is pointless.
14792 (getargs): When there is an incorrect number of arguments, make it

14832 Stop using the "enum_" trick for K&R-style function definitions;
14833 it confused me, and I was the author! Instead, assume that people
14834 who want to use K&R C compilers (when using these modules in GCC,

14967 Let nondeterministic skeletons be usable with deterministic
14968 tables.
14969
14970 With the patch, GAWK compiled by GCC without -O2 passes its test
14971 suite using a GLR parser driven by LALR tables. It fails with -O2
14972 because `struct stat' gives two different answers on my machine:
14973 88 (definition of an auto var) and later 96 (memset on this var).
14974 Hence the stack is badly corrumpted. The headers inclusion is to
14975 blame: if I move the awk.h inclusion before GLR's system header
14976 inclusion, the two struct stat have the same size.
14977
14978 * src/tables.c (pack_table): Always create conflict_table.

15015 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
15016 (which was a bug: it should have been YYTABEL_NINF, and yet it was
15017 not satisfying as we could compare an YYACTION computed from
15018 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
15019 only value for error actions.

15030 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
15031 because the Bison parser reads the second action before reducing
15032 the first one.
15033 * src/scan-gram.l (rule_length): New static var.
15034 Use it to keep track of the rule length in the scanner, since
15035 we can't expect the parser to be in lock-step sync with the scanner.

15450 functions are not portable. Do not assume size_t is the
15451 same width as int.

15453 as int, and similarly for yyposn and YYINDEX.
15454

15496 check for void *.
15497
15498 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
15499 size_t; the old version tried to do this but casted improperly.

15533 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
15534 manual recommends.
15535 Similarly, use src/scan-gram.l instead of src/scan-gram.c.

15538 (strerror): Use same pattern as ../lib/error.c.
15539
15540 * src/files.c, src/files.h (compute_header_macro): Remove; unused.

15543

15545 to void, to avoid a GCC warning when --disable-nls is in effect.
15546
15547 * src/scan-gram.l: Use strings rather than escapes when possible,
15548 to minimize the number of warnings from xgettext.
15549 (handle_action_dollar, handle_action_at): Don't use isdigit,
15550 as it mishandles negative chars and it may not work as expected
15551 outside the C locale.
15552
15553 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
15554 this is a GCC extension and is not portable to other compilers.

15557 Do not include <ctype.h>; no longer needed.
15558 Do not include <malloc.h>; no longer needed (and generates
15559 warnings on OpenBSD 3.0).
15560
15561 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
15562 it's not portable.
15563
15564 * tests/regression.at: Do not use 'cc -c input.c -o input';
15565 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
15566
15567 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
15568 exit status as failure, not just exit status 1. Sun C exits
15569 with status 2 sometimes.
15570

18418 * src/system.h: We don't need nor want bcopy.
18419 Throw away MS-DOS crap: we don't need getpid.
18420 * configure.in: We don't need strndup. It was even causing
18421 problems: because Flex includes the headers *before* us,
18422 _GNU_SOURCE is not defined by config.h, and therefore strndup was
18423 not visible.
18424 * lib/xstrndup.c: New.
18425 * src/scan-skel.l: Use it.
18426 Be sure to initialize yylval.muscle member when scanning a MUSCLE.

18440 Include skeleton.h.
18441 Don't use %option yylineno: it seems that then Flex imagines
18442 REJECT has been used, and therefore it won't reallocate its
18443 buffers (which makes no other sense to me than a bug). It results
18444 in warnings for `unused: yy_flex_realloc'.

18751 (generate_states): Adjust.
18752 * src/print.c: When reporting a rule number to the user, substract

18789 Be sure to preserve the value of the eoftoken.
18790 (reader): Make sure eoftoken is defined.
18791 Initialize nsyms to 0: now eoftoken is created just like the others.
18792 * src/print.c (print_grammar): Don't special case the eof token.
18793 * src/regression.at: Adjust: `$' has value 0, not -1, which was a

19637 Because useless nonterminals are now kept alive (instead of being
19638 `destroyed'), we now sometimes examine them, and store information
19639 related to them. Hence we need to know their number, and adjust

19646 the number of occurrences of each symbol, and later reassigned to
19647 `shift_symbol', containing the symbol that can be shifted from a
19648 given state.
19649 Deobfuscate, i.e., allocate, use and free `symbol_count' here
19650 only, and...
19651 (new_itemsets): Allocate `shift_symbol' here.
19652 (allocate_itemsets): symbol_count includes useless nonterminals.

22033 The location tracking mechanism is precious for parse error
22034 messages. Nevertheless, it is enabled only when `@n' is used in
22035 the grammar, which is a different issue (you can use it in error
22036 message, but not in the grammar per se). Therefore, there should
22037 be another means to enable it.

22069 Test also `--verbose', `--defines' and `--name-prefix'. Testing
22070 the latter demonstrates a flaw in the handling of non debugging
22071 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
22072 was used in order to simplify:
22073
22074 #if YYDEBUG
22075 if (yydebug)
22076 {
22077 ...
22078 }
22079 #endif

22081 into
22082
22083 if (yydebug)
22084 {
22085 ...
22086 }
22087
22088 unfortunately this leads to a CPP conflict when
22089 `--name-prefix=foo' is used since it produces `#define yydebug
22090 foodebug'.

22140 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
22141 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
22142 difficult and introduced a lot of core dump. It turns out that
22143 Bison used an implementation of `xmalloc' based on `calloc', and
22144 at various places it does depend upon the initialization to 0. I
22145 have not tried to isolate the pertinent places, and all the former
22146 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
