8 * doc/bison.texinfo (Bison Options): Document.
9 * src/complain.c, src/complain.h
10 (warn_at, warn_at_indent, warn): Suppress warning if -Wno-other.
11 (midrule_value_at): New warning function, similar to yacc_at in
12 that it's controlled by its own warning category.
13 * src/getargs.c (warnings_flag): Initialize to warnings_other.
14 (warnings_args, warnings_types): Add entry for warnings_other.
15 (usage): Update.
16 * src/getargs.h (enum warnings): Add entry for warnings_other.
17 * src/gram.c (grammar_rules_useless_report): If -Wno-other, then
18 don't print useless rules.
19 * src/reader.c (symbol_should_be_used): Rather than adjusting the
20 return value based on whether midrule value warnings are enabled,
21 accept a new parameter for telling the caller whether true is
22 being returned for a potential midrule warning.
23 (grammar_rule_check): Use midrule_value_at for midrule value
24 warnings, and continue to use warn_at for all other warnings. Let
25 them check whether the warnings are enabled.
26 * tests/local.at (AT_BISON_CHECK): Update documentation.
27 (AT_BISON_CHECK_NO_XML): Check that -Wnone and --warnings=none
28 disable all warnings exercised in the test suite.

152 doc: create a new Tuning LR section in the manual.
153 And clean up all other documentation of the features described
154 there.
155 * NEWS (2.5): Tweak wording of lr.type and parse.lac entries a
156 bit, update the cross-references to the manual, and point out that
157 LAC has caveats. Don't be so adamant that IELR+LAC=canonical LR.
158 That is, as the referenced section in the manual documents, LAC
159 does not fix infinite parsing loops on syntax errors.
160 * doc/bison.texinfo: Consistently drop the "(1)" suffix from LALR,
161 IELR, and LR in @cindex.
162 (%define Summary): Condense the entries for lr.default-reductions,
163 lr.keep-unreachable-states, lr.type, and parse.lac into brief

166 deterministic parsers in C.

254 doc: clean up naming of various Bison files.
255 The Bison manual's names for various files associated with a Bison
256 parser has devolved into inconsistency. This patch makes the
257 naming consistent for the most important files. First, it chooses
258 "grammar file" over "input file". The former appears to be more
259 traditional in the Bison manual, and Bison has other input
260 files (skeletons). Second, it chooses "parser implementation
261 file" over names like "parser file", "parser source file", "parser
262 source code file", and "parser output file". The new name makes
263 it clearer where Bison generates the main parser implementation,
264 and it is easily distinguishable from "parser header file".

279 LR(1) are experimental. Mention Java. Normally experimental
280 features probably shouldn't be mentioned in the introduction.
281 However, if Bison's limitations to LALR(1), C, and C++ are so
282 important that they should be mentioned here, then it's important
283 to point out that Bison is beginning to escape those limitations.
284 Moreover, these particular experimental features have very little
285 chance of being removed.

291 Do not allow identifiers that start with a dash.
292 This cleans up our previous fixes for a bug whereby Bison
293 discarded `.field' in `$-1.field'. The previous fixes were less
294 restrictive about where a dash could appear in an identifier, but
295 the restrictions were hard to explain. That bug was reported and
296 this final fix was originally suggested by Paul Hilfinger. This
297 also fixes a remaining bug reported by Paul Eggert whereby Bison
298 parses `%token ID -123' as `%token ID - 123' and handles `-' as an
299 identifier. Now, `-' cannot be an identifier. Discussed in
300 threads beginning at
301 <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00000.html>,
302 <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00004.html>.
303 * NEWS (2.5): Update entry describing the dash extension to
304 grammar symbol names. Also, move that entry before the named
305 references entry because the latter mentions the former.
306 * doc/bison.texinfo (Symbol): Update documentation for symbol
307 names. As suggested by Paul Eggert, mention the effect of periods
308 and dashes on named references.
309 (Decl Summary): Update documentation for unquoted %define values,
310 which, as a side effect, can no longer start with dashes either.

338 Improve error messages for `$' or `@' followed by `.' or `-'.
339 Previously, for this special case of an invalid reference, the
340 usual "symbol not found in production:" was printed. However,
341 because the symbol name was parsed as the empty string, that
342 message was followed immediately by a newline instead of a symbol
343 name. In reality, this is a syntax error, so the reference is
344 invalid regardless of the symbols actually appearing in the
345 production. Discussed at
346 <http://lists.gnu.org/archive/html/bison-patches/2011-01/msg00012.html>.
347 * src/scan-code.l (parse_ref): Report the above case as a syntax
348 error. Other than that, continue to handle this case like any
349 other invalid reference that Bison manages to parse because
350 "possibly meant" messages can still be helpful to the user.

434 parse.lac: implement exploratory stack reallocations.
435 * data/yacc.c: Rename %define variable parse.lac.es-capacity to
436 parse.lac.es-capacity-initial. Accept parse.lac.memory-trace
437 with values of "failures" (default) or "full".
438 (b4_declare_parser_state_variables): Add yyesa, yyes, and
439 yyes_capacity variables.
440 (YYSTACK_USE_ALLOCA): Ignore it if LAC requested.
441 (YYSTACK_ALLOC, YYSTACK_FREE, YYSTACK_ALLOC_MAXIMUM): Define if
442 LAC requested.
443 (YYCOPY_NEEDED): New cpp macro.
444 (YYCOPY): Define if LAC requested.
445 (yy_lac_stack_realloc): New function implementing stack
446 reallocations. Use YYMAXDEPTH for maximum stack size given that
447 the stack should never need to grow larger than the main state
448 stack needs to grow without LAC.
449 (YY_LAC_ESTABLISH): Update yy_lac invocation.
450 (yy_lac): Add arguments for exploratory stack memory data
451 recorded in the main parser. Invoke yy_lac_stack_realloc when
452 reallocation is necessary.
453 (yysyntax_error): Add the same new arguments and pass them to
454 yy_lac.
455 (yypstate_delete): Free yyes if necessary.
456 (yyesa, yyes, yyes_capacity): #define these to yypstate members
457 in the case of push parsing.
458 (yyparse, yypush_parse): Initialize yyes and yyes_capacity.
459 Update yysyntax_error invocations. At yyreturn, free yyes if
460 necessary.
461 * src/parse-gram.y: %define parse.lac full.
462 * tests/input.at (LAC: errors for %define): Extend for
463 parse.lac-memory-trace.
464 * tests/regression.at (LAC: Exploratory stack): Extend to check
465 that stack reallocs happen when expected.
466 (LAC: Memory exhaustion): Update to use YYMAXDEPTH and
467 parse.lac.es-capacity-initial.

471 parse.lac: implement as %define variable.
472 LAC = lookahead correction. See discussion at
473 <http://lists.gnu.org/archive/html/bison-patches/2009-09/msg00034.html>.
474 However, one point there must be corrected: because of %nonassoc,
475 LAC is *not* always redundant for lr.type=canonical-lr.
476 * data/yacc.c: Accept values of "none" (default) or "full" for
477 parse.lac. Accept %define parse.lac.es-capacity to specify
478 capacity of LAC's temporary exploratory stack. It defaults to 20
479 and, for now, will not grow dynamically.
480 (b4_lac_flag, b4_lac_if): New m4 macros. Evaluate as true for
481 parse.lac!=none.
482 (YYBACKUP): Invoke YY_LAC_DISCARD.
483 (YY_LAC_ESTABLISH, YY_LAC_DISCARD): New cpp macros that invoke
484 yy_lac and track when it needs to be invoked
485 (yy_lac): New function that, given the current stack, determines
486 whether a token can eventually be shifted. Return status mimics
487 yyparse return status.
488 (yysyntax_error): Change yystate argument to yyssp so stack top
489 can be passed to yy_lac. If LAC is requested, build expected
490 token list by invoking yy_lac for every token instead of just
491 checking the current state for lookaheads. Return 2 if yy_lac
492 exhausts memory.
493 (yyparse, yypush_parse): Use local variable yy_lac_established and
494 cpp macros YY_LAC_ESTABLISH and YY_LAC_DISCARD to implement LAC.
495 Update yysyntax_error invocation. Add yyexhaustedlab code if LAC
496 is requested.
497 * tests/conflicts.at (%nonassoc and eof): Extend to check the
498 effect of each of -Dlr.type=canonical-lr and -Dparse.lac=full.
499 (%error-verbose and consistent errors): Likewise.
500 (LAC: %nonassoc requires splitting canonical LR states): New test
501 group demonstrating how LAC can fix canonical LR.
502 * tests/input.at (LAC: Errors for %define): New test group.
503 * tests/regression.at (LAC: Exploratory stack): New test group.
504 (LAC: Memory exhaustion): New test group.

517 yysyntax_error: adjust prior fixes for branch-2.5's lalr1.cc.
518 On master, there is no yychar in lalr1.cc, but there is on
519 branch-2.5, and the prior cherry-pick of "Fix handling of yychar
520 manipulation in user semantic actions" wasn't adjusted for that
521 difference.
522 * data/lalr1.cc (yy::parser::parse): Translate yychar before
523 every use of yytoken, and add comments explaining this approach.
524 * tests/conflicts.at (%error-verbose and consistent errors):
525 Extend to test yychar manipulation with lalr1.cc.

529 yysyntax_error: fix for consistent error with lookahead.
530 * NEWS (2.5): Document.
531 * data/yacc.c (yysyntax_error): In a verbose syntax error
532 message while in a consistent state with a default action (which
533 must be an error action given that yysyntax_error is being
534 invoked), continue to drop the expected token list, but don't
535 drop the unexpected token unless there actually is no lookahead.
536 Moreover, handle that internally instead of returning 1 to tell
537 the caller to do it. With that meaning of 1 gone, renumber
538 return codes more usefully.
539 (yyparse, yypush_parse): Update yysyntax_error usage. Most
540 importantly, set yytoken to YYEMPTY when there's no lookahead.
541 * data/glr.c (yyreportSyntaxError): As in yacc.c, don't drop the
542 unexpected token unless there actually is no lookahead.
543 * data/lalr1.cc (yy::parser::parse): If there's no lookahead,
544 set yytoken to yyempty_ before invoking yysyntax_error_.
545 (yy::parser::yysyntax_error_): Again, don't drop the unexpected
546 token unless there actually is no lookahead.
547 * data/lalr1.java (YYParser::parse): If there's no lookahead,
548 set yytoken to yyempty_ before invoking yysyntax_error.
549 (YYParser::yysyntax_error): Again, don't drop the unexpected
550 token unless there actually is no lookahead.
551 * tests/conflicts.at (%error-verbose and consistent
552 errors): Extend test group to further reveal how the previous
553 use of the simple "syntax error" message was too general. Test
554 yacc.c, glr.c, lalr1.cc, and lalr1.java. No longer an expected
555 failure.
556 * tests/java.at (AT_JAVA_COMPILE, AT_JAVA_PARSER_CHECK): Move
557 to...
558 * tests/local.at: ... here.
559 (_AT_BISON_OPTION_PUSHDEFS): Push AT_SKEL_JAVA_IF definition.
560 (AT_BISON_OPTION_POPDEFS): Pop it.
561 (AT_FULL_COMPILE): Extend to handle Java.

628 installed just for us.

630 glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now
631 needed somehow. Don't have time to look into why.
632 (gnulib_modules): Change malloc to malloc-gnu. Do we really assume
633 the GNU malloc behavior, where malloc (0) != NULL unless we're
634 out of storage? If not, we can omit malloc-gnu; but for now I left
635 it in to be safe.
636 (vc_ignore): Remove.

638 uses that convention.

1039 portability: fix several issues with M4 subprocess.
1040
1041 M4's output pipe was not being drained upon fatal errors during
1042 scan_skel. As a result, broken-pipe messages from M4 were seen
1043 on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
1044 failure in the test suite. The problem was that, on platforms
1045 where the default disposition for SIGPIPE is ignore instead of
1046 terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
1047 then reported it. However, there's some sort of race condition,
1048 because the new test group occasionally succeeded.

1253 Fix handling of yychar manipulation in user semantic actions.
1254 The problem was that yacc.c didn't always update the yychar
1255 translation afterwards. However, other skeletons appear to be
1256 fine. glr.c appears to already translate yychar before every
1257 use. lalr1.cc does not define yychar and does not document its
1258 replacement, yyla, for users. It does provide yyclearin, but
1259 that does not manipulate yyla and thus requires no translation
1260 update. In lalr1.java, yychar is out of scope during semantic
1261 actions.
1262 * NEWS (2.5): Document.
1263 * data/yacc.c (YYBACKUP): Don't bother translating yychar into
1264 yytoken here.
1265 (yyparse, yypush_parse): Instead, translate before every use of
1266 yytoken, and add comments explaining this approach.
1267 * tests/actions.at (Destroying lookahead assigned by semantic
1268 action): New test group checking that translation happens before
1269 lookahead destructor calls at parser return. Previously,
1270 incorrect destructors were called.
1271 * tests/conflicts.at (%error-verbose and consistent
1272 errors): New test group checking that translation happens at
1273 syntax error detection before the associated verbose error
1274 message and the associated lookahead destructor calls. While
1275 the destructor call is fixed by this patch, the verbose error
1276 message is currently incorrect due to another bug (see
1277 comments in test group), so this is an expected failure for now.

1456 yysyntax_error: avoid duplicate lookahead collection.
1457 Except when memory reallocation is required, this change
1458 eliminates the need to invoke yysyntax_error twice and thus to
1459 repeat the collection of lookaheads. It also prepares for
1460 future extensions that will make those repetitions more

1717 (yygetLRActions): Check for default value from yypact. It
1718 appears that this check is always performed before this function

1720 However, the code may evolve after this subtlety is forgotten.
1721 Also, update for rename to yytable_value_is_error. Because that
1722 macro now checks for zero, a different but equivalent branch of

1803 For a \0 and similar escape sequences meaning the null
1804 character, report an invalid escape sequence instead of an
1805 invalid null character because the latter does not actually

1807 In all escape sequence complaints, don't escape the initial
1808 backslash, and don't quote when the sequence appears at the end
1809 of the complaint line unless there's whitespace that quotearg
1810 won't escape.
1811 Consistently say "invalid" not "unrecognized".
1812 Consistently prefer "empty character literal" over "extra
1813 characters in character literal" warning for invalid escape
1814 sequences; that is, consistently discard those sequences.

3519 * tests/regression.at (Token definitions): Because of the change in
3520 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
3521 escapes trigraphs in symbol names. Thus, yytname no longer has
3522 trigraphs unnecessarily doubly escaped. Update test case output.

4650 * src/lalr.c (state_lookahead_tokens_count): For code readability,
4651 move the check for disabled transitions to an aver since conflict
4652 resolution hasn't happened yet.
4653
4654 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
4655 labels a state as inconsistent just because it has error transitions.
4656 The original form of this check appeared in revision 1.1 of lalr.c,
4657 which was committed on 1991-12-21. Now (at least), changing the
4658 consistency label on such a state appears to have no useful effect in
4659 any of the places it is examined, which I enumerate below. The key
4660 point to understanding each item in this enumeration is that a state
4661 with an error transition is labelled consistent in the first place only
4662 if it has no rules, so the check cannot matter for states that have
4663 rules. (1) Labelling a state as inconsistent will cause set_conflicts
4664 to try to identify its conflicts, and a state must have *rules* to have
4665 conflicts. (2) Labelling a state as inconsistent will affect how
4666 action_row sets the default *rule* for the state. (3) Labelling a
4667 state as inconsistent will cause build_relations to add lookback edges
4668 to *rules* in that state.

4670 more carefully.

5308 Instead of having skeletons declare all valid %define variables and
5309 %code qualifiers, provide macros that retrieve the associated values
5310 and build these lists automatically. Thus Bison will now warn when a
5311 variable or qualifier is not used by the skeleton in the current
5312 invocation regardless of whether it might sometimes be used by that
5313 skeleton in other invocations. Also, move all %define value macros to

5608 Encapsulate code properties and related functionality for the various
5609 destructors, printers, and actions into a code_props structure and
5610 interface. This patch merely implements code_props in scan-code.h and
5611 scan-code.l. Future patches will rewrite other modules to use it.
5612 Discussed starting at
5613 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
5614 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
5615 consistently initialize const structs that have an empty location
5616 field.
5617 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
5618 to ensure consistency.
5619 * src/scan-code.h (code_props): New structure.
5620 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
5621 function, macro, and const global variable for initializing a
5622 code_props with no code.
5623 (code_props_plain_init, code_props_symbol_action_init,
5624 code_props_rule_action_init, code_props_translate_code): The rest of
5625 the new code_props functional interface. Among other things, the init
5626 functions set the code_props kind field so that
5627 code_props_translate_code will know whether to behave like
5628 translate_symbol_action, translate_rule_action, or translate_code.
5629 These old translate functions must remain until all other modules are
5630 updated to use the new code_props interface.
5631 (code_scanner_last_string_free): New function similar to
5632 gram_scanner_last_string_free.
5633 (code_scanner_free): Add documentation.
5634 * src/scan-code.l: Implement the new interface.
5635 (code_lex): Make it static, add a code_props* argument, and remove the
5636 rule argument.
5637 (last_string): New static global similar to the one in scan-gram.l.
5638 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
5639 instead of rule.
5640 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
5641 code_props since Bison may one day use this information for destructors
5642 and printers.
5643 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
5644 (handle_action_dollar): Use symbol_list_n_get and set used flag
5645 directly since symbol_list_n_used_set is removed.
5646 (translate_action): Add a code_props* argument and remove the rule,
5647 action, and location arguments. Pass the code_props* on to code_lex.
5648 (translate_rule_action, translate_symbol_action, translate_code):
5649 Rewrite as wrappers around the new code_props interface.
5650 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
5651 it would eventually need to break the encapsulation of code_props.

5663 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
5664 appropriately based on their existing values.
5665 (yypush_parse): Don't print push-parser-specific diagnostics if push
5666 parsing is being used in place of pull parsing.
5667 * data/yacc.c: If push parsing should replace pull parsing, redirect to
5668 push.c.

5676 (whether successful or failed) so that yypush_parse can be invoked
5677 again to start a new parse using the same yypstate.
5678 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
5679 check multiple yypull_parse invocations on the same yypstate. For pull
5680 mode, extend to check multiple yyparse invocations.

5688 declarations. Otherwise, this test case can't be used to see if push
5689 mode can truly emulate pull mode.

5691 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
5692 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
5693 AT_YACC_IF, which now includes the case of push mode since %skeleton
5694 need not be used for push mode. This will be more intuitive once
5695 push.c is renamed to yacc.c.

5699 For push mode, convert yyparse from a macro to a function, invoke yylex
5700 instead of passing a yylexp argument to yypull_parse, and don't
5701 generate yypull_parse or yyparse unless %push-pull-parser is declared.
5702 Discussed starting at
5703 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
5704 * data/bison.m4 (b4_pull_if): New.

5706 * data/push.c: Improve M4 quoting a little.
5707 (b4_generate_macro_args, b4_parenthesize): Remove.
5708 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
5709 any time a pull parser is requested.
5710 Don't #define this as a wrapper around yypull_parse. Instead, when
5711 both push and pull are requested, make it a function that does that
5712 same thing.
5713 (yypull_parse): If there's a b4_prefix, #define this to
5714 b4_prefix[pull_parse] when both push and pull are requested.
5715 Don't define this as a function unless both push and pull are
5716 requested.
5717 Remove the yylexp argument and hard-code yylex invocation instead.
5718 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
5719 %push-parser.
5720 * src/getargs.c (pull_parser): New global initialized to true.
5721 * getargs.h (pull_parser): extern it.

5725 %push-pull-parser. Set push_parser = true and pull_parser = false for
5726 %push-parser.
5727 * src/scan-gram.l: Don't accept %push_parser as an alternative to
5728 %push-parser since there's no backward-compatibility concern here.
5729 Scan %push-pull-parser.

5740 deserves most of the credit).
5741 * Makefile.am (SUBDIRS): Add etc subdirectory.

5743 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
5744 yytoken, yyval, and yyloc declarations to...
5745 (yyparse or yypush_parse): ... here to improve performance. For
5746 yypush_parse invocations after the first, be sure to assign yyn its old
5747 value again.
5748 (yypstate_new): Don't bother initializing the yyresult field since the
5749 initial value isn't used.
5750 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
5751 remove the #define that, in push mode, set it to yyps->NAME.
5752 * etc/Makefile.am: New.
5753 * etc/bench.pl: Remove and build it instead from...
5754 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
5755 "tests/bison" from the build directory by default rather than just
5756 invoking "bison" from $PATH.

5758 don't define yyparse_wrapper, and don't #define yyparse.

5777 Enable push parsers to operate in impure mode. Thus, %push-parser no
5778 longer implies %pure-parser. The point of this change is to move
5779 towards being able to test the push parser code by running the entire
5780 test suite as if %push-parser had been declared.
5781 * data/push.c (yypush_parse): For impure mode, remove the
5782 yypushed_char, yypushed_val, and yypushed_loc arguments.
5783 Instead, declare these as local variables initialized to the global
5784 yychar, yylval, and yylloc.
5785 For the first yypush_parse invocation only, restore the initial values
5786 of these global variables when it's time to read a token since they
5787 have been overwritten.
5788 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
5789 %push-parser.
5790 * tests/calc.at (Simple LALR(1) Calculator): Always declare
5791 %pure-parser along with %push-parser since this test case was designed
5792 for pure push parsers.
5793 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
5794 (AT_YACC_OR_PUSH_IF): New.
5795 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
5796 add a note that it's still wrong for some cases (as it has been for a
5797 while).
5798 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since

5832 Rearrange initialization of the parser state variables so that the
5833 skeleton doesn't have to have a copy for pull mode and another for push
5834 mode. This patch also fixes at least a bug such that yylloc was not
5835 initialized (with b4_location_initial_line and
5836 b4_location_initial_column) upon calling yypush_parse. However, that
5837 initialization now overwrites the first token's location;
5838 %initial-action assigning @$ already did the same thing, and both bugs
5839 will be fixed in a later patch.
5840 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.

5846 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
5847 yyps->NAME so it can be used in yypush_parse.
5848 (yyparse or yypush_parse): For yypush_parse, don't print the
5849 "Starting parse" diagnostic for invocations after the first.
5850 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
5851 yypush_parse, only do it for the first invocation.
5852 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc

5867 Encapsulate the push parser state variables into an M4 macro so the

5869 For push mode, remove yypush_parse's local equivalents of these
5870 variables to eliminate unnecessary copying between the two sets at
5871 run-time. This patch also fixes at least a bug related to multiple
5872 %initial-action invocations in push mode.

5882 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,

6043 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
6044 `bison ', use m4_index instead of m4_substr since chopping up a string
6045 containing M4-special characters causes problems here.
6046
6047 Fix a couple of bugs related to special characters in user-specified
6048 file names, and make it easier for skeletons to compute output file
6049 names with the same file name prefix as Bison-computed output file
6050 names.
6051 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
6052 b4_parser_file_name and b4_spec_defines_file instead of
6053 @output_parser_name@ and @output_header_name@, which are now redundant.
6054 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
6055 b4_parser_file_name, b4_spec_defines_file, and the new
6056 @basename(FILENAME@) instead of @output_parser_name@ and
6057 @output_header_name@, which inappropriately escaped the file names as
6058 C string literals.

6063 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
6064 exactly what MUSCLE_INSERT_STRING used to do.
6065 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
6066 characters are escaped properly.
6067 * src/output.c (prepare): Define muscle file_name_all_but_ext as
6068 all_but_ext.
6069 For pkgdatadir muscle, maintain previous functionality by using
6070 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
6071 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
6072 digraphs would never be expanded. Hopefully no one has M4-special
6073 characters in his Bison installation path.
6074 * src/scan-skel.l: Don't parse @output_header_name@ and
6075 @output_parser_name@ anymore since they're now redundant.
6076 In @output, use decode_at_digraphs.

6381 SYMLIST_DEFAULT_TAGLESS.
6382 * src/symlist.h: Update symbol_list_default*_new prototypes.

6409 Don't apply the default %destructor/%printer to an unreferenced midrule
6410 value. Mentioned at
6411 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
6412 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
6413 like $@n instead of just @n so that the default %destructor/%printer
6414 logic doesn't see them as user-defined symbols.
6415 (symbol_is_dummy): Check for both forms of the name.

6417 name for which the midrule value is referenced in any action.

6428 (packgram): Before invoking grammar_rule_check on any rule, make sure
6429 all actions have already been scanned in order to set `used' flags.
6430 Otherwise, checking that a midrule's $$ is set will not always work
6431 properly because the midrule check must forward-reference the midrule's
6432 parent rule.

6943 Whether the default %destructor/%printer applies to a particular symbol
6944 isn't a question of whether the user *declares* that symbol (in %token,
6945 for example). It's a question of whether the user by any means
6946 *defines* the symbol at all (by simply using a char token, for
6947 example). $end is defined by Bison whereas any other token with token
6948 number 0 is defined by the user. The error token is always defined by
6949 Bison regardless of whether the user declares it with %token, but we
6950 may one day let the user define error as a nonterminal instead.

7163 Clean up handling of %destructor for the end token (token 0).

7167 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
7168
7169 Make the skeletons consistent in how they pop the end token and invoke
7170 its %destructor.
7171 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
7172 state, which has token number 0, since this would invoke the
7173 %destructor for the end token.
7174 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
7175 until after shifting the end token, or else it won't be popped.
7176 * data/yacc.c (yyparse): Likewise.
7177
7178 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
7179 it's the end token. Upon termination, destroy an unshifted lookahead
7180 even when it's the end token.
7181 * data/lalr1.cc (yy::parser::parse): Likewise.
7182 * data/yacc.c (yyparse): Likewise.
7183
7184 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
7185 value warnings for the end token when the user gives the end token a
7186 %destructor.

7199 rejects them.
7200 Don't use autoreconf; instead, invoke autopoint etc. by hand,
7201 so that we can remove the intl files at a better time.
7202 (intl_files_to_remove): Remove aclocal.m4, since it gets
7203 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
7204 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,

7208 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
7209 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
7210 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
7211 strdup.h.

7521 Fix bug that mistakes braced code in a declaration in the rules section
7522 to be a rule action. Mentioned at
7523 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
7524 * src/scan-gram.l: Move midrule action detection from the start of the
7525 scanning of any braced code to...
7526 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
7527 action. For readability, use $2 and @2 rather than the equivalent
7528 global variables.
7529 * tests/regression.at (Braced code in declaration in rules section):
7530 New test to catch the error fixed by the above patch.
7531
7532 Work on code readability some.
7533 * src/scan-code.l (current_rule): Get rid of this misleading and
7534 redundant declaration: it's actually extern'ed in reader.h.

7536 translate_action): Add a rule argument and use it instead of the global
7537 current_rule.

7539 argument, so pass it on to translate_action instead of assigning
7540 current_rule to current_rule.

8011 Also, the embedded comments in this test case claim it checks the case
8012 of an empty RHS that has inherited the initial location. However, the
8013 corresponding LHS was already resolved, so yyresolveLocations didn't
8014 actually have reason to modify it. Fix this by forcing
8015 nondeterministic operation at the beginning of the parse.

8308 Remove the yyvalp and yylocp parameters since they are always just
8309 taken from the yys parameter. When reporting a discarded merged value
8310 in debugging output, note that it is incompletely merged. Document the
8311 interface.
8312 (yyresolveAction): If resolving any of the RHS states fails, destroy
8313 them all rather than leaking them. Thus, as long as user actions are
8314 written to clean up the RHS correctly, yyresolveAction always cleans up
8315 the RHS of a semantic option. Document the interface.

8732 In the yychar entry, remove mention of the local yychar case (pure
8733 parser) since this is irrelevant information when writing semantic

8759 Allocate, deallocate, resize, and otherwise shuffle space for
8760 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
8761 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
8762 appropriately during nondeterministic operation.
8763 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
8764 members to store the current lookahead to be used by the deferred
8765 user action.
8766 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
8767 from which the RHS is taken. Set the lookahead members of the new
8768 yySemanticOption according to the lookahead status for stack yyk.
8769 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
8770 yyaddDeferredAction.

8772 members of yySemanticOption before invoking yyuserAction, and then set

8777 titles for consistency.

8798 * data/glr.c (yyresolveValue): When merging semantic options, if at
8799 least one user action succeeds but a later one cuts the parse, then
8800 destroy the semantic value before returning rather than leaking it.
8801 (yyresolveStates): If a user action cuts the parse and thus
8802 yyresolveValue fails, ignore the (unset) semantic value rather than
8803 corrupting the yyGLRState, and empty the semantic options list since
8804 the user actions should have called all necessary destructors.
8805 Simplify code with YYCHK.

8807 cuts parse): New test case.

9108 Work around portability problem on Solaris 10: flex-generated
9109 files include <stdio.h> before <config.h>, which messes up
9110 because the latter defines __EXTENSIONS__. Address the problem

9488 Use unlocked I/O for a minor performance improvement on hosts like
9489 GNU/Linux and Solaris that support unlocked I/O. The basic idea

9938 uses 'echo', and 'echo' isn't portable if its argument contains
9939 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
9940 that the byte '\0xff' is not printable in the C locale; it is,
9941 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
9942 not printable, so use '\0x81' to test.

9999 it's error-prone and "make maintainer-distcheck" rejects it.

10021 * src/output.c: Include scan-skel.h.
10022 (scan_skel): Remove decl, since scan-skel.h does this.
10023 (output_skeleton):
10024 Indent calls to "error" to pacify "make maintainer-distcheck".
10025 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.

10040 "make maintainer-distcheck" complained about.
10041
10042 * examples/extexi (message): Don't print a message more than once,
10043 and omit line-number decoration that makes Emacs compile think
10044 that informative messages are worth worrying about.

10051 accidentally.
10052 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
10053 autogenerated by the maintainer.
10054 * examples/calc++/.cvsignore: Add *.yy.
10055

10069 the new runtime-po domain, prime the pump by extracting the
10070 relevant strings from the obsolete translations. This code can be
10071 removed once the bison-runtime domain has been translated by each
10072 team.
10073
10074 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
10075 now that token names are already quoted.

10098 * doc/bison.texinfo (Decl Summary, Calling Convention):
10099 Clarify quoting convention of yytname.
10100 * src/output.c (prepare_symbols): Quote all names. This undoes
10101 the 2005-04-17 change, which is now accomplished (mostly) via
10102 changes in the parsers as described above.
10103 * tests/regression.at (Token definitions, Web2c Actions):
10104 Undo most 2005-04-17 change here, too.

10108 Fix more problems reported by twlevo@xs4all.nl.
10109 * tests/cxx-type.at: Don't pipe output of ./types through sed to
10110 remove trailing spaces. This loses the exit status of ./types,
10111 and isn't needed since ./types shouldn't be emitting trailing
10112 spaces.
10113 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
10114 as the stack isn't valid in that case.

10127 overly-picky compilers that reject 'char *foo = "bar";'.
10128
10129 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
10130 to FILE * parameter, not to stderr. This fixes a typo introduced
10131 in the 2005-07-12 change.

10171 Rename yyoverflowab to yyexhaustedlab.
10172 When memory exhaustion occurs during syntax-error reporting,
10173 report it separately rather than in a single diagnostic; this
10174 eases translation.

10185 can be understood only by someone who can read the
10186 (English-language) source code.

10188 Generate runtime-po/bison-runtime.pot automatically, so that we

10191 get lost. See

10193
10194 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
10195 Now auto-generated.
10196 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
10197 Fix typos in explanations of the runtime file.
10198 * bootstrap: Change gettext keyword from YYI18N to YY_.
10199 Use standard Makefile.in.in in runtime-po, since we'll arrange
10200 for backward-compatible bison-runtime.po files in a different way.
10201 * data/glr.c (YY_): New macro, from yacc.c.
10202 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
10203 Translate messages intended for users.
10204 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
10205 the wording in the other skeletons. We don't know that the memory
10206 is virtual.
10207 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
10208 Use same method that yacc.c uses.
10209 Don't translate debugging messages.
10210 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
10211 it doesn't work (yet), and requires C++ expertise to fix.
10212 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
10213 Move defn to a more logical place, to be consistent with other
10214 skeletons.
10215 Don't translate debugging messages.
10216 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
10217 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
10218 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
10219 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

10238 struct.

10242 if YYABORT is used).

11015 Remove uses of 'short int' and 'unsigned short int'. This raises
11016 some arbitrary limits. It uses more memory but nowadays that's
11017 not much of an issue.

11019 This change does not affect the generated parsers; that's a different
11020 task, as some users will want to conserve memory there.

11423 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
11424 whether the reducion was empty or not. This leaves room to
11425 improve the use of YYLLOC_DEFAULT in such a case.
11426 lalr1.cc is still experimental, so changing this is acceptable.
11427 And finally, there are probably not many users who changed the
11428 handling of locations in GLR, so changing is admissible too.

11574 Bison directive from the Bison file to the invocation of this
11575 macro, so that these directives are passed to
11576 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
11577 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
11578 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
11579 the extra Bison directives instead of the whole series.
11580 Change the grammar so that there are recoverable errors, and
11581 unrecoverable errors. Now we can have the parser give up before
11582 consuming the whole input. As a result we now can observe that
11583 the lookahead is freed when needed.
11584 Change the parser source to parse argv[1] instead of a hard coded
11585 string.
11586 Simplify yylex, and give a value and location to EOF.
11587 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
11588 passed directives already coded in the file.
11589 Add some tests to check the location of "error".
11590 For some tests, the C++ parser is correct, and not yacc.c.
11591 For other tests, they provide different, but unsatisfying, values,
11592 so keep the C++ value so that at least one parser is "correct"
11593 according to the test suite.
11594 (Actions after errors): Remove, this is subsumed by the
11595 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

11773 Spent a few hours checking out which prerequisite versions the
11774 current sources actually require. I went all the way back to
11775 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
11776 a seemingly endless set of combinations of versions more recent
11777 than that. The bottom line is that the current sources require
11778 fairly recent versions of the build tools, and it'll be some work
11779 to change this.
11780 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
11781 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.

12592 Fix a GLR parser bug I reported in February; see

26ec81e0

12594 The problem was that GLR parsers did not conform to the C standard,
12595 because actions like { $1 = $2 + $3; } expanded to expressions
12596 that invoked YYFILL in separate subexpressions, and YYFILL assigned
12597 to a local variable. The C standard says that expressions
12598 like (var = f ()) + (var = f ()) have undefined behavior.
12599 Another problem was that GCC sometimes issues warnings that
12600 yyfill and its parameters are unused.
12601
12602 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
12603 as possibly unused.
12604 (yyfill): New function.
12605 (YYFILL): Use it.
12606 (yyuserAction): Change type of yynormal to bool, so that it matches
12607 the new yyfill signature. Mark it as possibly unused.
12608
12609
12610 Follow up on a bug I reported in February, where a Bison-generated
12611 parser can loop. Provide a test case and a fix for yacc.c. I
12612 don't have a fix for lalr1.cc or for glr.c, unfortunately.
12613 The original bug report is in:

12615
12616 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
12617 macro's size was becoming unwieldy.
12618 (yyerrlab): Do not discard an empty lookahead symbol, as this
12619 might destroy garbage.
12620 (yyerrorlab): New label, with the old contents of YYERROR,
12621 plus the following change: pop the stack of rhs corresponding
12622 to the production that invoked YYERROR. That is how Yacc
12623 behaves, and POSIX requires this behavior.
12624 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
12625 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
12626 Define 'alarm' to do nothing if unistd.h is not available.
12627 Add a new rule "exp: '-' error;" to test the above change to
12628 data/yacc.c. Use 'alarm' to abort any test taking longer than
12629 10 seconds, as it's probably looping.
12630 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
12631 Also, the new yacc.c generates two fewer diagnostics for an
12632 existing test.

13260 we don't need to worry about yyerrlab1 being reported as an

13262 locations are used then a couple of statements are duplicated each
13263 time YYERROR is invoked, but the upside is that the warnings
13264 should vanish.
13265 (yyerrlab1): Move code to YERROR.

13282 popped). This means that the initial elements will not be freed
13283 explicitly, as is the case in yacc.c; it is not a problem, as
13284 these elements have fake values.

13400 (conflicts_output): Use Yacc-style conflict report for each state,

13421 * data/yacc.c (yyparse): New local var yylerrsp, to record the
13422 top of the location stack's error locations.
13423 (yyerrlab): Set it. When discarding a token, push its location
13424 onto yylerrsp so that we don't lose track of the error's end.
13425 (yyerrlab1): Now is only the target of YYERROR, so that we can
13426 properly record the location of the action that failed. For GCC
13427 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
13428 GCC warning about yyerrlab1 being unused if YYERROR is unused.
13429 (yyerrlab2): New label, which yyerrlab now falls through to.
13430 Compute the error's location by applying YYLLOC_DEFAULT to
13431 the locations of all the symbols that went into the error.
13432 * doc/bison.texinfo (Location Default Action): Mention that
13433 YYLLOC_DEFAULT is also invoked for syntax errors.
13434 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

13483 Version 1.75e.

13485 * Makefile.maint (cvs-update): Don't assume that the shell
13486 supports $(...), as Solaris sh doesn't.
13487
13488 * src/parse-gram.y (lloc_default): Remove test for empty
13489 nonterminals at the end, since it didn't change the result.

13493 If the user does not define YYSTYPE as a macro, Bison now declares it
13494 using typedef instead of defining it as a macro. POSIX requires this.
13495 For consistency, YYLTYPE is also declared instead of defined.
13496
13497 %union directives can now have a tag before the `{', e.g., the
13498 directive `%union foo {...}' now generates the C code
13499 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
13500 The default union tag is `YYSTYPE', for compatibility with Solaris 9
13501 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
13502 instead of `yyltype'.
13503
13504 `yystype' and `yyltype' are now obsolescent macros instead of being
13505 typedefs or tags; they are no longer documented and will be
13506 withdrawn in a future release.
13507
13508 * data/glr.c (b4_location_type): Remove.
13509 (YYSTYPE): Renamed from yystype.
13510 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
13511 (struct YYLTYPE): Renamed from struct yyltype.
13512 (YYLTYPE): Renamed from yyltype.
13513 (yyltype, yystype): New (and obsolescent) macros,
13514 for backward compatibility.
13515 * data/yacc.c: Likewise.
13516
13517 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
13518 does not specify a union tag. This is for compatibility with
13519 Solaris 9 yacc.
13520
13521 * src/parse-gram.y (add_param): 2nd arg is now char * not char
13522 const *, since it is now modified by stripping surrounding { }.
13523 (current_braced_code): Remove.
13524 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
13525 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
13526 trailing " {...}". Now of type <chars>.
13527 (grammar_declaration): Adjust to bundled tokens.
13528 (code_content): Remove; stripping is now done by add_param.
13529 (print_token_value): Print contents of bundled tokens.
13530 (token_name): New function.
13531
13532 * src/reader.h (braced_code, current_braced_code): Remove.
13533 (token_name): New decl.
13534
13535 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
13536 token_type, not braced_code code_kind. All uses changed.
13537 (SC_PRE_CODE): New state, for scanning after a keyword that
13538 has (or usually has) an immediately-following braced code.
13539 (token_type): New local var, to keep track of which token type
13540 to return when scanning braced code.

PE
13543 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
13544 instead of returning a token type immediately.
13545 (<INITIAL>"{"): Set token type.
13546 (<SC_BRACED_CODE>"}"): Use it.
13547 (handle_action_dollar, handle_action_at): Now returns bool
13548 indicating success. Fail if ! current_rule; this prevents a core dump.
13549 (handle_symbol_code_dollar, handle_symbol_code_at):
13550 Remove; merge body into caller.
13551 (handle_dollar, handle_at): Complain in invalid contexts.

13610 Remove unportable casts and storage allocation tricks.
13611 While we're at it, remove almost all casts, since they
13612 usually aren't needed and are a sign of trouble.
13613
13614 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
13615
13616 * src/derives.c (derives_compute): Do not subtract NTOKENS from
13617 the pointer DSET returned by malloc; this isn't portable.
13618 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
13619 Similarly for DERIVES.
13620 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
13621 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
13622 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
13623
13624 * src/derives.c (derives_compute): Do not bother invoking
13625 int_of_rule_number, since rule numbers are integers.
13626
13627 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
13628 rather than XMALLOC (char, N).
13629
13630 * src/files.c (filename_split): Rewrite to avoid cast.
13631
13632 * src/gram.h (symbol_number_as_item_number,
13633 item_number_as_symbol_number, rule_number_as_item_number,
13634 item_number_as_rule_number):
13635 Now inline functions rather than macros, to avoid casts.
13636 * src/state.h (state_number_as_int): Likewise.
13637 * src/tables.c (state_number_to_vector_number,
13638 symbol_number_to_vector_number): Likewise.

13640 * src/gram.h (int_of_rule_number): Remove; no longer used.
13641
13642 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
13643 since the resulting storage is always stored into.
13644
13645 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
13646 where it's needed.
13647
13648 * src/muscle_tab.c (muscle_m4_output):
13649 Now inline. Return bool, not int.
13650 * src/state.c (state_compare): Likewise.

13656 * src/muscle_tab.c (muscle_m4_output_processor):
13657 New function, to avoid casts.

13660 symbol_check_alias_consistency_processor, symbol_pack_processor,
13661 symbol_translation_processor, hash_symbol_comparator,
13662 hash_symbol_hasher): Likewise.
13663 * src/uniqstr.c (uniqstr_print_processor): Likewise.
13664 * src/muscle_tab.c (muscles_m4_output):
13665 Use new functions instead of casting old functions unportably.

13668 symbols_token_translations_init):
13669 Likewise.
13670 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
13671
13672 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
13673 var instead of casting to long, to avoid casts.
13674 (prepare_states): Use MALLOC rather than alloca, so that we don't
13675 have to worry about alloca.
13676 * src/state.c (state_hash_lookup): Likewise.
13677
13678 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
13679 local var instead of casting to unsigned char, to avoid casts.
13680
13681 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
13682 STATE_ALLOC): Remove.
13683 (transitions_new, errs_new, reductions_new, state_new): Use malloc
13684 rather than calloc, and use offsetof to avoid allocating slightly
13685 too much storage.
13686 (state_new): Initialize all members.
13687
13688 * src/state.c (state_hash): Use unsigned accumulator, not signed.
13689
13690 * src/symtab.c (symbol_free): Remove; unused.
13691 (symbol_get): Remove cast in lhs of assignment.
13692 (symbols_do): Now static. Accept generic arguments, not
13693 hashing-related ones.
13694
13695 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
13696 (symbol_processor): Remove.
13697 (symbols_do): Remove decl; now static.

13702 (uintptr_t): New type, if system lacks it.
13703 (CALLOC, MALLOC, REALLOC): New macros.
13704 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
13705 new macros.
13706
13707 * src/tables.c (table_size): Now int, to pacify GCC.
13708 (table_grow, table_ninf_remap): Use signed table size.
13709 (save_row): Don't bother initializing locals when not needed.
13710 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
13711 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
13712
13713 * src/vcg.h: Correct misspellings.
13714
13715 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.

13722 Change identifier spellings to avoid collisions with names
13723 that are reserved by POSIX.
13724
13725 Don't use names ending in _t, since POSIX reserves them.
13726 For consistency, remove _e and _s endings -- they're weren't
13727 needed to remove ambiguity. All uses changed.
13728 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
13729 turn was just renamed from struniq_t.
13730 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,

13869 then the ../lib include files in angle brackets (alphabetized),
13870 then the . include files in double-quotes (alphabetized). Fix
13871 dependency breakages encountered in this process, as follows:

13941 instead of returning ID immediately, since we need to search for
13942 a subsequent colon.
13943 (<INITIAL>"'", "\""): Save token_start.

14251 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
14252 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
14253 Group compiler. Instead, use "$CC -E bar.c". Include the .h
14254 file twice in the grammar, as an extra check.
14255
14256 * tests/input.at (Torturing the Scanner): Surround the
14257 backslash-newline tests with "#if 0", to make it less likely that
14258 we'll run into compiler bugs. Bring back solitary \ inside
14259 comment, but add a closing comment to work around HP C bug. Don't
e3aa65c5 14260 test backslash-newline in C character constant.

14502 an escape. Use @oline@ and @ofile@ rather than __oline__ and
14503 __ofile__, to avoid unexpected expansions. Similarly, use @output
14504 rather than #output.
14505
14506 * data/c.m4 (b4_copyright): Omit file name from comment, since
14507 the file name could contain "*/".

15288 Let nondeterministic skeletons be usable with deterministic
15289 tables.
15290
15291 With the patch, GAWK compiled by GCC without -O2 passes its test
15292 suite using a GLR parser driven by LALR tables. It fails with -O2
15293 because `struct stat' gives two different answers on my machine:
15294 88 (definition of an auto var) and later 96 (memset on this var).
15295 Hence the stack is badly corrumpted. The headers inclusion is to

15297 inclusion, the two struct stat have the same size.

15339 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
15340 only value for error actions.

15351 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
15352 because the Bison parser reads the second action before reducing
15353 the first one.
15354 * src/scan-gram.l (rule_length): New static var.
15355 Use it to keep track of the rule length in the scanner, since
15356 we can't expect the parser to be in lock-step sync with the scanner.
15357 (handle_action_dollar, handle_action_at): Use this var.

15460 Do not use "struct bitset_struct" to mean different things in
15461 different modules. Not only is this confusing, it violates
15462 the C Standard, which requires that structure types in different

15481 function is of a different type U. Standard C requires that a
15482 function must be called with a type that is compatible with its
15483 definition.
15484 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):

15866 to void, to avoid a GCC warning when --disable-nls is in effect.
15867

15869 to minimize the number of warnings from xgettext.
15870 (handle_action_dollar, handle_action_at): Don't use isdigit,

15872 outside the C locale.
15873
15874 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
15875 this is a GCC extension and is not portable to other compilers.

15878 Do not include <ctype.h>; no longer needed.

15880 warnings on OpenBSD 3.0).
15881
15882 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
15883 it's not portable.
15884
15885 * tests/regression.at: Do not use 'cc -c input.c -o input';
15886 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
15887
15888 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
15889 exit status as failure, not just exit status 1. Sun C exits
15890 with status 2 sometimes.

18488 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
18489 file will be used.
18490 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.

18492 usable in M4, rename the muscles using `-' to `_'.

19110 Be sure to preserve the value of the eoftoken.
19111 (reader): Make sure eoftoken is defined.

19113 * src/print.c (print_grammar): Don't special case the eof token.
19114 * src/regression.at: Adjust: `$' has value 0, not -1, which was a

19209 the switch/case/break flesh.
19210 Don't parse the user action that might follow the guard, let...
19211 (readgram): do it, i.e., now, there can be an action after a

22390 Test also `--verbose', `--defines' and `--name-prefix'. Testing
22391 the latter demonstrates a flaw in the handling of non debugging
22392 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
22393 was used in order to simplify:
22394
22395 #if YYDEBUG
22396 if (yydebug)
22397 {
22398 ...
22399 }
22400 #endif

22402 into
22403
22404 if (yydebug)
22405 {
22406 ...
22407 }
22408
22409 unfortunately this leads to a CPP conflict when

22411 foodebug'.

22461 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
22462 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
22463 difficult and introduced a lot of core dump. It turns out that
22464 Bison used an implementation of `xmalloc' based on `calloc', and
22465 at various places it does depend upon the initialization to 0. I
22466 have not tried to isolate the pertinent places, and all the former
22467 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
22468 someone should address this issue.

22838 Change the handling of @s so that they behave exactly like $s.
22839 There is now a pseudo variable @$ (readble and writable), location
22840 of the lhs of the rule (by default ranging from the location of
22841 the first symbol of the rhs, to the location of the last symbol,

23605 way to specify the flags -n, -l, and -r. Also added hooks for
