230 portability: fix several issues with M4 subprocess.
231
232 M4's output pipe was not being drained upon fatal errors during
233 scan_skel. As a result, broken-pipe messages from M4 were seen
234 on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
235 failure in the test suite. The problem was that, on platforms
236 where the default disposition for SIGPIPE is ignore instead of
237 terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
238 then reported it. However, there's some sort of race condition,
239 because the new test group occasionally succeeded.
240 Reported by Albert Chin at
241 <http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>.
242
243 There were also problems with the test suite livelocking on
244 Tru64 5.1b. Reported by Didier Godefroy at

246 Switching to create_pipe_bidi suggested by Akim Demaille.
247
248 To attempt to solve both of these problems, switch to gnulib's
249 create_pipe_bidi and register M4 process as a slave. Along the
250 way, clean up file name conflict handling, which was affected by
251 the broken-pipe problem before the switch.

261 of output_file_name_check.

263 would be overwritten, use complain instead of fatal, but replace
264 the output file name with /dev/null. Use the /dev/null solution
265 for the case of two conflicting output files as well because it
266 seems safer in case Bison one day tries to open both files at

444 Fix handling of yychar manipulation in user semantic actions.
445 The problem was that yacc.c didn't always update the yychar
446 translation afterwards. However, other skeletons appear to be
447 fine. glr.c appears to already translate yychar before every
448 use. lalr1.cc does not define yychar and does not document its
449 replacement, yyla, for users. It does provide yyclearin, but
450 that does not manipulate yyla and thus requires no translation
451 update. In lalr1.java, yychar is out of scope during semantic
452 actions.
453 * NEWS (2.5): Document.
454 * data/yacc.c (YYBACKUP): Don't bother translating yychar into
455 yytoken here.
456 (yyparse, yypush_parse): Instead, translate before every use of
457 yytoken, and add comments explaining this approach.
458 * tests/actions.at (Destroying lookahead assigned by semantic
459 action): New test group checking that translation happens before
460 lookahead destructor calls at parser return. Previously,
461 incorrect destructors were called.
462 * tests/conflicts.at (%error-verbose and consistent
463 errors): New test group checking that translation happens at
464 syntax error detection before the associated verbose error
465 message and the associated lookahead destructor calls. While
466 the destructor call is fixed by this patch, the verbose error
467 message is currently incorrect due to another bug (see
468 comments in test group), so this is an expected failure for now.

647 yysyntax_error: avoid duplicate lookahead collection.
648 Except when memory reallocation is required, this change
649 eliminates the need to invoke yysyntax_error twice and thus to
650 repeat the collection of lookaheads. It also prepares for
651 future extensions that will make those repetitions more

898 defined.
899 * data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Fix
900 yytable comments: zero indicates syntax error not default
901 action.
902 * data/glr.c (yyis_pact_ninf): Rename to...

904 (yyisDefaultedState): Update for rename.
905 (yyis_table_ninf): Rename to...
906 (yytable_value_is_error): ... this, and check for value zero
907 besides just YYTABLE_NINF.
908 (yygetLRActions): Check for default value from yypact. It
909 appears that this check is always performed before this function
910 is invoked, and so adding the check here is probably redundant.
911 However, the code may evolve after this subtlety is forgotten.
912 Also, update for rename to yytable_value_is_error. Because that
913 macro now checks for zero, a different but equivalent branch of
914 the if-then-else here is evaluated.
915 (yyreportSyntaxError): Update for rename to

993 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
994 For a \0 and similar escape sequences meaning the null
995 character, report an invalid escape sequence instead of an
996 invalid null character because the latter does not actually
997 appear in the user's input.
998 In all escape sequence complaints, don't escape the initial
999 backslash, and don't quote when the sequence appears at the end
1000 of the complaint line unless there's whitespace that quotearg
1001 won't escape.
1002 Consistently say "invalid" not "unrecognized".
1003 Consistently prefer "empty character literal" over "extra
1004 characters in character literal" warning for invalid escape
1005 sequences; that is, consistently discard those sequences.

2708 symbol names will be encoded in C-string literals, tell quotearg to
2709 escape trigraphs. This used to be the default in gnulib.
2710 * tests/regression.at (Token definitions): Because of the change in
2711 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
2712 escapes trigraphs in symbol names. Thus, yytname no longer has
2713 trigraphs unnecessarily doubly escaped. Update test case output.

3841 * src/lalr.c (state_lookahead_tokens_count): For code readability,
3842 move the check for disabled transitions to an aver since conflict
3843 resolution hasn't happened yet.
3844
3845 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3846 labels a state as inconsistent just because it has error transitions.
3847 The original form of this check appeared in revision 1.1 of lalr.c,
3848 which was committed on 1991-12-21. Now (at least), changing the
3849 consistency label on such a state appears to have no useful effect in
3850 any of the places it is examined, which I enumerate below. The key
3851 point to understanding each item in this enumeration is that a state
3852 with an error transition is labelled consistent in the first place only
3853 if it has no rules, so the check cannot matter for states that have
3854 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3855 to try to identify its conflicts, and a state must have *rules* to have
3856 conflicts. (2) Labelling a state as inconsistent will affect how
3857 action_row sets the default *rule* for the state. (3) Labelling a
3858 state as inconsistent will cause build_relations to add lookback edges
3859 to *rules* in that state.

4499 Instead of having skeletons declare all valid %define variables and
4500 %code qualifiers, provide macros that retrieve the associated values
4501 and build these lists automatically. Thus Bison will now warn when a
4502 variable or qualifier is not used by the skeleton in the current
4503 invocation regardless of whether it might sometimes be used by that
4504 skeleton in other invocations. Also, move all %define value macros to
4505 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
4506 form, which is replaced by %code.
4507 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
4508 (b4_check_user_names): ... this, and change the series of valid name
4509 arguments to a single list argument for names used in the skeleton
4510 similar to the existing list argument for names used in the grammar.
4511 Warn instead of complaining.
4512 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
4513 values and %code code, to format %code code properly, and to build
4514 lists of all %define variables and %code qualifiers used in the
4515 skeleton: b4_skeleton_percent_define_variables and
4516 b4_skeleton_percent_code_qualifiers.
4517 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
4518 Remove, and...
4519 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
4520 the skeleton names lists can finish building first. In place of
4521 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
4522 expect the lists b4_user_percent_define_variables and
4523 b4_user_percent_code_qualifiers.

4525 b4_location_type, b4_filename_type, b4_namespace, and
4526 b4_define_location_comparison, update their names to the
4527 b4_percent_define_ namespace.
4528 * data/glr.c: Don't use b4_check_percent_define_variables and
4529 b4_check_percent_code_qualifiers. Use b4_get_percent_code.

4537 b4_use_push_for_pull_if or m4_wrap code will never execute.
4538 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
4539 Rename to...
4540 (muscle_grow_user_name_list): ... this for consistency with the
4541 terminology used in bison.m4.
4542 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
4543 %define variable names, and rename muscle used_percent_define_variables
4544 to user_percent_define_variables.
4545 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
4546 user_percent_code_qualifiers.
4547 (content): Remove.

4968 Enable push parsers to operate in impure mode. Thus, %push-parser no
4969 longer implies %pure-parser. The point of this change is to move
4970 towards being able to test the push parser code by running the entire
4971 test suite as if %push-parser had been declared.
4972 * data/push.c (yypush_parse): For impure mode, remove the
4973 yypushed_char, yypushed_val, and yypushed_loc arguments.
4974 Instead, declare these as local variables initialized to the global
4975 yychar, yylval, and yylloc.
4976 For the first yypush_parse invocation only, restore the initial values
4977 of these global variables when it's time to read a token since they

5026 initialized (with b4_location_initial_line and
5027 b4_location_initial_column) upon calling yypush_parse. However, that
5028 initialization now overwrites the first token's location;

5234 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
5235 `bison ', use m4_index instead of m4_substr since chopping up a string
5236 containing M4-special characters causes problems here.
5237
5238 Fix a couple of bugs related to special characters in user-specified
5239 file names, and make it easier for skeletons to compute output file
5240 names with the same file name prefix as Bison-computed output file
5241 names.
5242 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
5243 b4_parser_file_name and b4_spec_defines_file instead of
5244 @output_parser_name@ and @output_header_name@, which are now redundant.
5245 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
5246 b4_parser_file_name, b4_spec_defines_file, and the new
5247 @basename(FILENAME@) instead of @output_parser_name@ and
5248 @output_header_name@, which inappropriately escaped the file names as
5249 C string literals.

5251 (compute_output_file_names): Move `free (all_but_ext)' to...

5254 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
5255 exactly what MUSCLE_INSERT_STRING used to do.
5256 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
5257 characters are escaped properly.
5258 * src/output.c (prepare): Define muscle file_name_all_but_ext as
5259 all_but_ext.
5260 For pkgdatadir muscle, maintain previous functionality by using
5261 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
5262 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
5263 digraphs would never be expanded. Hopefully no one has M4-special
5264 characters in his Bison installation path.
5265 * src/scan-skel.l: Don't parse @output_header_name@ and
5266 @output_parser_name@ anymore since they're now redundant.
5267 In @output, use decode_at_digraphs.
5268 Parse a new @basename command that invokes last_component.

5621 Otherwise, checking that a midrule's $$ is set will not always work
5622 properly because the midrule check must forward-reference the midrule's

6134 Whether the default %destructor/%printer applies to a particular symbol
6135 isn't a question of whether the user *declares* that symbol (in %token,
6136 for example). It's a question of whether the user by any means
6137 *defines* the symbol at all (by simply using a char token, for
6138 example). $end is defined by Bison whereas any other token with token
6139 number 0 is defined by the user. The error token is always defined by
6140 Bison regardless of whether the user declares it with %token, but we
6141 may one day let the user define error as a nonterminal instead.

6360 Make the skeletons consistent in how they pop the end token and invoke
6361 its %destructor.
6362 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
6363 state, which has token number 0, since this would invoke the
6364 %destructor for the end token.
6365 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
6366 until after shifting the end token, or else it won't be popped.
6367 * data/yacc.c (yyparse): Likewise.
6368
6369 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
6370 it's the end token. Upon termination, destroy an unshifted lookahead
6371 even when it's the end token.

6387 overwritten by autopoint.
6388 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
6389 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
6390 rejects them.
6391 Don't use autoreconf; instead, invoke autopoint etc. by hand,
6392 so that we can remove the intl files at a better time.
6393 (intl_files_to_remove): Remove aclocal.m4, since it gets
6394 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
6395 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,

6458 YYSTYPE if your grammar contains at least one <type> tag.

6530 this was never guaranteed, and now that we're using gnulib stdint,

6542 no longer copies it.
6543 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
6544 since stdint needs the former and wcwidth (which is now required
6545 by mbswidth) needs the latter.
6546 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
6547 work around a compatibility glitch between gettext 0.14.6 and
6548 Autoconf 2.60.

6660 warnings about types for $$, $n, @$, and @n can't be reported yet.
6661 (packgram): Translate the action and invoke grammar_rule_check now that
6662 all symbol declarations have been parsed.
6663 * src/scan-code.l (handle_action_dollar): Now that this is invoked
6664 after parsing the entire grammar file, the symbol list here in the case
6665 of a midrule is actually the midrule's empty RHS, so reference its
6666 parent rule's RHS where necessary.
6667 On the other hand, now that you can already know it's a midrule, you

6675 terminates a rule. symbol_list_print already does this correctly.
6676 * src/symlist.h (symbol_list.midrule_parent_rule,

7196 state before an empty RHS is always resolved here. Only the location
7197 of that state is guaranteed to be resolved, and that's enough. This

7200 * tests/glr-regression.at (Uninitialized location when reporting

7202 Also, the embedded comments in this test case claim it checks the case
7203 of an empty RHS that has inherited the initial location. However, the
7204 corresponding LHS was already resolved, so yyresolveLocations didn't
7205 actually have reason to modify it. Fix this by forcing
7206 nondeterministic operation at the beginning of the parse.

7625 During deterministic GLR operation, user actions should be able to
7626 influence the parse by changing yychar. To make this easier to fix and

7655 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
7656 got from <http://bro-ids.org/download.html>. The bug is that
7657 when two actions appeared in succession, the second one was
7658 scanned before the first one was added to the grammar rule
7659 as a midrule action. Bison then output the incorrect warning
7660 "parse.y:905.17-906.36: warning: unused value: $3".

7923 In the yychar entry, remove mention of the local yychar case (pure
7924 parser) since this is irrelevant information when writing semantic

7950 Allocate, deallocate, resize, and otherwise shuffle space for
7951 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
7952 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status

7989 * data/glr.c (yyresolveValue): When merging semantic options, if at
7990 least one user action succeeds but a later one cuts the parse, then
7991 destroy the semantic value before returning rather than leaking it.
7992 (yyresolveStates): If a user action cuts the parse and thus
7993 yyresolveValue fails, ignore the (unset) semantic value rather than
7994 corrupting the yyGLRState, and empty the semantic options list since
7995 the user actions should have called all necessary destructors.

8679 Use unlocked I/O for a minor performance improvement on hosts like
8680 GNU/Linux and Solaris that support unlocked I/O. The basic idea
8681 is to use the gnlib unlocked-io module, and to prefer putc and

9130 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
9131 that the byte '\0xff' is not printable in the C locale; it is,
9132 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
9133 not printable, so use '\0x81' to test.

9302 and isn't needed since ./types shouldn't be emitting trailing
9303 spaces.

9388 Fix typos in explanations of the runtime file.
9389 * bootstrap: Change gettext keyword from YYI18N to YY_.
9390 Use standard Makefile.in.in in runtime-po, since we'll arrange
9391 for backward-compatible bison-runtime.po files in a different way.
9392 * data/glr.c (YY_): New macro, from yacc.c.
9393 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
9394 Translate messages intended for users.

10208 not much of an issue.
10209
10210 This change does not affect the generated parsers; that's a different
10211 task, as some users will want to conserve memory there.
10212
10213 Ideally we should use size_t to represent all object counts, and
10214 something like ptrdiff_t to represent signed differences of object
10215 counts; but that will require more code-cleanup than I have the
10216 time to do right now.

10614 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
10615 whether the reducion was empty or not. This leaves room to
10616 improve the use of YYLLOC_DEFAULT in such a case.
10617 lalr1.cc is still experimental, so changing this is acceptable.
10618 And finally, there are probably not many users who changed the
10619 handling of locations in GLR, so changing is admissible too.

10621 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an

10765 Bison directive from the Bison file to the invocation of this

10767 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
10768 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
10769 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10770 the extra Bison directives instead of the whole series.
10771 Change the grammar so that there are recoverable errors, and
10772 unrecoverable errors. Now we can have the parser give up before
10773 consuming the whole input. As a result we now can observe that
10774 the lookahead is freed when needed.
10775 Change the parser source to parse argv[1] instead of a hard coded
10776 string.
10777 Simplify yylex, and give a value and location to EOF.
10778 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10779 passed directives already coded in the file.
10780 Add some tests to check the location of "error".
10781 For some tests, the C++ parser is correct, and not yacc.c.
10782 For other tests, they provide different, but unsatisfying, values,
10783 so keep the C++ value so that at least one parser is "correct"
10784 according to the test suite.
10785 (Actions after errors): Remove, this is subsumed by the
10786 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

10966 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
10967 a seemingly endless set of combinations of versions more recent
10968 than that. The bottom line is that the current sources require
10969 fairly recent versions of the build tools, and it'll be some work
10970 to change this.
10971 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
10972 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
10973 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
10974 Add comments explaining why those particular versions are
10975 currently needed.

11486 When reducing initial empty rules, Bison parser read an initial
11487 location that is not defined. This results in garbage, and that

26ec81e0

11785 The problem was that GLR parsers did not conform to the C standard,
11786 because actions like { $1 = $2 + $3; } expanded to expressions
11787 that invoked YYFILL in separate subexpressions, and YYFILL assigned
11788 to a local variable. The C standard says that expressions
11789 like (var = f ()) + (var = f ()) have undefined behavior.
11790 Another problem was that GCC sometimes issues warnings that
11791 yyfill and its parameters are unused.
11792
11793 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
11794 as possibly unused.
11795 (yyfill): New function.
11796 (YYFILL): Use it.
11797 (yyuserAction): Change type of yynormal to bool, so that it matches
11798 the new yyfill signature. Mark it as possibly unused.

11801 Follow up on a bug I reported in February, where a Bison-generated
11802 parser can loop. Provide a test case and a fix for yacc.c. I
11803 don't have a fix for lalr1.cc or for glr.c, unfortunately.
11804 The original bug report is in:

11806
11807 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
11808 macro's size was becoming unwieldy.
11809 (yyerrlab): Do not discard an empty lookahead symbol, as this
11810 might destroy garbage.
11811 (yyerrorlab): New label, with the old contents of YYERROR,
11812 plus the following change: pop the stack of rhs corresponding
11813 to the production that invoked YYERROR. That is how Yacc
11814 behaves, and POSIX requires this behavior.
11815 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
11816 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
11817 Define 'alarm' to do nothing if unistd.h is not available.
11818 Add a new rule "exp: '-' error;" to test the above change to
11819 data/yacc.c. Use 'alarm' to abort any test taking longer than
11820 10 seconds, as it's probably looping.
11821 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11822 Also, the new yacc.c generates two fewer diagnostics for an
11823 existing test.

12451 we don't need to worry about yyerrlab1 being reported as an
12452 "unused label" by non-GCC C compilers. The downside is that if
12453 locations are used then a couple of statements are duplicated each
12454 time YYERROR is invoked, but the upside is that the warnings
12455 should vanish.
12456 (yyerrlab1): Move code to YERROR.

12472 free the last state, and then use the top state (the one we just
12473 popped). This means that the initial elements will not be freed
12474 explicitly, as is the case in yacc.c; it is not a problem, as
12475 these elements have fake values.

12586 * src/conflicts.c (conflict_report):
12587 Renamed from conflict_report_yacc, removing the old
12588 'conflict_report'. Translate the entire conflict report at once,
12589 so that we don't assume that "," has the same interpretation in
12590 all languages.
12591 (conflicts_output): Use Yacc-style conflict report for each state,
12592 instead of our more-complicated style.
12593 (conflicts_print): Use Yacc-style conflict report, except print
12594 the input file name when not emulating Yacc.

12608 Fix a bug where error locations were not being recorded correctly.
12609 This problem was originally reported by Paul Hilfinger in

12612 * data/yacc.c (yyparse): New local var yylerrsp, to record the
12613 top of the location stack's error locations.
12614 (yyerrlab): Set it. When discarding a token, push its location
12615 onto yylerrsp so that we don't lose track of the error's end.
12616 (yyerrlab1): Now is only the target of YYERROR, so that we can
12617 properly record the location of the action that failed. For GCC
12618 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
12619 GCC warning about yyerrlab1 being unused if YYERROR is unused.
12620 (yyerrlab2): New label, which yyerrlab now falls through to.
12621 Compute the error's location by applying YYLLOC_DEFAULT to
12622 the locations of all the symbols that went into the error.
12623 * doc/bison.texinfo (Location Default Action): Mention that
12624 YYLLOC_DEFAULT is also invoked for syntax errors.
12625 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
12626 Error locations include the locations of all the tokens that were
12627 discarded, not just the last token.

12684 If the user does not define YYSTYPE as a macro, Bison now declares it
12685 using typedef instead of defining it as a macro. POSIX requires this.
12686 For consistency, YYLTYPE is also declared instead of defined.
12687
12688 %union directives can now have a tag before the `{', e.g., the
12689 directive `%union foo {...}' now generates the C code
12690 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
12691 The default union tag is `YYSTYPE', for compatibility with Solaris 9
12692 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
12693 instead of `yyltype'.
12694
12695 `yystype' and `yyltype' are now obsolescent macros instead of being
12696 typedefs or tags; they are no longer documented and will be
12697 withdrawn in a future release.

12702 (struct YYLTYPE): Renamed from struct yyltype.
12703 (YYLTYPE): Renamed from yyltype.
12704 (yyltype, yystype): New (and obsolescent) macros,
12705 for backward compatibility.
12706 * data/yacc.c: Likewise.
12707
12708 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
12709 does not specify a union tag. This is for compatibility with
12710 Solaris 9 yacc.

12731 to return when scanning braced code.

12800
12801 Remove unportable casts and storage allocation tricks.
12802 While we're at it, remove almost all casts, since they
12803 usually aren't needed and are a sign of trouble.
12804
12805 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
12806
12807 * src/derives.c (derives_compute): Do not subtract NTOKENS from
12808 the pointer DSET returned by malloc; this isn't portable.
12809 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
12810 Similarly for DERIVES.
12811 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
12812 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
12813 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
12814
12815 * src/derives.c (derives_compute): Do not bother invoking
12816 int_of_rule_number, since rule numbers are integers.
12817
12818 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
12819 rather than XMALLOC (char, N).
12820
12821 * src/files.c (filename_split): Rewrite to avoid cast.
12822
12823 * src/gram.h (symbol_number_as_item_number,
12824 item_number_as_symbol_number, rule_number_as_item_number,
12825 item_number_as_rule_number):
12826 Now inline functions rather than macros, to avoid casts.
12827 * src/state.h (state_number_as_int): Likewise.
12828 * src/tables.c (state_number_to_vector_number,
12829 symbol_number_to_vector_number): Likewise.
12830
12831 * src/gram.h (int_of_rule_number): Remove; no longer used.
12832
12833 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
12834 since the resulting storage is always stored into.
12835
12836 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
12837 where it's needed.
12838
12839 * src/muscle_tab.c (muscle_m4_output):
12840 Now inline. Return bool, not int.
12841 * src/state.c (state_compare): Likewise.
12842 * src/symtab.c (symbol_check_defined,
12843 symbol_check_alias_consistency, symbol_pack, symbol_translation,
12844 hash_compare_symbol, hash_symbol):
12845 Likewise.
12846 * src/uniqstr.c (uniqstr_print): Likewise.
12847 * src/muscle_tab.c (muscle_m4_output_processor):
12848 New function, to avoid casts.
12849 * src/state.c (state_comparator, stage_hasher): Likewise.
12850 * src/symtab.c (symbol_check_defined_processor,
12851 symbol_check_alias_consistency_processor, symbol_pack_processor,
12852 symbol_translation_processor, hash_symbol_comparator,
12853 hash_symbol_hasher): Likewise.
12854 * src/uniqstr.c (uniqstr_print_processor): Likewise.
12855 * src/muscle_tab.c (muscles_m4_output):
12856 Use new functions instead of casting old functions unportably.
12857 * src/state.c (state_hash_new): Likewise.
12858 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
12859 symbols_token_translations_init):
12860 Likewise.
12861 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
12862
12863 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
12864 var instead of casting to long, to avoid casts.
12865 (prepare_states): Use MALLOC rather than alloca, so that we don't
12866 have to worry about alloca.
12867 * src/state.c (state_hash_lookup): Likewise.
12868
12869 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
12870 local var instead of casting to unsigned char, to avoid casts.
12871
12872 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
12873 STATE_ALLOC): Remove.
12874 (transitions_new, errs_new, reductions_new, state_new): Use malloc
12875 rather than calloc, and use offsetof to avoid allocating slightly
12876 too much storage.
12877 (state_new): Initialize all members.
12878
12879 * src/state.c (state_hash): Use unsigned accumulator, not signed.
12880
12881 * src/symtab.c (symbol_free): Remove; unused.
12882 (symbol_get): Remove cast in lhs of assignment.
12883 (symbols_do): Now static. Accept generic arguments, not
12884 hashing-related ones.
12885
12886 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
12887 (symbol_processor): Remove.
12888 (symbols_do): Remove decl; now static.

12891 (<stddef.h>): Include, for offsetof.
12892 (<inttypes.>, <stdint.h>): Include if available.
12893 (uintptr_t): New type, if system lacks it.
12894 (CALLOC, MALLOC, REALLOC): New macros.
12895 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
12896 new macros.
12897
12898 * src/tables.c (table_size): Now int, to pacify GCC.
12899 (table_grow, table_ninf_remap): Use signed table size.
12900 (save_row): Don't bother initializing locals when not needed.
12901 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
12902 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
12903
12904 * src/vcg.h: Correct misspellings.
12905
12906 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
12907
12908

12913 Change identifier spellings to avoid collisions with names
12914 that are reserved by POSIX.
12915
12916 Don't use names ending in _t, since POSIX reserves them.
12917 For consistency, remove _e and _s endings -- they're weren't
12918 needed to remove ambiguity. All uses changed.
12919 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
12920 turn was just renamed from struniq_t.

13690 Use new @ escapes consistently. Represent brackets with @{ and @}
13691 rather than @<:@ and @:>@, since this works a bit better with dumb

13693 an escape. Use @oline@ and @ofile@ rather than __oline__ and
13694 __ofile__, to avoid unexpected expansions. Similarly, use @output
13695 rather than #output.
13696
13697 * data/c.m4 (b4_copyright): Omit file name from comment, since
13698 the file name could contain "*/".

14102 The last OS that we could find where this wouldn't work is
14103 SunOS 3.5, and that's too old to worry about now.
14104
14105 * data/glr.c (struct yyltype): Define members even when not

14479 Let nondeterministic skeletons be usable with deterministic
14480 tables.
14481
14482 With the patch, GAWK compiled by GCC without -O2 passes its test
14483 suite using a GLR parser driven by LALR tables. It fails with -O2
14484 because `struct stat' gives two different answers on my machine:
14485 88 (definition of an auto var) and later 96 (memset on this var).
14486 Hence the stack is badly corrumpted. The headers inclusion is to

14488 inclusion, the two struct stat have the same size.

14599 Portability fixes for bitsets; this also avoids several GCC
14600 warnings.
14601
14602 * lib/abitset.c: Include <stddef.h>, for offsetof.
14603 * lib/lbitset.c: Likewise.
14604
14605 * lib/abitset.c (abitset_bytes): Return a size that is aligned
14606 properly for vectors of objects. Do not assume that adding a
14607 header size to a multiple of a word size yields a value that is
14608 properly aligned for the whole union.
14609 * lib/bitsetv.c (bitsetv_alloc): Likewise.
14610
14611 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
14612 unique names for structures.
14613 * lib/ebitset.c (ebitset_bytes): Likewise.
14614 * lib/lbitset.c (lbitset_bytes): Likewise.
14615
14616 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
14617 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
14618 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
14619 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
14620 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
14621 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
14622 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
14623 to improve the type-checking that GCC can do.
14624 * lib/bitset.c (bitset_op4_cmp): Likewise.
14625 * lib/bitset_stats.c (bitset_stats_count,
14626 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
14627 bitset_stats_copy, bitset_stats_disjoint_p,

14633 bitset_stats_andn_or_cmp, bitset_stats_or_and,
14634 bitset_stats_or_and_cmp): Likewise.
14635 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
14636 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
14637 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
14638 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
14639
14640 * lib/abitset.h: Include bitset.h, not bbitset.h.
14641 * lib/ebitset.h: Likewise.
14642 * lib/lbitset.h: Likewise.
14643
14644 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
14645 All instances of parameters of type enum bitset_opts are now of
14646 type enum_bitset_opts, to conform to the C Standard, and similarly
14647 for enum_bitset_type.
14648 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
14649 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
14650
14651 Do not use "struct bitset_struct" to mean different things in
14652 different modules. Not only is this confusing, it violates
14653 the C Standard, which requires that structure types in different
14654 modules must be compatible if one is to be passed to the other.
14655 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
14656 All instances of "struct bitset_struct *" replaced with "bitset".
14657 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
14658 (union bitset_union, struct abitset_struct, struct ebitset_struct,
14659 struct lbitset_struct, struct bitset_stats_struct): New types.
14660 All uses of struct bitset_struct changed to union bitset_union,
14661 etc.
ba0fe3c7 14662 * lib/abitset.c (struct abitset_struct, abitset,
f28a0f2d
PE
14663 struct bitset_struct): Remove.
14664 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
14665 struct bitset_struct): Remove.
14666 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
14667 bitset_struct): Remove.
14668 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
14669 Likewise.
14670
14671 Do not call a function of type T using a call that assumes the
14672 function is of a different type U. Standard C requires that a
14673 function must be called with a type that is compatible with its
14674 definition.
14675 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
14676 New decls.
14677 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
14678 New functions.
14679 * lib/ebitset.c (PFV): Remove.
14680 * lib/lbitset.c (PFV): Likewise.
14681 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
14682 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
14683 decls.
14684 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
14685 (ebitset_vtable): Use them.
14686 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
14687 lbitset_xor): New functions.
14688 (lbitset_vtable): Use them.
14689
14690 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
14691 Declare.
14692
14693 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
14694 GCC warning.
14695 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
14696 Use offsetof, for simplicity.

14701 the same width as int. This reapplies a hunk of the 2002-08-12 patch

14714 fixes.
14715 (Symbols): Mention that any negative value returned from yylex
14716 signifies end-of-input. Warn about negative chars. Mention
14717 the portable Standard C character set.
14718
14719 The GNU coding standard says CFLAGS and YFLAGS are reserved
14720 for the installer to set.
14721 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
14722 * src/Makefile.am (AM_CFLAGS): Likewise.
14723 (AM_YFLAGS): Renamed from YFLAGS.
14724
14725 Fix some MAX and MIN problems.

14728 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
14729 * src/reader.c (reader): Use it.
14730
14731 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
14732 POSIX 1003.1-2001 has removed fgrep.
14733
147342002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>

15080 exit status as failure, not just exit status 1. Sun C exits
15081 with status 2 sometimes.

17026 (state_t.number): Is a token_number_t.

17028 hard coded 2.
17029 (Even though this 2 is not the same as above: the number of the
17030 undeftoken remains being 2, it is its user token number which
17031 might not be 2).

17076 passes, but produces negative #line number, once fixed, GCC is
17077 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of

17673 line number, hence remove the second argument.

17675 action member.
17676 Adjust callers.
17677 (output_skeleton): Don't look for the skeleton location, let m4 do
17678 that.
17679 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
17680 file will be used.
17681 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
17682 (prepare): Given that for the time being changesyntax is not
17683 usable in M4, rename the muscles using `-' to `_'.
17684 Define `defines_flag', `output_parser_name' and `output_header_name'.
17685 * src/output.h (actions_output, guards_output)
17686 (token_definitions_output): Adjust prototypes.

17688 processes the output of m4: `__oline__' and `#output'.

18301 Be sure to preserve the value of the eoftoken.
18302 (reader): Make sure eoftoken is defined.

18304 * src/print.c (print_grammar): Don't special case the eof token.
18305 * src/regression.at: Adjust: `$' has value 0, not -1, which was a

18858 When looking if the start_symbol is shifted from the initial

18860 better than `while (... symbol < start_symbol ...)': If fail
18861 to see how the order between symbols could be relevant!

21545 The location tracking mechanism is precious for parse error
21546 messages. Nevertheless, it is enabled only when `@n' is used in
21547 the grammar, which is a different issue (you can use it in error

21549 be another means to enable it.

21581 Test also `--verbose', `--defines' and `--name-prefix'. Testing
21582 the latter demonstrates a flaw in the handling of non debugging
21583 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
21584 was used in order to simplify:
21585
21586 #if YYDEBUG

21595 if (yydebug)
21596 {
21597 ...
21598 }
21599

21652 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
21653 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
21654 difficult and introduced a lot of core dump. It turns out that
21655 Bison used an implementation of `xmalloc' based on `calloc', and
21656 at various places it does depend upon the initialization to 0. I
21657 have not tried to isolate the pertinent places, and all the former
21658 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
21659 someone should address this issue.

22790 (lex): Implemented "..." tokens.
22791 (literalchar, lex, parse_percent_token): Made tokenbuffer
22792 always contain the token. This includes growing the token
22793 buffer while reading an integer.
22794 (parse_percent_token): Replaced if-else statement with percent_table.
22795 (parse_percent_token): Added % declarations as another
22796 way to specify the flags -n, -l, and -r. Also added hooks for
22797 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
22798 major changes to files.c.
22799 (lex) Retain in the incoming stream a character following
22800 an incorrect '/'.
