82 Fix complaints about escape sequences.
83 Discussed starting at
84 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>.
85 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
86 For a \0 and similar escape sequences meaning the null
87 character, report an invalid escape sequence instead of an
88 invalid null character because the latter does not actually
89 appear in the user's input.
90 In all escape sequence complaints, don't escape the initial
91 backslash, and don't quote when the sequence appears at the end
92 of the complaint line unless there's whitespace that quotearg
93 won't escape.
94 Consistently say "invalid" not "unrecognized".
95 * tests/input.at (Bad escapes in literals): New.

116 build: lower gettext requirements.

118 Bison was uselessly requiring the formatstring macros from
119 gettext, which resulted in mo files not being installed on systems

210 the Flex manual, but which Flex has supported since at least as
211 far back as 2.5.4. However, if any of our developers still use
212 Flex 2.5.4, they'll need to stop configuring with

2206 * src/lalr.c (state_lookahead_tokens_count): For code readability,
2207 move the check for disabled transitions to an aver since conflict
2208 resolution hasn't happened yet.
2209
2210 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
2211 labels a state as inconsistent just because it has error transitions.
2212 The original form of this check appeared in revision 1.1 of lalr.c,
2213 which was committed on 1991-12-21. Now (at least), changing the
2214 consistency label on such a state appears to have no useful effect in
2215 any of the places it is examined, which I enumerate below. The key
2216 point to understanding each item in this enumeration is that a state
2217 with an error transition is labelled consistent in the first place only
2218 if it has no rules, so the check cannot matter for states that have
2219 rules. (1) Labelling a state as inconsistent will cause set_conflicts
2220 to try to identify its conflicts, and a state must have *rules* to have
2221 conflicts. (2) Labelling a state as inconsistent will affect how
2222 action_row sets the default *rule* for the state. (3) Labelling a
2223 state as inconsistent will cause build_relations to add lookback edges
2224 to *rules* in that state.

2864 Instead of having skeletons declare all valid %define variables and
2865 %code qualifiers, provide macros that retrieve the associated values
2866 and build these lists automatically. Thus Bison will now warn when a
2867 variable or qualifier is not used by the skeleton in the current
2868 invocation regardless of whether it might sometimes be used by that
2869 skeleton in other invocations. Also, move all %define value macros to
2870 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
2871 form, which is replaced by %code.

2876 Warn instead of complaining.
2877 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define

3333 Enable push parsers to operate in impure mode. Thus, %push-parser no
3334 longer implies %pure-parser. The point of this change is to move
3335 towards being able to test the push parser code by running the entire
3336 test suite as if %push-parser had been declared.
3337 * data/push.c (yypush_parse): For impure mode, remove the
3338 yypushed_char, yypushed_val, and yypushed_loc arguments.
3339 Instead, declare these as local variables initialized to the global
3340 yychar, yylval, and yylloc.
3341 For the first yypush_parse invocation only, restore the initial values
3342 of these global variables when it's time to read a token since they

3346 * tests/calc.at (Simple LALR(1) Calculator): Always declare

3391 initialized (with b4_location_initial_line and
3392 b4_location_initial_column) upon calling yypush_parse. However, that
3393 initialization now overwrites the first token's location;
3394 %initial-action assigning @$ already did the same thing, and both bugs

3599 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
3600 `bison ', use m4_index instead of m4_substr since chopping up a string
3601 containing M4-special characters causes problems here.
3602
3603 Fix a couple of bugs related to special characters in user-specified
3604 file names, and make it easier for skeletons to compute output file
3605 names with the same file name prefix as Bison-computed output file
3606 names.
3607 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
3608 b4_parser_file_name and b4_spec_defines_file instead of
3609 @output_parser_name@ and @output_header_name@, which are now redundant.
3610 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
3611 b4_parser_file_name, b4_spec_defines_file, and the new
3612 @basename(FILENAME@) instead of @output_parser_name@ and
3613 @output_header_name@, which inappropriately escaped the file names as
3614 C string literals.
3615 * src/files.c (all_but_ext): Remove static qualifier.
3616 (compute_output_file_names): Move `free (all_but_ext)' to...

3619 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
3620 exactly what MUSCLE_INSERT_STRING used to do.
3621 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
3622 characters are escaped properly.
3623 * src/output.c (prepare): Define muscle file_name_all_but_ext as
3624 all_but_ext.
3625 For pkgdatadir muscle, maintain previous functionality by using
3626 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
3627 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
3628 digraphs would never be expanded. Hopefully no one has M4-special
3629 characters in his Bison installation path.
3630 * src/scan-skel.l: Don't parse @output_header_name@ and
3631 @output_parser_name@ anymore since they're now redundant.
3632 In @output, use decode_at_digraphs.
3633 Parse a new @basename command that invokes last_component.

3986 Otherwise, checking that a midrule's $$ is set will not always work
3987 properly because the midrule check must forward-reference the midrule's

4332 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
4333
4334 * src/parse-gram.y (symbol_declaration): Don't put statements
4335 before declarations; it's not portable to C89.
4336 * src/scan-code.l (handle_action_at): Likewise.
4337
4338 * src/scan-code.l: Always initialize braces_level; the old code
4339 left it uninitialized and therefore had undefined behavior.
4340
4341 Don't attempt to redefine 'assert', since it runs afoul of
4342 systems where standard headers (mistakenly) include <assert.h>.
4343 Instead, define and use our own alternative, called 'aver'.
4344 * src/reader.c: Don't include assert.h, since we no longer
4345 use assert.
4346 * src/scan-code.l: Likewise.
4347 * src/system.h (assert): Remove, replacing with....
4348 (aver): New function, taking a bool arg. All uses changed.
4349 * src/tables.c (pack_vector): Ensure that aver arg is bool,
4350 not merely an integer.

4358 * src/getargs.h (push_parser): New declaration.
4359 * src/output.c (prepare): Add macro insertion of `push_flag'.
4360 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
4361 (prologue_declaration): Parse %push-parser.
4362 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
4363 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
4364 list of removed lines from the traces observed.
4365 (AT_CHECK_CALC_LALR): Added push parser tests.

4377 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
4378 runtime cost when YYDEBUG is not defined, and so that some tests
4379 that used to fail now work. Problem and initial suggestion by
4380 Paolo Bonzini.
4381 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.

4383 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.

4390 if YYYDEBUG.
4391 (debug_stream, set_debug_stream, debug_level, set_debug_level):

4402 We don't need them in glr.cc, and glr.c defines them.
4403 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c

4496 Whether the default %destructor/%printer applies to a particular symbol
4497 isn't a question of whether the user *declares* that symbol (in %token,
4498 for example). It's a question of whether the user by any means
4499 *defines* the symbol at all (by simply using a char token, for
4500 example). $end is defined by Bison whereas any other token with token
4501 number 0 is defined by the user. The error token is always defined by
4502 Bison regardless of whether the user declares it with %token, but we
4503 may one day let the user define error as a nonterminal instead.
4504 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
4505 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
4506 the meaning of "user-defined".
4507 * tests/actions.at (Default %printer and %destructor for user-declared
4508 end token): Rename to...
4509 (Default %printer and %destructor for user-defined end token): ...
4510 this.
4511
4512 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
4513 computation of whether to apply the default, don't maintain a list of
4514 every Bison-defined symbol. Instead, just check for a first character
4515 of '$', which a user symbol cannot have, and check for the error token.

4543 Redo some of the previous commit: add back the ability to use
4544 non-aliased/undeclared string literals since it might be useful to
4545 those declaring %token-table.

4547 commit: don't worry about complaints from symbols_pack.
4548 * src/symtab.c (symbol_new, symbol_class_set,
4549 symbol_check_alias_consistency): Undo changes in previous commit: count
4550 each string literal as a new symbol and token, assign it a symbol
4551 number, and don't complain about non-aliased string literals.
4552 (symbols_pack): Since symbol_make_alias still does not decrement symbol
4553 and token counts but does still set aliased tokens to the same number,
4554 symbol_pack_processor now leaves empty slots in the symbols array.

4569 * src/symtab.c (symbol_new): Don't count a string literal as a new
4570 symbol.
4571 (symbol_class_set): Don't count a string literal as a new token, and
4572 don't assign it a symbol number since symbol_make_alias does that.
4573 (symbol_make_alias): It's not necessary to decrement the symbol and
4574 token counts anymore. Don't assume that an alias declaration occurs
4575 before any uses of the identifier or string, and thus don't assert that
4576 one of them has the highest symbol number so far.

4578 that wasn't declared as an alias.

4716 Clean up handling of %destructor for the end token (token 0).
4717 Discussed starting at
4718 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
4719 and
4720 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
4721
4722 Make the skeletons consistent in how they pop the end token and invoke
4723 its %destructor.
4724 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
4725 state, which has token number 0, since this would invoke the
4726 %destructor for the end token.
4727 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
4728 until after shifting the end token, or else it won't be popped.
4729 * data/yacc.c (yyparse): Likewise.
4730
4731 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
4732 it's the end token. Upon termination, destroy an unshifted lookahead
4733 even when it's the end token.
4734 * data/lalr1.cc (yy::parser::parse): Likewise.
4735 * data/yacc.c (yyparse): Likewise.
4736
4737 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
4738 value warnings for the end token when the user gives the end token a
4739 %destructor.
4740
4741 * tests/actions.at (Printers and Destructors): Test all the above.

4745 Update to latest gnulib and gettext versions.
4746 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
4747 Add fopen-safer.
4748 (gnulib_files): Add m4/warning.m4. Don't worry about files
4749 overwritten by autopoint.
4750 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
4751 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
4752 rejects them.
4753 Don't use autoreconf; instead, invoke autopoint etc. by hand,
4754 so that we can remove the intl files at a better time.
4755 (intl_files_to_remove): Remove aclocal.m4, since it gets
4756 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
4757 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
4758 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
4759 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
4760 Remove datarootdir hack; no longer needed.
4761 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
4762 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
4763 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
4764 strdup.h.
4765 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
4766 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.

4820 YYSTYPE if your grammar contains at least one <type> tag.

4891 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
4892 this was never guaranteed, and now that we're using gnulib stdint,
4893 which defines int_fast16_t to long int, the problem is exposed.

4903 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
4904 no longer copies it.
4905 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
4906 since stdint needs the former and wcwidth (which is now required
4907 by mbswidth) needs the latter.
4908 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
4909 work around a compatibility glitch between gettext 0.14.6 and
4910 Autoconf 2.60.

4924 for ../lib/*.h files.
4925 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):

4928 (BASE_QPUTS): Use last_component, not base_name.
4929 * src/system.h: Include <unlocked-io.h> in the usual order
4930 for ../lib/*.h files. Include <stdint.h> unconditionally,
4931 since we now use the stdint module.
4932 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
4933 HAVE_UINTPTR_T, since we now use the stdint module.
4934 (base_name): Remove decl, since files now include <dirname.h>
4935 to get the decl.

5016 Don't record whether the midrule's $$ has been used yet since actions
5017 haven't been translated yet.
5018 Record the midrule's parent rule and its RHS index within the parent
5019 rule.
5020 (grammar_current_rule_action_append): Don't translate the action yet
5021 since not all symbol declarations may have been parsed yet and, thus,
5022 warnings about types for $$, $n, @$, and @n can't be reported yet.
5023 (packgram): Translate the action and invoke grammar_rule_check now that
5024 all symbol declarations have been parsed.
5025 * src/scan-code.l (handle_action_dollar): Now that this is invoked
5026 after parsing the entire grammar file, the symbol list here in the case
5027 of a midrule is actually the midrule's empty RHS, so reference its
5028 parent rule's RHS where necessary.
5029 On the other hand, now that you can already know it's a midrule, you
5030 aren't forced to think $$ has the same type as its parent rule's $$.

5032 where necessary.
5033 * src/symlist.c (symbol_list_new): Initialize new midrule-related
5034 members.
5035 (symbol_list_length): Now that this is invoked after all rules have
5036 been parsed, a NULL symbol (rather than a NULL symbol list node)
5037 terminates a rule. symbol_list_print already does this correctly.
5038 * src/symlist.h (symbol_list.midrule_parent_rule,

5490 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.

5493 * src/.cvsignore: Add revision.c.
5494 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
5495 (BUILT_SOURCES): Add revision.c.
5496 (revision.c): New target rule. This file defines a new global variable
5497 named revision. It initializes it with either the Id from ChangeLog
5498 or, if VERSION doesn't contain `+', with the empty string.
5499 * src/getargs.c (version): Print the value of revision.

5539 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
5540 shell, not within 'make', so that 'make' by an ordinary builder
5541 (using GNU make) does not worry about configuring gzip. This also
5542 works around a bug reported independently by Keith Thompson and by
5543 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
5544 stderr rather than stdout, messing up the build logs.

5550 maintainer-check' failure caused by the recent changes to the 'Trivial
5551 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
5552 not used.

5557 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
5558 state before an empty RHS is always resolved here. Only the location
5559 of that state is guaranteed to be resolved, and that's enough. This
5560 fixes the remaining bug reported by Derek M. Jones in
5561 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5562 * tests/glr-regression.at (Uninitialized location when reporting
5563 ambiguity): Test the above case.
5564 Also, the embedded comments in this test case claim it checks the case
5565 of an empty RHS that has inherited the initial location. However, the
5566 corresponding LHS was already resolved, so yyresolveLocations didn't
5567 actually have reason to modify it. Fix this by forcing
5568 nondeterministic operation at the beginning of the parse.

5575 of the bugs reported today by Derek M Jones in
5576 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.

5578 defined to be a type name without parens or brackets.
5579 (Location Type): Similarly for YYLTYPE.
5580 * tests/regression.at (Trivial grammars): Put in a test for this

6019 when two actions appeared in succession, the second one was
6020 scanned before the first one was added to the grammar rule
6021 as a midrule action. Bison then output the incorrect warning

6278 * doc/bison.texinfo: Fix some typos.
6279 (GLR Semantic Actions): New subsection discussing special
6280 considerations because GLR semantic actions might be deferred.
6281 (Actions): Mention look-ahead usage of yylval.
6282 (Actions and Locations): Mention look-ahead usage of yylloc.
6283 (Special Features for Use in Actions): Add YYEOF entry and mention it
6284 in the yychar entry.
6285 In the yychar entry, remove mention of the local yychar case (pure
6286 parser) since this is irrelevant information when writing semantic
148d66d8 6287 actions and since it's already discussed in `Table of Symbols' where
32c29292
JD
6288 yychar is otherwise described as an external variable.
6289 In the yychar entry, don't call it the `current' look-ahead since it
6290 isn't when semantic actions are deferred.
6291 In the yychar and yyclearin entries, add note about deferred semantic
6292 actions.
6293 Add yylloc and yylval entries discussing look-ahead usage.
6294 (Look-Ahead Tokens): When discussing yychar, don't call it the
6295 `current' look-ahead, and do mention yylval and yylloc.
6296 (Error Recovery): Cross-reference `Action Features' when mentioning
6297 yyclearin.

6308 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
6309 use during nondeterministic operation to track which stacks have
6310 actually needed the current lookahead.
6311 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
6312 Allocate, deallocate, resize, and otherwise shuffle space for
6313 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
6314 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
6315 appropriately during nondeterministic operation.
6316 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
6317 members to store the current lookahead to be used by the deferred
6318 user action.
6319 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
6320 from which the RHS is taken. Set the lookahead members of the new
6321 yySemanticOption according to the lookahead status for stack yyk.
6322 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
6323 yyaddDeferredAction.
6324 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
6325 members of yySemanticOption before invoking yyuserAction, and then set
6326 them back to their current values afterward.
6327 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
6328 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
6329 * tests/glr-regression.at: Remove `.' from the ends of recent test case
6330 titles for consistency.
6331 (Leaked merged semantic value if user action cuts parse): In order to
6332 suppress lint warnings, use arguments in merge function, and assign
6333 char value < 128 in main.

6351 * data/glr.c (yyresolveValue): When merging semantic options, if at
6352 least one user action succeeds but a later one cuts the parse, then
6353 destroy the semantic value before returning rather than leaking it.
6354 (yyresolveStates): If a user action cuts the parse and thus
6355 yyresolveValue fails, ignore the (unset) semantic value rather than
6356 corrupting the yyGLRState, and empty the semantic options list since
6357 the user actions should have called all necessary destructors.
6358 Simplify code with YYCHK.
6359 * tests/glr-regression.at (Corrupted semantic options if user action
6360 cuts parse): New test case.
6361 (Undesirable destructors if user action cuts parse): New test case.
6362 Before applying any of this patch, this test case never actually failed
6363 for me... but only because the corrupted semantic options usually
6364 masked this bug.

7043 is to use the gnlib unlocked-io module, and to prefer putc and
7044 puts to printf when either will work (since the latter doesn't
7045 come in an unlocked flavor).

7465 as the one reported at the end of

7491 uses 'echo', and 'echo' isn't portable if its argument contains
7492 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
7493 that the byte '\0xff' is not printable in the C locale; it is,
7494 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
7495 not printable, so use '\0x81' to test.

7552 it's error-prone and "make maintainer-distcheck" rejects it.

7576 (output_skeleton):
7577 Indent calls to "error" to pacify "make maintainer-distcheck".
7578 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.

7593 "make maintainer-distcheck" complained about.

7606 autogenerated by the maintainer.
7607 * examples/calc++/.cvsignore: Add *.yy.

7624 removed once the bison-runtime domain has been translated by each
7625 team.

7651 * doc/bison.texinfo (Decl Summary, Calling Convention):
7652 Clarify quoting convention of yytname.
7653 * src/output.c (prepare_symbols): Quote all names. This undoes
7654 the 2005-04-17 change, which is now accomplished (mostly) via
7655 changes in the parsers as described above.
7656 * tests/regression.at (Token definitions, Web2c Actions):
7657 Undo most 2005-04-17 change here, too.

7660
7661 Fix more problems reported by twlevo@xs4all.nl.
7662 * tests/cxx-type.at: Don't pipe output of ./types through sed to
7663 remove trailing spaces. This loses the exit status of ./types,
7664 and isn't needed since ./types shouldn't be emitting trailing
7665 spaces.
7666 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
7667 as the stack isn't valid in that case.

7673 is used.

7680 overly-picky compilers that reject 'char *foo = "bar";'.
7681
7682 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
7683 to FILE * parameter, not to stderr. This fixes a typo introduced
7684 in the 2005-07-12 change.
7685
7686 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
7687 warnings from GCC 4.

7702 * data/lalr1.cc (yyerrlab): Likewise.
7703 * data/glr.c (yyparse): Pop everything off the stack before
7704 freeing it, so that destructors get called properly.

7711 Some English-language cleanups for %destructor.
7712 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

7724 Rename yyoverflowab to yyexhaustedlab.
7725 When memory exhaustion occurs during syntax-error reporting,
7726 report it separately rather than in a single diagnostic; this
7727 eases translation.

7738 can be understood only by someone who can read the
7739 (English-language) source code.
7740
7741 Generate runtime-po/bison-runtime.pot automatically, so that we
7742 don't have to worry about garbage getting in that file. We'll
7743 make sure after the next official release that old msgids don't

7748 Now auto-generated.
7749 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
7750 Fix typos in explanations of the runtime file.
7751 * bootstrap: Change gettext keyword from YYI18N to YY_.
7752 Use standard Makefile.in.in in runtime-po, since we'll arrange
7753 for backward-compatible bison-runtime.po files in a different way.
7754 * data/glr.c (YY_): New macro, from yacc.c.
7755 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
7756 Translate messages intended for users.
7757 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
7758 the wording in the other skeletons. We don't know that the memory
7759 is virtual.
7760 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
7761 Use same method that yacc.c uses.
7762 Don't translate debugging messages.
7763 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
7764 it doesn't work (yet), and requires C++ expertise to fix.
7765 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
7766 Move defn to a more logical place, to be consistent with other
7767 skeletons.
7768 Don't translate debugging messages.
7769 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
7770 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
7771 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
7772 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

7788 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
7789 (yyparse): New local variable yyresult to record the result.

7795 if YYABORT is used).

8568 Remove uses of 'short int' and 'unsigned short int'. This raises
8569 some arbitrary limits. It uses more memory but nowadays that's
8570 not much of an issue.
8571
8572 This change does not affect the generated parsers; that's a different
8573 task, as some users will want to conserve memory there.
8574
8575 Ideally we should use size_t to represent all object counts, and
8576 something like ptrdiff_t to represent signed differences of object
8577 counts; but that will require more code-cleanup than I have the

8976 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
8977 whether the reducion was empty or not. This leaves room to
8978 improve the use of YYLLOC_DEFAULT in such a case.
8979 lalr1.cc is still experimental, so changing this is acceptable.
8980 And finally, there are probably not many users who changed the
8981 handling of locations in GLR, so changing is admissible too.
8982
8983 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
8984 empty reduction, set @$ to an empty location ending the previously
8985 stacked symbol.
8986 Adjust uses to make sure the code is triggered on empty
8987 reductions.
8988 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
8989 expected output: empty reductions have empty locations.

9126 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
9127 Bison directive from the Bison file to the invocation of this
9128 macro, so that these directives are passed to
9129 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
9130 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
9131 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
9132 the extra Bison directives instead of the whole series.
9133 Change the grammar so that there are recoverable errors, and
9134 unrecoverable errors. Now we can have the parser give up before
9135 consuming the whole input. As a result we now can observe that
9136 the lookahead is freed when needed.
9137 Change the parser source to parse argv[1] instead of a hard coded
9138 string.
9139 Simplify yylex, and give a value and location to EOF.
9140 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
9141 passed directives already coded in the file.
9142 Add some tests to check the location of "error".
9143 For some tests, the C++ parser is correct, and not yacc.c.
9144 For other tests, they provide different, but unsatisfying, values,
9145 so keep the C++ value so that at least one parser is "correct"
9146 according to the test suite.
9147 (Actions after errors): Remove, this is subsumed by the
9148 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

9326 Spent a few hours checking out which prerequisite versions the
9327 current sources actually require. I went all the way back to
9328 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
9329 a seemingly endless set of combinations of versions more recent
9330 than that. The bottom line is that the current sources require
9331 fairly recent versions of the build tools, and it'll be some work
9332 to change this.

9372 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
9373 autopoint's.

9601 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
9602 unused declaration.
9603

9848 When reducing initial empty rules, Bison parser read an initial
9849 location that is not defined. This results in garbage, and that
9850 affects Bison's own parser. Therefore we need (i) to extend Bison

10147 The problem was that GLR parsers did not conform to the C standard,
10148 because actions like { $1 = $2 + $3; } expanded to expressions
10149 that invoked YYFILL in separate subexpressions, and YYFILL assigned
10150 to a local variable. The C standard says that expressions
10151 like (var = f ()) + (var = f ()) have undefined behavior.
10152 Another problem was that GCC sometimes issues warnings that
10153 yyfill and its parameters are unused.
10154
10155 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
10156 as possibly unused.
10157 (yyfill): New function.
10158 (YYFILL): Use it.
10159 (yyuserAction): Change type of yynormal to bool, so that it matches
10160 the new yyfill signature. Mark it as possibly unused.

10163 Follow up on a bug I reported in February, where a Bison-generated
10164 parser can loop. Provide a test case and a fix for yacc.c. I
10165 don't have a fix for lalr1.cc or for glr.c, unfortunately.
10166 The original bug report is in:

10169 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
10170 macro's size was becoming unwieldy.
10171 (yyerrlab): Do not discard an empty lookahead symbol, as this
10172 might destroy garbage.
10173 (yyerrorlab): New label, with the old contents of YYERROR,
10174 plus the following change: pop the stack of rhs corresponding
10175 to the production that invoked YYERROR. That is how Yacc
10176 behaves, and POSIX requires this behavior.
10177 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10178 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10179 Define 'alarm' to do nothing if unistd.h is not available.
10180 Add a new rule "exp: '-' error;" to test the above change to
10181 data/yacc.c. Use 'alarm' to abort any test taking longer than
10182 10 seconds, as it's probably looping.
10183 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
10184 Also, the new yacc.c generates two fewer diagnostics for an
10185 existing test.

10813 we don't need to worry about yyerrlab1 being reported as an
10814 "unused label" by non-GCC C compilers. The downside is that if
10815 locations are used then a couple of statements are duplicated each
10816 time YYERROR is invoked, but the upside is that the warnings
10817 should vanish.
10818 (yyerrlab1): Move code to YERROR.
10819 (yyerrlab2): Remove. Change uses back to yyerrlab1.
10820 This reverts some of the 2002-12-27 change.

10835 popped). This means that the initial elements will not be freed
10836 explicitly, as is the case in yacc.c; it is not a problem, as
10837 these elements have fake values.

10949 Renamed from conflict_report_yacc, removing the old
10950 'conflict_report'. Translate the entire conflict report at once,
10951 so that we don't assume that "," has the same interpretation in

10953 (conflicts_output): Use Yacc-style conflict report for each state,
10954 instead of our more-complicated style.

10971 This problem was originally reported by Paul Hilfinger in

10974 * data/yacc.c (yyparse): New local var yylerrsp, to record the
10975 top of the location stack's error locations.
10976 (yyerrlab): Set it. When discarding a token, push its location
10977 onto yylerrsp so that we don't lose track of the error's end.
10978 (yyerrlab1): Now is only the target of YYERROR, so that we can
10979 properly record the location of the action that failed. For GCC
10980 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
10981 GCC warning about yyerrlab1 being unused if YYERROR is unused.
10982 (yyerrlab2): New label, which yyerrlab now falls through to.
10983 Compute the error's location by applying YYLLOC_DEFAULT to
10984 the locations of all the symbols that went into the error.
10985 * doc/bison.texinfo (Location Default Action): Mention that
10986 YYLLOC_DEFAULT is also invoked for syntax errors.
10987 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

11046 If the user does not define YYSTYPE as a macro, Bison now declares it
11047 using typedef instead of defining it as a macro. POSIX requires this.
11048 For consistency, YYLTYPE is also declared instead of defined.
11049
11050 %union directives can now have a tag before the `{', e.g., the
11051 directive `%union foo {...}' now generates the C code
11052 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
11053 The default union tag is `YYSTYPE', for compatibility with Solaris 9
11054 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
11055 instead of `yyltype'.
11056
11057 `yystype' and `yyltype' are now obsolescent macros instead of being
11058 typedefs or tags; they are no longer documented and will be
11059 withdrawn in a future release.

11067 for backward compatibility.
11068 * data/yacc.c: Likewise.
11069

11071 does not specify a union tag. This is for compatibility with
11072 Solaris 9 yacc.

11093 to return when scanning braced code.

11423 then the . include files in double-quotes (alphabetized). Fix

12052 Use new @ escapes consistently. Represent brackets with @{ and @}
12053 rather than @<:@ and @:>@, since this works a bit better with dumb
12054 editors like vi. Represent @ with @@, since @ is now consistently
12055 an escape. Use @oline@ and @ofile@ rather than __oline__ and
12056 __ofile__, to avoid unexpected expansions. Similarly, use @output
12057 rather than #output.
12058
12059 * data/c.m4 (b4_copyright): Omit file name from comment, since
12060 the file name could contain "*/".

12103 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
12104 Use new escapes @{ and @} for [ and ].
12105
12106 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
12107 them with auto vars.
12108 Switch to new escape scheme, where @ is the escape character uniformly.
12109 Abort if a stray escape character is found. Avoid unbounded input
12110 buffer when parsing non-escaped text.
12111

12122 (yygetLRActions, yyrecoverParseError): Use them.

12124 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
12125 counted in the token inserted at end of file. Now takes
12126 location_t *, not location_t, so that the location can be
12127 adjusted. All uses changed.

12349 as well as \000. Check for UCHAR_MAX, not 255.

12351 Check for overflow here.
12352 Allow \? and UCNs, for compatibility with C.

12394 returned zero.
12395 * src/files.c (xfclose): Likewise. Report I/O error if ferror
12396 indicates one.
12397 * src/output.c (output_skeleton): Use xfclose rather than fclose

12464 The last OS that we could find where this wouldn't work is
12465 SunOS 3.5, and that's too old to worry about now.
12466
12467 * data/glr.c (struct yyltype): Define members even when not
12468 doing locations. This is more consistent with yacc.c, and it

12483 Be consistent about 'bool'; the old code used an enum in one
12484 module and an int in another, and this violates the C standard.

12486 * configure.ac (AC_HEADER_STDBOOL): Add.
12487 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.

12841 Let nondeterministic skeletons be usable with deterministic
12842 tables.
12843
12844 With the patch, GAWK compiled by GCC without -O2 passes its test
12845 suite using a GLR parser driven by LALR tables. It fails with -O2
12846 because `struct stat' gives two different answers on my machine:
12847 88 (definition of an auto var) and later 96 (memset on this var).
12848 Hence the stack is badly corrumpted. The headers inclusion is to
12849 blame: if I move the awk.h inclusion before GLR's system header
12850 inclusion, the two struct stat have the same size.

15390 hard coded 2.
15391 (Even though this 2 is not the same as above: the number of the
15392 undeftoken remains being 2, it is its user token number which
15393 might not be 2).

16318 in warnings for `unused: yy_flex_realloc'.

16511 * tests/regression.at (Web2c Actions): Blindly move the actual
16512 output as expected output. The contents *seem* right to me, but I
16513 can't pretend reading perfectly parser tables... Nonetheless, all
16514 the other tests pass correctly, the table look OK, even though the
16515 presence of `$axiom' is to be noted: AFAICS it is useless (but
16516 harmless).

16608 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
16609 twice `Now at end of input', therefore there are two lines less to
16610 expect.

16623 (insert_accepting_state, augment_automaton): Remove, since now
16624 these states are automatically computed from the initial state.
16625 (generate_states): Adjust.
16626 * src/print.c: When reporting a rule number to the user, substract
16627 1, so that the axiom rule is rule 0, and the first user rule is 1.
16628 * src/reduce.c: Likewise.
16629 * src/print_graph.c (print_core): For the time being, just as for
16630 the report, depend upon --trace-flags to dump the full set of
16631 items.
16632 * src/reader.c (readgram): Once the grammar read, insert the rule
16633 0: `$axiom: START-SYMBOL $'.
16634 * tests/set.at: Adjust: rule 0 is now displayed, and since the
16635 number of the states has changed (the final state is no longer
16636 necessarily the last), catch up.

16640 Try to make the use of the eoftoken valid. Given that its value
16641 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
16642 is used instead of > 0 where appropriate, (ii), depend upon nritems
16643 instead of the 0-sentinel.

16657 reductions, then output the report anyway if requested, then die.

16659 * src/reader.c (eoftoken): New.
16660 (parse_token_decl): If the token being defined has value `0', it
16661 is the eoftoken.
16662 (packsymbols): No longer hack `tags' to insert `$' by hand.
16663 Be sure to preserve the value of the eoftoken.
16664 (reader): Make sure eoftoken is defined.
16665 Initialize nsyms to 0: now eoftoken is created just like the others.
16666 * src/print.c (print_grammar): Don't special case the eof token.
16667 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
16668 lie anyway, albeit pleasant.
16669 * tests/calc.at: Exercise error messages with eoftoken.
16670 Change the grammar so that empty input is invalid.

16763 Don't parse the user action that might follow the guard, let...

17098 * src/print_graph.c (print_core): Complete the set of items via
17099 closure. The next-to-final and final states are still unsatisfying,
17100 but that's to be addressed elsewhere.
17101 No longer output the rule numbers, but do output the state number.
17102 A single loop for the shifts + gotos is enough, but picked a

17511 Because useless nonterminals are now kept alive (instead of being

17521 `shift_symbol', containing the symbol that can be shifted from a
17522 given state.
17523 Deobfuscate, i.e., allocate, use and free `symbol_count' here
17524 only, and...

18107 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
18108 now the tests are run in private dirs, therefore AC_CLEANUP and
18109 family can be simplified to 0-ary.
18110 * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
18111 use abs. path to find config.h.
18112 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

18137 arg is const.

19907 The location tracking mechanism is precious for parse error
19908 messages. Nevertheless, it is enabled only when `@n' is used in

19911 be another means to enable it.

19943 Test also `--verbose', `--defines' and `--name-prefix'. Testing
19944 the latter demonstrates a flaw in the handling of non debugging
19945 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
19946 was used in order to simplify:
19947
19948 #if YYDEBUG
19949 if (yydebug)
19950 {

19957 if (yydebug)
19958 {
19959 ...
19960 }
19961

20014 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
20015 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
20016 difficult and introduced a lot of core dump. It turns out that
20017 Bison used an implementation of `xmalloc' based on `calloc', and
20018 at various places it does depend upon the initialization to 0. I
20019 have not tried to isolate the pertinent places, and all the former
20020 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

21108 (parse_token_decl): Extended the %token
21109 declaration to allow a multi-character symbol as an alias.
21110 (parse_thong_decl): New function.

21121 Revised and use multiple warnxxx functions to avoid using VARARGS1.
21122 (read_declarations): Improve the error message for
21123 an invalid character. Do not abort.
21124 (read_declarations, copy_guard, copy_action): Use
21125 printable_version to avoid unprintable characters in printed output.
21126 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.

21148 Include getopt.h. Add some extern decls.
21149 (safegetc): New function to deal with EOF gracefully.
21150 (literalchar); new function to deal with reading \ escapes.
21151 (lex): Use literalchar.
21152 (lex): Implemented "..." tokens.
21153 (literalchar, lex, parse_percent_token): Made tokenbuffer
21154 always contain the token. This includes growing the token
21155 buffer while reading an integer.
21156 (parse_percent_token): Replaced if-else statement with percent_table.
21157 (parse_percent_token): Added % declarations as another
21158 way to specify the flags -n, -l, and -r. Also added hooks for
21159 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
21160 major changes to files.c.
21161 (lex) Retain in the incoming stream a character following
21162 an incorrect '/'.
21163 (skip_white_space, lex): Revised most error messages
21164 and changed fatal to warn to avoid aborting.
