35 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
36 that's now the caller's responsibility.

63 Automatically generated dependencies are important even
64 when all of the sources in a directory come from gnulib.
65 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
66 option that gnulib-tool adds to what becomes our lib/gnulib.mk.

104 to copies-of-gnulib.
105 (cp_mark_as_generated, slurp, gnulib_files):

122 (XGETTEXT_OPTIONS): Add complain, complain_at,
123 fatal, fatal_at, warn, warn_at, unexpected_end.
124 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
125 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
126 (gl_EARLY): Add.
127 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
128 (gl_INIT): Add
129 (GNULIB_AUTOCONF_SNIPPET): Remove.
130 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
131 the pickiest.
132 * lib/.cvsignore: Add inttypes_.h.
133 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
134 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
135 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
136 no-longer-necessary initializations.
137 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
138 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
139 use the unistd module.

141 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,

143 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
144 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
145 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
146 * src/system.h: Include inttypes.h unconditionally, now that we
147 use the inttypes module. Don't bother to include stdint.h, since
148 inttypes.h now does that for us.
149 (LOCALEDIR): Remove, now that we use the configmake module.
150 * src/getargs.c: Include configmake.h.
151 * src/main.c: Likewise.
152 * src/output.c: Likewise.

157 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
158 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
159
160 * src/parse-gram.y (symbol_declaration): Don't put statements
161 before declarations; it's not portable to C89.
162 * src/scan-code.l (handle_action_at): Likewise.
163
164 * src/scan-code.l: Always initialize braces_level; the old code
165 left it uninitialized and therefore had undefined behavior.
166
167 Don't attempt to redefine 'assert', since it runs afoul of
168 systems where standard headers (mistakenly) include <assert.h>.
169 Instead, define and use our own alternative, called 'aver'.
170 * src/reader.c: Don't include assert.h, since we no longer
171 use assert.
172 * src/scan-code.l: Likewise.
173 * src/system.h (assert): Remove, replacing with....
174 (aver): New function, taking a bool arg. All uses changed.
175 * src/tables.c (pack_vector): Ensure that aver arg is bool,
176 not merely an integer.

183 * src/getargs.c (push_parser): New var.

187 (prologue_declaration): Parse %push-parser.
188 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.

201 was there.

203 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
204 runtime cost when YYDEBUG is not defined, and so that some tests
205 that used to fail now work. Problem and initial suggestion by
206 Paolo Bonzini.
207 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
208 * data/glr.cc (b4_parser_class_name):
209 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
210 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
211 (yydebug_) [YYDEBUG]: New member.
212 (yycdebug_): Now defined only if YYDEBUG.
213 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
214 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
215 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
216 if YYYDEBUG.
217 (debug_stream, set_debug_stream, debug_level, set_debug_level):
218 Define only if YYDEBUG.
219 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
220 set_debug_level.
221 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.

228 We don't need them in glr.cc, and glr.c defines them.
229 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
230 assumes that defining it to anything is the same as defining
231 it to 1. Problem reported by Paolo Bonzini.

241 * data/glr.c (b4_shared_declarations): Put start-header first,
242 before any #includes that we generate, so that feature-test
243 macros work. Problem reported by Michael Deutschmann in
244 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
245 * data/lalr1.cc: Likewise.
246 * doc/bison.texinfo (Prologue): Document that feature-test macros
247 should be defined before any Bison declarations.
248 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
249 that depend on location.hh after, not before, Bison decls, since
250 we now include location.hh after the first user prologue.
251

252 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
253 Sander Brandenburg in

255 Also, fix minor white space and comment issues.

260 by Jim Meyering.

275 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
276 list node contains a semantic type.
277 * src/symtab.c, src/symtab.h: Extend with a table that associates
278 semantic types with their %destructor's and %printer's.
279 (semantic_type_from_uniqstr, semantic_type_get,
280 semantic_type_destructor_set, semantic_type_printer_set): New functions
281 composing the public interface of that table.
282 (symbol_destructor_get, symbol_destructor_location_get,
283 symbol_printer_get, symbol_printer_location_get): If there's no
284 per-symbol %destructor/%printer, look up the per-type before trying
285 the default.
286 * tests/actions.at (Per-type %printer and %destructor): New test case.
287 * tests/input.at (Default %printer and %destructor redeclared):
288 Extend to check that multiple occurrences of %symbol-default in a
289 single %destructor/%printer declaration is an error.

301 (Bison Symbols): Add entry for %symbol-default.
302 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
303 (generic_symlist, generic_symlist_item): New nonterminals for creating
304 a list in which each item is a symbol, semantic type, or
305 %symbol-default.
306 (grammar_declaration): Use generic_symlist in %destructor and %printer
307 declarations instead of symbols.1 or an empty list.
308 (symbol_declaration, precedence_declaration, symbols.1): Update actions
309 for changes to symbol_list.

313 * src/symlist.c, src/symlist.h: Extend such that a list node may
314 represent a semantic type or a %symbol-default in addition to just an
315 ordinary symbol. Add switched functions for setting %destructor's and
316 %printer's.
317 * tests/actions.at, tests/input.at: Add %symbol-default to all default

322 Whether the default %destructor/%printer applies to a particular symbol
323 isn't a question of whether the user *declares* that symbol (in %token,
324 for example). It's a question of whether the user by any means
325 *defines* the symbol at all (by simply using a char token, for
326 example). $end is defined by Bison whereas any other token with token
327 number 0 is defined by the user. The error token is always defined by
328 Bison regardless of whether the user declares it with %token, but we
329 may one day let the user define error as a nonterminal instead.
330 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
331 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
332 the meaning of "user-defined".
333 * tests/actions.at (Default %printer and %destructor for user-declared
334 end token): Rename to...
335 (Default %printer and %destructor for user-defined end token): ...
336 this.
337
338 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
339 computation of whether to apply the default, don't maintain a list of
340 every Bison-defined symbol. Instead, just check for a first character
341 of '$', which a user symbol cannot have, and check for the error token.

345 Don't apply the default %destructor or %printer to the error token,
346 $undefined, or $accept. This change fits the general rule that the
347 default %destructor and %printer are only for user-declared symbols,
348 and it solves several difficulties that are described in the new test
349 cases listed below.
350 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.

361 declarations have been parsed. Skip midrules, which have dummy LHS
362 nonterminals.

369 Redo some of the previous commit: add back the ability to use
370 non-aliased/undeclared string literals since it might be useful to
371 those declaring %token-table.
372 * src/reader.c (check_and_convert_grammar): Undo changes in previous
373 commit: don't worry about complaints from symbols_pack.
374 * src/symtab.c (symbol_new, symbol_class_set,
375 symbol_check_alias_consistency): Undo changes in previous commit: count
376 each string literal as a new symbol and token, assign it a symbol
377 number, and don't complain about non-aliased string literals.
378 (symbols_pack): Since symbol_make_alias still does not decrement symbol
379 and token counts but does still set aliased tokens to the same number,
380 symbol_pack_processor now leaves empty slots in the symbols array.
381 Remove those slots.
382 * tests/regression.at (Undeclared string literal): Remove test case
383 added in previous commit since non-aliased string literals are allowed
384 again.

394 symbols_pack complained.
395 * src/symtab.c (symbol_new): Don't count a string literal as a new
396 symbol.
397 (symbol_class_set): Don't count a string literal as a new token, and
398 don't assign it a symbol number since symbol_make_alias does that.
399 (symbol_make_alias): It's not necessary to decrement the symbol and
400 token counts anymore. Don't assume that an alias declaration occurs
401 before any uses of the identifier or string, and thus don't assert that
402 one of them has the highest symbol number so far.
403 (symbol_check_alias_consistency): Complain if there's a string literal
404 that wasn't declared as an alias.
405 (symbols_pack): Bail if symbol_check_alias_consistency failed since
406 symbol_pack asserts that every token has been assigned a symbol number
407 although undeclared string literals have not.

838 * src/reader.c (grammar_current_rule_end): Don't invoke
839 grammar_rule_check yet since not all symbol declarations may have been

842 Don't record whether the midrule's $$ has been used yet since actions
843 haven't been translated yet.
844 Record the midrule's parent rule and its RHS index within the parent
845 rule.
846 (grammar_current_rule_action_append): Don't translate the action yet
847 since not all symbol declarations may have been parsed yet and, thus,
848 warnings about types for $$, $n, @$, and @n can't be reported yet.
849 (packgram): Translate the action and invoke grammar_rule_check now that
850 all symbol declarations have been parsed.
851 * src/scan-code.l (handle_action_dollar): Now that this is invoked
852 after parsing the entire grammar file, the symbol list here in the case
853 of a midrule is actually the midrule's empty RHS, so reference its
854 parent rule's RHS where necessary.
855 On the other hand, now that you can already know it's a midrule, you
856 aren't forced to think $$ has the same type as its parent rule's $$.
857 (handle_action_at): In the case of a midrule, reference the parent rule
858 where necessary.
859 * src/symlist.c (symbol_list_new): Initialize new midrule-related
860 members.
861 (symbol_list_length): Now that this is invoked after all rules have
862 been parsed, a NULL symbol (rather than a NULL symbol list node)
863 terminates a rule. symbol_list_print already does this correctly.
864 * src/symlist.h (symbol_list.midrule_parent_rule,
865 symbol_list.midrule_parent_rhs_index): New members so that midrules can
866 remember their relationships with their parents.
867 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
868 fixed by the above patch.
869 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
870 implementing...
871 (Unused values): ... this old test case and...
872 (Unused values before symbol declarations): ... this new test case.
873 This one is the same as `Unused values' except that all symbol
874 declarations appear after the rules in order to catch the rest of the

1394 actually have reason to modify it. Fix this by forcing

2868 Use unlocked I/O for a minor performance improvement on hosts like
2869 GNU/Linux and Solaris that support unlocked I/O. The basic idea

3320 that the byte '\0xff' is not printable in the C locale; it is,
3321 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are

3491 and isn't needed since ./types shouldn't be emitting trailing
3492 spaces.

3554 eases translation.

3562 Add i18n support to the GLR skeleton. Partially fix the C++
3563 skeleton; a C++ expert needs to finish this. Remove debugging
3564 msgids; there's little point to having them translated, since they
3565 can be understood only by someone who can read the
3566 (English-language) source code.
3567
3568 Generate runtime-po/bison-runtime.pot automatically, so that we
3569 don't have to worry about garbage getting in that file. We'll
3570 make sure after the next official release that old msgids don't
3571 get lost. See
3572 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.

3577 Fix typos in explanations of the runtime file.
3578 * bootstrap: Change gettext keyword from YYI18N to YY_.
3579 Use standard Makefile.in.in in runtime-po, since we'll arrange
3580 for backward-compatible bison-runtime.po files in a different way.
3581 * data/glr.c (YY_): New macro, from yacc.c.

3583 Translate messages intended for users.
3584 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
3585 the wording in the other skeletons. We don't know that the memory
3586 is virtual.

3588 Use same method that yacc.c uses.
3589 Don't translate debugging messages.
3590 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
3591 it doesn't work (yet), and requires C++ expertise to fix.

3593 Move defn to a more logical place, to be consistent with other
3594 skeletons.
3595 Don't translate debugging messages.
3596 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
3597 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
3598 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.

3947 Various maintainer cleanups.
3948 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
3949 conftest*, for benefit of CVS commands run at the same time as
3950 "configure". Add build-aux, since "bootstrap" now creates it and
3951 its subfiles.
3952 * Makefile.cfg (move_if_change): Remove.
3953 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
3954 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
3955 (po_repo, do-po-update, po-update, wget_files, get-targets):
3956 (config.guess-url_prefix, config.sub-url_prefix):
3957 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
3958 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
3959 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
3960 Remove.
3961 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
3962 this is now the recommended name.
3963 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
3964 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
3965 ylwrap. These files now go into build-aux.

3969 * bootstrap: Add stdio-safer, unistd-safer modules.
3970 Remove m4/glibc2.m4 (introduced by latest gnulib, but
3971 we don't need it).
3972 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
3973 fopen-safer.c, stdio-safer.h, unistd-safer.h.
3974 * lib/subpipe.c: Include "unistd-safer.h".
3975 (create_subpipe): Make sure all the newly-created
3976 file descriptors are > 2, so that diagnostics don't
3977 get sent down them (which might cause Bison to hang, in theory).
3978 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
3979 * src/files.c (xfopen): Use fopen_safer, not fopen.

4322 * NEWS: Bison-generated parsers no longer default to using the
4323 alloca function (when available) to extend the parser stack, due
4324 to widespread problems in unchecked stack-overflow detection.
4325 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's

4327 specify a value that is not a preprocessor constant.

4395 Remove uses of 'short int' and 'unsigned short int'. This raises
4396 some arbitrary limits. It uses more memory but nowadays that's
4397 not much of an issue.
4398
4399 This change does not affect the generated parsers; that's a different
4400 task, as some users will want to conserve memory there.

4402 Ideally we should use size_t to represent all object counts, and

4803 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
4804 whether the reducion was empty or not. This leaves room to
4805 improve the use of YYLLOC_DEFAULT in such a case.
4806 lalr1.cc is still experimental, so changing this is acceptable.
4807 And finally, there are probably not many users who changed the
4808 handling of locations in GLR, so changing is admissible too.

4954 Bison directive from the Bison file to the invocation of this
4955 macro, so that these directives are passed to
4956 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
4957 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
4958 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
4959 the extra Bison directives instead of the whole series.
4960 Change the grammar so that there are recoverable errors, and
4961 unrecoverable errors. Now we can have the parser give up before
4962 consuming the whole input. As a result we now can observe that
4963 the lookahead is freed when needed.
4964 Change the parser source to parse argv[1] instead of a hard coded
4965 string.
4966 Simplify yylex, and give a value and location to EOF.
4967 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
4968 passed directives already coded in the file.
4969 Add some tests to check the location of "error".
4970 For some tests, the C++ parser is correct, and not yacc.c.
4971 For other tests, they provide different, but unsatisfying, values,
4972 so keep the C++ value so that at least one parser is "correct"
4973 according to the test suite.
4974 (Actions after errors): Remove, this is subsumed by the
4975 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

5153 Spent a few hours checking out which prerequisite versions the
5154 current sources actually require. I went all the way back to
5155 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
5156 a seemingly endless set of combinations of versions more recent
5157 than that. The bottom line is that the current sources require
5158 fairly recent versions of the build tools, and it'll be some work
5159 to change this.
5160 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
5161 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
5162 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.

5972 Fix a GLR parser bug I reported in February; see

5974 The problem was that GLR parsers did not conform to the C standard,
5975 because actions like { $1 = $2 + $3; } expanded to expressions
5976 that invoked YYFILL in separate subexpressions, and YYFILL assigned
5977 to a local variable. The C standard says that expressions
5978 like (var = f ()) + (var = f ()) have undefined behavior.
5979 Another problem was that GCC sometimes issues warnings that
5980 yyfill and its parameters are unused.
5981
5982 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
5983 as possibly unused.
5984 (yyfill): New function.
5985 (YYFILL): Use it.
5986 (yyuserAction): Change type of yynormal to bool, so that it matches
5987 the new yyfill signature. Mark it as possibly unused.
5988
5989
5990 Follow up on a bug I reported in February, where a Bison-generated
5991 parser can loop. Provide a test case and a fix for yacc.c. I
5992 don't have a fix for lalr1.cc or for glr.c, unfortunately.
5993 The original bug report is in:

5995
5996 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
5997 macro's size was becoming unwieldy.
5998 (yyerrlab): Do not discard an empty lookahead symbol, as this
5999 might destroy garbage.
6000 (yyerrorlab): New label, with the old contents of YYERROR,
6001 plus the following change: pop the stack of rhs corresponding
6002 to the production that invoked YYERROR. That is how Yacc
6003 behaves, and POSIX requires this behavior.
6004 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
6005 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
6006 Define 'alarm' to do nothing if unistd.h is not available.
6007 Add a new rule "exp: '-' error;" to test the above change to
6008 data/yacc.c. Use 'alarm' to abort any test taking longer than
6009 10 seconds, as it's probably looping.
6010 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
6011 Also, the new yacc.c generates two fewer diagnostics for an
6012 existing test.

6640 we don't need to worry about yyerrlab1 being reported as an
6641 "unused label" by non-GCC C compilers. The downside is that if
6642 locations are used then a couple of statements are duplicated each
6643 time YYERROR is invoked, but the upside is that the warnings
6644 should vanish.

6660 when the stacks contain one element, as the loop would otherwise
6661 free the last state, and then use the top state (the one we just
6662 popped). This means that the initial elements will not be freed
6663 explicitly, as is the case in yacc.c; it is not a problem, as
6664 these elements have fake values.

6773 * doc/bison.texinfo (Understanding): Use Yacc style for

6775 * src/conflicts.c (conflict_report):
6776 Renamed from conflict_report_yacc, removing the old
6777 'conflict_report'. Translate the entire conflict report at once,
6778 so that we don't assume that "," has the same interpretation in
6779 all languages.
6780 (conflicts_output): Use Yacc-style conflict report for each state,
6781 instead of our more-complicated style.
6782 (conflicts_print): Use Yacc-style conflict report, except print
6783 the input file name when not emulating Yacc.
6784 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
6785 Conflicted Reduction, %expect not enough, %expect too much,

6801 * data/yacc.c (yyparse): New local var yylerrsp, to record the
6802 top of the location stack's error locations.
6803 (yyerrlab): Set it. When discarding a token, push its location
6804 onto yylerrsp so that we don't lose track of the error's end.
6805 (yyerrlab1): Now is only the target of YYERROR, so that we can
6806 properly record the location of the action that failed. For GCC
6807 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
6808 GCC warning about yyerrlab1 being unused if YYERROR is unused.
6809 (yyerrlab2): New label, which yyerrlab now falls through to.
6810 Compute the error's location by applying YYLLOC_DEFAULT to
6811 the locations of all the symbols that went into the error.
6812 * doc/bison.texinfo (Location Default Action): Mention that
6813 YYLLOC_DEFAULT is also invoked for syntax errors.
6814 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

6816 discarded, not just the last token.

6873 If the user does not define YYSTYPE as a macro, Bison now declares it
6874 using typedef instead of defining it as a macro. POSIX requires this.
6875 For consistency, YYLTYPE is also declared instead of defined.
6876
6877 %union directives can now have a tag before the `{', e.g., the
6878 directive `%union foo {...}' now generates the C code
6879 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
6880 The default union tag is `YYSTYPE', for compatibility with Solaris 9
6881 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
6882 instead of `yyltype'.
6883
6884 `yystype' and `yyltype' are now obsolescent macros instead of being
6885 typedefs or tags; they are no longer documented and will be
6886 withdrawn in a future release.

6892 (YYLTYPE): Renamed from yyltype.
6893 (yyltype, yystype): New (and obsolescent) macros,
6894 for backward compatibility.
6895 * data/yacc.c: Likewise.
6896

6898 does not specify a union tag. This is for compatibility with
6899 Solaris 9 yacc.

6918 has (or usually has) an immediately-following braced code.

6920 to return when scanning braced code.

6989
6990 Remove unportable casts and storage allocation tricks.
6991 While we're at it, remove almost all casts, since they
6992 usually aren't needed and are a sign of trouble.
6993
6994 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
6995
6996 * src/derives.c (derives_compute): Do not subtract NTOKENS from
6997 the pointer DSET returned by malloc; this isn't portable.
6998 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
6999 Similarly for DERIVES.
7000 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
7001 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
7002 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
7003
7004 * src/derives.c (derives_compute): Do not bother invoking
7005 int_of_rule_number, since rule numbers are integers.
7006
7007 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
7008 rather than XMALLOC (char, N).
7009
7010 * src/files.c (filename_split): Rewrite to avoid cast.
7011
7012 * src/gram.h (symbol_number_as_item_number,
7013 item_number_as_symbol_number, rule_number_as_item_number,
7014 item_number_as_rule_number):
7015 Now inline functions rather than macros, to avoid casts.
7016 * src/state.h (state_number_as_int): Likewise.
7017 * src/tables.c (state_number_to_vector_number,
7018 symbol_number_to_vector_number): Likewise.
7019
7020 * src/gram.h (int_of_rule_number): Remove; no longer used.
7021
7022 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
7023 since the resulting storage is always stored into.
7024
7025 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
7026 where it's needed.
7027
7028 * src/muscle_tab.c (muscle_m4_output):
7029 Now inline. Return bool, not int.
7030 * src/state.c (state_compare): Likewise.

7038 * src/state.c (state_comparator, stage_hasher): Likewise.
7039 * src/symtab.c (symbol_check_defined_processor,
7040 symbol_check_alias_consistency_processor, symbol_pack_processor,
7041 symbol_translation_processor, hash_symbol_comparator,
7042 hash_symbol_hasher): Likewise.
7043 * src/uniqstr.c (uniqstr_print_processor): Likewise.
7044 * src/muscle_tab.c (muscles_m4_output):
7045 Use new functions instead of casting old functions unportably.
7046 * src/state.c (state_hash_new): Likewise.
7047 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
7048 symbols_token_translations_init):
7049 Likewise.
7050 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
7051
7052 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
7053 var instead of casting to long, to avoid casts.
7054 (prepare_states): Use MALLOC rather than alloca, so that we don't
7055 have to worry about alloca.
7056 * src/state.c (state_hash_lookup): Likewise.
7057
7058 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
7059 local var instead of casting to unsigned char, to avoid casts.
7060

7062 STATE_ALLOC): Remove.
7063 (transitions_new, errs_new, reductions_new, state_new): Use malloc
7064 rather than calloc, and use offsetof to avoid allocating slightly
7065 too much storage.
7066 (state_new): Initialize all members.
7067
7068 * src/state.c (state_hash): Use unsigned accumulator, not signed.
7069
7070 * src/symtab.c (symbol_free): Remove; unused.
7071 (symbol_get): Remove cast in lhs of assignment.
7072 (symbols_do): Now static. Accept generic arguments, not
7073 hashing-related ones.
7074
7075 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
7076 (symbol_processor): Remove.
7077 (symbols_do): Remove decl; now static.
7078
7079 * src/system.h (alloca): Remove; decl no longer needed.

7081 (<inttypes.>, <stdint.h>): Include if available.
7082 (uintptr_t): New type, if system lacks it.
7083 (CALLOC, MALLOC, REALLOC): New macros.
7084 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
7085 new macros.
7086
7087 * src/tables.c (table_size): Now int, to pacify GCC.
7088 (table_grow, table_ninf_remap): Use signed table size.

7093 * src/vcg.h: Correct misspellings.
7094
7095 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
7096
7097
7098 * src/getargs.c (getargs): Don't assume EOF == -1.

7101
7102 Change identifier spellings to avoid collisions with names
7103 that are reserved by POSIX.
7104
7105 Don't use names ending in _t, since POSIX reserves them.
7106 For consistency, remove _e and _s endings -- they're weren't
7107 needed to remove ambiguity. All uses changed.

7109 turn was just renamed from struniq_t.

7249 then the ../lib include files in angle brackets (alphabetized),
7250 then the . include files in double-quotes (alphabetized). Fix
7251 dependency breakages encountered in this process, as follows:
7252 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".

7319 processing of Yacc white space and equivalents here.
7320 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
7321 instead of returning ID immediately, since we need to search for
7322 a subsequent colon.
7323 (<INITIAL>"'", "\""): Save token_start.
7324 (<INITIAL>"%{", "{", "%%"): Save code_start.
7325 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.

7879 Use new @ escapes consistently. Represent brackets with @{ and @}
7880 rather than @<:@ and @:>@, since this works a bit better with dumb
7881 editors like vi. Represent @ with @@, since @ is now consistently
7882 an escape. Use @oline@ and @ofile@ rather than __oline__ and
7883 __ofile__, to avoid unexpected expansions. Similarly, use @output
7884 rather than #output.
7885
7886 * data/c.m4 (b4_copyright): Omit file name from comment, since
7887 the file name could contain "*/".
7888 (b4_synclines_flag): Don't quote the 2nd argument; it should already
7889 be quoted. All uses changed.

7903 mishandled funny characters in file names, and anyway it isn't
7904 needed any more.
7905 * data/yacc.c: Likewise.
7906 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.

7927 escapes other than \\ and \'; this simplifies the code.

7929 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
7930 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
7931 Use new escapes @{ and @} for [ and ].
7932
7933 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
7934 them with auto vars.
7935 Switch to new escape scheme, where @ is the escape character uniformly.
7936 Abort if a stray escape character is found. Avoid unbounded input
7937 buffer when parsing non-escaped text.

7948 table.
7949 (yygetLRActions, yyrecoverParseError): Use them.
7950
7951 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
7952 counted in the token inserted at end of file. Now takes
7953 location_t *, not location_t, so that the location can be
7954 adjusted. All uses changed.

8178 Check for overflow here.
8179 Allow \? and UCNs, for compatibility with C.

8182 with quote slot used by complain_at.
8183
8184 * tests/input.at: Add tests for backslash-newline, m4 quotes
8185 in symbols, long literals, and funny escapes in strings.

8211 escape "[" as "@<:@" and likewise for "]".

8223 indicates one.
8224 * src/output.c (output_skeleton): Use xfclose rather than fclose

8248 we use malloc. Don't assume 'A' through 'Z' are contiguous.

8289 decl; not needed any more.
8290 * src/main.c (main): Use return to exit, undoing yesterday's change.
8291 The last OS that we could find where this wouldn't work is
8292 SunOS 3.5, and that's too old to worry about now.
8293
8294 * data/glr.c (struct yyltype): Define members even when not
8295 doing locations. This is more consistent with yacc.c, and it
8296 works around the following bug reports:

8310 Be consistent about 'bool'; the old code used an enum in one

8312 * m4/stdbool.m4: New file, from coreutils 4.5.3.
8313 * configure.ac (AC_HEADER_STDBOOL): Add.
8314 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.

8337 What was that "2" for?
8338
8339 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
8340 * src/getargs.c (usage): Likewise.
8341
8342 * src/getargs.c (getargs): When there are too few operands, report
8343 the last one. When there are too many, report the first extra
8344 one. This is how diffutils does it.

8354 * src/complain.h: Assume prototypes.
8355 * src/system.h (PARAMS): Remove.
8356 Include <limits.h> unconditionally, since it's guaranteeed even
8357 for a freestanding C89 compiler.

8534 it confused me, and I was the author! Instead, assume that people

8668 Let nondeterministic skeletons be usable with deterministic
8669 tables.
8670
8671 With the patch, GAWK compiled by GCC without -O2 passes its test
8672 suite using a GLR parser driven by LALR tables. It fails with -O2
8673 because `struct stat' gives two different answers on my machine:
8674 88 (definition of an auto var) and later 96 (memset on this var).
8675 Hence the stack is badly corrumpted. The headers inclusion is to
8676 blame: if I move the awk.h inclusion before GLR's system header
8677 inclusion, the two struct stat have the same size.

8731 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,

8889 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
8890 the same width as int. This reapplies a hunk of the 2002-08-12 patch

8900 * configure.ac (AC_INIT), NEWS: Increment version number.
8901
8902 * doc/bison.texinfo: Minor spelling, grammar, and white space
8903 fixes.
8904 (Symbols): Mention that any negative value returned from yylex
8905 signifies end-of-input. Warn about negative chars. Mention
8906 the portable Standard C character set.
8907
8908 The GNU coding standard says CFLAGS and YFLAGS are reserved
8909 for the installer to set.
8910 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.

8996 to BITSET_WINDEX_MAX.

8998 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
8999 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

9207 name locals "index", as it generates unnecessary warnings on some

9246 to void, to avoid a GCC warning when --disable-nls is in effect.
9247
9248 * src/scan-gram.l: Use strings rather than escapes when possible,
9249 to minimize the number of warnings from xgettext.
9250 (handle_action_dollar, handle_action_at): Don't use isdigit,
9251 as it mishandles negative chars and it may not work as expected
9252 outside the C locale.
9253
9254 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
9255 this is a GCC extension and is not portable to other compilers.

9258 Do not include <ctype.h>; no longer needed.

9260 warnings on OpenBSD 3.0).
9261
9262 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
9263 it's not portable.
9264
9265 * tests/regression.at: Do not use 'cc -c input.c -o input';

9269 exit status as failure, not just exit status 1. Sun C exits
9270 with status 2 sometimes.

12124 not visible.

12142 Don't use %option yylineno: it seems that then Flex imagines
12143 REJECT has been used, and therefore it won't reallocate its

12145 in warnings for `unused: yy_flex_realloc'.

12434 Rely on -1 as separator in yyrhs, instead of 0.
12435 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
12436 twice `Now at end of input', therefore there are two lines less to
12437 expect.

12451 these states are automatically computed from the initial state.
12452 (generate_states): Adjust.
12453 * src/print.c: When reporting a rule number to the user, substract
12454 1, so that the axiom rule is rule 0, and the first user rule is 1.
12455 * src/reduce.c: Likewise.
12456 * src/print_graph.c (print_core): For the time being, just as for

12460 0: `$axiom: START-SYMBOL $'.

12462 number of the states has changed (the final state is no longer
12463 necessarily the last), catch up.

12488 is the eoftoken.

12490 Be sure to preserve the value of the eoftoken.
12491 (reader): Make sure eoftoken is defined.
12492 Initialize nsyms to 0: now eoftoken is created just like the others.
12493 * src/print.c (print_grammar): Don't special case the eof token.
12494 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
12495 lie anyway, albeit pleasant.
12496 * tests/calc.at: Exercise error messages with eoftoken.
12497 Change the grammar so that empty input is invalid.

13338 Because useless nonterminals are now kept alive (instead of being

13348 `shift_symbol', containing the symbol that can be shifted from a
13349 given state.
13350 Deobfuscate, i.e., allocate, use and free `symbol_count' here
13351 only, and...

15734 The location tracking mechanism is precious for parse error
15735 messages. Nevertheless, it is enabled only when `@n' is used in
15736 the grammar, which is a different issue (you can use it in error

15738 be another means to enable it.

15770 Test also `--verbose', `--defines' and `--name-prefix'. Testing
15771 the latter demonstrates a flaw in the handling of non debugging
15772 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
15773 was used in order to simplify:
15774
15775 #if YYDEBUG
15776 if (yydebug)
15777 {
15778 ...

15782 into

15784 if (yydebug)
15785 {
15786 ...
15787 }
15788
15789 unfortunately this leads to a CPP conflict when
15790 `--name-prefix=foo' is used since it produces `#define yydebug
15791 foodebug'.

15841 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
15842 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
15843 difficult and introduced a lot of core dump. It turns out that
15844 Bison used an implementation of `xmalloc' based on `calloc', and
15845 at various places it does depend upon the initialization to 0. I
15846 have not tried to isolate the pertinent places, and all the former
15847 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

169161995-10-15 Richard Stallman <rms@gnu.org>
16917
16918 * src/vmsgetargs.c, src/getargs.c:
16919 Added -n, -k, and -raw switches.
16920 (noparserflag, toknumflag, rawtoknumflag): New variables.
16921
16922 * src/symtab.h (SALIAS):
16923 New #define for adding aliases to %token.
16924 (struct bucket): Added `alias' field.

16929
16930 * src/reader.c (reader_output_yylsp):
16931 New function.
16932 (readgram): Use `#if 0' around code that accepted %command
16933 inside grammar rules: The documentation doesn't allow it,
16934 and it will fail since the %command processors scan for the next %.
16935 (parse_token_decl): Extended the %token
16936 declaration to allow a multi-character symbol as an alias.
16937 (parse_thong_decl): New function.
16938 (read_declarations): Added %thong declarations.
16939 (read_declarations): Handle NOOP to deal with allowing
16940 % declarations as another means to specify the flags.
16941 (readgram): Allow %prec prior to semantics embedded in a rule.
16942 (skip_to_char, read_declarations, copy_definition)
16943 (parse_token_decl, parse_start_decl, parse_type_decl)
16944 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
16945 (get_type_name, copy_guard, copy_action, readgram)
16946 (get_type, packsymbols): Revised most error messages.
16947 Changed `fatal' to `warnxxx' to avoid aborting for error.
16948 Revised and use multiple warnxxx functions to avoid using VARARGS1.
16949 (read_declarations): Improve the error message for
16950 an invalid character. Do not abort.
16951 (read_declarations, copy_guard, copy_action): Use
16952 printable_version to avoid unprintable characters in printed output.
16953 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
16954 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
16955 Allow the type of a non-terminal can be given
16956 more than once, as long as all specifications give the same type.
16957
16958 * src/output.c:
16959 (output_headers, output_trailers, output, output_gram)
16960 (output_rule_data): Implement noparserflag variable.
16961 Implement toknumflag variable.
16962 (output): Call reader_output_yylsp to output LTYPESTR.
16963
16964 * src/main.c (main):
16965 If reader sees an error, don't process the grammar.
16966 (fatals): Updated to not use VARARGS1.
16967 (printable_version, int_to_string, warn, warni, warns, warnss)
16968 (warnsss): New error reporting functions. Avoid abort for error.
16969
16970 * src/lex.h:
16971 Added THONG and NOOP for alias processing.
16972 Added SETOPT for the new code that allows setting options with %flags.
16973
16974 * src/lex.c:
16975 Include getopt.h. Add some extern decls.
16976 (safegetc): New function to deal with EOF gracefully.
16977 (literalchar); new function to deal with reading \ escapes.
16978 (lex): Use literalchar.
16979 (lex): Implemented "..." tokens.
16980 (literalchar, lex, parse_percent_token): Made tokenbuffer
16981 always contain the token. This includes growing the token
16982 buffer while reading an integer.
16983 (parse_percent_token): Replaced if-else statement with percent_table.
16984 (parse_percent_token): Added % declarations as another
16985 way to specify the flags -n, -l, and -r. Also added hooks for
16986 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
16987 major changes to files.c.
16988 (lex) Retain in the incoming stream a character following
16989 an incorrect '/'.
16990 (skip_white_space, lex): Revised most error messages
16991 and changed fatal to warn to avoid aborting.
16992 (percent_table): Added %thong declarations.
16993
16994 * src/gram.h: Comment changes.
16995
16996 * src/files.c (openfiles, open_extra_files, done):
16997 Add faction flag
16998 and actfile file. Handle noparserflag. Both for -n switch.
16999
