3 Fix problems with translating English-language diagnostics.
4 * bootstrap: Fix bug introduced in recent bootstrap changes, with
5 respect to bison-runtime pot generation. The YY_ stuff
6 wasn't being captured.
7 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
8 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
9 * runtime-po/POTFILES.in: Add data/push.c.

16
17 Automatically generated dependencies are important even
18 when all of the sources in a directory come from gnulib.
19 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
20 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
21
22 2006-09-23 Jim Meyering <jim@meyering.net>
23
24 * bootstrap (gnulib_tool_options): Add "--local-dir gl".

56 * bootstrap (symlink_to_gnulib): New function.
57 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
58 to copies-of-gnulib.
59 (cp_mark_as_generated, slurp, gnulib_files):
60 Avoid making a copy if it's the same as the old version.
61 (gnulib_files): Add support for this variable (used by Bison).

71 Use some of gnulib's new modules, taken from coreutils.
72
73 * bootstrap: Sync from coreutils, except add support for gnulib_files.
74 * bootstrap.conf: New file.
75 (gnulib_modules): Add configmake, inttypes, unistd.
76 (XGETTEXT_OPTIONS): Add complain, complain_at,
77 fatal, fatal_at, warn, warn_at, unexpected_end.
78 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
79 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
80 (gl_EARLY): Add.
81 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
82 (gl_INIT): Add
83 (GNULIB_AUTOCONF_SNIPPET): Remove.
84 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
85 the pickiest.
86 * lib/.cvsignore: Add inttypes_.h.
87 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
88 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
89 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
90 no-longer-necessary initializations.
91 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
92 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
93 use the unistd module.
94 * src/system.h: Likewise.
95 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
96 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
97 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
98 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
99 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
100 * src/system.h: Include inttypes.h unconditionally, now that we
101 use the inttypes module. Don't bother to include stdint.h, since
102 inttypes.h now does that for us.
103 (LOCALEDIR): Remove, now that we use the configmake module.
104 * src/getargs.c: Include configmake.h.
105 * src/main.c: Likewise.
106 * src/output.c: Likewise.
107 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,

111 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
112 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
113
114 * src/parse-gram.y (symbol_declaration): Don't put statements
115 before declarations; it's not portable to C89.
116 * src/scan-code.l (handle_action_at): Likewise.
117
118 * src/scan-code.l: Always initialize braces_level; the old code
119 left it uninitialized and therefore had undefined behavior.
120
121 Don't attempt to redefine 'assert', since it runs afoul of
122 systems where standard headers (mistakenly) include <assert.h>.
123 Instead, define and use our own alternative, called 'aver'.
124 * src/reader.c: Don't include assert.h, since we no longer
125 use assert.
126 * src/scan-code.l: Likewise.
127 * src/system.h (assert): Remove, replacing with....
128 (aver): New function, taking a bool arg. All uses changed.
129 * src/tables.c (pack_vector): Ensure that aver arg is bool,
130 not merely an integer.

135 * data/c.m4 (YYPUSH): New.
136 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
137 * src/getargs.c (push_parser): New var.
138 * src/getargs.h (push_parser): New declaration.
139 * src/output.c (prepare): Add macro insertion of `push_flag'.
140 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
141 (prologue_declaration): Parse %push-parser.
142 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
143 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
144 list of removed lines from the traces observed.

152 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
153 "#define YYSTYPE int" that caused "make maintainer-check" to fail
154 due to header ordering dependencies. I don't know why the #define
155 was there.

157 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
158 runtime cost when YYDEBUG is not defined, and so that some tests
159 that used to fail now work. Problem and initial suggestion by
160 Paolo Bonzini.
161 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
162 * data/glr.cc (b4_parser_class_name):
163 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
164 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
165 (yydebug_) [YYDEBUG]: New member.
166 (yycdebug_): Now defined only if YYDEBUG.
167 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
168 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
169 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
170 if YYYDEBUG.
171 (debug_stream, set_debug_stream, debug_level, set_debug_level):
172 Define only if YYDEBUG.
173 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
174 set_debug_level.
175 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
176 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
177 AT_CHECK_CALC_GLR_CC that are working now.

181 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
182 We don't need them in glr.cc, and glr.c defines them.
183 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
184 assumes that defining it to anything is the same as defining
185 it to 1. Problem reported by Paolo Bonzini.

PE
1872006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)

195 * data/glr.c (b4_shared_declarations): Put start-header first,
196 before any #includes that we generate, so that feature-test
197 macros work. Problem reported by Michael Deutschmann in
198 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
199 * data/lalr1.cc: Likewise.
200 * doc/bison.texinfo (Prologue): Document that feature-test macros
201 should be defined before any Bison declarations.
202 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
203 that depend on location.hh after, not before, Bison decls, since
204 we now include location.hh after the first user prologue.
205
3dc5e96b
PE
206 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
207 Sander Brandenburg in
208 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
209 Also, fix minor white space and comment issues.
aef3da86
PE
210 (Prologue): Mention that it's better to define feature-test macros
211 before Bison declarations. Problem reported by Michael Deutschmann.
212
213 * README-cvs: Fix typo: "&" should be "&&". Problem reported
214 by Jim Meyering.
215 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
216 This adjusts to recent gnulib changes.

220 Finish implementation of per-type %destructor/%printer. Discussed
221 starting at

223 and
224 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
225 * NEWS (2.3+): Add a description of this feature to the default
226 %destructor/%printer description.
227 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
228 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
229 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
230 list node contains a semantic type.
231 * src/symtab.c, src/symtab.h: Extend with a table that associates
232 semantic types with their %destructor's and %printer's.
233 (semantic_type_from_uniqstr, semantic_type_get,
234 semantic_type_destructor_set, semantic_type_printer_set): New functions
235 composing the public interface of that table.
236 (symbol_destructor_get, symbol_destructor_location_get,
237 symbol_printer_get, symbol_printer_location_get): If there's no
238 per-symbol %destructor/%printer, look up the per-type before trying
239 the default.
240 * tests/actions.at (Per-type %printer and %destructor): New test case.
241 * tests/input.at (Default %printer and %destructor redeclared):
242 Extend to check that multiple occurrences of %symbol-default in a
243 single %destructor/%printer declaration is an error.
244 (Per-type %printer and %destructor redeclared, Unused values with
245 per-type %destructor): New test cases.

249 Require default %destructor/%printer to be declared using
250 %symbol-default instead of an empty symbol list, and start working on
251 new per-type %destructor/%printer. Discussed at
252 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
253 * NEWS (2.3+): Add %symbol-default to example.
254 * bison.texinfo (Freeing Discarded Symbols): Likewise.
255 (Bison Symbols): Add entry for %symbol-default.
256 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
257 (generic_symlist, generic_symlist_item): New nonterminals for creating
258 a list in which each item is a symbol, semantic type, or
259 %symbol-default.
260 (grammar_declaration): Use generic_symlist in %destructor and %printer
261 declarations instead of symbols.1 or an empty list.
262 (symbol_declaration, precedence_declaration, symbols.1): Update actions
263 for changes to symbol_list.
264 * src/reader.c: Update for changes to symbol_list.
265 * src/scan-code.l: Likewise.
266 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
267 * src/symlist.c, src/symlist.h: Extend such that a list node may
268 represent a semantic type or a %symbol-default in addition to just an
269 ordinary symbol. Add switched functions for setting %destructor's and
270 %printer's.
271 * tests/actions.at, tests/input.at: Add %symbol-default to all default
272 %destructor/%printer declarations.

276 Whether the default %destructor/%printer applies to a particular symbol
277 isn't a question of whether the user *declares* that symbol (in %token,
278 for example). It's a question of whether the user by any means
279 *defines* the symbol at all (by simply using a char token, for
280 example). $end is defined by Bison whereas any other token with token
281 number 0 is defined by the user. The error token is always defined by
282 Bison regardless of whether the user declares it with %token, but we
283 may one day let the user define error as a nonterminal instead.
284 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
285 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
286 the meaning of "user-defined".
287 * tests/actions.at (Default %printer and %destructor for user-declared
288 end token): Rename to...
289 (Default %printer and %destructor for user-defined end token): ...
290 this.
291
292 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
293 computation of whether to apply the default, don't maintain a list of
294 every Bison-defined symbol. Instead, just check for a first character
295 of '$', which a user symbol cannot have, and check for the error token.

299 Don't apply the default %destructor or %printer to the error token,
300 $undefined, or $accept. This change fits the general rule that the
301 default %destructor and %printer are only for user-declared symbols,
302 and it solves several difficulties that are described in the new test
303 cases listed below.
304 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
305 * tests/actions.at (Default %printer and %destructor are not for error
306 or $undefined, Default %printer and %destructor are not for $accept):
307 New test cases.

311 Allow %start after the first rule.
312 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
313 when parsing the first rule.
314 (check_and_convert_grammar): Search for it here after all grammar
315 declarations have been parsed. Skip midrules, which have dummy LHS
316 nonterminals.
317 * src/symtab.c (symbol_is_dummy): New function.
318 * src/symtab.h (symbol_is_dummy): Declare it.

323 Redo some of the previous commit: add back the ability to use
324 non-aliased/undeclared string literals since it might be useful to
325 those declaring %token-table.
326 * src/reader.c (check_and_convert_grammar): Undo changes in previous
327 commit: don't worry about complaints from symbols_pack.
328 * src/symtab.c (symbol_new, symbol_class_set,
329 symbol_check_alias_consistency): Undo changes in previous commit: count
330 each string literal as a new symbol and token, assign it a symbol
331 number, and don't complain about non-aliased string literals.
332 (symbols_pack): Since symbol_make_alias still does not decrement symbol
333 and token counts but does still set aliased tokens to the same number,
334 symbol_pack_processor now leaves empty slots in the symbols array.
335 Remove those slots.
336 * tests/regression.at (Undeclared string literal): Remove test case
337 added in previous commit since non-aliased string literals are allowed
338 again.
339 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
340 remove unnecessary string literal declarations.

345 Don't allow an undeclared string literal, but allow a string literal to
346 be used before its declaration.
347 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
348 symbols_pack complained.
349 * src/symtab.c (symbol_new): Don't count a string literal as a new
350 symbol.
351 (symbol_class_set): Don't count a string literal as a new token, and
352 don't assign it a symbol number since symbol_make_alias does that.
353 (symbol_make_alias): It's not necessary to decrement the symbol and
354 token counts anymore. Don't assume that an alias declaration occurs
355 before any uses of the identifier or string, and thus don't assert that
356 one of them has the highest symbol number so far.
357 (symbol_check_alias_consistency): Complain if there's a string literal
358 that wasn't declared as an alias.
359 (symbols_pack): Bail if symbol_check_alias_consistency failed since
360 symbol_pack asserts that every token has been assigned a symbol number
361 although undeclared string literals have not.
362 * tests/regression.at (String alias declared after use, Undeclared
6d0ef4ec 363 string literal): New test cases.

383 Handle string aliases for character tokens correctly.
384 * src/symtab.c (symbol_user_token_number_set): If the token has an
385 alias, check and set its alias's user token number instead of its own,
386 which is set to indicate the alias. Previously, every occurrence of
387 the character token in the grammar overwrote that alias indicator with
388 the character code.

397 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
398 to prevent failures when building on older platforms.
399 Check for autopoint failure.
400 Set XGETTEXT_OPTIONS to values that check for C format strings,
401 so that translators are warned about them (this also helps
402 prevent core dumps).
403
404 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
405 function, since it simplifies our code a bit.
406
407 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
408 rather than -W, so we don't get bogus warnings about sign comparisons.
409 Add -Wpointer-arith, since that warning is useful (it reports code
410 that does not conform to C89 and that some compilers reject).
411 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,

452 Enable declaration of default %printer/%destructor. Make the parser
453 use these for all user-declared grammar symbols for which the user does
454 not declare a specific %printer/%destructor. Thus, the parser uses it
455 for token 0 if the user declares it but not if Bison generates it as
456 $end. Discussed starting at

461 * NEWS (2.3+): Mention.
462 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
463 declare a %destructor for a mid-rule's semantic value. It's just
464 impossible to declare one specific to it.

477 variables to record the default %destructor and %printer.
478 (symbol_destructor_get, symbol_destructor_location_get,
479 symbol_printer_get, symbol_printer_location_get): New functions to
480 compute the appropriate %destructor and %printer for a symbol.

502 Make the skeletons consistent in how they pop the end token and invoke
503 its %destructor.
504 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
505 state, which has token number 0, since this would invoke the
506 %destructor for the end token.
507 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
508 until after shifting the end token, or else it won't be popped.
509 * data/yacc.c (yyparse): Likewise.

812 where necessary.
813 * src/symlist.c (symbol_list_new): Initialize new midrule-related
814 members.
815 (symbol_list_length): Now that this is invoked after all rules have
816 been parsed, a NULL symbol (rather than a NULL symbol list node)
817 terminates a rule. symbol_list_print already does this correctly.
818 * src/symlist.h (symbol_list.midrule_parent_rule,
819 symbol_list.midrule_parent_rhs_index): New members so that midrules can
820 remember their relationships with their parents.

822 fixed by the above patch.

824 implementing...
825 (Unused values): ... this old test case and...
826 (Unused values before symbol declarations): ... this new test case.
827 This one is the same as `Unused values' except that all symbol
828 declarations appear after the rules in order to catch the rest of the
829 errors fixed by the above patch.

1347 corresponding LHS was already resolved, so yyresolveLocations didn't
1348 actually have reason to modify it. Fix this by forcing

2822 Use unlocked I/O for a minor performance improvement on hosts like
2823 GNU/Linux and Solaris that support unlocked I/O. The basic idea

3435 the 2005-04-17 change, which is now accomplished (mostly) via
3436 changes in the parsers as described above.

3442 Fix more problems reported by twlevo@xs4all.nl.
3443 * tests/cxx-type.at: Don't pipe output of ./types through sed to
3444 remove trailing spaces. This loses the exit status of ./types,
3445 and isn't needed since ./types shouldn't be emitting trailing
3446 spaces.
3447 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
3448 as the stack isn't valid in that case.

3461 overly-picky compilers that reject 'char *foo = "bar";'.
3462
3463 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
3464 to FILE * parameter, not to stderr. This fixes a typo introduced
3465 in the 2005-07-12 change.
3466

3483 * data/lalr1.cc (yyerrlab): Likewise.
3484 * data/glr.c (yyparse): Pop everything off the stack before
3485 freeing it, so that destructors get called properly.

3507 report it separately rather than in a single diagnostic; this
3508 eases translation.

3518 msgids; there's little point to having them translated, since they
3519 can be understood only by someone who can read the
3520 (English-language) source code.
3521
3522 Generate runtime-po/bison-runtime.pot automatically, so that we
3523 don't have to worry about garbage getting in that file. We'll
3524 make sure after the next official release that old msgids don't

3527
3528 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
3529 Now auto-generated.
3530 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
3531 Fix typos in explanations of the runtime file.
3532 * bootstrap: Change gettext keyword from YYI18N to YY_.
3533 Use standard Makefile.in.in in runtime-po, since we'll arrange
3534 for backward-compatible bison-runtime.po files in a different way.
3535 * data/glr.c (YY_): New macro, from yacc.c.
3536 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
3537 Translate messages intended for users.
3538 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
3539 the wording in the other skeletons. We don't know that the memory
3540 is virtual.
3541 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
3542 Use same method that yacc.c uses.
3543 Don't translate debugging messages.
3544 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
3545 it doesn't work (yet), and requires C++ expertise to fix.
3546 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
3547 Move defn to a more logical place, to be consistent with other
3548 skeletons.
3549 Don't translate debugging messages.
3550 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
3551 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
3552 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
3553 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

3555 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
3556 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
3557 void, not int.
3558 * tests/glr-regression.at (Badly Collapsed GLR States):
3559 Likewise.
3560 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
3561 yylex should return 0 at EOF rather than aborting.

3563 Improve tests for stack overflow in GLR parser.
3564 Problem reported by twlevo@xs4all.nl.
3565 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
3566 All uses removed.
3567 (yyStackOverflow): Just longjmp, but with value 2 so that caller
3568 can handle the problem.
3569 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
3570 (yyparse): New local variable yyresult to record the result.
3571 Use result of setjmp to set it, rather than storing itinto
3572 struct.
3573 (yyDone): Remove label.
3574 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
3575 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
3576 if YYABORT is used).
3577 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
3578 yyparse status; put status > 1 into diagnostic.
3579 Check that status==2 works.
3580 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
3581 Use exit status 3 for failure to open (which shouldn't happen).

3596 Print a stack-overflow message and fail instead.
3597 Initialize the line-number information before creating the stack,
3598 so that the stack-overflow message can report line zero safely.

4349 Remove uses of 'short int' and 'unsigned short int'. This raises
4350 some arbitrary limits. It uses more memory but nowadays that's
4351 not much of an issue.

4353 This change does not affect the generated parsers; that's a different
4354 task, as some users will want to conserve memory there.
4355
4356 Ideally we should use size_t to represent all object counts, and

4706 Remove some arbitrary limits on goto numbers and relations.
4707 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
4708 initial values, since they're never used.
4709 (set_goto_map): ngotos is now unsigned, so test for overflow
4710 by seeing whether it wraps around to zero.
4711 * src/lalr.h (goto_number): Now size_t, not short int.
4712 (GOTO_NUMBER_MAXIMUM): Remove.
4713 * src/relation.c (relation_print, traverse, relation_transpose):

4730 of symbol_precedence_set.

4735 (symbol_make_alias): Don't set the type of the alias, let

4738 type_location.

4757 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
4758 whether the reducion was empty or not. This leaves room to
4759 improve the use of YYLLOC_DEFAULT in such a case.
4760 lalr1.cc is still experimental, so changing this is acceptable.
4761 And finally, there are probably not many users who changed the
4762 handling of locations in GLR, so changing is admissible too.
4763
4764 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
4765 empty reduction, set @$ to an empty location ending the previously
4766 stacked symbol.
4767 Adjust uses to make sure the code is triggered on empty
4768 reductions.
4769 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
4770 expected output: empty reductions have empty locations.

4832 parse" message before any action.
4833 Honor %initial-action.
4834 Initialize the stacks with the lookahead.
4835 * data/yacc.c: Let $$ and @$ in %initial-action designate the

4861 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
4862 value of the result.
4863 (error_start_): Replace with...
4864 (error_range_): this location array.
4865 This allows to replace code relying on the implementation of
4866 locations by portable code.
4867 * data/yacc.c (yylerrsp): Replace with...
4868 (yyerror_range): this.
4869 Every time a token is popped, update yyerror_range[0], to have an
4870 accurate location for the error token.
4871 * data/glr.c (YY_LOCATION_PRINT): New.
4872 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
4873 deference a pointer.
4874 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
4875 report the location in %printers.

4884 Also, return reverse iterators so that when displaying the stack
4885 we display its bottom first.

4892 Have more complete shift traces.
4893
4894 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
4895 to report Shifts instead of ad hoc YYDPRINTF invocations,
4896 including for the error token.
4897 * data/lalr1.cc (symprint_): Output the location.
4898 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
4899 output the location within the %printer.
4900 Activate GLR tests, at least to make sure they compile properly.
4901 They still don't pass though.
4902 * tests/calc.at: Adjust expect verbose output, since now "Entering
4903 state..." is on a different line than the "Shifting" message.

49052004-09-08 Akim Demaille <akim@epita.fr>
4906
4907 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
4908 Bison directive from the Bison file to the invocation of this
4909 macro, so that these directives are passed to
4910 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
4911 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
4912 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
4913 the extra Bison directives instead of the whole series.
4914 Change the grammar so that there are recoverable errors, and
4915 unrecoverable errors. Now we can have the parser give up before
4916 consuming the whole input. As a result we now can observe that
4917 the lookahead is freed when needed.
4918 Change the parser source to parse argv[1] instead of a hard coded
4919 string.
4920 Simplify yylex, and give a value and location to EOF.
4921 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
4922 passed directives already coded in the file.
4923 Add some tests to check the location of "error".
4924 For some tests, the C++ parser is correct, and not yacc.c.
4925 For other tests, they provide different, but unsatisfying, values,
4926 so keep the C++ value so that at least one parser is "correct"
4927 according to the test suite.
4928 (Actions after errors): Remove, this is subsumed by the
4929 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

5107 Spent a few hours checking out which prerequisite versions the
5108 current sources actually require. I went all the way back to
5109 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
5110 a seemingly endless set of combinations of versions more recent
5111 than that. The bottom line is that the current sources require
5112 fairly recent versions of the build tools, and it'll be some work
5113 to change this.
5114 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
5115 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
5116 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
5117 Add comments explaining why those particular versions are
5118 currently needed.

5153 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
5154 autopoint's.

5502 There's no need to mention top_builddir since Automake does that
5503 for us.

5629 When reducing initial empty rules, Bison parser read an initial
5630 location that is not defined. This results in garbage, and that
5631 affects Bison's own parser. Therefore we need (i) to extend Bison
5632 to support a means to initialize this location, and (ii) to use
5633 this CVS Bison to fix CVS Bison's parser.

5682 merely falling thru the default error handling mechanism.
5683 (yyerrorlab): New label, with the old contents of YYERROR,

26ec81e0

5928 The problem was that GLR parsers did not conform to the C standard,
5929 because actions like { $1 = $2 + $3; } expanded to expressions
5930 that invoked YYFILL in separate subexpressions, and YYFILL assigned
5931 to a local variable. The C standard says that expressions
5932 like (var = f ()) + (var = f ()) have undefined behavior.
5933 Another problem was that GCC sometimes issues warnings that
5934 yyfill and its parameters are unused.
5935
5936 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
5937 as possibly unused.
5938 (yyfill): New function.
5939 (YYFILL): Use it.
5940 (yyuserAction): Change type of yynormal to bool, so that it matches
5941 the new yyfill signature. Mark it as possibly unused.

5944 Follow up on a bug I reported in February, where a Bison-generated
5945 parser can loop. Provide a test case and a fix for yacc.c. I
5946 don't have a fix for lalr1.cc or for glr.c, unfortunately.
5947 The original bug report is in:

5950 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
5951 macro's size was becoming unwieldy.
5952 (yyerrlab): Do not discard an empty lookahead symbol, as this
5953 might destroy garbage.
5954 (yyerrorlab): New label, with the old contents of YYERROR,
5955 plus the following change: pop the stack of rhs corresponding
5956 to the production that invoked YYERROR. That is how Yacc
5957 behaves, and POSIX requires this behavior.
5958 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
5959 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
5960 Define 'alarm' to do nothing if unistd.h is not available.
5961 Add a new rule "exp: '-' error;" to test the above change to
5962 data/yacc.c. Use 'alarm' to abort any test taking longer than
5963 10 seconds, as it's probably looping.
5964 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
5965 Also, the new yacc.c generates two fewer diagnostics for an
5966 existing test.

6210 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
6211 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
6212 cursor, instead of leaving it undefined. This fixes a bug

6317 not loc->end, since loc->end might contain garbage and this leads
6318 to undefined behavior on some platforms.

6320 depend on *loc, so that the reader doesn't give the the false
6321 impression that *loc is initialized.
6322 (<INITIAL>"%%"): Do not bother setting code_start, since its value

6330 then it starts with the second %%'s beginning, instead of its end.

6593 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
6594 we don't need to worry about yyerrlab1 being reported as an
6595 "unused label" by non-GCC C compilers. The downside is that if
6596 locations are used then a couple of statements are duplicated each
6597 time YYERROR is invoked, but the upside is that the warnings
6598 should vanish.
6599 (yyerrlab1): Move code to YERROR.
6600 (yyerrlab2): Remove. Change uses back to yyerrlab1.

6614 when the stacks contain one element, as the loop would otherwise
6615 free the last state, and then use the top state (the one we just
6616 popped). This means that the initial elements will not be freed
6617 explicitly, as is the case in yacc.c; it is not a problem, as
6618 these elements have fake values.

6727 * doc/bison.texinfo (Understanding): Use Yacc style for
6728 conflict reports. Also, use new way of locating rules.
6729 * src/conflicts.c (conflict_report):
6730 Renamed from conflict_report_yacc, removing the old
6731 'conflict_report'. Translate the entire conflict report at once,
6732 so that we don't assume that "," has the same interpretation in
6733 all languages.
6734 (conflicts_output): Use Yacc-style conflict report for each state,
6735 instead of our more-complicated style.
6736 (conflicts_print): Use Yacc-style conflict report, except print
6737 the input file name when not emulating Yacc.
6738 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
6739 Conflicted Reduction, %expect not enough, %expect too much,

6752 This problem was originally reported by Paul Hilfinger in

6755 * data/yacc.c (yyparse): New local var yylerrsp, to record the
6756 top of the location stack's error locations.
6757 (yyerrlab): Set it. When discarding a token, push its location
6758 onto yylerrsp so that we don't lose track of the error's end.
6759 (yyerrlab1): Now is only the target of YYERROR, so that we can
6760 properly record the location of the action that failed. For GCC
6761 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
6762 GCC warning about yyerrlab1 being unused if YYERROR is unused.
6763 (yyerrlab2): New label, which yyerrlab now falls through to.
6764 Compute the error's location by applying YYLLOC_DEFAULT to
6765 the locations of all the symbols that went into the error.
6766 * doc/bison.texinfo (Location Default Action): Mention that
6767 YYLLOC_DEFAULT is also invoked for syntax errors.
6768 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
6769 Error locations include the locations of all the tokens that were
6770 discarded, not just the last token.

6827 If the user does not define YYSTYPE as a macro, Bison now declares it
6828 using typedef instead of defining it as a macro. POSIX requires this.
6829 For consistency, YYLTYPE is also declared instead of defined.
6830
6831 %union directives can now have a tag before the `{', e.g., the
6832 directive `%union foo {...}' now generates the C code
6833 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
6834 The default union tag is `YYSTYPE', for compatibility with Solaris 9
6835 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
6836 instead of `yyltype'.
6837
6838 `yystype' and `yyltype' are now obsolescent macros instead of being
6839 typedefs or tags; they are no longer documented and will be
6840 withdrawn in a future release.

6849 * data/yacc.c: Likewise.
6850

6852 does not specify a union tag. This is for compatibility with
6853 Solaris 9 yacc.

6858 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,

6872 has (or usually has) an immediately-following braced code.

6874 to return when scanning braced code.

7480 ((...));' if a single statement is desired (e.g. before `else').
7481 Work around GCC warnings by surrounding corresponding calls with
7482 {} if needed.

7833 Use new @ escapes consistently. Represent brackets with @{ and @}
7834 rather than @<:@ and @:>@, since this works a bit better with dumb
7835 editors like vi. Represent @ with @@, since @ is now consistently
7836 an escape. Use @oline@ and @ofile@ rather than __oline__ and
7837 __ofile__, to avoid unexpected expansions. Similarly, use @output
7838 rather than #output.
7839
7840 * data/c.m4 (b4_copyright): Omit file name from comment, since
7841 the file name could contain "*/".
7842 (b4_synclines_flag): Don't quote the 2nd argument; it should already
7843 be quoted. All uses changed.

7857 mishandled funny characters in file names, and anyway it isn't
7858 needed any more.

7884 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
7885 Use new escapes @{ and @} for [ and ].
7886
7887 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
7888 them with auto vars.
7889 Switch to new escape scheme, where @ is the escape character uniformly.
7890 Abort if a stray escape character is found. Avoid unbounded input
7891 buffer when parsing non-escaped text.

7902 table.
7903 (yygetLRActions, yyrecoverParseError): Use them.

7905 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
7906 counted in the token inserted at end of file. Now takes
7907 location_t *, not location_t, so that the location can be
7908 adjusted. All uses changed.

7928
7929 Remove nounput option. At an unexpected end of file, we now unput

8157 * src/reader.c: Don't include quote.h; not needed.
8158 (get_merge_function): Reword warning to be consistent with
8159 type clash diagnostic in grammar_current_rule_check.

8162 bug in trigraph handling.

8165 escape "[" as "@<:@" and likewise for "]".

8168 assuming C89 or better, and C89 guarantees errno.

8174 * src/files.h (xfclose): Return void, not int, since it always
8175 returned zero.
8176 * src/files.c (xfclose): Likewise. Report I/O error if ferror
8177 indicates one.
8178 * src/output.c (output_skeleton): Use xfclose rather than fclose
8179 and ferror. xfclose now checks ferror.
8180
8181 * data/glr.c (YYLEFTMOST_STATE): Remove.
8182 (yyreportTree): Use a stack-based leftmost state. This avoids
8183 our continuing battles with bogus warnings about initializers.

8245 The last OS that we could find where this wouldn't work is
8246 SunOS 3.5, and that's too old to worry about now.
8247
8248 * data/glr.c (struct yyltype): Define members even when not
8249 doing locations. This is more consistent with yacc.c, and it
8250 works around the following bug reports:

8294 * src/getargs.c (usage): Likewise.
8295
8296 * src/getargs.c (getargs): When there are too few operands, report
8297 the last one. When there are too many, report the first extra
8298 one. This is how diffutils does it.

8310 Include <limits.h> unconditionally, since it's guaranteeed even
8311 for a freestanding C89 compiler.

8622 Let nondeterministic skeletons be usable with deterministic
8623 tables.
8624
8625 With the patch, GAWK compiled by GCC without -O2 passes its test
8626 suite using a GLR parser driven by LALR tables. It fails with -O2
8627 because `struct stat' gives two different answers on my machine:
8628 88 (definition of an auto var) and later 96 (memset on this var).
8629 Hence the stack is badly corrumpted. The headers inclusion is to
8630 blame: if I move the awk.h inclusion before GLR's system header
8631 inclusion, the two struct stat have the same size.

8685 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,

9203 to minimize the number of warnings from xgettext.
9204 (handle_action_dollar, handle_action_at): Don't use isdigit,
9205 as it mishandles negative chars and it may not work as expected
9206 outside the C locale.
9207
9208 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
9209 this is a GCC extension and is not portable to other compilers.

9212 Do not include <ctype.h>; no longer needed.

9217 it's not portable.

12053 * src/parse-skel.y: Request a pure parser, locations, and prefix
12054 renaming.

12056 type mismatches, simplify.

12076 problems: because Flex includes the headers *before* us,
12077 _GNU_SOURCE is not defined by config.h, and therefore strndup was
12078 not visible.

12096 Don't use %option yylineno: it seems that then Flex imagines
12097 REJECT has been used, and therefore it won't reallocate its
12098 buffers (which makes no other sense to me than a bug). It results
12099 in warnings for `unused: yy_flex_realloc'.

12851 * tests/torture.at (GNU AWK Grammar): New.
12852 * tests/sets.at (Nullable): New.

12856 Work around Autotest bugs.
12857
12858 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
12859 frame, because Autotest understand lines starting with a `+' as
12860 traces from the shell. Then, they are not processed properly.
12861 Admittedly an Autotest bug, but we don't have time to wait for
12862 Autotest to catch up.

12879 * src/print_graph.c (print_core): Complete the set of items via
12880 closure. The next-to-final and final states are still unsatisfying,
12881 but that's to be addressed elsewhere.
12882 No longer output the rule numbers, but do output the state number.
12883 A single loop for the shifts + gotos is enough, but picked a
12884 distinct color for each.

13292 Because useless nonterminals are now kept alive (instead of being
13293 `destroyed'), we now sometimes examine them, and store information
13294 related to them. Hence we need to know their number, and adjust

13300 `symbol_count' was used for two different purpose: once to count
13301 the number of occurrences of each symbol, and later reassigned to
13302 `shift_symbol', containing the symbol that can be shifted from a
13303 given state.
13304 Deobfuscate, i.e., allocate, use and free `symbol_count' here
13305 only, and...
13306 (new_itemsets): Allocate `shift_symbol' here.
13307 (allocate_itemsets): symbol_count includes useless nonterminals.

13310 be null.

13452
13453 (yyparse): Don't dump core if alloca or malloc fails; instead, report

13455 three stacks, instead of allocating three blocks; this typically is
13456 faster and reduces fragmentation.

15688 The location tracking mechanism is precious for parse error
15689 messages. Nevertheless, it is enabled only when `@n' is used in
15690 the grammar, which is a different issue (you can use it in error

15724 Test also `--verbose', `--defines' and `--name-prefix'. Testing
15725 the latter demonstrates a flaw in the handling of non debugging
15726 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
15727 was used in order to simplify:
15728
15729 #if YYDEBUG
15730 if (yydebug)
15731 {
15732 ...

15738 if (yydebug)
15739 {
15740 ...
15741 }
15742

15795 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
15796 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
15797 difficult and introduced a lot of core dump. It turns out that
15798 Bison used an implementation of `xmalloc' based on `calloc', and
15799 at various places it does depend upon the initialization to 0. I
15800 have not tried to isolate the pertinent places, and all the former
15801 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

16925 Added THONG and NOOP for alias processing.
16926 Added SETOPT for the new code that allows setting options with %flags.
16927
16928 * src/lex.c:

16941 major changes to files.c.
16942 (lex) Retain in the incoming stream a character following
16943 an incorrect '/'.
