1 2002-11-03 Paul Eggert <eggert@twinsun.com>
3 * src/reader.c (get_merge_function, grammar_current_rule_check):
4 Use consistent diagnostics for reporting type name clashes.
5 Quote the types with <>, for consistency with Yacc.
6 * tests/input.at (Type Clashes): Adjust to diagnostic changes.

18 (b4_lpure_formals): New.
19 Use b4_identification.
20 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
21 b4_user_formals and b4_user_args.
22 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
23 (yyreportAmbiguity): When using a pure parser, also need
24 the location, and the parse-params.
26 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
27 When using a pure parser, also need the parse-params.
29 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
30 (%pure-parser + %parse-param) LALR and GLR parsers.
31 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
32 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
33 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
34 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
35 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
36 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.

41 Document %error-verbose, deprecate YYERROR_VERBOSE.
43 2002-11-03 Akim Demaille <akim@epita.fr>
45 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
46 AT_CHECK_CALC_GLR invocations to use % directives, instead of
48 * tests/cxx-type.at: Formatting changes.
50 2002-11-03 Paul Eggert <eggert@twinsun.com>
52 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
53 to count columns correctly, and to check for invalid inputs.
55 Use mbsnwidth to count columns correctly. Account for tabs, too.
57 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
58 (extend_location): New function.
61 Handle CRLF in C code rather than in Lex code.
62 (YY_INPUT): New macro.
63 (no_cr_read): New function.
65 Scan UCNs, even though we don't fully handle them yet.
66 (convert_ucn_to_byte): New function.
68 Handle backslash-newline correctly in C code.
69 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
70 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
72 (tag, splice): New EREs. Do not allow NUL or newline in tags.
73 Use {splice} wherever C allows backslash-newline.
74 YY_STEP after space, newline, vertical-tab.
75 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
77 (letter, id): Don't assume ASCII; e.g., spell out a-z.
79 ({int}, handle_action_dollar, handle_action_at): Check for integer
82 (YY_STEP): Omit trailing semicolon, so that it's more like C.
84 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
85 as well as \000. Check for UCHAR_MAX, not 255.
86 Allow \x with an arbitrary positive number of digits, as in C.
87 Check for overflow here.
88 Allow \? and UCNs, for compatibility with C.
90 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
91 with quote slot used by complain_at.
93 * tests/input.at: Add tests for backslash-newline, m4 quotes
94 in symbols, long literals, and funny escapes in strings.
96 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
97 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
98 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
99 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
100 * m4/mbswidth.m4: New file, from GNU coreutils.
102 * doc/bison.texinfo (Grammar Outline): Document // comments.

105 (Actions): Document that trigraphs have no special meaning.
107 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
110 2002-11-02 Paul Eggert <eggert@twinsun.com>
112 * src/reader.c: Don't include quote.h; not needed.

114 type clash diagnostic in grammar_current_rule_check.
116 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
117 bug in trigraph handling.
119 * src/output.c (prepare_symbols): When printing token names,
120 escape "[" as "@<:@" and likewise for "]".
122 * src/system.h (errno): Remove declaration, as we are now
123 assuming C89 or better, and C89 guarantees errno.
125 2002-10-30 Paul Eggert <eggert@twinsun.com>
127 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
128 Check for close failures.
129 * src/files.h (xfclose): Return void, not int, since it always
131 * src/files.c (xfclose): Likewise. Report I/O error if ferror
133 * src/output.c (output_skeleton): Use xfclose rather than fclose
134 and ferror. xfclose now checks ferror.
136 * data/glr.c (YYLEFTMOST_STATE): Remove.
137 (yyreportTree): Use a stack-based leftmost state. This avoids
138 our continuing battles with bogus warnings about initializers.
140 2002-10-30 Akim Demaille <akim@epita.fr>
142 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
145 2002-10-24 Paul Eggert <eggert@twinsun.com>
149 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
150 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
151 we use malloc. Don't assume 'A' through 'Z' are contiguous.
152 Don't assume strdup exists; POSIX says its an XSI extension.
153 Check for buffer overflow on input.
155 2002-10-24 Akim Demaille <akim@epita.fr>
157 * src/output.c (output_skeleton): Don't disable M4sugar comments
158 too soon: it results in comments being expanded.
159 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
162 2002-10-24 Akim Demaille <akim@epita.fr>
164 * data/yacc.c (m4_int_type): New.
165 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
166 char' as only yacc.c wants K&R portability.
167 * data/glr.c (yysigned_char): Remove.
168 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
169 Reported by Quoc Peyrot.
171 2002-10-23 Paul Eggert <eggert@twinsun.com>
173 * src/main.c (main): With --trace=time, report times even if a
174 non-fatal error occurs. Formerly, the times were reported in some
175 such cases but not in others.
176 * src/reader.c (reader): Just return if a complaint has been issued,
177 instead of exiting, so that 'main' can report times.
179 2002-10-22 Akim Demaille <akim@epita.fr>
181 * src/system.h: Include sys/types.
182 Reported by Bert Deknuydt.
184 2002-10-23 Paul Eggert <eggert@twinsun.com>
186 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
187 Suggested by Art Haas.
189 2002-10-22 Paul Eggert <eggert@twinsun.com>
191 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
192 decl; not needed any more.
193 * src/main.c (main): Use return to exit, undoing yesterday's change.
194 The last OS that we could find where this wouldn't work is
195 SunOS 3.5, and that's too old to worry about now.
197 * data/glr.c (struct yyltype): Define members even when not
198 doing locations. This is more consistent with yacc.c, and it
199 works around the following bug reports:
200 http://mail.gnu.org/pipermail/bug-bison/2002-October/001764.html
201 http://mail.gnu.org/pipermail/bug-bison/2002-October/001769.html
202 and I hope it also fixes this bug report:
203 http://mail.gnu.org/pipermail/bug-bison/2002-October/001748.html
205 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
206 @acronym consistently. Standardize on "Yacc" instead of "YACC",
207 "Algol" instead of "ALGOL". Give a bit more history about BNF.
209 2002-10-22 Akim Demaille <akim@epita.fr>
213 2002-10-21 Paul Eggert <eggert@twinsun.com>
215 Be consistent about 'bool'; the old code used an enum in one
216 module and an int in another, and this violates the C standard.
217 * m4/stdbool.m4: New file, from coreutils 4.5.3.
218 * configure.ac (AC_HEADER_STDBOOL): Add.
219 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
220 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
221 * src/symtab.c (hash_compare_symbol_t): Likewise.
222 * src/system.h (bool, false, true): Use a definition consistent
223 with ../lib/hash.c. All uses changed.
225 * src/complain.c (warning_issued): Renamed from warn_message_count,
226 so that we needn't worry about integer overflow (!).
227 Now of type bool. All uses changed.
228 (complaint_issued): Renamed from complain_message_count; likewise.
230 * src/main.c (main): Use exit to exit with failure.
232 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
234 * src/main.c (main): Likewise.
235 * src/getargs.c (getargs): Likewise.
236 * src/reader.c (reader): Likewise.
238 * src/getarg.c (getargs): Remove duplicate code for
239 "Try `bison --help'".
241 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
242 What was that "2" for?
244 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
245 * src/getargs.c (usage): Likewise.
247 * src/getargs.c (getargs): When there are too few operands, report
248 the last one. When there are too many, report the first extra
249 one. This is how diffutils does it.
251 2002-10-20 Paul Eggert <eggert@twinsun.com>
254 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
255 * src/complain.c (VA_START): Remove. Assume prototypes.
256 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
257 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
258 fatal): Assume prototypes.
259 * src/complain.h: Assume prototypes.
260 * src/system.h (PARAMS): Remove.
261 Include <limits.h> unconditionally, since it's guaranteeed even
262 for a freestanding C89 compiler.
263 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
264 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
266 2002-10-20 Akim Demaille <akim@epita.fr>
268 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
269 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
270 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
271 (yyresolveStates, yyresolveAction, yyresolveStack)
272 (yyprocessOneStack): Use them.
273 (yy_reduce_print): New.
274 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
276 2002-10-20 Akim Demaille <akim@epita.fr>
278 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
279 arguments and output `void'.
280 (b4_c_function): Rename as...
281 (b4_c_function_def): this.
282 (b4_c_function_decl, b4_c_ansi_function_def)
283 (b4_c_ansi_function_decl): New.
284 Change the interpretation of the arguments: before `int, foo', now
286 * data/yacc.c (yyparse): Prototype and define thanks to these.
287 Adjust b4_c_function_def uses.
288 * data/glr.c (yyparse): Likewise, but ANSI only.
290 2002-10-20 Akim Demaille <akim@epita.fr>
292 * src/output.c (prepare): Move the definition of `tokens_number',
293 `nterms_number', `undef_token_number', `user_token_number_max'
295 (prepare_tokens): Here.
296 (prepare_tokens): Rename as...
297 (prepare_symbols): this.
298 (prepare): Move the definition of `rules_number' to...
299 (prepare_rules): here.
300 (prepare): Move the definition of `last', `final_state_number',
301 `states_number' to...
302 (prepare_states): here.
303 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
305 2002-10-20 Akim Demaille <akim@epita.fr>

309 2002-10-20 Akim Demaille <akim@epita.fr>
311 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
314 2002-10-20 Akim Demaille <akim@epita.fr>
316 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
317 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
319 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
321 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
322 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
325 2002-10-19 Paul Eggert <eggert@twinsun.com>
327 Do not create a temporary file, as that involves security and
328 cleanup headaches. Instead, use a pair of pipes.
329 Derived from a suggestion by Florian Krohm.
330 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
331 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
332 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.

341 (output_skeleton): Use pipe rather than temporary file for m4 input.
342 Check that m4sugar.m4 is readable, to avoid deadlock.
343 Check for pipe I/O error.
344 * src/scan-skel.l (readpipe): Remove decl.
345 (scan_skel): New function, to be used in place of m4_invoke.
346 Read from stream rather than file.
348 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
349 float, as this generates a warning on Solaris 8 + GCC 3.2 with
350 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
351 this generates a more-accurate value anyway.
353 * lib/timevar.c (timervar_accumulate): Rename locals to
354 avoid confusion with similarly-named more-global.
355 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
357 * src/output.c (prepare): Use xstrdup to convert char const *
358 to char *, to avoid GCC warning.
360 2002-10-19 Akim Demaille <akim@epita.fr>
362 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
363 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
364 Use them to have `calc.y' ready for %pure-parser.
365 * data/yacc.c (YYLEX): Pass a yylex return type to
368 2002-10-19 Akim Demaille <akim@epita.fr>
370 Prototype support of %lex-param and %parse-param.
372 * src/parse-gram.y: Add the definition of the %lex-param and
373 %parse-param tokens, plus their rules.
374 Drop the `_' version of %glr-parser.
376 * src/scan-gram.l (INITIAL): Scan them.
377 * src/muscle_tab.c: Comment changes.
378 (muscle_insert, muscle_find): Rename `pair' as `probe'.
379 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
380 (muscle_entry_s): The `value' member is no longer const.
381 Adjust all dependencies.
382 * src/muscle_tab.c (muscle_init): Adjust: use
383 MUSCLE_INSERT_STRING.
384 Initialize the obstack earlier.
385 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
386 (muscle_pair_list_grow): New.
387 * data/c.m4 (b4_c_function_call, b4_c_args): New.
388 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
389 * tests/calc.at: Use %locations, not --locations.
390 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
392 2002-10-19 Akim Demaille <akim@epita.fr>
394 * src/getargs.c (usage): Take status as argument and exit
396 Report the traditional `Try ... --help' message when status != 0.
397 (usage, version): Don't take a FILE * as arg, it is pointless.
398 (getargs): When there is an incorrect number of arguments, make it
399 an error, and report it GNUlically thanks to `usage ()'.
401 2002-10-18 Paul Eggert <eggert@twinsun.com>
403 * data/glr.c (yyreportParseError): Don't assume that sprintf
404 yields the length of the printed string, as this is not true
405 on SunOS 4.1.4. Reported by Peter Klein.
407 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
408 * tests/conflicts.at (%nonassoc and eof): Likewise.
409 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
411 2002-10-17 Akim Demaille <akim@epita.fr>
413 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
414 * src/getargs.c (trace_types, trace_args): Adjust.
415 * src/reader.c (grammar_current_rule_prec_set)
416 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
417 Standardize error messages.
419 (reader): Use trace_flag to enable scanner/parser debugging,
420 instead of an adhoc scheme.
421 * src/scan-gram.l: Remove trailing debugging code.
423 2002-10-16 Paul Eggert <eggert@twinsun.com>
425 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
428 * NEWS: Officially drop support for building Bison with K&R C,
429 since it didn't work anyway and it's not worth worrying about.
430 * Makefile.maint (wget_files): Remove ansi2knr.c.
431 (ansi2knr.c-url_prefix): Remove.
432 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
433 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
434 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
436 2002-10-15 Paul Eggert <eggert@twinsun.com>
438 Stop using the "enum_" trick for K&R-style function definitions;
439 it confused me, and I was the author! Instead, assume that people
440 who want to use K&R C compilers (when using these modules in GCC,
441 perhaps?) will run ansi2knr.
443 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
444 All uses of "enum_" changed to "enum ".
445 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
446 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
448 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

455 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
456 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
457 Use function prototypes; this removes the need for declaring
458 static functions simply to provide their prototypes.
459 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,
460 bitset_andn_or_, bitset_andn_or_cmp_, bitset_bytes, bitset_copy_,

533 tests/cxx-type.at, tests/headers.at, tests/input.at,
534 tests/regression.at, tests/synclines.at, tests/torture.at:
535 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
536 so that the tests still work even if POSIXLY_CORRECT is set.
537 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
539 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
540 for portability to K&R hosts. Fix typo: signed char is guaranteed
541 only to 127, not to 128.
542 * data/glr.c (yysigned_char): New type.
543 * data/yacc.c (yysigned_char): Likewise.
544 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
546 2002-10-13 Paul Eggert <eggert@twinsun.com>
548 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
549 true due to limited range of data type" warning from GCC.
551 * data/c.m4 (b4_token_defines): Protect against double-inclusion
552 by wrapping enum yytokentype's definition inside #ifndef
553 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
555 2002-10-13 Akim Demaille <akim@epita.fr>
557 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):

573 Let nondeterministic skeletons be usable with deterministic
576 With the patch, GAWK compiled by GCC without -O2 passes its test
577 suite using a GLR parser driven by LALR tables. It fails with -O2
578 because `struct stat' gives two different answers on my machine:
579 88 (definition of an auto var) and later 96 (memset on this var).
580 Hence the stack is badly corrumpted. The headers inclusion is to
581 blame: if I move the awk.h inclusion before GLR's system header
582 inclusion, the two struct stat have the same size.
584 * src/tables.c (pack_table): Always create conflict_table.
585 (token_actions): Always create conflict_list.
586 * data/glr.c (YYFLAG): Remove, unused.

602 Tweak some trace messages to match yacc.c's.
604 2002-10-13 Akim Demaille <akim@epita.fr>
606 GLR parsers sometimes raise parse errors instead of performing the
608 Reported by Charles-Henry de Boysson.
610 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
611 check the length of the traces when %glr.
612 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
614 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
616 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
617 (yyltype): Remove the yy prefix from the member names.
618 (yytable): Complete its comment.
619 (yygetLRActions): Map error action number from YYTABLE from
621 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
622 (which was a bug: it should have been YYTABEL_NINF, and yet it was
623 not satisfying as we could compare an YYACTION computed from
624 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
625 only value for error actions.
626 (yyreportParseError): In verbose parse error messages, don't issue
627 `error' in the list of expected tokens.
628 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
629 next action to perform to match glr.c's decoding.
630 (yytable): Complete its comment.

636 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
637 because the Bison parser reads the second action before reducing
639 * src/scan-gram.l (rule_length): New static var.
640 Use it to keep track of the rule length in the scanner, since
641 we can't expect the parser to be in lock-step sync with the scanner.
642 (handle_action_dollar, handle_action_at): Use this var.
643 * tests/actions.at (Exotic Dollars): Test for the problem.

654 * lib/timevar.c: Update copyright date and clarify comments.
655 (get_time) [IN_GCC]: Keep the GCC version for reference.
657 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
658 GCC version as of today, then merge Bison's changes.
659 Change "GCC" to "Bison" in copyright notice. timevar.def's
660 author is Akim, so change that too.
662 * src/reader.c (grammar_current_rule_check):
663 Don't worry about the default action if $$ is untyped.
664 Prevents bogus warnings reported by Jim Gifford in

697 * lib/lbitset.c: Likewise.
699 * lib/abitset.c (abitset_bytes): Return a size that is aligned
700 properly for vectors of objects. Do not assume that adding a

702 properly aligned for the whole union.
703 * lib/bitsetv.c (bitsetv_alloc): Likewise.
705 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,

741 for enum_bitset_type.

743 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
745 Do not use "struct bitset_struct" to mean different things in
746 different modules. Not only is this confusing, it violates
747 the C Standard, which requires that structure types in different
748 modules must be compatible if one is to be passed to the other.

794 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
795 the same width as int. This reapplies a hunk of the 2002-08-12 patch
796 <http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
797 which was inadvertently undone by the 2002-09-30 patch.

900 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
901 to BITSET_WINDEX_MAX.
903 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,

1109 * lib/bitset_stats.c: Include "gettext.h".

1154 to minimize the number of warnings from xgettext.
1155 (handle_action_dollar, handle_action_at): Don't use isdigit,

1157 outside the C locale.
1159 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
1160 this is a GCC extension and is not portable to other compilers.
1162 * src/system.h (alloca): Use same pattern as ../lib/error.c.
1163 Do not include <ctype.h>; no longer needed.
1164 Do not include <malloc.h>; no longer needed (and generates
1165 warnings on OpenBSD 3.0).
1167 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
1170 * tests/regression.at: Do not use 'cc -c input.c -o input';
1171 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
1173 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
1174 exit status as failure, not just exit status 1. Sun C exits

1197 * tests/conflicts.at, tests/reduce.at: Adjust.

1218 (initialize_LA): this.
1219 (lalr_free): Adjust.
1220 * src/main.c (main): Don't free nullable and derives too early: it
1221 is used by --verbose.
1222 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
1224 2002-08-01 Akim Demaille <akim@epita.fr>

1338 Report rules which are never reduced by the parser: those hidden
1341 * src/LR0.c (save_reductions): Don't make the final state too
1342 different: save its reduction (accept) instead of having a state
1343 without any action (no shift or goto, no reduce).
1344 Note: the final state is now a ``regular'' state, i.e., the
1345 parsers now contain `reduce 0' as default reduction.

1392 * src/reader.h, src/reader.c (gram_error): ... can't get
1393 yycontrol without making too strong assumptions on the parser
1395 * src/output.c (prepare_tokens): Use the real 0th value of
1396 token_translations instead of `0'.
1397 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
1399 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
1400 for the time being: %locations ought to provide it to yyerror.
1402 2002-07-25 Akim Demaille <akim@epita.fr>
1404 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

3773 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
3775 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
3776 (prepare): Given that for the time being changesyntax is not
3777 usable in M4, rename the muscles using `-' to `_'.

3810 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.

3815 Fix `%nonassoc and eof'.

3988 The ISO C++ standard is extremely clear about it: stderr is
3989 considered a macro, not a regular symbol (see table 94 `Header
3990 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
3991 Therefore std:: does not apply to it. It still does with fprintf.
3992 Also, s/cstdio.h/cstdio/.
3994 2002-01-03 Akim Demaille <akim@epita.fr>
3996 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
3997 for non system headers.
3999 2002-01-02 Akim Demaille <akim@epita.fr>
4001 Equip the skeleton chain with location tracking, runtime trace,
4002 pure parser and scanner.
4004 * src/parse-skel.y: Request a pure parser, locations, and prefix
4006 (%union): Having several members with the same type does not help
4007 type mismatches, simplify.
4008 (YYPRINT, yyprint): New.
4009 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
4012 * src/scan-skel.l: Adjust to these changes.
4013 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
4014 (LOCATION_PRINT, skel_control_t): New.
4016 2001-12-30 Akim Demaille <akim@epita.fr>
4018 * src/parse-skel.y: Get rid of the shift/reduce conflict:
4019 replace `gb' with BLANKS.
4020 * src/scan-skel.l: Adjust.
4022 2001-12-30 Akim Demaille <akim@epita.fr>
4024 * src/system.h: We don't need nor want bcopy.
4025 Throw away MS-DOS crap: we don't need getpid.
4026 * configure.in: We don't need strndup. It was even causing
4027 problems: because Flex includes the headers *before* us,
4028 _GNU_SOURCE is not defined by config.h, and therefore strndup was
4030 * lib/xstrndup.c: New.
4031 * src/scan-skel.l: Use it.
4032 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
4033 * src/parse-skel.y: Use %directives instead of #defines.
4035 2001-12-30 Akim Demaille <akim@epita.fr>
4037 * src/skeleton.h: New.
4038 * src/output.c (output_parser, output_master_parser): Remove, dead
4040 * src/output.h (get_lines_number, actions_output, guards_output)
4041 (token_definitions_output): Prototype them.
4042 * src/parse-skel.y: Add the license notice.
4043 Include output.h and skeleton.h.
4044 (process_skeleton): Returns void, and takes a single parameter.
4045 * src/scan-skel.l: Add the license notice.
4047 Don't use %option yylineno: it seems that then Flex imagines
4048 REJECT has been used, and therefore it won't reallocate its
4049 buffers (which makes no other sense to me than a bug). It results
4050 in warnings for `unused: yy_flex_realloc'.
4052 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
4054 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
4055 (MUSCLE_INSERT_PREFIX): ...to there.
4056 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
4057 (MUSCLE_INSERT_PREFIX): Move from here...
4059 * src/bison.hairy: Add a section directive. Put braces around muscle
4060 names. This parser skeleton is still broken, but Bison should not
4061 choke on a bad muscle 'syntax'.
4062 * src/bison.simple: Add a section directive. Put braces around muscle
4065 * src/files.h (strsuffix, stringappend): Add declarations.
4066 (tab_extension): Add declaration.
4067 (short_base_name): Add declaration.
4069 * src/files.c (strsuffix, stringappend): No longer static. These
4070 functions are used in the skeleton parser.
4071 (tab_extension): New.
4072 (compute_base_names): Use the computations done in this function
4073 to guess if the generated parsers should have '.tab' in their
4075 (short_base_name): No longer static.
4077 * src/output.c (output_skeleton): New.
4078 (output): Disable call to output_master_parser, and give a try to
4079 a new skeleton handling system.
4080 (guards_output, actions_output): No longer static.
4081 (token_definitions_output, get_lines_number): No longer static.
4083 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
4085 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
4088 * src/parse-skel.y: New file.
4089 * src/scan-skel.l: New file.
4091 2001-12-29 Akim Demaille <akim@epita.fr>
4093 %name-prefix is broken.
4095 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
4096 Adjust all dependencies.
4097 * tests/headers.at (export YYLTYPE): Strengthen this test: use
4100 Renaming yylval but not yylloc is not consistent. Now we do.
4102 * src/bison.simple: Prefix yylloc if used.
4103 * doc/bison.texinfo (Decl Summary): Document that.
4105 2001-12-29 Akim Demaille <akim@epita.fr>
4107 * doc/bison.texinfo: Promote `%long-directive' over
4109 Remove all references to fixed-output-files, yacc is enough.
4111 2001-12-29 Akim Demaille <akim@epita.fr>
4113 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
4114 user prologue. These are defaults.
4115 * tests/actions.at (Mid-rule actions): Make sure the user can
4116 define YYDEBUG and YYERROR_VERBOSE.
4118 2001-12-29 Akim Demaille <akim@epita.fr>
4120 * src/output.c (header_output): Don't forget to export YYLTYPE and
4122 * tests/headers.at (export YYLTYPE): New, make sure it does.
4123 * tests/regression.at (%union and --defines, Invalid CPP headers):
4125 * tests/headers.at: here.
4127 2001-12-29 Akim Demaille <akim@epita.fr>
4129 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
4131 2001-12-29 Akim Demaille <akim@epita.fr>
4133 * tests/actions.at (Mid-rule actions): Output on a single line
4136 2001-12-29 Akim Demaille <akim@epita.fr>
4138 * doc/bison.texinfo: Formatting changes.
4140 2001-12-29 Akim Demaille <akim@epita.fr>
4142 Don't store the token defs in a muscle, just be ready to output it
4143 on command. Now possible via `symbols'. Fixes a memory leak.
4145 * src/output.c (token_definitions_output): New.
4146 (output_parser, header_output): Use it.
4147 * src/reader.c (symbols_save): Remove.
4149 2001-12-29 Akim Demaille <akim@epita.fr>
4151 * src/bison.simple: Do not provide a default for YYSTYPE and
4152 YYLTYPE before the user's prologue. Otherwise it's hardly... a
4155 2001-12-29 Akim Demaille <akim@epita.fr>
4157 Mid-rule actions are simply... ignored!
4159 * src/reader.c (readgram): Be sure to attach mid-rule actions to
4160 the empty-rule associated to the dummy symbol, not to the host
4162 * tests/actions.at (Mid-rule actions): New.
4164 2001-12-29 Akim Demaille <akim@epita.fr>
4168 * src/reader.c (reader): Free grammar.
4170 2001-12-29 Akim Demaille <akim@epita.fr>
4174 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
4175 since it allocates it for each state, although only one is needed.
4176 (allocate_storage): Do it here.
4178 2001-12-29 Akim Demaille <akim@epita.fr>
4180 * src/options.h, src/options.c (create_long_option_table): Rename
4182 (long_option_table_new): this, with a clearer prototype.
4183 (percent_table): Remove, unused,
4184 * src/getargs.c (getargs): Adjust.
4186 2001-12-29 Akim Demaille <akim@epita.fr>
4188 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
4189 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
4192 2001-12-29 Akim Demaille <akim@epita.fr>
4194 * src/lalr.c (build_relations): Rename `states' as `states1'.
4195 Sorry, I don't understand exactly what it is, no better name...
4197 2001-12-29 Akim Demaille <akim@epita.fr>
4199 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
4200 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
4201 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
4204 2001-12-29 Akim Demaille <akim@epita.fr>
4206 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
4209 2001-12-29 Akim Demaille <akim@epita.fr>
4211 * src/reader.c, src/reader.h (user_toknums): Remove.
4212 Adjust all users to use symbols[i]->user_token_number.
4214 2001-12-29 Akim Demaille <akim@epita.fr>
4216 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
4217 Adjust all users to use symbols[i]->prec or ->assoc.
4219 2001-12-29 Akim Demaille <akim@epita.fr>
4221 * src/reader.c, src/reader.h (tags): Remove.
4222 Adjust all users to use symbols[i]->tag.
4224 2001-12-29 Akim Demaille <akim@epita.fr>
4226 * src/gram.h, src/gram.c (symbols): New, similar to state_table
4228 * src/reader.c (packsymbols): Fill this table.
4230 * src/conflicts.c (resolve_sr_conflict): Adjust.
4231 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
4233 Use symbols[i]->tag instead of tags[i].
4235 2001-12-29 Akim Demaille <akim@epita.fr>
4237 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
4238 In addition, put a comment in there, to replace...
4239 * tests/regression.at (%union and C comments): Remove.
4241 2001-12-29 Akim Demaille <akim@epita.fr>
4243 * tests/regression.at (Web2c Actions): Blindly move the actual
4244 output as expected output. The contents *seem* right to me, but I
4245 can't pretend reading perfectly parser tables... Nonetheless, all
4246 the other tests pass correctly, the table look OK, even though the
4247 presence of `$axiom' is to be noted: AFAICS it is useless (but
4250 2001-12-29 Akim Demaille <akim@epita.fr>
4252 * src/reader.c (readgram): Don't add the rule 0 if there were no
4253 rules read. In other words, add it _after_ having performed
4254 grammar sanity checks.
4255 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
4257 2001-12-29 Akim Demaille <akim@epita.fr>
4259 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
4260 visible, and some states have now a different number.
4262 2001-12-29 Akim Demaille <akim@epita.fr>
4264 * src/reader.c (readgram): Bind the initial rule's lineno to that
4266 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
4267 (Solved SR Conflicts): Adjust rule 0's line number.
4269 2001-12-29 Akim Demaille <akim@epita.fr>
4271 Fix the `GAWK Grammar' failure.
4273 * src/LR0.c (final_state): Initialize to -1 so that we do compute
4274 the reductions of the first state which was mistakenly confused
4275 with the final state because precisely final_state was initialized
4277 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
4278 now noticed by Bison.
4279 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
4280 have a reduction on $default.
4282 2001-12-29 Akim Demaille <akim@epita.fr>
4284 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
4286 * src/closure.c (print_closure): Likewise.
4287 * src/derives.c (print_derives): Likewise.
4288 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
4291 2001-12-29 Akim Demaille <akim@epita.fr>
4293 * src/lalr.c (lookaheads_print): New.
4294 (lalr): Call it when --trace-flag.
4295 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
4298 2001-12-29 Akim Demaille <akim@epita.fr>
4300 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
4301 when walking through ritem, even via rule->rhs.
4302 * src/reduce.c (dump_grammar, useful_production, reduce_output)
4303 (useful_production, useless_nonterminals): Likewise.
4304 (reduce_grammar_tables): Likewise, plus update nritems.
4305 * src/nullable.c (set_nullable): Likewise.
4306 * src/lalr.c (build_relations): Likewise.
4307 * tests/sets.at (Nullable): Adjust.
4308 Fortunately, now, the $axiom is no longer nullable.
4310 2001-12-29 Akim Demaille <akim@epita.fr>
4312 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
4314 * src/gram.c (ritem_longest_rhs): Likewise.
4315 * src/reduce.c (nonterminals_reduce): Likewise.
4316 * src/print_graph.c (print_graph): Likewise.
4317 * src/output.c (output_rule_data): Likewise.
4318 * src/nullable.c (set_nullable): Likewise.
4320 2001-12-29 Akim Demaille <akim@epita.fr>
4322 * src/output.c: Comment changes.
4324 2001-12-27 Paul Eggert <eggert@twinsun.com>
4326 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
4327 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
4328 Sparc, as they were causing more porting problems than the
4329 (minor) performance improvement was worth.
4331 Also, catch up with 1.31's YYSTD.
4333 2001-12-27 Akim Demaille <akim@epita.fr>
4335 * src/output.c (output_gram): Rely on nritems, not the
4336 0-sentinel. See below.
4337 Use -1 as separator, not 0.
4338 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
4339 Rely on -1 as separator in yyrhs, instead of 0.
4340 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
4341 twice `Now at end of input', therefore there are two lines less to
4344 2001-12-27 Akim Demaille <akim@epita.fr>
4346 * tests/regression.at (Unresolved SR Conflicts):
4347 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
4350 2001-12-27 Akim Demaille <akim@epita.fr>
4352 * src/LR0.c (new_state): Recognize the final state by the fact it
4353 is reached by eoftoken.
4354 (insert_start_shifting_state, insert_eof_shifting_state)
4355 (insert_accepting_state, augment_automaton): Remove, since now
4356 these states are automatically computed from the initial state.
4357 (generate_states): Adjust.
4358 * src/print.c: When reporting a rule number to the user, substract
4359 1, so that the axiom rule is rule 0, and the first user rule is 1.
4360 * src/reduce.c: Likewise.
4361 * src/print_graph.c (print_core): For the time being, just as for
4362 the report, depend upon --trace-flags to dump the full set of
4364 * src/reader.c (readgram): Once the grammar read, insert the rule
4365 0: `$axiom: START-SYMBOL $'.
4366 * tests/set.at: Adjust: rule 0 is now displayed, and since the
4367 number of the states has changed (the final state is no longer
4368 necessarily the last), catch up.
4370 2001-12-27 Akim Demaille <akim@epita.fr>
4372 Try to make the use of the eoftoken valid. Given that its value
4373 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
4374 is used instead of > 0 where appropriate, (ii), depend upon nritems
4375 instead of the 0-sentinel.
4377 * src/gram.h, src/gram.c (nritems): New.
4378 Expected to be duplication of nitems, but for the time being...
4379 * src/reader.c (packgram): Assert nritems and nitems are equal.
4380 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
4381 * src/closure.c (print_closure, print_fderives): Likewise.
4382 * src/gram.c (ritem_print): Likewise.
4383 * src/print.c (print_core, print_grammar): Likewise.
4384 * src/print_graph.c: Likewise.
4386 2001-12-27 Akim Demaille <akim@epita.fr>
4388 * src/main.c (main): If there are complains after grammar
4389 reductions, then output the report anyway if requested, then die.
4390 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
4391 * src/reader.c (eoftoken): New.
4392 (parse_token_decl): If the token being defined has value `0', it
4394 (packsymbols): No longer hack `tags' to insert `$' by hand.
4395 Be sure to preserve the value of the eoftoken.
4396 (reader): Make sure eoftoken is defined.
4397 Initialize nsyms to 0: now eoftoken is created just like the others.
4398 * src/print.c (print_grammar): Don't special case the eof token.
4399 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
4400 lie anyway, albeit pleasant.
4401 * tests/calc.at: Exercise error messages with eoftoken.
4402 Change the grammar so that empty input is invalid.
4403 Adjust expectations.
4404 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
4406 2001-12-27 Akim Demaille <akim@epita.fr>
4408 * configure.in: Check the protos of strchr ans strspn.
4409 Replace strchr if needed.
4410 * src/system.h: Provide the protos of strchr, strspn and memchr if
4412 * lib/strchr.c: New.
4413 * src/reader.c (symbols_save): Use strchr.
4415 2001-12-27 Akim Demaille <akim@epita.fr>
4417 * src/print.c, src/print_graph.c (escape): New.
4418 Use it to quote the TAGS outputs.
4419 * src/print_graph.c (print_state): Now errors are in red, and
4420 reductions in green.
4421 Prefer high to wide: output the state number on a line of its own.
4423 2001-12-27 Akim Demaille <akim@epita.fr>
4425 * src/state.h, src/state.c (reductions_new): New.
4426 * src/LR0.c (set_state_table): Let all the states have a
4427 `reductions', even if reduced to 0.
4428 (save_reductions): Adjust.

4430 * src/print.c (print_reductions, print_actions): Adjust.

4433 2001-12-27 Akim Demaille <akim@epita.fr>
4435 * src/state.h, src/state.c (errs_new, errs_dup): New.
4436 * src/LR0.c (set_state_table): Let all the states have an errs,
4437 even if reduced to 0.
4438 * src/print.c (print_errs, print_reductions): Adjust.
4439 * src/output.c (output_actions, action_row): Adjust.
4440 * src/conflicts.c (resolve_sr_conflict): Adjust.
4442 2001-12-27 Akim Demaille <akim@epita.fr>
4444 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
4446 2001-12-27 Akim Demaille <akim@epita.fr>
4448 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
4449 * src/print.c: here.
4450 (lookaheadset, shiftset): New, used as additional storage by
4452 (print_results): Adjust.
4453 (print_shifts, print_gotos, print_errs): New, extracted from...
4454 (print_actions): here.
4455 * src/print_graph.c (print_actions): Remove dead code.
4457 2001-12-27 Akim Demaille <akim@epita.fr>
4459 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
4462 2001-12-27 Akim Demaille <akim@epita.fr>
4464 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
4465 (build_relations): Adjust.
4467 2001-12-27 Akim Demaille <akim@epita.fr>
4469 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
4472 2001-12-27 Akim Demaille <akim@epita.fr>
4474 * src/reader.c (packgram): Catch nitems overflows.
4476 2001-12-27 Akim Demaille <akim@epita.fr>
4478 * src/files.c, src/files.h (guard_obstack): Remove.
4479 * src/output.c (output): Adjust.
4480 * src/reader.c (parse_braces): New, factoring...
4481 (copy_action, copy_guard): these two which are renamed as...
4482 (parse_action, parse_guard): these.
4483 As a voluntary consequence, using braces around guards is now
4486 2001-12-27 Akim Demaille <akim@epita.fr>
4488 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
4489 * src/reader.c (symbol_list): `guard' and `guard_line' are new
4491 (symbol_list_new): Adjust.
4492 (copy_action): action_line is the first line, not the last.
4493 (copy_guard): Just as for actions, store the `action' only, not
4494 the switch/case/break flesh.
4495 Don't parse the user action that might follow the guard, let...
4496 (readgram): do it, i.e., now, there can be an action after a
4498 In other words the guard is just explicitly optional.
4500 * src/output.c (guards_output): New.
4501 (output_parser): Call it when needed.
4502 (output): Also free the guard and attrs obstacks.
4503 * src/files.c, src/files.h (obstack_save): Remove.
4504 (output_files): Remove.
4505 As a result, if one needs the former `.act' file, using an
4506 appropriate skeleton which requires actions and guards is now
4508 * src/main.c (main): Adjust.
4509 * tests/semantic.at: New.
4510 * tests/regression.at: Use `input.y' as input file name.
4511 Avoid 8+3 problems by requiring input.c when the test needs the

4516 * src/reader.c (symbol_list_new): Be sure to initialize all the
4519 2001-12-27 Akim Demaille <akim@epita.fr>
4521 All the hacks using a final pseudo state are now useless.
4523 * src/LR0.c (set_state_table): state_table holds exactly nstates.
4524 * src/lalr.c (nLA): New.
4525 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
4526 instead of lookaheadsp from the pseudo state (nstate + 1).
4528 2001-12-27 Akim Demaille <akim@epita.fr>
4530 * src/output.c (action_row, token_actions): Use a state_t instead
4531 of a integer, and nlookaheads instead of the following state's
4534 2001-12-27 Akim Demaille <akim@epita.fr>
4536 * src/conflicts.c (log_resolution, flush_shift)
4537 (resolve_sr_conflict, set_conflicts, solve_conflicts)
4538 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
4539 (conflicts_print, print_reductions): Use a state_t instead of an
4540 integer when referring to a state.
4541 As much as possible, depend upon nlookaheads, instead of the
4542 `lookaheadsp' member of the following state (since lookaheads of
4543 successive states are successive, the difference between state n + 1
4544 and n served as the number of lookaheads for state n).
4545 * src/lalr.c (add_lookback_edge): Likewise.
4546 * src/print.c (print_core, print_actions, print_state)
4547 (print_results): Likewise.
4548 * src/print_graph.c (print_core, print_actions, print_state)
4549 (print_graph): Likewise.
4550 * src/conflicts.h: Adjust.
4552 2001-12-27 Akim Demaille <akim@epita.fr>
4554 * src/bison.hairy: Formatting/comment changes.
4556 Remove `register' indications.
4557 Add plenty of `static'.
4559 2001-12-27 Akim Demaille <akim@epita.fr>
4561 * src/output.c (prepare): Drop the muscle `ntbase' which
4563 * src/bison.simple: Formatting/comment changes.
4564 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
4565 is an undocumented synonym.
4567 2001-12-22 Akim Demaille <akim@epita.fr>
4569 * src/output.c (output_table_data): Change the prototype to use
4570 `int' for array ranges: some invocations do pass an int, not a
4572 Reported by Wayne Green.
4574 2001-12-22 Akim Demaille <akim@epita.fr>
4576 Some actions of web2c.y are improperly triggered.
4577 Reported by Mike Castle.
4579 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
4580 * tests/regression.at (Web2c): Rename as...
4581 (Web2c Report): this.
4582 (Web2c Actions): New.
4584 2001-12-22 Akim Demaille <akim@epita.fr>
4586 Reductions in web2c.y are improperly reported.
4587 Reported by Mike Castle.
4589 * src/conflicts.c (print_reductions): Fix.
4590 * tests/regression.at (Web2c): New.
4592 2001-12-18 Akim Demaille <akim@epita.fr>
4594 Some host fail on `assert (!"foo")', which expands to
4595 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
4596 Reported by Nelson Beebee.
4598 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
4599 `#define it_succeeded 0' and `assert (it_succeeded)'.
4601 2001-12-17 Marc Autret <autret_m@epita.fr>
4603 * src/bison.simple: Don't hard code the skeleton line and filename.
4604 * src/output.c (output_parser): Rename 'line' as 'output_line'.
4605 New line counter 'skeleton_line' (skeleton-line muscle).
4607 2001-12-17 Paul Eggert <eggert@twinsun.com>
4609 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
4610 YYDEBUG must be defined to a nonzero value.
4612 * src/bison.simple (yytname): Do not assume that the user defines
4613 YYDEBUG to a properly parenthesized expression.
4615 2001-12-17 Akim Demaille <akim@epita.fr>
4617 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
4618 nlookaheads is a new member.
4620 * src/lalr.h (nlookaheads): Remove this orphan declaration.
4621 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
4624 2001-12-17 Akim Demaille <akim@epita.fr>
4626 * src/files.h, src/files.c (open_files, close_files): Remove.
4627 * src/main.c (main): Don't open/close files, nor invoke lex_free,
4629 * src/reader.c (reader): Do it.
4631 2001-12-17 Akim Demaille <akim@epita.fr>
4633 * src/conflicts.c (print_reductions): Formatting changes.
4635 2001-12-17 Akim Demaille <akim@epita.fr>
4637 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
4638 (flush_reduce): New.
4639 (resolve_sr_conflict): Adjust.
4641 2001-12-17 Akim Demaille <akim@epita.fr>
4643 * src/output.c (output_obstack): Be static and rename as...
4644 (format_obstack): this, to avoid any confusion with files.c's
4646 * src/reader.h (muscle_obstack): Move to...
4647 * src/output.h: here, since it's defined in output.c.
4649 2001-12-17 Akim Demaille <akim@epita.fr>
4651 * src/output.c (action_row, save_column, default_goto)
4652 (sort_actions, matching_state, pack_vector): Better variable
4655 2001-12-17 Akim Demaille <akim@epita.fr>
4657 * src/output.c: Various formatting changes.
4659 2001-12-17 Akim Demaille <akim@epita.fr>
4661 * src/files.c (output_files): Free the output_obstack.
4662 * src/main.c (main): Call print and print_graph conditionally.
4663 * src/print.c (print): Work unconditionally.
4664 * src/print_graph.c (print_graph): Work unconditionally.
4665 * src/conflicts.c (log_resolution): Output only if verbose_flag.
4667 2001-12-16 Marc Autret <autret_m@epita.fr>
4669 * src/output.c (actions_output): Fix. When we use %no-lines,
4670 there is one less line per action.
4672 2001-12-16 Marc Autret <autret_m@epita.fr>
4674 * src/bison.simple: Remove a useless #line directive.
4675 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
4676 * src/output.c (get_lines_number): New.
4677 (output_parser): Adjust, now takes care about the lines of a
4680 (actions_output): Computes the number of lines taken by actions.
4681 (output_master_parser): Insert new skeleton which is the name of
4682 the output parser file name.
4684 2001-12-15 Marc Autret <autret_m@epita.fr>
4686 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
4688 2001-12-15 Marc Autret <autret_m@epita.fr>
4690 * src/output.c (output_gram): Keep track of the hairy one.
4692 2001-12-15 Akim Demaille <akim@epita.fr>
4694 Make `make distcheck' work.
4696 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
4697 system.h which uses libgettext.h.
4699 2001-12-15 Akim Demaille <akim@epita.fr>
4701 * src/nullable.c (set_nullable): Useless rules must be skipped,
4702 otherwise, since we range over their symbols, we might look at a
4703 nonterminal which no longer ``exists'', i.e., it is not counted in
4704 `nvars', hence we overflow our arrays.
4706 2001-12-15 Akim Demaille <akim@epita.fr>
4708 The header can also be produced directly, without any obstack!
4711 * src/files.c, src/files.h (defines_obstack): Remove.
4712 (compute_header_macro): Global.
4713 (defines_obstack_save): Remove.
4714 * src/reader.c (parse_union_decl): No longer output to
4715 defines_obstack: its content can be found in the `stype' muscle
4717 (output_token_translations): Merge into...
4718 (symbols_output): this.
4720 (symbols_save): this.
4722 * src/output.c (header_output): New.
4725 2001-12-15 Akim Demaille <akim@epita.fr>
4727 * src/reader.c (parse_union_decl): Instead of handling two obstack
4728 simultaneously, use one to define the `stype' muscle, and use the
4729 value of the latter to fill defines_obstack.
4730 (copy_comment): Remove.
4731 (copy_comment2): Work for a single obstack.
4733 (copy_comment): this.
4735 2001-12-15 Akim Demaille <akim@epita.fr>
4737 * src/lex.c, src/lex.h (xgetc): No longer static.
4738 * src/reader.c (parse_union_decl): Revamp.
4740 2001-12-15 Akim Demaille <akim@epita.fr>
4742 Still making progress in separating Bison into (i) input, (ii)
4743 process, (iii) output: now we can directly output the parser file
4744 without using table_obstack at all.
4746 * src/files.c, src/files.h (table_obstack): Bye bye.
4747 (parser_file_name): New.
4748 * src/files.c (compute_output_file_names): Compute it.
4749 * src/output.c (actions_output, output_parser)
4750 (output_master_parser): To a file instead of an obstack.
4752 2001-12-15 Akim Demaille <akim@epita.fr>
4754 Attach actions to rules, instead of pre-outputting them to
4757 * src/gram.h (rule_t): action and action_line are new members.
4758 * src/reader.c (symbol_list): Likewise.
4759 (copy_action): Save the actions within the rule.
4760 (packgram): Save them in rule_table.
4761 * src/output.c (actions_output): New.
4762 (output_parser): Use it on `%%actions'.
4763 (output_rule_data): Don't free rule_table.
4765 (prepare): Don't save the `action' muscle.
4766 * src/bison.simple: s/%%action/%%actions/.
4768 2001-12-15 Akim Demaille <akim@epita.fr>
4770 * src/reader.c (copy_action): When --yacc, don't append a `;'
4771 to the user action: let it fail if lacking.
4772 Suggested by Arnold Robbins and Tom Tromey.
4774 2001-12-14 Akim Demaille <akim@epita.fr>
4776 * src/lex.c (literalchar): Simply return the char you decoded, non
4777 longer mess around with obstacks and int pointers.
4780 2001-12-14 Akim Demaille <akim@epita.fr>
4782 * src/lex.c (literalchar): Don't escape the special characters,
4783 just decode them, and keep them as char (before, eol was output as
4784 the 2 char string `\n' etc.).
4785 * src/output.c (output_rule_data): Use quotearg to output the
4788 2001-12-13 Paul Eggert <eggert@twinsun.com>
4790 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
4791 Do not infringe on the global user namespace when using C++.
4792 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
4793 All uses of `fprintf' and `stderr' changed.
4795 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
4797 2001-12-13 Akim Demaille <akim@epita.fr>
4799 The computation of nullable is broken: it doesn't handle empty
4802 * tests/torture.at (GNU AWK Grammar): New.
4803 * tests/sets.at (Nullable): New.
4804 * src/nullable.c (set_nullable): Instead of blindly looping over
4805 `ritems', loop over the rules, and then over their rhs's.
4807 Work around Autotest bugs.
4809 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
4810 frame, because Autotest understand lines starting with a `+' as
4811 traces from the shell. Then, they are not processed properly.
4812 Admittedly an Autotest bug, but we don't have time to wait for
4813 Autotest to catch up.
4814 * tests/regression.at (Broken Closure): Adjust to the new table
4817 * tests/sets.at: here.
4819 2001-12-13 Akim Demaille <akim@epita.fr>
4821 * src/closure.c (closure): Use nrules instead of playing tricks
4824 2001-12-13 Akim Demaille <akim@epita.fr>
4826 * src/print.c (print_actions): Output the handling of `$' as the
4827 traces do: shifting the token EOF. Before EOF was treated as a
4829 * tests/regression.at: Adjust some tests.
4830 * src/print_graph.c (print_core): Complete the set of items via
4831 closure. The next-to-final and final states are still unsatisfying,
4832 but that's to be addressed elsewhere.
4833 No longer output the rule numbers, but do output the state number.
4834 A single loop for the shifts + gotos is enough, but picked a
4835 distinct color for each.
4836 (print_graph): Initialize and finalize closure.
4838 2001-12-13 Akim Demaille <akim@epita.fr>
4840 * src/reader.c (readgram): Remove dead code, an strip useless
4842 (get_type): Remove, unused.
4844 2001-12-12 Akim Demaille <akim@epita.fr>
4846 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
4847 on that of lib/error.c.
4849 2001-12-12 Akim Demaille <akim@epita.fr>
4851 Some hosts don't like `/' in includes.
4853 * src/system.h: Include libgettext.h without qualifying the path.
4854 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
4857 2001-12-11 Marc Autret <autret_m@epita.fr>
4859 * src/output.c (output_parser): Remove useless muscle.
4861 2001-12-11 Marc Autret <autret_m@epita.fr>
4863 * src/bison.simple: Remove #line just before %%epilogue. It
4864 is now handled in ...
4865 * src/reader.c (read_additionnal_code): Add the output of a
4866 #line for the epilogue.
4868 2001-12-10 Marc Autret <autret_m@epita.fr>
4870 * src/reader.c (copy_definition): Re-use CPP-outed code which
4871 replace precedent remove.
4872 * src/bison.simple: Remove #line before %%prologue because
4873 %%input-line is wrong at this time.
4875 2001-12-10 Marc Autret <autret_m@epita.fr>
4877 * src/reader.c (symbols_output): Clean up.
4878 * src/output.c (output_gram, output): Clean up.
4880 2001-12-10 Akim Demaille <akim@epita.fr>
4882 * src/lalr.c (initialize_lookaheads): New. Extracted from...
4883 * src/LR0.c (set_state_table): here.
4884 * src/lalr.c (lalr): Call it.
4886 2001-12-10 Akim Demaille <akim@epita.fr>
4888 * src/state.h (shifts): Remove the `number' member: shifts are
4889 attached to state, hence no longer need to be labelled with a
4892 2001-12-10 Akim Demaille <akim@epita.fr>
4894 Now that states have a complete set of members, the linked list of
4895 shifts is useless: just fill directly the state's shifts member.
4897 * src/state.h (shifts): Remove the `next' member.
4898 * src/LR0.c (first_state, last_state): Remove.
4900 (augment_automaton): Don't look for the shifts that must be added
4901 a shift on EOF: it is those of the state we looked for! But now,
4902 since shifts are attached, it is no longer needed to looking
4903 merely by its id: its number.
4905 2001-12-10 Akim Demaille <akim@epita.fr>
4907 * src/LR0.c (augment_automaton): Better variable locality.
4908 Remove an impossible branch: if there is a state corresponding to
4909 the start symbol being shifted, then there is shift for the start
4910 symbol from the initial state.
4912 2001-12-10 Akim Demaille <akim@epita.fr>
4914 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
4915 only when appropriate: when insert_start_shifting_state' is not
4917 * tests/regression.at (Rule Line Numbers): Adjust.
4919 2001-12-10 Akim Demaille <akim@epita.fr>
4921 * src/LR0.c (augment_automaton): Now that all states have shifts,
4922 merge the two cases addition shifts to the initial state.
4924 2001-12-10 Akim Demaille <akim@epita.fr>
4926 * src/lalr.c (set_state_table): Move to...
4928 * src/lalr.c (lalr): Don't call it...
4929 * src/LR0.c (generate_states): do it.
4930 * src/LR0.h (first_state): Remove, only the table is used.
4932 2001-12-10 Akim Demaille <akim@epita.fr>
4934 * src/LR0.h (first_shift, first_reduction): Remove.
4935 * src/lalr.c: Don't use first_shift: find shifts through the
4938 2001-12-10 Akim Demaille <akim@epita.fr>
4940 * src/LR0.c: Attach shifts to states as soon as they are
4942 * src/lalr.c (set_state_table): Instead of assigning shifts to
4943 state, just assert that the mapping was properly done.
4945 2001-12-10 Akim Demaille <akim@epita.fr>
4947 * src/LR0.c (insert_start_shift): Rename as...
4948 (insert_start_shifting_state): this.
4949 (insert_eof_shifting_state, insert_accepting_state): New.
4950 (augment_automaton): Adjust.
4951 Better locality of the variables.
4952 When looking if the start_symbol is shifted from the initial
4953 state, using `while (... symbol != start_symbol ...)' sounds
4954 better than `while (... symbol < start_symbol ...)': If fail
4955 to see how the order between symbols could be relevant!
4957 2001-12-10 Akim Demaille <akim@epita.fr>
4959 * src/getargs.h: Don't declare `spec_name_prefix' and
4960 `spec_file_prefix', declared by src/files.h.
4961 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
4962 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
4963 * src/output.c (prepare): Adjust.
4964 * src/reader.c (symbols_output): Likewise.
4965 * src/vmsgetargs.c: Vaguely adjust, but who cares?
4967 2001-12-10 Akim Demaille <akim@epita.fr>
4969 * src/muscle_tab.c (muscle_init): NULL is a better default than
4972 2001-12-10 Akim Demaille <akim@epita.fr>
4974 * src/reader.c (reader): Calling symbols_output once is enough.
4976 2001-12-10 Akim Demaille <akim@epita.fr>
4978 Now that states have a complete set of members, the linked list of
4979 reductions is useless: just fill directly the state's reductions
4982 * src/state.h (struct reductions): Remove member `number' and
4984 * src/LR0.c (first_reduction, last_reduction): Remove.
4985 (save_reductions): Don't link the new reductions, store them in
4987 * src/lalr.c (set_state_table): No need to attach reductions to
4988 states, it's already done.
4989 * src/output.c (output_actions): No longer free the shifts, then
4990 the reductions, then the states: free all the states and their
4993 2001-12-10 Akim Demaille <akim@epita.fr>
4995 * src/options.c (OPTN, DRTV, BOTH): New.
4996 (option_table): Use them.
4998 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
4999 the job of system.h.
5000 * src/options.c: Don't include stdio.h and xalloc.h for the same
5003 2001-12-10 Akim Demaille <akim@epita.fr>
5005 * src/output.c (output, prepare): Make sure the values of the
5006 muscles `action' and `prologue' are 0-terminated.
5008 2001-12-10 Akim Demaille <akim@epita.fr>
5010 Clean up GCC warnings.
5012 * src/reader.c (copy_action): `buf' is not used.
5013 (parse_skel_decl): Be static.
5014 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
5015 * src/options.h (create_long_option_table): Have a real prototype.
5016 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
5017 (hash_delete_at): Return const void *.
5018 Adjust casts to preserve the const.
5020 2001-12-10 Akim Demaille <akim@epita.fr>
5022 * configure.in: Require 2.52g.
5023 M4 is not needed, but AUTOM4TE is.
5025 * tests/Makefile.am: Adjust.
5027 2001-12-10 Akim Demaille <akim@epita.fr>
5029 One structure for states is enough, even though theoretically
5030 there are LR(0) states and LALR(1) states.
5032 * src/lalr.h (state_t): Remove.
5033 (state_table): Be state_t **, not state_t *.
5034 * src/state.h (core, CORE_ALLOC): Rename as...
5035 (state_t, STATE_ALLOC): this.
5036 Add the LALR(1) members: shifts, reductions, errs.
5037 * src/LR0.c (state_table): Rename as...
5038 (state_hash): this, to avoid name clashes with the global
5040 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
5041 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
5043 2001-12-10 Akim Demaille <akim@epita.fr>
5045 Bison dumps core on bash.y.
5046 Reported by Pascal Bart.
5048 * src/warshall.c (bitmatrix_print): New.
5050 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),

5070 * src/reduce.c (reduce_grammar_tables): No longer disable the
5071 removal of useless rules via CPP but via `if (0)', so that the
5072 compiler still check the code is valid.
5073 For instance, it should have noticed `rline' no longer exists: use
5074 the `line' member of rule_t.
5075 * src/gram.c (dummy, rline): Remove, unused.
5077 2001-12-05 Akim Demaille <akim@epita.fr>
5079 * src/output.c (pack_vector): Use assert, not berror.
5080 * src/main.c (berror): Remove, unused.
5082 2001-12-05 Akim Demaille <akim@epita.fr>
5084 New experimental feature: if --verbose --trace output all the
5085 items of a state, not only its kernel.
5087 * src/print.c (print_core): If `trace_flag', then invoke closure
5088 before outputting the items of the state (print_core is no longer
5089 a correct name them).

5101 (closure): Use it for printing input and output.
5103 2001-12-05 Akim Demaille <akim@epita.fr>
5105 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
5106 indexed by nonterminals.
5108 2001-12-05 Akim Demaille <akim@epita.fr>
5110 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

5130 locality, BITISSET, RESETBIT etc.
5132 2001-12-05 Akim Demaille <akim@epita.fr>
5134 Pessimize the code to simplify it: from now on, all the states
5135 have a valid SHIFTS, which NSHIFTS is possibly 0.
5137 * src/LR0.c (shifts_new): Be global and move to..
5138 * src/state.c, src/state.h: here.
5139 * src/conflicts, src/lalr.c, src/output.c, src/print.c,

5201 Use arrays instead of pointers.
5203 2001-12-05 Akim Demaille <akim@epita.fr>
5205 * src/lalr.c (maxrhs): Move to...
5206 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
5207 * src/lalr.c (build_relations): Adjust.
5209 2001-12-05 Akim Demaille <akim@epita.fr>
5211 * src/lalr.c (transpose): Free the memory allocated to the
5212 argument, as it is replaced by the results by the unique caller.
5213 (build_relations): Merely invoke transpose: it handles the memory
5215 Improve variable locality.
5216 Avoid variables used as mere abbreviations.
5217 (compute_lookaheads): Use arrays instead of pointers.
5219 2001-12-05 Akim Demaille <akim@epita.fr>

5235 2001-12-05 Akim Demaille <akim@epita.fr>
5237 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
5238 the handling of squeue.
5239 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
5241 2001-12-05 Akim Demaille <akim@epita.fr>
5243 Because useless nonterminals are now kept alive (instead of being
5244 `destroyed'), we now sometimes examine them, and store information
5245 related to them. Hence we need to know their number, and adjust
5248 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
5250 * src/LR0.c (allocate_itemsets): The memory allocated to
5251 `symbol_count' was used for two different purpose: once to count
5252 the number of occurrences of each symbol, and later reassigned to
5253 `shift_symbol', containing the symbol that can be shifted from a
5255 Deobfuscate, i.e., allocate, use and free `symbol_count' here
5257 (new_itemsets): Allocate `shift_symbol' here.
5258 (allocate_itemsets): symbol_count includes useless nonterminals.
5260 (free_storage): Use `free', not `XFREE', for pointers that cannot
5263 2001-12-05 Akim Demaille <akim@epita.fr>
5265 * src/nullable.c (set_nullable): Deobfuscate the handling of
5267 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
5269 2001-12-05 Akim Demaille <akim@epita.fr>
5271 * src/gram.c, src/gram.h (ritem_print): New.
5272 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
5273 (This useless function was defined only to work around VMS linkers
5274 that can't handle compilation units with variables only).
5275 * src/reduce.c (dump_grammar): Use it to trace the construction of
5278 2001-12-04 Paul Eggert <eggert@twinsun.com>
5280 * src/bison.simple (union yyalloc): Change member names
5281 to be the same as the stack names.
5282 (yyparse): yyptr is now union yyalloc *, not char *.
5283 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
5284 and may generate better code on some machines.
5285 (yystpcpy): Use prototype if __STDC__ is defined, not just
5286 if __cplusplus is defined.
5288 2001-11-30 Akim Demaille <akim@epita.fr>
5290 * configure.in (WARNING_CFLAGS): Add -Werror when possible.

5294 Include WARNING_CFLAGS here.
5295 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared

5303 (SIZE_MAX, UINT_MAX): New macros.
5304 (quotearg_n_options): Abort if N is negative.
5305 Avoid overflow check on hosts where size_t is 64 bits and int
5306 is 32 bits, as overflow is impossible there.
5307 Fix off-by-one typo that caused unnecessary reallocation.
5309 2001-11-29 Paul Eggert <eggert@twinsun.com>
5311 Name space cleanup in generated parser.
5313 * doc/bison.texinfo (Bison Parser): Discuss system headers
5314 and their effect on the user name space.
5317 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,

5322 on user names when possible.
5324 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
5325 Simplify test for whather <alloca.h> exists.
5327 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
5329 (<stdio.h>): Include if YYDEBUG.
5331 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
5332 ! defined (yyoverflow) && ! defined (yymemcpy).
5334 (yymemcpy, yyparse): Rename local variables as needed so that
5335 they all begin with 'yy'.
5337 (yystrlen, yystpcpy): New functions.
5339 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
5342 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
5343 instead of relying on string.h functions. Use YYSTACK_ALLOC
5344 and YYSTACK_FREE instead of malloc and free.
5346 2001-11-30 Akim Demaille <akim@epita.fr>
5348 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
5349 before their first uses.

5358 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
5359 if body instead of `;' to pacify GCC's warnings.
5361 2001-11-30 Akim Demaille <akim@epita.fr>
5363 Instead of mapping the LHS of unused rules to -1, keep the LHS
5364 valid, but flag the rules as invalid.
5366 * src/gram.h (rule_t): `useful' is a new member.
5367 * src/print.c (print_grammar): Adjust.
5368 * src/derives.c (set_derives): Likewise.
5369 * src/reader.c (packgram, reduce_output): Likewise.

5398 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
5400 (union yyalloc): New type.
5401 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
5402 an arbitrary restriction on hosts where size_t is wider than int.
5404 (yyparse): Don't dump core if alloca or malloc fails; instead, report
5405 a parser stack overflow. Allocate just one block of memory for all
5406 three stacks, instead of allocating three blocks; this typically is
5407 faster and reduces fragmentation.
5409 Do not limit the number of items in the stack to a value that fits
5410 in 'int', as this is an arbitrary limit on hosts with 64-bit
5411 size_t and 32-bit int.
5413 2001-11-29 Marc Autret <autret_m@epita.fr>
5415 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

5466 2001-11-28 Akim Demaille <akim@epita.fr>
5468 * src/closure.c (closure): Instead of looping over word in array
5469 then bits in words, loop over bits in array.
5471 2001-11-28 Akim Demaille <akim@epita.fr>
5473 * src/closure.c (closure): No longer optimize the special case
5474 where all the bits of `ruleset[r]' are set to 0, to make the code

5498 2001-11-27 Paul Eggert <eggert@twinsun.com>
5500 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to

7222 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
7223 New, from fileutils 4.0.37.
7224 * configure.in: Require Autoconf 2.49c. I took some time before
7225 making this decision. This is the only way out for portability
7226 issues in Bison, it would mean way too much duplicate effort to
7227 import in Bison features implemented in 2.49c since 2.13.
7228 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
7230 2001-02-02 Akim Demaille <akim@epita.fr>
7232 * lib/malloc.c, lib/realloc.c: New, from the fileutils 4.0.37.
7233 * lib/xalloc.h, lib/xmalloc.c: Update.
7235 2001-01-19 Akim Demaille <akim@epita.fr>
7237 Get rid of the ad hoc handling of token_buffer in the scanner: use
7240 * src/lex.c (token_obstack): New.
7241 (init_lex): Initialize it. No longer call...
7242 (grow_token_buffer): this. Remove it.
7243 Adjust all the places which used it to use the obstack.
7245 2001-01-19 Akim Demaille <akim@epita.fr>
7247 * src/lex.h: Rename all the tokens:
7248 s/\bENDFILE\b/tok_eof/g;
7249 s/\bIDENTIFIER\b/tok_identifier/g;
7251 Let them be enums, not #define, to ease debugging.
7252 Adjust all the code.

7256 * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
7257 * src/lex.c (maxtoken, grow_token_buffer): Static.
7259 2001-01-18 Akim Demaille <akim@epita.fr>
7261 Since we now use obstacks, more % directives can be enabled.
7263 * src/lex.c (percent_table): Also accept `%yacc',
7264 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
7266 Handle the actions for `%semantic_parser' and `%pure_parser' here,
7267 instead of returning a token.
7268 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
7269 * src/reader.c (read_declarations): Adjust.
7270 * src/files.c (open_files): Don't call `compute_base_names', don't
7271 compute `attrsfile' since they depend upon data which might be
7272 *in* the input file now.
7273 (output_files): Do it here.
7274 * src/output.c (output_headers): Document the fact that this patch
7275 introduces a guaranteed SEGV for semantic parsers.
7276 * doc/bison.texinfo: Document them.
7277 * tests/suite.at: Exercise these %options.
7279 2000-12-20 Akim Demaille <akim@epita.fr>

7293 * src/files.c (open_files): Fix the computation of short_base_name

7298 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

7302 2000-12-20 Akim Demaille <akim@epita.fr>
7304 * src/files.c (open_files): Actually the `.output' file is based
7305 on the short_base_name, not base_name.
7306 * tests/suite.at (Checking output file names): Adjust.
7308 2000-12-20 Akim Demaille <akim@epita.fr>

7329 Adjust dependencies.
7331 2000-12-19 Akim Demaille <akim@epita.fr>
7333 * src/files.c (strsuffix): New.
7334 (stringappend): Be just like strcat but allocate.

7348 * src/bison.hairy: Likewise.
7350 2000-12-19 Akim Demaille <akim@epita.fr>
7352 * src/output.c (output_parser): Compute the `#line' lines when
7354 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
7355 Suggested by Hans Aberg.
7357 2000-12-19 Akim Demaille <akim@epita.fr>
7359 Let the handling of the skeleton files be local to the procedures

7374 * src/file.h (BISON_SIMPLE, BISON_HAIRY): Move from here...

7377 2000-12-19 Akim Demaille <akim@epita.fr>
7379 * src/files.c (open_files): Yipee! We no longer need all the code
7380 looking for `/tmp' since we have no tmp file.
7382 2000-12-19 Akim Demaille <akim@epita.fr>
7384 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

7411 * lib/obstack.h: Formatting changes.
7412 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
7413 prevents type checking.
7414 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
7415 cast the value to (void *): assigning a `foo *' to a `void *'
7417 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
7418 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

7423 * tests/Makefile.am (suite.m4, regression.m4, calc.m4): Rename
7425 (suite.m4, regression.m4, calc.m4): these.
7426 * tests/atgeneral.m4: Update from CVS Autoconf.
7428 2000-11-17 Akim Demaille <akim@epita.fr>
7430 * tests/regression.m4 (%union and --defines): New test,
7431 demonstrating a current bug in the obstack implementation.
7433 2000-11-17 Akim Demaille <akim@epita.fr>
7435 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
7437 Use them to declare the variables which are global or local to

7442 * acconfig.h: Remove, no longer used.
7444 2000-11-07 Akim Demaille <akim@epita.fr>
7446 * src: s/Copyright (C)/Copyright/g.
7448 2000-11-07 Akim Demaille <akim@epita.fr>
7450 * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just
7452 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
7454 2000-11-07 Akim Demaille <akim@epita.fr>
7456 * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
7457 Merge in a single CPP if/else.
7459 2000-11-07 Akim Demaille <akim@epita.fr>
7461 * src/output.c (output): Remove useless variables.
7462 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
7463 argument `data' for consistency with the prototypes.
7465 (obstack_copy, obstack_copy0): Rename the second argument as
7466 `address' for consistency. Qualify it `const'.
7467 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
7468 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
7469 `const' their input argument (`data' or `address').
7470 Adjust the corresponding macros to include `const' in casts.
7472 2000-11-03 Akim Demaille <akim@epita.fr>
7474 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
7475 s/PFILE1/BISON_HAIRY/.
7476 Adjust dependencies.
7478 2000-11-03 Akim Demaille <akim@epita.fr>
7480 For some reason, this was not applied.
7482 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
7483 `unlink': it's no longer used.
7485 2000-11-03 Akim Demaille <akim@epita.fr>
7487 * src/files.c (skeleton_find): New function, eved out of...
7488 (open_files, open_extra_files): here.
7490 2000-11-03 Akim Demaille <akim@epita.fr>
7494 * src/files.c (obstack_save): New function.
7495 (done): Rename as...
7496 (output_files): this.
7498 * src/main.c (main): Don't use `atexit' to register `done', since
7499 it no longer has to remove tmp files, just call `output_files'
7500 when there are no errors.
7502 2000-11-02 Akim Demaille <akim@epita.fr>
7504 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
7505 `unlink': it's no longer used.
7506 * src/files.h: Formatting changes.
7508 2000-11-02 Akim Demaille <akim@epita.fr>

7524 Change each use of `fattrs' into a use of `attrs_obstack'.
7526 * src/reader.c (copy_at): Typo: s/yylloc/yyloc/.
7527 * src/files.c (fattrs): Remove.
7528 (attrs_obstack): New.
7529 Adjust all dependencies.
7530 (done): If SEMANTIC_PARSER, dump attrs_obstack into attrsfile.
7532 2000-11-01 Akim Demaille <akim@epita.fr>
7535 Change each use of `faction' into a use of `action_obstack'.
7537 * lib/obstack.h, lib/obstack.c: New files.
7538 * src/files.c (faction): Remove.
7539 (action_obstack): New.
7540 Adjust all dependencies.
7542 2000-10-20 Akim Demaille <akim@epita.fr>

7567 * src/reader.c (copy_dollar): Likewise.
7569 2000-10-16 Akim Demaille <akim@epita.fr>
7571 * src/reader.c (copy_comment2): Expect the input stream to be on
7572 the `/' which is suspected to open a comment, instead of being
7573 called after `//' or `/*' was read.
7574 (copy_comment, copy_definition, parse_union_decl, copy_action)
7575 (copy_guard): Adjust.
7577 2000-10-16 Akim Demaille <akim@epita.fr>
7579 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
7580 `read_signed_integer'.

7584 * src/reader.c (copy_dollar): New function.
7585 (copy_guard, copy_action): Use it.
7587 2000-10-16 Akim Demaille <akim@epita.fr>
7589 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
7590 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
7591 New files, from Fileutils 4.0.27.
7592 * src/main.c (printable_version): Remove.
7593 * src/lex.c, src/reader.c: Use `quote'.
7595 2000-10-04 Akim Demaille <akim@epita.fr>
7597 * lib/error.c, lib/error.h: New files, needed by xmalloc.c.
7599 2000-10-04 Akim Demaille <akim@epita.fr>
7601 * doc/bison.texinfo: Various typos spotted by Neil Booth.
7603 2000-10-04 Akim Demaille <akim@epita.fr>
7605 When a literal string is used to define two different tokens,
7606 `bison -v' segfaults.
7607 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
7609 * tests/regression.m4: New file.
7610 Include the core of the sample provided by Piotr Gackiewicz.
7611 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
7614 2000-10-04 Akim Demaille <akim@epita.fr>
7616 * src/reader.c (parse_expect_decl): Keep `count' within the size
7620 2000-10-02 Paul Eggert <eggert@twinsun.com>
7622 * bison.s1 (yyparse): Assign the default value
7623 unconditionally, to avoid a GCC warning and make the parser a
7626 2000-10-02 Akim Demaille <akim@epita.fr>
7628 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
7631 2000-10-02 Akim Demaille <akim@epita.fr>
7633 * src/derives.c, src/print.c, src/reduce.c: To ease the
7634 translation, move some `\n' out of the translated strings.
7636 2000-10-02 Akim Demaille <akim@epita.fr>
7638 The location tracking mechanism is precious for parse error
7639 messages. Nevertheless, it is enabled only when `@n' is used in
7640 the grammar, which is a different issue (you can use it in error
7641 message, but not in the grammar per se). Therefore, there should
7642 be another means to enable it.
7644 * src/getargs.c (getargs): Support `--locations'.
7646 * src/getargs.h (locationsflag): Export it.
7647 * src/lex.c (percent_table): Support `%locations'.
7648 * src/reader.c (yylsp_needed): Remove this variable, now replaced
7649 with `locationsflag'.
7650 * doc/bison.texinfo: Document `--locations' and `%locations'.
7652 * tests/calc.m4: Test it.
7654 For regularity of the names, replace each
7655 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
7656 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
7657 In addition replace each `flag' with `_flag'.
7659 2000-10-02 Akim Demaille <akim@epita.fr>
7661 Also test parse error messages, including with YYERROR_VERBOSE.
7663 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
7665 Use it to check the computations.
7666 Use it to check `nonassoc' is honored.
7667 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
7668 `--yyerror-verbose'.
7669 (_AT_CHECK_CALC): Adjust to this option.
7670 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
7672 2000-10-02 Akim Demaille <akim@epita.fr>
7674 Test also `--verbose', `--defines' and `--name-prefix'. Testing
7675 the latter demonstrates a flaw in the handling of non debugging
7676 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
7677 was used in order to simplify:
7693 unfortunately this leads to a CPP conflict when
7694 `--name-prefix=foo' is used since it produces `#define yydebug
7697 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
7698 (YYDPRINTF): New macro.
7700 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
7702 Also test `--verbose', `--defines' and `--name-prefix'.
7704 2000-10-02 Akim Demaille <akim@epita.fr>
7706 Improve the readability of the produced parsers.
7708 * src/bison.s1: Formatting changes.
7709 Improve the comment related to the `$' mark.
7710 (yydefault): Don't fall through to `yyresume': `goto' there.
7711 * src/output.c (output_parser): When the `$' is met, skip the end
7713 New variable, `number_of_dollar_signs', to check there's exactly
7714 one `$' in the parser skeleton.
7716 2000-10-02 Akim Demaille <akim@epita.fr>
7718 * lib/xstrdup.c: New file, from the fileutils.
7719 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
7720 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
7721 instead of strlen + xmalloc + strcpy.
7722 * src/symtab.c (copys): Remove, use xstrdup instead.
7724 2000-10-02 Akim Demaille <akim@epita.fr>
7726 * src/gram.h (associativity): New enum type which replaces the
7727 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
7728 `right_assoc', `left_assoc' and `non_assoc'.
7729 Adjust all dependencies.
7730 * src/reader.c: Formatting changes.
7731 (LTYPESTR): Don't define it, use it as a literal in
7732 `reader_output_yylsp'.
7733 * src/symtab.h (symbol_class): New enum type which replaces the
7734 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
7735 `sunknown', `stoken and `snterm'.
7737 2000-10-02 Akim Demaille <akim@epita.fr>
7739 * src/getargs.c (fixed_outfiles): Rename as...
7740 (yaccflag): for consistency and accuracy.
7741 Adjust dependencies.
7743 2000-10-02 Akim Demaille <akim@epita.fr>
7745 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
7746 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
7747 difficult and introduced a lot of core dump. It turns out that
7748 Bison used an implementation of `xmalloc' based on `calloc', and
7749 at various places it does depend upon the initialization to 0. I
7750 have not tried to isolate the pertinent places, and all the former
7751 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
7752 someone should address this issue.
7754 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
7755 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
7757 Adjust dependencies.
7758 * src/warshall.h: New file.
7761 2000-10-02 Akim Demaille <akim@epita.fr>
7763 Various anti-`extern in *.c' changes.
7765 * src/system.h: Include `assert.h'.
7767 2000-10-02 Akim Demaille <akim@epita.fr>

8889 way to specify the flags -n, -l, and -r. Also added hooks for
8890 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
8891 major changes to files.c.
8892 (lex) Retain in the incoming stream a character following
