1 2001-12-27 Akim Demaille <akim@epita.fr>
3 * src/output.c (output_gram): Rely on nritems, not the
5 Use -1 as separator, not 0.
6 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
7 Rely on -1 as separator in yyrhs, instead of 0.
8 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
9 twice `Now at end of input', therefore there are two lines less to
12 2001-12-27 Akim Demaille <akim@epita.fr>
14 * tests/regression.at (Unresolved SR Conflicts):
15 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
18 2001-12-27 Akim Demaille <akim@epita.fr>
20 * src/LR0.c (new_state): Recognize the final state by the fact it
21 is reached by eoftoken.
22 (insert_start_shifting_state, insert_eof_shifting_state)
23 (insert_accepting_state, augment_automaton): Remove, since now
24 these states are automatically computed from the initial state.
25 (generate_states): Adjust.
26 * src/print.c: When reporting a rule number to the user, substract
27 1, so that the axiom rule is rule 0, and the first user rule is 1.
28 * src/reduce.c: Likewise.
29 * src/print_graph.c (print_core): For the time being, just as for
30 the report, depend upon --trace-flags to dump the full set of
32 * src/reader.c (readgram): Once the grammar read, insert the rule
33 0: `$axiom: START-SYMBOL $'.
34 * tests/set.at: Adjust: rule 0 is now displayed, and since the
35 number of the states has changed (the final state is no longer
36 necessarily the last), catch up.
38 2001-12-27 Akim Demaille <akim@epita.fr>
40 Try to make the use of the eoftoken valid. Given that its value
41 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
42 is used instead of > 0 where appropriate, (ii), depend upon nritems
43 instead of the 0-sentinel.
45 * src/gram.h, src/gram.c (nritems): New.
46 Expected to be duplication of nitems, but for the time being...
47 * src/reader.c (packgram): Assert nritems and nitems are equal.
48 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
49 * src/closure.c (print_closure, print_fderives): Likewise.
50 * src/gram.c (ritem_print): Likewise.
51 * src/print.c (print_core, print_grammar): Likewise.

54 2001-12-27 Akim Demaille <akim@epita.fr>
56 * src/main.c (main): If there are complains after grammar
57 reductions, then output the report anyway if requested, then die.
58 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
59 * src/reader.c (eoftoken): New.
60 (parse_token_decl): If the token being defined has value `0', it
62 (packsymbols): No longer hack `tags' to insert `$' by hand.
63 Be sure to preserve the value of the eoftoken.
64 (reader): Make sure eoftoken is defined.
65 Initialize nsyms to 0: now eoftoken is created just like the others.
66 * src/print.c (print_grammar): Don't special case the eof token.
67 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
68 lie anyway, albeit pleasant.
69 * tests/calc.at: Exercise error messages with eoftoken.
70 Change the grammar so that empty input is invalid.
72 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
74 2001-12-27 Akim Demaille <akim@epita.fr>
76 * configure.in: Check the protos of strchr ans strspn.
77 Replace strchr if needed.
78 * src/system.h: Provide the protos of strchr, strspn and memchr if
81 * src/reader.c (symbols_save): Use strchr.
83 2001-12-27 Akim Demaille <akim@epita.fr>
85 * src/print.c, src/print_graph.c (escape): New.
86 Use it to quote the TAGS outputs.
87 * src/print_graph.c (print_state): Now errors are in red, and
89 Prefer high to wide: output the state number on a line of its own.
91 2001-12-27 Akim Demaille <akim@epita.fr>
93 * src/state.h, src/state.c (reductions_new): New.
94 * src/LR0.c (set_state_table): Let all the states have a
95 `reductions', even if reduced to 0.
96 (save_reductions): Adjust.
97 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
98 * src/print.c (print_reductions, print_actions): Adjust.
99 * src/output.c (action_row): Adjust.
101 2001-12-27 Akim Demaille <akim@epita.fr>
103 * src/state.h, src/state.c (errs_new, errs_dup): New.
104 * src/LR0.c (set_state_table): Let all the states have an errs,
105 even if reduced to 0.
106 * src/print.c (print_errs, print_reductions): Adjust.
107 * src/output.c (output_actions, action_row): Adjust.
108 * src/conflicts.c (resolve_sr_conflict): Adjust.
110 2001-12-27 Akim Demaille <akim@epita.fr>

114 2001-12-27 Akim Demaille <akim@epita.fr>
116 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
118 (lookaheadset, shiftset): New, used as additional storage by
120 (print_results): Adjust.
121 (print_shifts, print_gotos, print_errs): New, extracted from...
122 (print_actions): here.
123 * src/print_graph.c (print_actions): Remove dead code.
125 2001-12-27 Akim Demaille <akim@epita.fr>
127 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
130 2001-12-27 Akim Demaille <akim@epita.fr>
132 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
133 (build_relations): Adjust.
135 2001-12-27 Akim Demaille <akim@epita.fr>
137 * src/lalr.c (set_goto_map): Remove a wrong but benign loop

146 * src/files.c, src/files.h (guard_obstack): Remove.
147 * src/output.c (output): Adjust.
148 * src/reader.c (parse_braces): New, factoring...
149 (copy_action, copy_guard): these two which are renamed as...
150 (parse_action, parse_guard): these.
151 As a voluntary consequence, using braces around guards is now
154 2001-12-27 Akim Demaille <akim@epita.fr>
156 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
157 * src/reader.c (symbol_list): `guard' and `guard_line' are new
159 (symbol_list_new): Adjust.
160 (copy_action): action_line is the first line, not the last.
161 (copy_guard): Just as for actions, store the `action' only, not
162 the switch/case/break flesh.
163 Don't parse the user action that might follow the guard, let...
164 (readgram): do it, i.e., now, there can be an action after a
166 In other words the guard is just explicitly optional.
168 * src/output.c (guards_output): New.
169 (output_parser): Call it when needed.
170 (output): Also free the guard and attrs obstacks.
171 * src/files.c, src/files.h (obstack_save): Remove.
172 (output_files): Remove.
173 As a result, if one needs the former `.act' file, using an
174 appropriate skeleton which requires actions and guards is now
176 * src/main.c (main): Adjust.
177 * tests/semantic.at: New.
178 * tests/regression.at: Use `input.y' as input file name.
179 Avoid 8+3 problems by requiring input.c when the test needs the

189 All the hacks using a final pseudo state are now useless.
191 * src/LR0.c (set_state_table): state_table holds exactly nstates.
192 * src/lalr.c (nLA): New.
193 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
194 instead of lookaheadsp from the pseudo state (nstate + 1).
196 2001-12-27 Akim Demaille <akim@epita.fr>
198 * src/output.c (action_row, token_actions): Use a state_t instead
199 of a integer, and nlookaheads instead of the following state's

205 (resolve_sr_conflict, set_conflicts, solve_conflicts)
206 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
207 (conflicts_print, print_reductions): Use a state_t instead of an
208 integer when referring to a state.
209 As much as possible, depend upon nlookaheads, instead of the
210 `lookaheadsp' member of the following state (since lookaheads of
211 successive states are successive, the difference between state n + 1
212 and n served as the number of lookaheads for state n).
213 * src/lalr.c (add_lookback_edge): Likewise.
214 * src/print.c (print_core, print_actions, print_state)
215 (print_results): Likewise.
216 * src/print_graph.c (print_core, print_actions, print_state)

222 * src/bison.hairy: Formatting/comment changes.
224 Remove `register' indications.
225 Add plenty of `static'.
227 2001-12-27 Akim Demaille <akim@epita.fr>
229 * src/output.c (prepare): Drop the muscle `ntbase' which
231 * src/bison.simple: Formatting/comment changes.
232 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
233 is an undocumented synonym.
235 2001-12-22 Akim Demaille <akim@epita.fr>
237 * src/output.c (output_table_data): Change the prototype to use
238 `int' for array ranges: some invocations do pass an int, not a
240 Reported by Wayne Green.
242 2001-12-22 Akim Demaille <akim@epita.fr>
244 Some actions of web2c.y are improperly triggered.

260 2001-12-18 Akim Demaille <akim@epita.fr>
262 Some host fail on `assert (!"foo")', which expands to
263 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
264 Reported by Nelson Beebee.
266 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
267 `#define it_succeeded 0' and `assert (it_succeeded)'.
269 2001-12-17 Marc Autret <autret_m@epita.fr>
271 * src/bison.simple: Don't hard code the skeleton line and filename.
272 * src/output.c (output_parser): Rename 'line' as 'output_line'.
273 New line counter 'skeleton_line' (skeleton-line muscle).
275 2001-12-17 Paul Eggert <eggert@twinsun.com>
277 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
278 YYDEBUG must be defined to a nonzero value.
280 * src/bison.simple (yytname): Do not assume that the user defines
281 YYDEBUG to a properly parenthesized expression.
283 2001-12-17 Akim Demaille <akim@epita.fr>
285 * src/state.h (state_t): Rename lookaheads as lookaheadsp.

299 2001-12-17 Akim Demaille <akim@epita.fr>
301 * src/conflicts.c (print_reductions): Formatting changes.
303 2001-12-17 Akim Demaille <akim@epita.fr>
305 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
307 (resolve_sr_conflict): Adjust.
309 2001-12-17 Akim Demaille <akim@epita.fr>
311 * src/output.c (output_obstack): Be static and rename as...
312 (format_obstack): this, to avoid any confusion with files.c's
314 * src/reader.h (muscle_obstack): Move to...
315 * src/output.h: here, since it's defined in output.c.
317 2001-12-17 Akim Demaille <akim@epita.fr>
319 * src/output.c (action_row, save_column, default_goto)
320 (sort_actions, matching_state, pack_vector): Better variable
323 2001-12-17 Akim Demaille <akim@epita.fr>
325 * src/output.c: Various formatting changes.
327 2001-12-17 Akim Demaille <akim@epita.fr>

331 * src/print.c (print): Work unconditionally.
332 * src/print_graph.c (print_graph): Work unconditionally.

335 2001-12-16 Marc Autret <autret_m@epita.fr>
337 * src/output.c (actions_output): Fix. When we use %no-lines,
338 there is one less line per action.
340 2001-12-16 Marc Autret <autret_m@epita.fr>
342 * src/bison.simple: Remove a useless #line directive.
343 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
344 * src/output.c (get_lines_number): New.
345 (output_parser): Adjust, now takes care about the lines of a
348 (actions_output): Computes the number of lines taken by actions.
349 (output_master_parser): Insert new skeleton which is the name of
350 the output parser file name.
352 2001-12-15 Marc Autret <autret_m@epita.fr>
354 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.

358 * src/output.c (output_gram): Keep track of the hairy one.
360 2001-12-15 Akim Demaille <akim@epita.fr>
362 Make `make distcheck' work.
364 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
365 system.h which uses libgettext.h.
367 2001-12-15 Akim Demaille <akim@epita.fr>
369 * src/nullable.c (set_nullable): Useless rules must be skipped,
370 otherwise, since we range over their symbols, we might look at a
371 nonterminal which no longer ``exists'', i.e., it is not counted in
372 `nvars', hence we overflow our arrays.
374 2001-12-15 Akim Demaille <akim@epita.fr>
376 The header can also be produced directly, without any obstack!
379 * src/files.c, src/files.h (defines_obstack): Remove.
380 (compute_header_macro): Global.
381 (defines_obstack_save): Remove.
382 * src/reader.c (parse_union_decl): No longer output to
383 defines_obstack: its content can be found in the `stype' muscle
385 (output_token_translations): Merge into...
386 (symbols_output): this.
388 (symbols_save): this.
390 * src/output.c (header_output): New.
393 2001-12-15 Akim Demaille <akim@epita.fr>
395 * src/reader.c (parse_union_decl): Instead of handling two obstack
396 simultaneously, use one to define the `stype' muscle, and use the
397 value of the latter to fill defines_obstack.
398 (copy_comment): Remove.
399 (copy_comment2): Work for a single obstack.
401 (copy_comment): this.
403 2001-12-15 Akim Demaille <akim@epita.fr>
405 * src/lex.c, src/lex.h (xgetc): No longer static.
406 * src/reader.c (parse_union_decl): Revamp.
408 2001-12-15 Akim Demaille <akim@epita.fr>
410 Still making progress in separating Bison into (i) input, (ii)
411 process, (iii) output: now we can directly output the parser file
412 without using table_obstack at all.
414 * src/files.c, src/files.h (table_obstack): Bye bye.
415 (parser_file_name): New.
416 * src/files.c (compute_output_file_names): Compute it.
417 * src/output.c (actions_output, output_parser)
418 (output_master_parser): To a file instead of an obstack.
420 2001-12-15 Akim Demaille <akim@epita.fr>
422 Attach actions to rules, instead of pre-outputting them to

426 * src/reader.c (symbol_list): Likewise.
427 (copy_action): Save the actions within the rule.
428 (packgram): Save them in rule_table.
429 * src/output.c (actions_output): New.
430 (output_parser): Use it on `%%actions'.
431 (output_rule_data): Don't free rule_table.
433 (prepare): Don't save the `action' muscle.
434 * src/bison.simple: s/%%action/%%actions/.
436 2001-12-15 Akim Demaille <akim@epita.fr>
438 * src/reader.c (copy_action): When --yacc, don't append a `;'
439 to the user action: let it fail if lacking.
440 Suggested by Arnold Robbins and Tom Tromey.
442 2001-12-14 Akim Demaille <akim@epita.fr>
444 * src/lex.c (literalchar): Simply return the char you decoded, non
445 longer mess around with obstacks and int pointers.
448 2001-12-14 Akim Demaille <akim@epita.fr>
450 * src/lex.c (literalchar): Don't escape the special characters,
451 just decode them, and keep them as char (before, eol was output as
452 the 2 char string `\n' etc.).
453 * src/output.c (output_rule_data): Use quotearg to output the
456 2001-12-13 Paul Eggert <eggert@twinsun.com>
458 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
459 Do not infringe on the global user namespace when using C++.
460 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
461 All uses of `fprintf' and `stderr' changed.
463 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
465 2001-12-13 Akim Demaille <akim@epita.fr>
467 The computation of nullable is broken: it doesn't handle empty
470 * tests/torture.at (GNU AWK Grammar): New.
471 * tests/sets.at (Nullable): New.
472 * src/nullable.c (set_nullable): Instead of blindly looping over
473 `ritems', loop over the rules, and then over their rhs's.
475 Work around Autotest bugs.
477 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
478 frame, because Autotest understand lines starting with a `+' as
479 traces from the shell. Then, they are not processed properly.
480 Admittedly an Autotest bug, but we don't have time to wait for
481 Autotest to catch up.
482 * tests/regression.at (Broken Closure): Adjust to the new table
485 * tests/sets.at: here.
487 2001-12-13 Akim Demaille <akim@epita.fr>
489 * src/closure.c (closure): Use nrules instead of playing tricks
492 2001-12-13 Akim Demaille <akim@epita.fr>
494 * src/print.c (print_actions): Output the handling of `$' as the
495 traces do: shifting the token EOF. Before EOF was treated as a
497 * tests/regression.at: Adjust some tests.
498 * src/print_graph.c (print_core): Complete the set of items via
499 closure. The next-to-final and final states are still unsatisfying,
500 but that's to be addressed elsewhere.
501 No longer output the rule numbers, but do output the state number.
502 A single loop for the shifts + gotos is enough, but picked a
503 distinct color for each.
504 (print_graph): Initialize and finalize closure.
506 2001-12-13 Akim Demaille <akim@epita.fr>
508 * src/reader.c (readgram): Remove dead code, an strip useless
510 (get_type): Remove, unused.
512 2001-12-12 Akim Demaille <akim@epita.fr>
514 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
515 on that of lib/error.c.
517 2001-12-12 Akim Demaille <akim@epita.fr>
519 Some hosts don't like `/' in includes.
521 * src/system.h: Include libgettext.h without qualifying the path.
522 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
525 2001-12-11 Marc Autret <autret_m@epita.fr>
527 * src/output.c (output_parser): Remove useless muscle.
529 2001-12-11 Marc Autret <autret_m@epita.fr>
531 * src/bison.simple: Remove #line just before %%epilogue. It
532 is now handled in ...
533 * src/reader.c (read_additionnal_code): Add the output of a
534 #line for the epilogue.
536 2001-12-10 Marc Autret <autret_m@epita.fr>
538 * src/reader.c (copy_definition): Re-use CPP-outed code which
539 replace precedent remove.
540 * src/bison.simple: Remove #line before %%prologue because
541 %%input-line is wrong at this time.
543 2001-12-10 Marc Autret <autret_m@epita.fr>
545 * src/reader.c (symbols_output): Clean up.
546 * src/output.c (output_gram, output): Clean up.
548 2001-12-10 Akim Demaille <akim@epita.fr>
550 * src/lalr.c (initialize_lookaheads): New. Extracted from...
551 * src/LR0.c (set_state_table): here.
552 * src/lalr.c (lalr): Call it.
554 2001-12-10 Akim Demaille <akim@epita.fr>
556 * src/state.h (shifts): Remove the `number' member: shifts are
557 attached to state, hence no longer need to be labelled with a

562 Now that states have a complete set of members, the linked list of
563 shifts is useless: just fill directly the state's shifts member.
565 * src/state.h (shifts): Remove the `next' member.
566 * src/LR0.c (first_state, last_state): Remove.
568 (augment_automaton): Don't look for the shifts that must be added
569 a shift on EOF: it is those of the state we looked for! But now,
570 since shifts are attached, it is no longer needed to looking
571 merely by its id: its number.
573 2001-12-10 Akim Demaille <akim@epita.fr>
575 * src/LR0.c (augment_automaton): Better variable locality.
576 Remove an impossible branch: if there is a state corresponding to
577 the start symbol being shifted, then there is shift for the start
578 symbol from the initial state.
580 2001-12-10 Akim Demaille <akim@epita.fr>
582 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
583 only when appropriate: when insert_start_shifting_state' is not
585 * tests/regression.at (Rule Line Numbers): Adjust.
587 2001-12-10 Akim Demaille <akim@epita.fr>
589 * src/LR0.c (augment_automaton): Now that all states have shifts,
590 merge the two cases addition shifts to the initial state.
592 2001-12-10 Akim Demaille <akim@epita.fr>
594 * src/lalr.c (set_state_table): Move to...
596 * src/lalr.c (lalr): Don't call it...
597 * src/LR0.c (generate_states): do it.
598 * src/LR0.h (first_state): Remove, only the table is used.
600 2001-12-10 Akim Demaille <akim@epita.fr>
602 * src/LR0.h (first_shift, first_reduction): Remove.
603 * src/lalr.c: Don't use first_shift: find shifts through the
606 2001-12-10 Akim Demaille <akim@epita.fr>
608 * src/LR0.c: Attach shifts to states as soon as they are
610 * src/lalr.c (set_state_table): Instead of assigning shifts to
611 state, just assert that the mapping was properly done.
613 2001-12-10 Akim Demaille <akim@epita.fr>
615 * src/LR0.c (insert_start_shift): Rename as...
616 (insert_start_shifting_state): this.
617 (insert_eof_shifting_state, insert_accepting_state): New.
618 (augment_automaton): Adjust.
619 Better locality of the variables.
620 When looking if the start_symbol is shifted from the initial
621 state, using `while (... symbol != start_symbol ...)' sounds
622 better than `while (... symbol < start_symbol ...)': If fail
623 to see how the order between symbols could be relevant!
625 2001-12-10 Akim Demaille <akim@epita.fr>
627 * src/getargs.h: Don't declare `spec_name_prefix' and
628 `spec_file_prefix', declared by src/files.h.
629 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
630 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
631 * src/output.c (prepare): Adjust.
632 * src/reader.c (symbols_output): Likewise.
633 * src/vmsgetargs.c: Vaguely adjust, but who cares?
635 2001-12-10 Akim Demaille <akim@epita.fr>
637 * src/muscle_tab.c (muscle_init): NULL is a better default than
640 2001-12-10 Akim Demaille <akim@epita.fr>
642 * src/reader.c (reader): Calling symbols_output once is enough.
644 2001-12-10 Akim Demaille <akim@epita.fr>
646 Now that states have a complete set of members, the linked list of
647 reductions is useless: just fill directly the state's reductions
650 * src/state.h (struct reductions): Remove member `number' and
652 * src/LR0.c (first_reduction, last_reduction): Remove.
653 (save_reductions): Don't link the new reductions, store them in
655 * src/lalr.c (set_state_table): No need to attach reductions to
656 states, it's already done.
657 * src/output.c (output_actions): No longer free the shifts, then
658 the reductions, then the states: free all the states and their
661 2001-12-10 Akim Demaille <akim@epita.fr>
663 * src/options.c (OPTN, DRTV, BOTH): New.
664 (option_table): Use them.
666 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
668 * src/options.c: Don't include stdio.h and xalloc.h for the same
671 2001-12-10 Akim Demaille <akim@epita.fr>
673 * src/output.c (output, prepare): Make sure the values of the
674 muscles `action' and `prologue' are 0-terminated.
676 2001-12-10 Akim Demaille <akim@epita.fr>
678 Clean up GCC warnings.
680 * src/reader.c (copy_action): `buf' is not used.
681 (parse_skel_decl): Be static.
682 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
683 * src/options.h (create_long_option_table): Have a real prototype.
684 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
685 (hash_delete_at): Return const void *.
686 Adjust casts to preserve the const.
688 2001-12-10 Akim Demaille <akim@epita.fr>
690 * configure.in: Require 2.52g.
691 M4 is not needed, but AUTOM4TE is.
693 * tests/Makefile.am: Adjust.
695 2001-12-10 Akim Demaille <akim@epita.fr>
697 One structure for states is enough, even though theoretically
698 there are LR(0) states and LALR(1) states.
700 * src/lalr.h (state_t): Remove.
701 (state_table): Be state_t **, not state_t *.
702 * src/state.h (core, CORE_ALLOC): Rename as...
703 (state_t, STATE_ALLOC): this.
704 Add the LALR(1) members: shifts, reductions, errs.
705 * src/LR0.c (state_table): Rename as...
706 (state_hash): this, to avoid name clashes with the global
708 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
709 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
711 2001-12-10 Akim Demaille <akim@epita.fr>
713 Bison dumps core on bash.y.
714 Reported by Pascal Bart.
716 * src/warshall.c (bitmatrix_print): New.
718 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
719 j must be the outer loop.
720 * tests/regression.at (Broken Closure): New.
722 2001-12-05 Akim Demaille <akim@epita.fr>
724 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
726 Reported by Peter Hámorský.

730 * src/conflicts.c (err_table): Remove.
731 (resolve_sr_conflict): Adjust.
732 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
734 (state_t.reductions, state_t.shifts): this.
736 2001-12-05 Akim Demaille <akim@epita.fr>
738 * src/reduce.c (reduce_grammar_tables): No longer disable the
739 removal of useless rules via CPP but via `if (0)', so that the
740 compiler still check the code is valid.
741 For instance, it should have noticed `rline' no longer exists: use
742 the `line' member of rule_t.
743 * src/gram.c (dummy, rline): Remove, unused.
745 2001-12-05 Akim Demaille <akim@epita.fr>
747 * src/output.c (pack_vector): Use assert, not berror.
748 * src/main.c (berror): Remove, unused.
750 2001-12-05 Akim Demaille <akim@epita.fr>
752 New experimental feature: if --verbose --trace output all the
753 items of a state, not only its kernel.
755 * src/print.c (print_core): If `trace_flag', then invoke closure
756 before outputting the items of the state (print_core is no longer
757 a correct name them).
758 (print_results): Invoke new_closure/free_closure if needed.
760 2001-12-05 Akim Demaille <akim@epita.fr>
762 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
763 * src/closure.c, src/closure.h (itemsetsize): Rename as...
764 (nitemset): for consistency with the rest of the project.
766 2001-12-05 Akim Demaille <akim@epita.fr>
768 * src/closure.c (print_closure): Improve.
769 (closure): Use it for printing input and output.
771 2001-12-05 Akim Demaille <akim@epita.fr>
773 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
774 indexed by nonterminals.
776 2001-12-05 Akim Demaille <akim@epita.fr>
778 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

796 * src/output.c (action_row): De-obfuscate
797 using the good o' techniques: arrays not pointers, variable
798 locality, BITISSET, RESETBIT etc.
800 2001-12-05 Akim Demaille <akim@epita.fr>
802 Pessimize the code to simplify it: from now on, all the states
803 have a valid SHIFTS, which NSHIFTS is possibly 0.
805 * src/LR0.c (shifts_new): Be global and move to..
806 * src/state.c, src/state.h: here.
807 * src/conflicts, src/lalr.c, src/output.c, src/print.c,

812 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
813 * src/conflicts.c: Use it.

819 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate

830 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
831 (print_reductions): De-obfuscate using the good o' techniques:

862 * src/LR0.c (augment_automaton): Formatting changes.
863 Better variable locality.
865 2001-12-05 Akim Demaille <akim@epita.fr>
867 * src/lalr.c (matrix_print): New.
869 Use arrays instead of pointers.
871 2001-12-05 Akim Demaille <akim@epita.fr>
873 * src/lalr.c (maxrhs): Move to...
874 * src/gram.c, src/gram.h (ritem_longest_rhs): here.

877 2001-12-05 Akim Demaille <akim@epita.fr>
879 * src/lalr.c (transpose): Free the memory allocated to the
880 argument, as it is replaced by the results by the unique caller.
881 (build_relations): Merely invoke transpose: it handles the memory
883 Improve variable locality.
884 Avoid variables used as mere abbreviations.
885 (compute_lookaheads): Use arrays instead of pointers.
887 2001-12-05 Akim Demaille <akim@epita.fr>

894 * src/derives.c (print_derives): Display the ruleno.
895 * src/lalr.c (initialize_F, transpose): Better variable locality
896 to improve readability.

899 2001-12-05 Akim Demaille <akim@epita.fr>
901 * src/lalr.c (traverse): Use arrays instead of pointers.
903 2001-12-05 Akim Demaille <akim@epita.fr>
905 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
906 the handling of squeue.
907 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
909 2001-12-05 Akim Demaille <akim@epita.fr>
911 Because useless nonterminals are now kept alive (instead of being
912 `destroyed'), we now sometimes examine them, and store information
913 related to them. Hence we need to know their number, and adjust
916 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
918 * src/LR0.c (allocate_itemsets): The memory allocated to
919 `symbol_count' was used for two different purpose: once to count
920 the number of occurrences of each symbol, and later reassigned to
921 `shift_symbol', containing the symbol that can be shifted from a
923 Deobfuscate, i.e., allocate, use and free `symbol_count' here
925 (new_itemsets): Allocate `shift_symbol' here.
926 (allocate_itemsets): symbol_count includes useless nonterminals.
928 (free_storage): Use `free', not `XFREE', for pointers that cannot
931 2001-12-05 Akim Demaille <akim@epita.fr>
933 * src/nullable.c (set_nullable): Deobfuscate the handling of
935 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
937 2001-12-05 Akim Demaille <akim@epita.fr>
939 * src/gram.c, src/gram.h (ritem_print): New.
940 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
941 (This useless function was defined only to work around VMS linkers
942 that can't handle compilation units with variables only).
943 * src/reduce.c (dump_grammar): Use it to trace the construction of
946 2001-12-04 Paul Eggert <eggert@twinsun.com>
948 * src/bison.simple (union yyalloc): Change member names
949 to be the same as the stack names.
950 (yyparse): yyptr is now union yyalloc *, not char *.
951 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
952 and may generate better code on some machines.
953 (yystpcpy): Use prototype if __STDC__ is defined, not just
954 if __cplusplus is defined.
956 2001-11-30 Akim Demaille <akim@epita.fr>
958 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
959 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
960 Gettext doesn't compile cleanly, and dies with -Werror.
961 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
962 Include WARNING_CFLAGS here.
963 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared

972 (quotearg_n_options): Abort if N is negative.
973 Avoid overflow check on hosts where size_t is 64 bits and int
974 is 32 bits, as overflow is impossible there.
975 Fix off-by-one typo that caused unnecessary reallocation.
977 2001-11-29 Paul Eggert <eggert@twinsun.com>
979 Name space cleanup in generated parser.
981 * doc/bison.texinfo (Bison Parser): Discuss system headers

986 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
987 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
989 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
990 on user names when possible.
992 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
993 Simplify test for whather <alloca.h> exists.
995 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
997 (<stdio.h>): Include if YYDEBUG.
999 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
1000 ! defined (yyoverflow) && ! defined (yymemcpy).
1002 (yymemcpy, yyparse): Rename local variables as needed so that
1003 they all begin with 'yy'.
1005 (yystrlen, yystpcpy): New functions.
1007 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1010 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
1011 instead of relying on string.h functions. Use YYSTACK_ALLOC
1012 and YYSTACK_FREE instead of malloc and free.
1014 2001-11-30 Akim Demaille <akim@epita.fr>
1016 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
1017 before their first uses.
1018 (YYBISON, YYPURE): Move to the top of the output.
1020 2001-11-30 Akim Demaille <akim@epita.fr>
1022 * tests/reduce.at (Useless Nonterminals): Fix.
1024 2001-11-30 Akim Demaille <akim@epita.fr>
1026 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1027 if body instead of `;' to pacify GCC's warnings.
1029 2001-11-30 Akim Demaille <akim@epita.fr>
1031 Instead of mapping the LHS of unused rules to -1, keep the LHS
1032 valid, but flag the rules as invalid.
1034 * src/gram.h (rule_t): `useful' is a new member.
1035 * src/print.c (print_grammar): Adjust.
1036 * src/derives.c (set_derives): Likewise.
1037 * src/reader.c (packgram, reduce_output): Likewise.
1038 * src/reduce.c (reduce_grammar_tables): Likewise.
1039 * tests/reduce.at (Underivable Rules, Useless Rules): New.
1041 2001-11-30 Akim Demaille <akim@epita.fr>
1043 * src/reduce.c (reduce_output): Formatting changes.
1044 * src/print.c (print_results, print_grammar): Likewise.
1045 * tests/regression.at (Rule Line Numbers)
1046 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
1048 2001-11-30 Akim Demaille <akim@epita.fr>
1050 * src/reduce.c (nonterminals_reduce): Instead of throwing away
1051 useless nonterminals, move them at the end of the symbol arrays.
1052 (reduce_output): Adjust.
1053 * tests/reduce.at (Useless Nonterminals): Adjust.
1055 2001-11-30 Akim Demaille <akim@epita.fr>

1064 * src/bison.simple (YYSTACK_REALLOC): Remove.
1065 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
1066 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
1068 (union yyalloc): New type.
1069 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1070 an arbitrary restriction on hosts where size_t is wider than int.
1072 (yyparse): Don't dump core if alloca or malloc fails; instead, report
1073 a parser stack overflow. Allocate just one block of memory for all
1074 three stacks, instead of allocating three blocks; this typically is
1075 faster and reduces fragmentation.
1077 Do not limit the number of items in the stack to a value that fits
1078 in 'int', as this is an arbitrary limit on hosts with 64-bit
1079 size_t and 32-bit int.
1081 2001-11-29 Marc Autret <autret_m@epita.fr>
1083 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
1084 of defining YYERROR_VERBOSE.

1094 2001-11-28 Marc Autret <autret_m@epita.fr>
1096 * src/output.h: And put its extern declaration here.
1097 * src/output.c (error_verbose): Define here.
1098 (prepare): Echo name modification.
1099 * src/getargs.h: Clean its extern declaration.
1100 * src/getargs.c (error_verbose_flag): Remove.
1101 (getargs): Remove case 'e'.

3291 unconditionally, to avoid a GCC warning and make the parser a
3294 2000-10-02 Akim Demaille <akim@epita.fr>
3296 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
3299 2000-10-02 Akim Demaille <akim@epita.fr>
3301 * src/derives.c, src/print.c, src/reduce.c: To ease the
3302 translation, move some `\n' out of the translated strings.
3304 2000-10-02 Akim Demaille <akim@epita.fr>
3306 The location tracking mechanism is precious for parse error
3307 messages. Nevertheless, it is enabled only when `@n' is used in
3308 the grammar, which is a different issue (you can use it in error
3309 message, but not in the grammar per se). Therefore, there should
3310 be another means to enable it.
3312 * src/getargs.c (getargs): Support `--locations'.
3314 * src/getargs.h (locationsflag): Export it.
3315 * src/lex.c (percent_table): Support `%locations'.
3316 * src/reader.c (yylsp_needed): Remove this variable, now replaced
3317 with `locationsflag'.
3318 * doc/bison.texinfo: Document `--locations' and `%locations'.
3320 * tests/calc.m4: Test it.
3322 For regularity of the names, replace each
3323 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3324 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3325 In addition replace each `flag' with `_flag'.
3327 2000-10-02 Akim Demaille <akim@epita.fr>
3329 Also test parse error messages, including with YYERROR_VERBOSE.
3331 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3333 Use it to check the computations.
3334 Use it to check `nonassoc' is honored.
3335 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3336 `--yyerror-verbose'.
3337 (_AT_CHECK_CALC): Adjust to this option.
3338 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3340 2000-10-02 Akim Demaille <akim@epita.fr>
3342 Test also `--verbose', `--defines' and `--name-prefix'. Testing
3343 the latter demonstrates a flaw in the handling of non debugging
3344 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3345 was used in order to simplify:
3361 unfortunately this leads to a CPP conflict when
3362 `--name-prefix=foo' is used since it produces `#define yydebug
3365 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3366 (YYDPRINTF): New macro.
3368 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3370 Also test `--verbose', `--defines' and `--name-prefix'.
3372 2000-10-02 Akim Demaille <akim@epita.fr>
3374 Improve the readability of the produced parsers.
3376 * src/bison.s1: Formatting changes.
3377 Improve the comment related to the `$' mark.
3378 (yydefault): Don't fall through to `yyresume': `goto' there.
3379 * src/output.c (output_parser): When the `$' is met, skip the end
3381 New variable, `number_of_dollar_signs', to check there's exactly
3382 one `$' in the parser skeleton.
3384 2000-10-02 Akim Demaille <akim@epita.fr>
3386 * lib/xstrdup.c: New file, from the fileutils.
3387 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3388 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3389 instead of strlen + xmalloc + strcpy.
3390 * src/symtab.c (copys): Remove, use xstrdup instead.
3392 2000-10-02 Akim Demaille <akim@epita.fr>
3394 * src/gram.h (associativity): New enum type which replaces the
3395 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3396 `right_assoc', `left_assoc' and `non_assoc'.
3397 Adjust all dependencies.
3398 * src/reader.c: Formatting changes.
3399 (LTYPESTR): Don't define it, use it as a literal in
3400 `reader_output_yylsp'.
3401 * src/symtab.h (symbol_class): New enum type which replaces the
3402 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3403 `sunknown', `stoken and `snterm'.
3405 2000-10-02 Akim Demaille <akim@epita.fr>
3407 * src/getargs.c (fixed_outfiles): Rename as...
3408 (yaccflag): for consistency and accuracy.
3409 Adjust dependencies.
3411 2000-10-02 Akim Demaille <akim@epita.fr>
3413 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3414 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
3415 difficult and introduced a lot of core dump. It turns out that
3416 Bison used an implementation of `xmalloc' based on `calloc', and
3417 at various places it does depend upon the initialization to 0. I
3418 have not tried to isolate the pertinent places, and all the former
3419 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
3420 someone should address this issue.
3422 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3423 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

3437 * src/state.h (nstates, final_state, first_state, first_shift)
3438 (first_reduction): Move their exportation from here...
3439 * src/LR0.h: to here.
3440 Adjust dependencies.
3441 * src/getargs.c (statisticsflag): New variable.
3442 Add support for `--statistics'.

3518 YYDEFACT, that makes it possible for this function to use
3521 2000-10-02 Akim Demaille <akim@epita.fr>
3523 `user_toknums' is output as a `short[]' in `output.c', while it is
3524 defined as a `int[]' in `reader.c'. For consistency with the
3525 other output tables, `user_toknums' is now defined as a table of

3568 Don't define PARAMS.
3569 * src/system.h: Define PARAMS.
3570 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
3571 purpose of config.h. system.h must not try to fix wrong
3572 definitions in config.h.

3736 2000-03-17 Akim Demaille <akim@epita.fr>
3738 On syntax errors, report the token on which we choked.
3740 * src/bison.s1 (yyparse): In the label yyerrlab, when

3786 (copy_guard): Likewise.
3788 2000-03-17 Akim Demaille <akim@epita.fr>
3790 Change the handling of @s so that they behave exactly like $s.
3791 There is now a pseudo variable @$ (readble and writable), location
3792 of the lhs of the rule (by default ranging from the location of
3793 the first symbol of the rhs, to the location of the last symbol,
3794 or, if the rhs is empty, YYLLOC).
3796 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
3798 (yyparse): When providing a default semantic action, provide a
3799 default location action.
3800 (after the $): No longer change `*YYLSP', just stack YYLOC the
3801 same way you stack YYVAL.
3802 * src/reader.c (read_declarations): Use warns.
3803 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
3804 (copy_action, case '@'): Likewise.
3805 Use a standard error message, to save useless work from

3826 2000-03-16 Akim Demaille <akim@epita.fr>
3828 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
3829 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
3830 One `#if YYDEBUG' remains, since it uses variables which are
3831 defined only if `YYDEBUG != 0'.
3833 2000-03-16 Akim Demaille <akim@epita.fr>
3835 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks
3836 and related variables so that the similarities are highlighted.

3851 * configure.in (XPFILE, XPFILE1, LOCALEDIR): Remove, handled by
3853 (VERSION_STRING): Use the third arg of AC_DEFINE_UNQUOTED.
3854 (AC_OUTPUT): Add m4/Makefile.
3855 Bump to bison 1.28a, 1.29 has never been released.
3856 * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are
3857 handled via src/Makefile.am.
3858 (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,

4496 (struct bucket): Added `alias' field.
4498 * src/reduce.c (reduce_grammar):
4499 Revise error message.
4500 (print_notices): Remove final `.' from error message.
4502 * src/reader.c (reader_output_yylsp):
4504 (readgram): Use `#if 0' around code that accepted %command
4505 inside grammar rules: The documentation doesn't allow it,
4506 and it will fail since the %command processors scan for the next %.
4507 (parse_token_decl): Extended the %token
4508 declaration to allow a multi-character symbol as an alias.
4509 (parse_thong_decl): New function.
4510 (read_declarations): Added %thong declarations.
4511 (read_declarations): Handle NOOP to deal with allowing
4512 % declarations as another means to specify the flags.
4513 (readgram): Allow %prec prior to semantics embedded in a rule.
4514 (skip_to_char, read_declarations, copy_definition)
4515 (parse_token_decl, parse_start_decl, parse_type_decl)
4516 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
4517 (get_type_name, copy_guard, copy_action, readgram)
4518 (get_type, packsymbols): Revised most error messages.
4519 Changed `fatal' to `warnxxx' to avoid aborting for error.
4520 Revised and use multiple warnxxx functions to avoid using VARARGS1.
4521 (read_declarations): Improve the error message for
4522 an invalid character. Do not abort.
4523 (read_declarations, copy_guard, copy_action): Use
4524 printable_version to avoid unprintable characters in printed output.
4525 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
4526 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
4527 Allow the type of a non-terminal can be given
4528 more than once, as long as all specifications give the same type.
4531 (output_headers, output_trailers, output, output_gram)
4532 (output_rule_data): Implement noparserflag variable.
4533 Implement toknumflag variable.
4534 (output): Call reader_output_yylsp to output LTYPESTR.
4536 * src/main.c (main):
4537 If reader sees an error, don't process the grammar.
4538 (fatals): Updated to not use VARARGS1.
4539 (printable_version, int_to_string, warn, warni, warns, warnss)
4540 (warnsss): New error reporting functions. Avoid abort for error.
4543 Added THONG and NOOP for alias processing.
4544 Added SETOPT for the new code that allows setting options with %flags.
4547 Include getopt.h. Add some extern decls.
4548 (safegetc): New function to deal with EOF gracefully.
4549 (literalchar); new function to deal with reading \ escapes.
4550 (lex): Use literalchar.
4551 (lex): Implemented "..." tokens.
4552 (literalchar, lex, parse_percent_token): Made tokenbuffer
4553 always contain the token. This includes growing the token
4554 buffer while reading an integer.
4555 (parse_percent_token): Replaced if-else statement with percent_table.
4556 (parse_percent_token): Added % declarations as another
4557 way to specify the flags -n, -l, and -r. Also added hooks for
4558 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
4559 major changes to files.c.
4560 (lex) Retain in the incoming stream a character following
4562 (skip_white_space, lex): Revised most error messages
4563 and changed fatal to warn to avoid aborting.
4564 (percent_table): Added %thong declarations.
4566 * src/gram.h: Comment changes.
4568 * src/files.c (openfiles, open_extra_files, done):
4570 and actfile file. Handle noparserflag. Both for -n switch.
4572 * src/conflicts.c (resolve_sr_conflict):
4573 Remove use of alloca.
