3 All the hacks using a final pseudo state are now useless.
5 * src/LR0.c (set_state_table): state_table holds exactly nstates.
6 * src/lalr.c (nLA): New.
7 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
8 instead of lookaheadsp from the pseudo state (nstate + 1).
10 2001-12-27 Akim Demaille <akim@epita.fr>
12 * src/output.c (action_row, token_actions): Use a state_t instead
13 of a integer, and nlookaheads instead of the following state's
17 2001-12-27 Akim Demaille <akim@epita.fr>
19 * src/conflicts.c (log_resolution, flush_shift)
20 (resolve_sr_conflict, set_conflicts, solve_conflicts)
21 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
22 (conflicts_print, print_reductions): Use a state_t instead of an
23 integer when referring to a state.
24 As much as possible, depend upon nlookaheads, instead of the
25 `lookaheadsp' member of the following state (since lookaheads of
26 successive states are successive, the difference between state n + 1
27 and n served as the number of lookaheads for state n).
28 * src/lalr.c (add_lookback_edge): Likewise.
29 * src/print.c (print_core, print_actions, print_state)
30 (print_results): Likewise.
31 * src/print_graph.c (print_core, print_actions, print_state)
32 (print_graph): Likewise.
33 * src/conflicts.h: Adjust.
35 2001-12-27 Akim Demaille <akim@epita.fr>
37 * src/bison.hairy: Formatting/comment changes.
39 Remove `register' indications.
40 Add plenty of `static'.
42 2001-12-27 Akim Demaille <akim@epita.fr>
44 * src/output.c (prepare): Drop the muscle `ntbase' which
46 * src/bison.simple: Formatting/comment changes.
47 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
48 is an undocumented synonym.
51 2001-12-22 Akim Demaille <akim@epita.fr>
53 * src/output.c (output_table_data): Change the prototype to use
54 `int' for array ranges: some invocations do pass an int, not a
56 Reported by Wayne Green.
58 2001-12-22 Akim Demaille <akim@epita.fr>
60 Some actions of web2c.y are improperly triggered.
61 Reported by Mike Castle.
63 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
64 * tests/regression.at (Web2c): Rename as...
68 2001-12-22 Akim Demaille <akim@epita.fr>
70 Reductions in web2c.y are improperly reported.
71 Reported by Mike Castle.
73 * src/conflicts.c (print_reductions): Fix.
74 * tests/regression.at (Web2c): New.
76 2001-12-18 Akim Demaille <akim@epita.fr>
78 Some host fail on `assert (!"foo")', which expands to
79 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
80 Reported by Nelson Beebee.
82 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
83 `#define it_succeeded 0' and `assert (it_succeeded)'.
85 2001-12-17 Marc Autret <autret_m@epita.fr>
87 * src/bison.simple: Don't hard code the skeleton line and filename.
88 * src/output.c (output_parser): Rename 'line' as 'output_line'.
89 New line counter 'skeleton_line' (skeleton-line muscle).
91 2001-12-17 Paul Eggert <eggert@twinsun.com>
93 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
94 YYDEBUG must be defined to a nonzero value.
96 * src/bison.simple (yytname): Do not assume that the user defines
97 YYDEBUG to a properly parenthesized expression.
99 2001-12-17 Akim Demaille <akim@epita.fr>
101 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
102 nlookaheads is a new member.
104 * src/lalr.h (nlookaheads): Remove this orphan declaration.
105 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each

110 * src/files.h, src/files.c (open_files, close_files): Remove.
111 * src/main.c (main): Don't open/close files, nor invoke lex_free,
113 * src/reader.c (reader): Do it.
115 2001-12-17 Akim Demaille <akim@epita.fr>
117 * src/conflicts.c (print_reductions): Formatting changes.
119 2001-12-17 Akim Demaille <akim@epita.fr>
121 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
123 (resolve_sr_conflict): Adjust.
125 2001-12-17 Akim Demaille <akim@epita.fr>
127 * src/output.c (output_obstack): Be static and rename as...
128 (format_obstack): this, to avoid any confusion with files.c's
130 * src/reader.h (muscle_obstack): Move to...
131 * src/output.h: here, since it's defined in output.c.
133 2001-12-17 Akim Demaille <akim@epita.fr>
135 * src/output.c (action_row, save_column, default_goto)
136 (sort_actions, matching_state, pack_vector): Better variable
139 2001-12-17 Akim Demaille <akim@epita.fr>
141 * src/output.c: Various formatting changes.
143 2001-12-17 Akim Demaille <akim@epita.fr>

151 2001-12-16 Marc Autret <autret_m@epita.fr>
153 * src/output.c (actions_output): Fix. When we use %no-lines,
154 there is one less line per action.
156 2001-12-16 Marc Autret <autret_m@epita.fr>
158 * src/bison.simple: Remove a useless #line directive.
159 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
160 * src/output.c (get_lines_number): New.
161 (output_parser): Adjust, now takes care about the lines of a
164 (actions_output): Computes the number of lines taken by actions.
165 (output_master_parser): Insert new skeleton which is the name of
166 the output parser file name.
168 2001-12-15 Marc Autret <autret_m@epita.fr>
170 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
172 2001-12-15 Marc Autret <autret_m@epita.fr>
174 * src/output.c (output_gram): Keep track of the hairy one.
176 2001-12-15 Akim Demaille <akim@epita.fr>
178 Make `make distcheck' work.
180 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
181 system.h which uses libgettext.h.
183 2001-12-15 Akim Demaille <akim@epita.fr>
185 * src/nullable.c (set_nullable): Useless rules must be skipped,
186 otherwise, since we range over their symbols, we might look at a
187 nonterminal which no longer ``exists'', i.e., it is not counted in
188 `nvars', hence we overflow our arrays.
190 2001-12-15 Akim Demaille <akim@epita.fr>
192 The header can also be produced directly, without any obstack!
195 * src/files.c, src/files.h (defines_obstack): Remove.
196 (compute_header_macro): Global.
197 (defines_obstack_save): Remove.
198 * src/reader.c (parse_union_decl): No longer output to
199 defines_obstack: its content can be found in the `stype' muscle
201 (output_token_translations): Merge into...
202 (symbols_output): this.
204 (symbols_save): this.
206 * src/output.c (header_output): New.
209 2001-12-15 Akim Demaille <akim@epita.fr>
211 * src/reader.c (parse_union_decl): Instead of handling two obstack
212 simultaneously, use one to define the `stype' muscle, and use the
213 value of the latter to fill defines_obstack.
214 (copy_comment): Remove.
215 (copy_comment2): Work for a single obstack.
217 (copy_comment): this.
219 2001-12-15 Akim Demaille <akim@epita.fr>
221 * src/lex.c, src/lex.h (xgetc): No longer static.
222 * src/reader.c (parse_union_decl): Revamp.
224 2001-12-15 Akim Demaille <akim@epita.fr>
226 Still making progress in separating Bison into (i) input, (ii)
227 process, (iii) output: now we can directly output the parser file
228 without using table_obstack at all.
230 * src/files.c, src/files.h (table_obstack): Bye bye.
231 (parser_file_name): New.
232 * src/files.c (compute_output_file_names): Compute it.
233 * src/output.c (actions_output, output_parser)
234 (output_master_parser): To a file instead of an obstack.
236 2001-12-15 Akim Demaille <akim@epita.fr>
238 Attach actions to rules, instead of pre-outputting them to
241 * src/gram.h (rule_t): action and action_line are new members.
242 * src/reader.c (symbol_list): Likewise.
243 (copy_action): Save the actions within the rule.
244 (packgram): Save them in rule_table.
245 * src/output.c (actions_output): New.
246 (output_parser): Use it on `%%actions'.
247 (output_rule_data): Don't free rule_table.
249 (prepare): Don't save the `action' muscle.
250 * src/bison.simple: s/%%action/%%actions/.
252 2001-12-15 Akim Demaille <akim@epita.fr>
254 * src/reader.c (copy_action): When --yacc, don't append a `;'
255 to the user action: let it fail if lacking.
256 Suggested by Arnold Robbins and Tom Tromey.
258 2001-12-14 Akim Demaille <akim@epita.fr>
260 * src/lex.c (literalchar): Simply return the char you decoded, non
261 longer mess around with obstacks and int pointers.
264 2001-12-14 Akim Demaille <akim@epita.fr>
266 * src/lex.c (literalchar): Don't escape the special characters,
267 just decode them, and keep them as char (before, eol was output as
268 the 2 char string `\n' etc.).
269 * src/output.c (output_rule_data): Use quotearg to output the
272 2001-12-13 Paul Eggert <eggert@twinsun.com>
274 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
275 Do not infringe on the global user namespace when using C++.
276 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
277 All uses of `fprintf' and `stderr' changed.
279 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
281 2001-12-13 Akim Demaille <akim@epita.fr>
283 The computation of nullable is broken: it doesn't handle empty
286 * tests/torture.at (GNU AWK Grammar): New.
287 * tests/sets.at (Nullable): New.
288 * src/nullable.c (set_nullable): Instead of blindly looping over
289 `ritems', loop over the rules, and then over their rhs's.
291 Work around Autotest bugs.
293 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
294 frame, because Autotest understand lines starting with a `+' as
295 traces from the shell. Then, they are not processed properly.
296 Admittedly an Autotest bug, but we don't have time to wait for
297 Autotest to catch up.
298 * tests/regression.at (Broken Closure): Adjust to the new table
301 * tests/sets.at: here.
303 2001-12-13 Akim Demaille <akim@epita.fr>
305 * src/closure.c (closure): Use nrules instead of playing tricks
308 2001-12-13 Akim Demaille <akim@epita.fr>
310 * src/print.c (print_actions): Output the handling of `$' as the
311 traces do: shifting the token EOF. Before EOF was treated as a
313 * tests/regression.at: Adjust some tests.
314 * src/print_graph.c (print_core): Complete the set of items via
315 closure. The next-to-final and final states are still unsatisfying,
316 but that's to be addressed elsewhere.
317 No longer output the rule numbers, but do output the state number.
318 A single loop for the shifts + gotos is enough, but picked a
319 distinct color for each.
320 (print_graph): Initialize and finalize closure.
322 2001-12-13 Akim Demaille <akim@epita.fr>
324 * src/reader.c (readgram): Remove dead code, an strip useless
326 (get_type): Remove, unused.
328 2001-12-12 Akim Demaille <akim@epita.fr>
330 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
331 on that of lib/error.c.
333 2001-12-12 Akim Demaille <akim@epita.fr>
335 Some hosts don't like `/' in includes.
337 * src/system.h: Include libgettext.h without qualifying the path.
338 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
341 2001-12-11 Marc Autret <autret_m@epita.fr>
343 * src/output.c (output_parser): Remove useless muscle.
345 2001-12-11 Marc Autret <autret_m@epita.fr>
347 * src/bison.simple: Remove #line just before %%epilogue. It
348 is now handled in ...
349 * src/reader.c (read_additionnal_code): Add the output of a
350 #line for the epilogue.
352 2001-12-10 Marc Autret <autret_m@epita.fr>
354 * src/reader.c (copy_definition): Re-use CPP-outed code which
355 replace precedent remove.
356 * src/bison.simple: Remove #line before %%prologue because
357 %%input-line is wrong at this time.
359 2001-12-10 Marc Autret <autret_m@epita.fr>
361 * src/reader.c (symbols_output): Clean up.
362 * src/output.c (output_gram, output): Clean up.
364 2001-12-10 Akim Demaille <akim@epita.fr>
366 * src/lalr.c (initialize_lookaheads): New. Extracted from...
367 * src/LR0.c (set_state_table): here.
368 * src/lalr.c (lalr): Call it.
370 2001-12-10 Akim Demaille <akim@epita.fr>
372 * src/state.h (shifts): Remove the `number' member: shifts are
373 attached to state, hence no longer need to be labelled with a
376 2001-12-10 Akim Demaille <akim@epita.fr>
378 Now that states have a complete set of members, the linked list of
379 shifts is useless: just fill directly the state's shifts member.
381 * src/state.h (shifts): Remove the `next' member.
382 * src/LR0.c (first_state, last_state): Remove.
384 (augment_automaton): Don't look for the shifts that must be added
385 a shift on EOF: it is those of the state we looked for! But now,
386 since shifts are attached, it is no longer needed to looking
387 merely by its id: its number.
389 2001-12-10 Akim Demaille <akim@epita.fr>
391 * src/LR0.c (augment_automaton): Better variable locality.
392 Remove an impossible branch: if there is a state corresponding to
393 the start symbol being shifted, then there is shift for the start
394 symbol from the initial state.
396 2001-12-10 Akim Demaille <akim@epita.fr>
398 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
399 only when appropriate: when insert_start_shifting_state' is not
401 * tests/regression.at (Rule Line Numbers): Adjust.
403 2001-12-10 Akim Demaille <akim@epita.fr>
405 * src/LR0.c (augment_automaton): Now that all states have shifts,
406 merge the two cases addition shifts to the initial state.
408 2001-12-10 Akim Demaille <akim@epita.fr>
410 * src/lalr.c (set_state_table): Move to...
412 * src/lalr.c (lalr): Don't call it...
413 * src/LR0.c (generate_states): do it.
414 * src/LR0.h (first_state): Remove, only the table is used.
416 2001-12-10 Akim Demaille <akim@epita.fr>
418 * src/LR0.h (first_shift, first_reduction): Remove.
419 * src/lalr.c: Don't use first_shift: find shifts through the
422 2001-12-10 Akim Demaille <akim@epita.fr>
424 * src/LR0.c: Attach shifts to states as soon as they are
426 * src/lalr.c (set_state_table): Instead of assigning shifts to
427 state, just assert that the mapping was properly done.
429 2001-12-10 Akim Demaille <akim@epita.fr>
431 * src/LR0.c (insert_start_shift): Rename as...
432 (insert_start_shifting_state): this.
433 (insert_eof_shifting_state, insert_accepting_state): New.
434 (augment_automaton): Adjust.
435 Better locality of the variables.
436 When looking if the start_symbol is shifted from the initial
437 state, using `while (... symbol != start_symbol ...)' sounds
438 better than `while (... symbol < start_symbol ...)': If fail
439 to see how the order between symbols could be relevant!
441 2001-12-10 Akim Demaille <akim@epita.fr>
443 * src/getargs.h: Don't declare `spec_name_prefix' and
444 `spec_file_prefix', declared by src/files.h.
445 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
446 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
447 * src/output.c (prepare): Adjust.
448 * src/reader.c (symbols_output): Likewise.
449 * src/vmsgetargs.c: Vaguely adjust, but who cares?
451 2001-12-10 Akim Demaille <akim@epita.fr>
453 * src/muscle_tab.c (muscle_init): NULL is a better default than
456 2001-12-10 Akim Demaille <akim@epita.fr>
458 * src/reader.c (reader): Calling symbols_output once is enough.
460 2001-12-10 Akim Demaille <akim@epita.fr>
462 Now that states have a complete set of members, the linked list of
463 reductions is useless: just fill directly the state's reductions
466 * src/state.h (struct reductions): Remove member `number' and
468 * src/LR0.c (first_reduction, last_reduction): Remove.
469 (save_reductions): Don't link the new reductions, store them in
471 * src/lalr.c (set_state_table): No need to attach reductions to
472 states, it's already done.
473 * src/output.c (output_actions): No longer free the shifts, then
474 the reductions, then the states: free all the states and their
477 2001-12-10 Akim Demaille <akim@epita.fr>
479 * src/options.c (OPTN, DRTV, BOTH): New.
480 (option_table): Use them.
482 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
484 * src/options.c: Don't include stdio.h and xalloc.h for the same
487 2001-12-10 Akim Demaille <akim@epita.fr>
489 * src/output.c (output, prepare): Make sure the values of the
490 muscles `action' and `prologue' are 0-terminated.
492 2001-12-10 Akim Demaille <akim@epita.fr>
494 Clean up GCC warnings.
496 * src/reader.c (copy_action): `buf' is not used.
497 (parse_skel_decl): Be static.
498 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
499 * src/options.h (create_long_option_table): Have a real prototype.
500 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
501 (hash_delete_at): Return const void *.
502 Adjust casts to preserve the const.
504 2001-12-10 Akim Demaille <akim@epita.fr>
506 * configure.in: Require 2.52g.
507 M4 is not needed, but AUTOM4TE is.
509 * tests/Makefile.am: Adjust.
511 2001-12-10 Akim Demaille <akim@epita.fr>
513 One structure for states is enough, even though theoretically
514 there are LR(0) states and LALR(1) states.
516 * src/lalr.h (state_t): Remove.
517 (state_table): Be state_t **, not state_t *.
518 * src/state.h (core, CORE_ALLOC): Rename as...
519 (state_t, STATE_ALLOC): this.
520 Add the LALR(1) members: shifts, reductions, errs.
521 * src/LR0.c (state_table): Rename as...
522 (state_hash): this, to avoid name clashes with the global
524 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
525 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
527 2001-12-10 Akim Demaille <akim@epita.fr>
529 Bison dumps core on bash.y.
530 Reported by Pascal Bart.
532 * src/warshall.c (bitmatrix_print): New.
534 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
535 j must be the outer loop.
536 * tests/regression.at (Broken Closure): New.
538 2001-12-05 Akim Demaille <akim@epita.fr>
540 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
542 Reported by Peter Hámorský.
544 2001-12-05 Akim Demaille <akim@epita.fr>
546 * src/conflicts.c (err_table): Remove.
547 (resolve_sr_conflict): Adjust.
548 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
550 (state_t.reductions, state_t.shifts): this.
552 2001-12-05 Akim Demaille <akim@epita.fr>
554 * src/reduce.c (reduce_grammar_tables): No longer disable the
555 removal of useless rules via CPP but via `if (0)', so that the
556 compiler still check the code is valid.
557 For instance, it should have noticed `rline' no longer exists: use
558 the `line' member of rule_t.
559 * src/gram.c (dummy, rline): Remove, unused.
561 2001-12-05 Akim Demaille <akim@epita.fr>
563 * src/output.c (pack_vector): Use assert, not berror.
564 * src/main.c (berror): Remove, unused.
566 2001-12-05 Akim Demaille <akim@epita.fr>
568 New experimental feature: if --verbose --trace output all the
569 items of a state, not only its kernel.
571 * src/print.c (print_core): If `trace_flag', then invoke closure
572 before outputting the items of the state (print_core is no longer
573 a correct name them).

719 2001-12-05 Akim Demaille <akim@epita.fr>
721 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
722 the handling of squeue.
723 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
725 2001-12-05 Akim Demaille <akim@epita.fr>
727 Because useless nonterminals are now kept alive (instead of being
728 `destroyed'), we now sometimes examine them, and store information
729 related to them. Hence we need to know their number, and adjust
732 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
734 * src/LR0.c (allocate_itemsets): The memory allocated to
735 `symbol_count' was used for two different purpose: once to count

737 `shift_symbol', containing the symbol that can be shifted from a
739 Deobfuscate, i.e., allocate, use and free `symbol_count' here
741 (new_itemsets): Allocate `shift_symbol' here.

755 * src/gram.c, src/gram.h (ritem_print): New.
756 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
757 (This useless function was defined only to work around VMS linkers
758 that can't handle compilation units with variables only).
759 * src/reduce.c (dump_grammar): Use it to trace the construction of
762 2001-12-04 Paul Eggert <eggert@twinsun.com>

788 (quotearg_n_options): Abort if N is negative.
789 Avoid overflow check on hosts where size_t is 64 bits and int
790 is 32 bits, as overflow is impossible there.
791 Fix off-by-one typo that caused unnecessary reallocation.
793 2001-11-29 Paul Eggert <eggert@twinsun.com>
795 Name space cleanup in generated parser.

809 Simplify test for whather <alloca.h> exists.
811 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.

821 (yystrlen, yystpcpy): New functions.
823 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
826 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
827 instead of relying on string.h functions. Use YYSTACK_ALLOC
828 and YYSTACK_FREE instead of malloc and free.
830 2001-11-30 Akim Demaille <akim@epita.fr>
832 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions

843 if body instead of `;' to pacify GCC's warnings.
845 2001-11-30 Akim Demaille <akim@epita.fr>
847 Instead of mapping the LHS of unused rules to -1, keep the LHS
848 valid, but flag the rules as invalid.

882 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
884 (union yyalloc): New type.
885 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
886 an arbitrary restriction on hosts where size_t is wider than int.
888 (yyparse): Don't dump core if alloca or malloc fails; instead, report
889 a parser stack overflow. Allocate just one block of memory for all
890 three stacks, instead of allocating three blocks; this typically is
891 faster and reduces fragmentation.
893 Do not limit the number of items in the stack to a value that fits
894 in 'int', as this is an arbitrary limit on hosts with 64-bit
895 size_t and 32-bit int.
897 2001-11-29 Marc Autret <autret_m@epita.fr>
899 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

952 * src/closure.c (closure): Instead of looping over word in array
953 then bits in words, loop over bits in array.
955 2001-11-28 Akim Demaille <akim@epita.fr>
957 * src/closure.c (closure): No longer optimize the special case
958 where all the bits of `ruleset[r]' are set to 0, to make the code
961 2001-11-28 Akim Demaille <akim@epita.fr>
963 * src/closure.c (closure): `r' and `c' are new variables, used to

1094 2001-11-23 Akim Demaille <akim@epita.fr>

2788 * src/files.c (open_files): Actually the `.output' file is based
2789 on the short_base_name, not base_name.

2792 2000-12-20 Akim Demaille <akim@epita.fr>

2861 2000-12-19 Akim Demaille <akim@epita.fr>
2863 * src/files.c (open_files): Yipee! We no longer need all the code

2897 prevents type checking.
2898 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
2899 cast the value to (void *): assigning a `foo *' to a `void *'

2910 * tests/atgeneral.m4: Update from CVS Autoconf.
2912 2000-11-17 Akim Demaille <akim@epita.fr>
2914 * tests/regression.m4 (%union and --defines): New test,
2915 demonstrating a current bug in the obstack implementation.
2917 2000-11-17 Akim Demaille <akim@epita.fr>

2946 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
2947 argument `data' for consistency with the prototypes.
2949 (obstack_copy, obstack_copy0): Rename the second argument as
2950 `address' for consistency. Qualify it `const'.
2951 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
2952 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify

2964 For some reason, this was not applied.
2966 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
2967 `unlink': it's no longer used.
2969 2000-11-03 Akim Demaille <akim@epita.fr>
2971 * src/files.c (skeleton_find): New function, eved out of...

2974 2000-11-03 Akim Demaille <akim@epita.fr>
2978 * src/files.c (obstack_save): New function.
2979 (done): Rename as...
2980 (output_files): this.
2982 * src/main.c (main): Don't use `atexit' to register `done', since
2983 it no longer has to remove tmp files, just call `output_files'
2984 when there are no errors.
2986 2000-11-02 Akim Demaille <akim@epita.fr>
2988 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
2989 `unlink': it's no longer used.
2990 * src/files.h: Formatting changes.

3053 2000-10-16 Akim Demaille <akim@epita.fr>
3055 * src/reader.c (copy_comment2): Expect the input stream to be on
3056 the `/' which is suspected to open a comment, instead of being
3057 called after `//' or `/*' was read.
3058 (copy_comment, copy_definition, parse_union_decl, copy_action)
3059 (copy_guard): Adjust.
3061 2000-10-16 Akim Demaille <akim@epita.fr>
3063 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

3073 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
3074 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:

3083 2000-10-04 Akim Demaille <akim@epita.fr>
3085 * doc/bison.texinfo: Various typos spotted by Neil Booth.
3087 2000-10-04 Akim Demaille <akim@epita.fr>
3089 When a literal string is used to define two different tokens,
3090 `bison -v' segfaults.
3091 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3093 * tests/regression.m4: New file.
3094 Include the core of the sample provided by Piotr Gackiewicz.
3095 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
3098 2000-10-04 Akim Demaille <akim@epita.fr>

3118 translation, move some `\n' out of the translated strings.
3120 2000-10-02 Akim Demaille <akim@epita.fr>
3122 The location tracking mechanism is precious for parse error
3123 messages. Nevertheless, it is enabled only when `@n' is used in
3124 the grammar, which is a different issue (you can use it in error
3125 message, but not in the grammar per se). Therefore, there should
3126 be another means to enable it.
3128 * src/getargs.c (getargs): Support `--locations'.
3130 * src/getargs.h (locationsflag): Export it.
3131 * src/lex.c (percent_table): Support `%locations'.
3132 * src/reader.c (yylsp_needed): Remove this variable, now replaced
3133 with `locationsflag'.
3134 * doc/bison.texinfo: Document `--locations' and `%locations'.
3136 * tests/calc.m4: Test it.
3138 For regularity of the names, replace each
3139 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3140 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3141 In addition replace each `flag' with `_flag'.
3143 2000-10-02 Akim Demaille <akim@epita.fr>
3145 Also test parse error messages, including with YYERROR_VERBOSE.
3147 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3149 Use it to check the computations.
3150 Use it to check `nonassoc' is honored.
3151 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3152 `--yyerror-verbose'.

3154 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3156 2000-10-02 Akim Demaille <akim@epita.fr>
3158 Test also `--verbose', `--defines' and `--name-prefix'. Testing
3159 the latter demonstrates a flaw in the handling of non debugging
3160 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3161 was used in order to simplify:
3177 unfortunately this leads to a CPP conflict when
3178 `--name-prefix=foo' is used since it produces `#define yydebug
3181 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3182 (YYDPRINTF): New macro.
3184 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3186 Also test `--verbose', `--defines' and `--name-prefix'.
3188 2000-10-02 Akim Demaille <akim@epita.fr>
3190 Improve the readability of the produced parsers.
3192 * src/bison.s1: Formatting changes.
3193 Improve the comment related to the `$' mark.
3194 (yydefault): Don't fall through to `yyresume': `goto' there.
3195 * src/output.c (output_parser): When the `$' is met, skip the end
3197 New variable, `number_of_dollar_signs', to check there's exactly
3198 one `$' in the parser skeleton.
3200 2000-10-02 Akim Demaille <akim@epita.fr>
3202 * lib/xstrdup.c: New file, from the fileutils.

3204 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3205 instead of strlen + xmalloc + strcpy.
3206 * src/symtab.c (copys): Remove, use xstrdup instead.
3208 2000-10-02 Akim Demaille <akim@epita.fr>
3210 * src/gram.h (associativity): New enum type which replaces the
3211 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3212 `right_assoc', `left_assoc' and `non_assoc'.
3213 Adjust all dependencies.
3214 * src/reader.c: Formatting changes.
3215 (LTYPESTR): Don't define it, use it as a literal in
3216 `reader_output_yylsp'.
3217 * src/symtab.h (symbol_class): New enum type which replaces the
3218 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3219 `sunknown', `stoken and `snterm'.
3221 2000-10-02 Akim Demaille <akim@epita.fr>
3223 * src/getargs.c (fixed_outfiles): Rename as...
3224 (yaccflag): for consistency and accuracy.
3225 Adjust dependencies.
3227 2000-10-02 Akim Demaille <akim@epita.fr>
3229 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3230 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
3231 difficult and introduced a lot of core dump. It turns out that
3232 Bison used an implementation of `xmalloc' based on `calloc', and
3233 at various places it does depend upon the initialization to 0. I
3234 have not tried to isolate the pertinent places, and all the former
3235 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
3236 someone should address this issue.
3238 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3239 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

3253 * src/state.h (nstates, final_state, first_state, first_shift)
3254 (first_reduction): Move their exportation from here...
3255 * src/LR0.h: to here.
3256 Adjust dependencies.
3257 * src/getargs.c (statisticsflag): New variable.
3258 Add support for `--statistics'.

4373 way to specify the flags -n, -l, and -r. Also added hooks for
4374 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
4375 major changes to files.c.
4376 (lex) Retain in the incoming stream a character following
