1 2001-12-17 Akim Demaille <akim@epita.fr>
3 * src/files.c (output_files): Free the output_obstack.
4 * src/main.c (main): Call print and print_graph conditionally.
5 * src/print.c (print): Work unconditionally.
6 * src/print_graph.c (print_graph): Work unconditionally.
7 * src/conflicts.c (log_resolution): Output only if verbose_flag.
9 2001-12-16 Marc Autret <autret_m@epita.fr>
11 * src/output.c (actions_output): Fix. When we use %no-lines,
12 there is one less line per action.
14 2001-12-16 Marc Autret <autret_m@epita.fr>
16 * src/bison.simple: Remove a useless #line directive.
17 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
18 * src/output.c (get_lines_number): New.
19 (output_parser): Adjust, now takes care about the lines of a
22 (actions_output): Computes the number of lines taken by actions.
23 (output_master_parser): Insert new skeleton which is the name of
24 the output parser file name.
26 2001-12-15 Marc Autret <autret_m@epita.fr>
28 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
30 2001-12-15 Marc Autret <autret_m@epita.fr>
32 * src/output.c (output_gram): Keep track of the hairy one.
34 2001-12-15 Akim Demaille <akim@epita.fr>
36 Make `make distcheck' work.
38 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
39 system.h which uses libgettext.h.
41 2001-12-15 Akim Demaille <akim@epita.fr>
43 * src/nullable.c (set_nullable): Useless rules must be skipped,
44 otherwise, since we range over their symbols, we might look at a
45 nonterminal which no longer ``exists'', i.e., it is not counted in
46 `nvars', hence we overflow our arrays.
48 2001-12-15 Akim Demaille <akim@epita.fr>
50 The header can also be produced directly, without any obstack!
53 * src/files.c, src/files.h (defines_obstack): Remove.
54 (compute_header_macro): Global.
55 (defines_obstack_save): Remove.
56 * src/reader.c (parse_union_decl): No longer output to
57 defines_obstack: its content can be found in the `stype' muscle
59 (output_token_translations): Merge into...
60 (symbols_output): this.
64 * src/output.c (header_output): New.
67 2001-12-15 Akim Demaille <akim@epita.fr>
69 * src/reader.c (parse_union_decl): Instead of handling two obstack
70 simultaneously, use one to define the `stype' muscle, and use the
71 value of the latter to fill defines_obstack.
72 (copy_comment): Remove.
73 (copy_comment2): Work for a single obstack.
77 2001-12-15 Akim Demaille <akim@epita.fr>
79 * src/lex.c, src/lex.h (xgetc): No longer static.
80 * src/reader.c (parse_union_decl): Revamp.
82 2001-12-15 Akim Demaille <akim@epita.fr>
84 Still making progress in separating Bison into (i) input, (ii)
85 process, (iii) output: now we can directly output the parser file
86 without using table_obstack at all.
88 * src/files.c, src/files.h (table_obstack): Bye bye.
89 (parser_file_name): New.
90 * src/files.c (compute_output_file_names): Compute it.
91 * src/output.c (actions_output, output_parser)
92 (output_master_parser): To a file instead of an obstack.
94 2001-12-15 Akim Demaille <akim@epita.fr>
96 Attach actions to rules, instead of pre-outputting them to
99 * src/gram.h (rule_t): action and action_line are new members.
100 * src/reader.c (symbol_list): Likewise.
101 (copy_action): Save the actions within the rule.
102 (packgram): Save them in rule_table.
103 * src/output.c (actions_output): New.
104 (output_parser): Use it on `%%actions'.
105 (output_rule_data): Don't free rule_table.
107 (prepare): Don't save the `action' muscle.
108 * src/bison.simple: s/%%action/%%actions/.
110 2001-12-15 Akim Demaille <akim@epita.fr>
112 * src/reader.c (copy_action): When --yacc, don't append a `;'
113 to the user action: let it fail if lacking.
114 Suggested by Aharon Robbins and Tom Tromey.
116 2001-12-14 Akim Demaille <akim@epita.fr>
118 * src/lex.c (literalchar): Simply return the char you decoded, non
119 longer mess around with obstacks and int pointers.
122 2001-12-14 Akim Demaille <akim@epita.fr>
124 * src/lex.c (literalchar): Don't escape the special characters,
125 just decode them, and keep them as char (before, eol was output as
126 the 2 char string `\n' etc.).
127 * src/output.c (output_rule_data): Use quotearg to output the
130 2001-12-13 Paul Eggert <eggert@twinsun.com>
132 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
133 Do not infringe on the global user namespace when using C++.
134 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
135 All uses of `fprintf' and `stderr' changed.
137 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
139 2001-12-13 Akim Demaille <akim@epita.fr>
141 The computation of nullable is broken: it doesn't handle empty
144 * tests/torture.at (GNU AWK Grammar): New.
145 * tests/sets.at (Nullable): New.
146 * src/nullable.c (set_nullable): Instead of blindly looping over
147 `ritems', loop over the rules, and then over their rhs's.
149 Work around Autotest bugs.
151 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
152 frame, because Autotest understand lines starting with a `+' as
153 traces from the shell. Then, they are not processed properly.
154 Admittedly an Autotest bug, but we don't have time to wait for
155 Autotest to catch up.
156 * tests/regression.at (Broken Closure): Adjust to the new table
159 * tests/sets.at: here.
161 2001-12-13 Akim Demaille <akim@epita.fr>
163 * src/closure.c (closure): Use nrules instead of playing tricks
166 2001-12-13 Akim Demaille <akim@epita.fr>
168 * src/print.c (print_actions): Output the handling of `$' as the
169 traces do: shifting the token EOF. Before EOF was treated as a
171 * tests/regression.at: Adjust some tests.
172 * src/print_graph.c (print_core): Complete the set of items via
173 closure. The next-to-final and final states are still unsatisfying,
174 but that's to be addressed elsewhere.
175 No longer output the rule numbers, but do output the state number.
176 A single loop for the shifts + gotos is enough, but picked a
177 distinct color for each.
178 (print_graph): Initialize and finalize closure.
180 2001-12-13 Akim Demaille <akim@epita.fr>
182 * src/reader.c (readgram): Remove dead code, an strip useless
184 (get_type): Remove, unused.
186 2001-12-12 Akim Demaille <akim@epita.fr>
188 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
189 on that of lib/error.c.
191 2001-12-12 Akim Demaille <akim@epita.fr>
193 Some hosts don't like `/' in includes.
195 * src/system.h: Include libgettext.h without qualifying the path.
196 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
199 2001-12-11 Marc Autret <autret_m@epita.fr>
201 * src/output.c (output_parser): Remove useless muscle.
203 2001-12-11 Marc Autret <autret_m@epita.fr>
205 * src/bison.simple: Remove #line just before %%epilogue. It
206 is now handled in ...
207 * src/reader.c (read_additionnal_code): Add the output of a
208 #line for the epilogue.
210 2001-12-10 Marc Autret <autret_m@epita.fr>
212 * src/reader.c (copy_definition): Re-use CPP-outed code which
213 replace precedent remove.
214 * src/bison.simple: Remove #line before %%prologue because
215 %%input-line is wrong at this time.
217 2001-12-10 Marc Autret <autret_m@epita.fr>
219 * src/reader.c (symbols_output): Clean up.
220 * src/output.c (output_gram, output): Clean up.
222 2001-12-10 Akim Demaille <akim@epita.fr>
224 * src/lalr.c (initialize_lookaheads): New. Extracted from...
225 * src/LR0.c (set_state_table): here.
226 * src/lalr.c (lalr): Call it.
228 2001-12-10 Akim Demaille <akim@epita.fr>
230 * src/state.h (shifts): Remove the `number' member: shifts are
231 attached to state, hence no longer need to be labelled with a
234 2001-12-10 Akim Demaille <akim@epita.fr>
236 Now that states have a complete set of members, the linked list of
237 shifts is useless: just fill directly the state's shifts member.
239 * src/state.h (shifts): Remove the `next' member.
240 * src/LR0.c (first_state, last_state): Remove.
242 (augment_automaton): Don't look for the shifts that must be added
243 a shift on EOF: it is those of the state we looked for! But now,
244 since shifts are attached, it is no longer needed to looking
245 merely by its id: its number.
247 2001-12-10 Akim Demaille <akim@epita.fr>
249 * src/LR0.c (augment_automaton): Better variable locality.
250 Remove an impossible branch: if there is a state corresponding to
251 the start symbol being shifted, then there is shift for the start
252 symbol from the initial state.
254 2001-12-10 Akim Demaille <akim@epita.fr>
256 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
257 only when appropriate: when insert_start_shifting_state' is not
259 * tests/regression.at (Rule Line Numbers): Adjust.
261 2001-12-10 Akim Demaille <akim@epita.fr>
263 * src/LR0.c (augment_automaton): Now that all states have shifts,
264 merge the two cases addition shifts to the initial state.
266 2001-12-10 Akim Demaille <akim@epita.fr>
268 * src/lalr.c (set_state_table): Move to...
270 * src/lalr.c (lalr): Don't call it...
271 * src/LR0.c (generate_states): do it.
272 * src/LR0.h (first_state): Remove, only the table is used.
274 2001-12-10 Akim Demaille <akim@epita.fr>
276 * src/LR0.h (first_shift, first_reduction): Remove.
277 * src/lalr.c: Don't use first_shift: find shifts through the
280 2001-12-10 Akim Demaille <akim@epita.fr>
282 * src/LR0.c: Attach shifts to states as soon as they are
284 * src/lalr.c (set_state_table): Instead of assigning shifts to
285 state, just assert that the mapping was properly done.
287 2001-12-10 Akim Demaille <akim@epita.fr>
289 * src/LR0.c (insert_start_shift): Rename as...
290 (insert_start_shifting_state): this.
291 (insert_eof_shifting_state, insert_accepting_state): New.
292 (augment_automaton): Adjust.
293 Better locality of the variables.
294 When looking if the start_symbol is shifted from the initial
295 state, using `while (... symbol != start_symbol ...)' sounds
296 better than `while (... symbol < start_symbol ...)': If fail
297 to see how the order between symbols could be relevant!
299 2001-12-10 Akim Demaille <akim@epita.fr>
301 * src/getargs.h: Don't declare `spec_name_prefix' and
302 `spec_file_prefix', declared by src/files.h.
303 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
304 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
305 * src/output.c (prepare): Adjust.
306 * src/reader.c (symbols_output): Likewise.
307 * src/vmsgetargs.c: Vaguely adjust, but who cares?
309 2001-12-10 Akim Demaille <akim@epita.fr>
311 * src/muscle_tab.c (muscle_init): NULL is a better default than
314 2001-12-10 Akim Demaille <akim@epita.fr>
316 * src/reader.c (reader): Calling symbols_output once is enough.
318 2001-12-10 Akim Demaille <akim@epita.fr>
320 Now that states have a complete set of members, the linked list of
321 reductions is useless: just fill directly the state's reductions
324 * src/state.h (struct reductions): Remove member `number' and
326 * src/LR0.c (first_reduction, last_reduction): Remove.
327 (save_reductions): Don't link the new reductions, store them in
329 * src/lalr.c (set_state_table): No need to attach reductions to
330 states, it's already done.
331 * src/output.c (output_actions): No longer free the shifts, then
332 the reductions, then the states: free all the states and their
335 2001-12-10 Akim Demaille <akim@epita.fr>
337 * src/options.c (OPTN, DRTV, BOTH): New.
338 (option_table): Use them.
340 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
342 * src/options.c: Don't include stdio.h and xalloc.h for the same
345 2001-12-10 Akim Demaille <akim@epita.fr>
347 * src/output.c (output, prepare): Make sure the values of the
348 muscles `action' and `prologue' are 0-terminated.
350 2001-12-10 Akim Demaille <akim@epita.fr>
352 Clean up GCC warnings.
354 * src/reader.c (copy_action): `buf' is not used.
355 (parse_skel_decl): Be static.
356 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
357 * src/options.h (create_long_option_table): Have a real prototype.
358 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
359 (hash_delete_at): Return const void *.
360 Adjust casts to preserve the const.
362 2001-12-10 Akim Demaille <akim@epita.fr>
364 * configure.in: Require 2.52g.
365 M4 is not needed, but AUTOM4TE is.
367 * tests/Makefile.am: Adjust.
369 2001-12-10 Akim Demaille <akim@epita.fr>
371 One structure for states is enough, even though theoretically
372 there are LR(0) states and LALR(1) states.
374 * src/lalr.h (state_t): Remove.
375 (state_table): Be state_t **, not state_t *.
376 * src/state.h (core, CORE_ALLOC): Rename as...
377 (state_t, STATE_ALLOC): this.
378 Add the LALR(1) members: shifts, reductions, errs.
379 * src/LR0.c (state_table): Rename as...
380 (state_hash): this, to avoid name clashes with the global
382 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
383 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
385 2001-12-10 Akim Demaille <akim@epita.fr>
387 Bison dumps core on bash.y.
388 Reported by Pascal Bart.
390 * src/warshall.c (bitmatrix_print): New.
392 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
393 j must be the outer loop.
394 * tests/regression.at (Broken Closure): New.
396 2001-12-05 Akim Demaille <akim@epita.fr>
398 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
400 Reported by Peter Hámorský.
402 2001-12-05 Akim Demaille <akim@epita.fr>
404 * src/conflicts.c (err_table): Remove.
405 (resolve_sr_conflict): Adjust.
406 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
408 (state_t.reductions, state_t.shifts): this.
410 2001-12-05 Akim Demaille <akim@epita.fr>
412 * src/reduce.c (reduce_grammar_tables): No longer disable the
413 removal of useless rules via CPP but via `if (0)', so that the
414 compiler still check the code is valid.
415 For instance, it should have noticed `rline' no longer exists: use
416 the `line' member of rule_t.
417 * src/gram.c (dummy, rline): Remove, unused.
419 2001-12-05 Akim Demaille <akim@epita.fr>
421 * src/output.c (pack_vector): Use assert, not berror.
422 * src/main.c (berror): Remove, unused.
424 2001-12-05 Akim Demaille <akim@epita.fr>
426 New experimental feature: if --verbose --trace output all the
427 items of a state, not only its kernel.
429 * src/print.c (print_core): If `trace_flag', then invoke closure
430 before outputting the items of the state (print_core is no longer
431 a correct name them).
432 (print_results): Invoke new_closure/free_closure if needed.
434 2001-12-05 Akim Demaille <akim@epita.fr>
436 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
437 * src/closure.c, src/closure.h (itemsetsize): Rename as...
438 (nitemset): for consistency with the rest of the project.
440 2001-12-05 Akim Demaille <akim@epita.fr>
442 * src/closure.c (print_closure): Improve.
443 (closure): Use it for printing input and output.
445 2001-12-05 Akim Demaille <akim@epita.fr>
447 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
448 indexed by nonterminals.
450 2001-12-05 Akim Demaille <akim@epita.fr>
452 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

466 * src/closure.c (set_firsts): De-obfuscate.
468 2001-12-05 Akim Demaille <akim@epita.fr>
470 * src/output.c (action_row): De-obfuscate
471 using the good o' techniques: arrays not pointers, variable
472 locality, BITISSET, RESETBIT etc.
474 2001-12-05 Akim Demaille <akim@epita.fr>
476 Pessimize the code to simplify it: from now on, all the states
477 have a valid SHIFTS, which NSHIFTS is possibly 0.
479 * src/LR0.c (shifts_new): Be global and move to..
480 * src/state.c, src/state.h: here.
481 * src/conflicts, src/lalr.c, src/output.c, src/print.c,

486 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
487 * src/conflicts.c: Use it.
488 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
489 incorrectly ``simplified''.
491 2001-12-05 Akim Demaille <akim@epita.fr>
493 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
494 using the good o' techniques: arrays not pointers, variable
495 locality, BITISSET, RESETBIT etc.
497 2001-12-05 Akim Demaille <akim@epita.fr>
499 * src/state.h (SHIFT_SYMBOL): New.
500 * src/conflicts.c: Use it to deobfuscate.

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

534 2001-12-05 Akim Demaille <akim@epita.fr>
536 * src/LR0.c (augment_automaton): Formatting changes.
537 Better variable locality.
539 2001-12-05 Akim Demaille <akim@epita.fr>
541 * src/lalr.c (matrix_print): New.
543 Use arrays instead of pointers.
545 2001-12-05 Akim Demaille <akim@epita.fr>

551 2001-12-05 Akim Demaille <akim@epita.fr>
553 * src/lalr.c (transpose): Free the memory allocated to the
554 argument, as it is replaced by the results by the unique caller.
555 (build_relations): Merely invoke transpose: it handles the memory
557 Improve variable locality.
558 Avoid variables used as mere abbreviations.
559 (compute_lookaheads): Use arrays instead of pointers.
561 2001-12-05 Akim Demaille <akim@epita.fr>

579 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
580 the handling of squeue.
581 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
583 2001-12-05 Akim Demaille <akim@epita.fr>
585 Because useless nonterminals are now kept alive (instead of being
586 `destroyed'), we now sometimes examine them, and store information
587 related to them. Hence we need to know their number, and adjust
590 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
592 * src/LR0.c (allocate_itemsets): The memory allocated to
593 `symbol_count' was used for two different purpose: once to count
594 the number of occurrences of each symbol, and later reassigned to
595 `shift_symbol', containing the symbol that can be shifted from a
597 Deobfuscate, i.e., allocate, use and free `symbol_count' here
599 (new_itemsets): Allocate `shift_symbol' here.
600 (allocate_itemsets): symbol_count includes useless nonterminals.
602 (free_storage): Use `free', not `XFREE', for pointers that cannot
605 2001-12-05 Akim Demaille <akim@epita.fr>
607 * src/nullable.c (set_nullable): Deobfuscate the handling of
609 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
611 2001-12-05 Akim Demaille <akim@epita.fr>
613 * src/gram.c, src/gram.h (ritem_print): New.
614 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
615 (This useless function was defined only to work around VMS linkers
616 that can't handle compilation units with variables only).
617 * src/reduce.c (dump_grammar): Use it to trace the construction of
620 2001-12-04 Paul Eggert <eggert@twinsun.com>

628 if __cplusplus is defined.
630 2001-11-30 Akim Demaille <akim@epita.fr>
632 * configure.in (WARNING_CFLAGS): Add -Werror when possible.

646 (quotearg_n_options): Abort if N is negative.
647 Avoid overflow check on hosts where size_t is 64 bits and int
648 is 32 bits, as overflow is impossible there.
649 Fix off-by-one typo that caused unnecessary reallocation.
651 2001-11-29 Paul Eggert <eggert@twinsun.com>
653 Name space cleanup in generated parser.

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

677 they all begin with 'yy'.
679 (yystrlen, yystpcpy): New functions.
681 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
684 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
685 instead of relying on string.h functions. Use YYSTACK_ALLOC
686 and YYSTACK_FREE instead of malloc and free.
688 2001-11-30 Akim Demaille <akim@epita.fr>
690 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
691 before their first uses.

700 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
701 if body instead of `;' to pacify GCC's warnings.
703 2001-11-30 Akim Demaille <akim@epita.fr>
705 Instead of mapping the LHS of unused rules to -1, keep the LHS
706 valid, but flag the rules as invalid.

709 * src/print.c (print_grammar): Adjust.

739 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
740 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
742 (union yyalloc): New type.
743 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
744 an arbitrary restriction on hosts where size_t is wider than int.
746 (yyparse): Don't dump core if alloca or malloc fails; instead, report
747 a parser stack overflow. Allocate just one block of memory for all
748 three stacks, instead of allocating three blocks; this typically is
749 faster and reduces fragmentation.
751 Do not limit the number of items in the stack to a value that fits
752 in 'int', as this is an arbitrary limit on hosts with 64-bit
753 size_t and 32-bit int.
755 2001-11-29 Marc Autret <autret_m@epita.fr>
757 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

2804 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
2805 argument `data' for consistency with the prototypes.
2807 (obstack_copy, obstack_copy0): Rename the second argument as
2808 `address' for consistency. Qualify it `const'.

2838 (output_files): this.
2840 * src/main.c (main): Don't use `atexit' to register `done', since
2841 it no longer has to remove tmp files, just call `output_files'
2842 when there are no errors.
2844 2000-11-02 Akim Demaille <akim@epita.fr>
2846 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

2945 2000-10-04 Akim Demaille <akim@epita.fr>
2947 When a literal string is used to define two different tokens,
2948 `bison -v' segfaults.
2949 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
2951 * tests/regression.m4: New file.
2952 Include the core of the sample provided by Piotr Gackiewicz.

2976 translation, move some `\n' out of the translated strings.
2978 2000-10-02 Akim Demaille <akim@epita.fr>
2980 The location tracking mechanism is precious for parse error
2981 messages. Nevertheless, it is enabled only when `@n' is used in
2982 the grammar, which is a different issue (you can use it in error
2983 message, but not in the grammar per se). Therefore, there should
2984 be another means to enable it.
2986 * src/getargs.c (getargs): Support `--locations'.
2988 * src/getargs.h (locationsflag): Export it.
2989 * src/lex.c (percent_table): Support `%locations'.

3001 2000-10-02 Akim Demaille <akim@epita.fr>
3003 Also test parse error messages, including with YYERROR_VERBOSE.
3005 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3007 Use it to check the computations.
3008 Use it to check `nonassoc' is honored.
3009 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3010 `--yyerror-verbose'.

3014 2000-10-02 Akim Demaille <akim@epita.fr>
3016 Test also `--verbose', `--defines' and `--name-prefix'. Testing
3017 the latter demonstrates a flaw in the handling of non debugging
3018 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3019 was used in order to simplify:
3035 unfortunately this leads to a CPP conflict when
3036 `--name-prefix=foo' is used since it produces `#define yydebug
3039 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3040 (YYDPRINTF): New macro.
3042 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3044 Also test `--verbose', `--defines' and `--name-prefix'.

3048 Improve the readability of the produced parsers.
3050 * src/bison.s1: Formatting changes.
3051 Improve the comment related to the `$' mark.
3052 (yydefault): Don't fall through to `yyresume': `goto' there.
3053 * src/output.c (output_parser): When the `$' is met, skip the end
3055 New variable, `number_of_dollar_signs', to check there's exactly
3056 one `$' in the parser skeleton.
3058 2000-10-02 Akim Demaille <akim@epita.fr>
3060 * lib/xstrdup.c: New file, from the fileutils.
3061 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3062 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3063 instead of strlen + xmalloc + strcpy.
3064 * src/symtab.c (copys): Remove, use xstrdup instead.
3066 2000-10-02 Akim Demaille <akim@epita.fr>
3068 * src/gram.h (associativity): New enum type which replaces the
3069 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3070 `right_assoc', `left_assoc' and `non_assoc'.
3071 Adjust all dependencies.
3072 * src/reader.c: Formatting changes.
3073 (LTYPESTR): Don't define it, use it as a literal in
3074 `reader_output_yylsp'.
3075 * src/symtab.h (symbol_class): New enum type which replaces the
3076 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

3082 (yaccflag): for consistency and accuracy.
3083 Adjust dependencies.
3085 2000-10-02 Akim Demaille <akim@epita.fr>
3087 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3088 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
3089 difficult and introduced a lot of core dump. It turns out that
3090 Bison used an implementation of `xmalloc' based on `calloc', and
3091 at various places it does depend upon the initialization to 0. I
3092 have not tried to isolate the pertinent places, and all the former
3093 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
3094 someone should address this issue.
3096 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.

3195 2000-10-02 Akim Demaille <akim@epita.fr>
3197 `user_toknums' is output as a `short[]' in `output.c', while it is
3198 defined as a `int[]' in `reader.c'. For consistency with the
3199 other output tables, `user_toknums' is now defined as a table of

3242 Don't define PARAMS.
3243 * src/system.h: Define PARAMS.
3244 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
3245 purpose of config.h. system.h must not try to fix wrong

3503 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

4229 (parse_percent_token): Replaced if-else statement with percent_table.
4230 (parse_percent_token): Added % declarations as another
4231 way to specify the flags -n, -l, and -r. Also added hooks for
4232 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
4233 major changes to files.c.
4234 (lex) Retain in the incoming stream a character following
4236 (skip_white_space, lex): Revised most error messages
4237 and changed fatal to warn to avoid aborting.
