1 2001-12-15 Akim Demaille <akim@epita.fr>
3 * src/lex.c, src/lex.h (xgetc): No longer static.
4 * src/reader.c (parse_union_decl): Revamp.
6 2001-12-15 Akim Demaille <akim@epita.fr>
8 Still making progress in separating Bison into (i) input, (ii)
9 process, (iii) output: now we can directly output the parser file
10 without using table_obstack at all.
12 * src/files.c, src/files.h (table_obstack): Bye bye.
13 (parser_file_name): New.
14 * src/files.c (compute_output_file_names): Compute it.
15 * src/output.c (actions_output, output_parser)
16 (output_master_parser): To a file instead of an obstack.
18 2001-12-15 Akim Demaille <akim@epita.fr>
20 Attach actions to rules, instead of pre-outputting them to
23 * src/gram.h (rule_t): action and action_line are new members.
24 * src/reader.c (symbol_list): Likewise.
25 (copy_action): Save the actions within the rule.
26 (packgram): Save them in rule_table.
27 * src/output.c (actions_output): New.
28 (output_parser): Use it on `%%actions'.
29 (output_rule_data): Don't free rule_table.
31 (prepare): Don't save the `action' muscle.
32 * src/bison.simple: s/%%action/%%actions/.
34 2001-12-15 Akim Demaille <akim@epita.fr>
36 * src/reader.c (copy_action): When --yacc, don't append a `;'
37 to the user action: let it fail if lacking.
38 Suggested by Aharon Robbins and Tom Tromey.
40 2001-12-14 Akim Demaille <akim@epita.fr>
42 * src/lex.c (literalchar): Simply return the char you decoded, non
43 longer mess around with obstacks and int pointers.
46 2001-12-14 Akim Demaille <akim@epita.fr>
48 * src/lex.c (literalchar): Don't escape the special characters,
49 just decode them, and keep them as char (before, eol was output as
50 the 2 char string `\n' etc.).
51 * src/output.c (output_rule_data): Use quotearg to output the
54 2001-12-13 Paul Eggert <eggert@twinsun.com>
56 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
57 Do not infringe on the global user namespace when using C++.
58 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
59 All uses of `fprintf' and `stderr' changed.
61 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
63 2001-12-13 Akim Demaille <akim@epita.fr>
65 The computation of nullable is broken: it doesn't handle empty
68 * tests/torture.at (GNU AWK Grammar): New.
69 * tests/sets.at (Nullable): New.
70 * src/nullable.c (set_nullable): Instead of blindly looping over
71 `ritems', loop over the rules, and then over their rhs's.
73 Work around Autotest bugs.
75 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
76 frame, because Autotest understand lines starting with a `+' as
77 traces from the shell. Then, they are not processed properly.
78 Admittedly an Autotest bug, but we don't have time to wait for
80 * tests/regression.at (Broken Closure): Adjust to the new table
83 * tests/sets.at: here.
85 2001-12-13 Akim Demaille <akim@epita.fr>
87 * src/closure.c (closure): Use nrules instead of playing tricks
90 2001-12-13 Akim Demaille <akim@epita.fr>
92 * src/print.c (print_actions): Output the handling of `$' as the
93 traces do: shifting the token EOF. Before EOF was treated as a
95 * tests/regression.at: Adjust some tests.
96 * src/print_graph.c (print_core): Complete the set of items via
97 closure. The next-to-final and final states are still unsatisfying,
98 but that's to be addressed elsewhere.
99 No longer output the rule numbers, but do output the state number.
100 A single loop for the shifts + gotos is enough, but picked a
101 distinct color for each.
102 (print_graph): Initialize and finalize closure.
104 2001-12-13 Akim Demaille <akim@epita.fr>
106 * src/reader.c (readgram): Remove dead code, an strip useless
108 (get_type): Remove, unused.
110 2001-12-12 Akim Demaille <akim@epita.fr>
112 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
113 on that of lib/error.c.
115 2001-12-12 Akim Demaille <akim@epita.fr>
117 Some hosts don't like `/' in includes.
119 * src/system.h: Include libgettext.h without qualifying the path.
120 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
123 2001-12-11 Marc Autret <autret_m@epita.fr>
125 * src/output.c (output_parser): Remove useless muscle.
127 2001-12-11 Marc Autret <autret_m@epita.fr>
129 * src/bison.simple: Remove #line just before %%epilogue. It
130 is now handled in ...
131 * src/reader.c (read_additionnal_code): Add the output of a
132 #line for the epilogue.
134 2001-12-10 Marc Autret <autret_m@epita.fr>
136 * src/reader.c (copy_definition): Re-use CPP-outed code which
137 replace precedent remove.
138 * src/bison.simple: Remove #line before %%prologue because
139 %%input-line is wrong at this time.
141 2001-12-10 Marc Autret <autret_m@epita.fr>
143 * src/reader.c (symbols_output): Clean up.
144 * src/output.c (output_gram, output): Clean up.
146 2001-12-10 Akim Demaille <akim@epita.fr>
148 * src/lalr.c (initialize_lookaheads): New. Extracted from...
149 * src/LR0.c (set_state_table): here.
150 * src/lalr.c (lalr): Call it.
152 2001-12-10 Akim Demaille <akim@epita.fr>
154 * src/state.h (shifts): Remove the `number' member: shifts are
155 attached to state, hence no longer need to be labelled with a
158 2001-12-10 Akim Demaille <akim@epita.fr>
160 Now that states have a complete set of members, the linked list of
161 shifts is useless: just fill directly the state's shifts member.
163 * src/state.h (shifts): Remove the `next' member.
164 * src/LR0.c (first_state, last_state): Remove.
166 (augment_automaton): Don't look for the shifts that must be added
167 a shift on EOF: it is those of the state we looked for! But now,
168 since shifts are attached, it is no longer needed to looking
169 merely by its id: its number.
171 2001-12-10 Akim Demaille <akim@epita.fr>
173 * src/LR0.c (augment_automaton): Better variable locality.
174 Remove an impossible branch: if there is a state corresponding to
175 the start symbol being shifted, then there is shift for the start
176 symbol from the initial state.
178 2001-12-10 Akim Demaille <akim@epita.fr>
180 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
181 only when appropriate: when insert_start_shifting_state' is not
183 * tests/regression.at (Rule Line Numbers): Adjust.
185 2001-12-10 Akim Demaille <akim@epita.fr>
187 * src/LR0.c (augment_automaton): Now that all states have shifts,
188 merge the two cases addition shifts to the initial state.
190 2001-12-10 Akim Demaille <akim@epita.fr>
192 * src/lalr.c (set_state_table): Move to...
194 * src/lalr.c (lalr): Don't call it...
195 * src/LR0.c (generate_states): do it.
196 * src/LR0.h (first_state): Remove, only the table is used.
198 2001-12-10 Akim Demaille <akim@epita.fr>
200 * src/LR0.h (first_shift, first_reduction): Remove.
201 * src/lalr.c: Don't use first_shift: find shifts through the
204 2001-12-10 Akim Demaille <akim@epita.fr>
206 * src/LR0.c: Attach shifts to states as soon as they are
208 * src/lalr.c (set_state_table): Instead of assigning shifts to
209 state, just assert that the mapping was properly done.
211 2001-12-10 Akim Demaille <akim@epita.fr>
213 * src/LR0.c (insert_start_shift): Rename as...
214 (insert_start_shifting_state): this.
215 (insert_eof_shifting_state, insert_accepting_state): New.
216 (augment_automaton): Adjust.
217 Better locality of the variables.
218 When looking if the start_symbol is shifted from the initial
219 state, using `while (... symbol != start_symbol ...)' sounds
220 better than `while (... symbol < start_symbol ...)': If fail
221 to see how the order between symbols could be relevant!
223 2001-12-10 Akim Demaille <akim@epita.fr>
225 * src/getargs.h: Don't declare `spec_name_prefix' and
226 `spec_file_prefix', declared by src/files.h.
227 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
228 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
229 * src/output.c (prepare): Adjust.
230 * src/reader.c (symbols_output): Likewise.
231 * src/vmsgetargs.c: Vaguely adjust, but who cares?
233 2001-12-10 Akim Demaille <akim@epita.fr>
235 * src/muscle_tab.c (muscle_init): NULL is a better default than
238 2001-12-10 Akim Demaille <akim@epita.fr>
240 * src/reader.c (reader): Calling symbols_output once is enough.
242 2001-12-10 Akim Demaille <akim@epita.fr>
244 Now that states have a complete set of members, the linked list of
245 reductions is useless: just fill directly the state's reductions
248 * src/state.h (struct reductions): Remove member `number' and
250 * src/LR0.c (first_reduction, last_reduction): Remove.
251 (save_reductions): Don't link the new reductions, store them in
253 * src/lalr.c (set_state_table): No need to attach reductions to
254 states, it's already done.
255 * src/output.c (output_actions): No longer free the shifts, then
256 the reductions, then the states: free all the states and their
259 2001-12-10 Akim Demaille <akim@epita.fr>
261 * src/options.c (OPTN, DRTV, BOTH): New.
262 (option_table): Use them.
264 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
266 * src/options.c: Don't include stdio.h and xalloc.h for the same
269 2001-12-10 Akim Demaille <akim@epita.fr>
271 * src/output.c (output, prepare): Make sure the values of the
272 muscles `action' and `prologue' are 0-terminated.
274 2001-12-10 Akim Demaille <akim@epita.fr>
276 Clean up GCC warnings.
278 * src/reader.c (copy_action): `buf' is not used.
279 (parse_skel_decl): Be static.
280 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
281 * src/options.h (create_long_option_table): Have a real prototype.
282 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
283 (hash_delete_at): Return const void *.
284 Adjust casts to preserve the const.
286 2001-12-10 Akim Demaille <akim@epita.fr>
288 * configure.in: Require 2.52g.
289 M4 is not needed, but AUTOM4TE is.
291 * tests/Makefile.am: Adjust.
293 2001-12-10 Akim Demaille <akim@epita.fr>
295 One structure for states is enough, even though theoretically
296 there are LR(0) states and LALR(1) states.
298 * src/lalr.h (state_t): Remove.
299 (state_table): Be state_t **, not state_t *.
300 * src/state.h (core, CORE_ALLOC): Rename as...
301 (state_t, STATE_ALLOC): this.
302 Add the LALR(1) members: shifts, reductions, errs.
303 * src/LR0.c (state_table): Rename as...
304 (state_hash): this, to avoid name clashes with the global
306 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
307 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
309 2001-12-10 Akim Demaille <akim@epita.fr>
311 Bison dumps core on bash.y.
312 Reported by Pascal Bart.
314 * src/warshall.c (bitmatrix_print): New.
316 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
317 j must be the outer loop.
318 * tests/regression.at (Broken Closure): New.
320 2001-12-05 Akim Demaille <akim@epita.fr>
322 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
324 Reported by Peter Hámorský.
326 2001-12-05 Akim Demaille <akim@epita.fr>
328 * src/conflicts.c (err_table): Remove.
329 (resolve_sr_conflict): Adjust.
330 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
332 (state_t.reductions, state_t.shifts): this.
334 2001-12-05 Akim Demaille <akim@epita.fr>
336 * src/reduce.c (reduce_grammar_tables): No longer disable the
337 removal of useless rules via CPP but via `if (0)', so that the
338 compiler still check the code is valid.
339 For instance, it should have noticed `rline' no longer exists: use
340 the `line' member of rule_t.
341 * src/gram.c (dummy, rline): Remove, unused.
343 2001-12-05 Akim Demaille <akim@epita.fr>
345 * src/output.c (pack_vector): Use assert, not berror.
346 * src/main.c (berror): Remove, unused.
348 2001-12-05 Akim Demaille <akim@epita.fr>
350 New experimental feature: if --verbose --trace output all the
351 items of a state, not only its kernel.
353 * src/print.c (print_core): If `trace_flag', then invoke closure
354 before outputting the items of the state (print_core is no longer
355 a correct name them).
356 (print_results): Invoke new_closure/free_closure if needed.
358 2001-12-05 Akim Demaille <akim@epita.fr>
360 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
361 * src/closure.c, src/closure.h (itemsetsize): Rename as...
362 (nitemset): for consistency with the rest of the project.
364 2001-12-05 Akim Demaille <akim@epita.fr>
366 * src/closure.c (print_closure): Improve.
367 (closure): Use it for printing input and output.
369 2001-12-05 Akim Demaille <akim@epita.fr>
371 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
372 indexed by nonterminals.
374 2001-12-05 Akim Demaille <akim@epita.fr>
376 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

392 2001-12-05 Akim Demaille <akim@epita.fr>
394 * src/output.c (action_row): De-obfuscate
395 using the good o' techniques: arrays not pointers, variable
396 locality, BITISSET, RESETBIT etc.
398 2001-12-05 Akim Demaille <akim@epita.fr>
400 Pessimize the code to simplify it: from now on, all the states
401 have a valid SHIFTS, which NSHIFTS is possibly 0.
403 * src/LR0.c (shifts_new): Be global and move to..
404 * src/state.c, src/state.h: here.
405 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
406 * src/print_graph: Adjust.

410 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
411 * src/conflicts.c: Use it.
412 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
413 incorrectly ``simplified''.
415 2001-12-05 Akim Demaille <akim@epita.fr>
417 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
418 using the good o' techniques: arrays not pointers, variable
419 locality, BITISSET, RESETBIT etc.
421 2001-12-05 Akim Demaille <akim@epita.fr>
423 * src/state.h (SHIFT_SYMBOL): New.
424 * src/conflicts.c: Use it to deobfuscate.
426 2001-12-05 Akim Demaille <akim@epita.fr>
428 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
429 (print_reductions): De-obfuscate using the good o' techniques:

432 2001-12-05 Akim Demaille <akim@epita.fr>
434 * src/conflicts.c (print_reductions): Arrays, not pointers.
437 2001-12-05 Akim Demaille <akim@epita.fr>

458 2001-12-05 Akim Demaille <akim@epita.fr>
460 * src/LR0.c (augment_automaton): Formatting changes.
461 Better variable locality.
463 2001-12-05 Akim Demaille <akim@epita.fr>
465 * src/lalr.c (matrix_print): New.
467 Use arrays instead of pointers.
469 2001-12-05 Akim Demaille <akim@epita.fr>
471 * src/lalr.c (maxrhs): Move to...
472 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
473 * src/lalr.c (build_relations): Adjust.
475 2001-12-05 Akim Demaille <akim@epita.fr>
477 * src/lalr.c (transpose): Free the memory allocated to the
478 argument, as it is replaced by the results by the unique caller.
479 (build_relations): Merely invoke transpose: it handles the memory
481 Improve variable locality.
482 Avoid variables used as mere abbreviations.
483 (compute_lookaheads): Use arrays instead of pointers.
485 2001-12-05 Akim Demaille <akim@epita.fr>
487 * src/lalr.c (initialize_F): Improve variable locality.
488 Avoid variables used as mere abbreviations.
490 2001-12-05 Akim Demaille <akim@epita.fr>
492 * src/derives.c (print_derives): Display the ruleno.
493 * src/lalr.c (initialize_F, transpose): Better variable locality
494 to improve readability.
495 Avoid variables used as mere abbreviations.
497 2001-12-05 Akim Demaille <akim@epita.fr>
499 * src/lalr.c (traverse): Use arrays instead of pointers.
501 2001-12-05 Akim Demaille <akim@epita.fr>
503 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
504 the handling of squeue.
505 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
507 2001-12-05 Akim Demaille <akim@epita.fr>
509 Because useless nonterminals are now kept alive (instead of being
510 `destroyed'), we now sometimes examine them, and store information
511 related to them. Hence we need to know their number, and adjust
514 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
516 * src/LR0.c (allocate_itemsets): The memory allocated to
517 `symbol_count' was used for two different purpose: once to count
518 the number of occurrences of each symbol, and later reassigned to
519 `shift_symbol', containing the symbol that can be shifted from a
521 Deobfuscate, i.e., allocate, use and free `symbol_count' here
523 (new_itemsets): Allocate `shift_symbol' here.
524 (allocate_itemsets): symbol_count includes useless nonterminals.
526 (free_storage): Use `free', not `XFREE', for pointers that cannot
529 2001-12-05 Akim Demaille <akim@epita.fr>
531 * src/nullable.c (set_nullable): Deobfuscate the handling of
533 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
535 2001-12-05 Akim Demaille <akim@epita.fr>
537 * src/gram.c, src/gram.h (ritem_print): New.
538 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
539 (This useless function was defined only to work around VMS linkers
540 that can't handle compilation units with variables only).
541 * src/reduce.c (dump_grammar): Use it to trace the construction of
544 2001-12-04 Paul Eggert <eggert@twinsun.com>
546 * src/bison.simple (union yyalloc): Change member names
547 to be the same as the stack names.
548 (yyparse): yyptr is now union yyalloc *, not char *.
549 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
550 and may generate better code on some machines.
551 (yystpcpy): Use prototype if __STDC__ is defined, not just
552 if __cplusplus is defined.
554 2001-11-30 Akim Demaille <akim@epita.fr>
556 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
557 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
558 Gettext doesn't compile cleanly, and dies with -Werror.
559 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
560 Include WARNING_CFLAGS here.
561 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
562 before being defined.
564 2001-11-27 Paul Eggert <eggert@twinsun.com>
566 * lib/quotearg.h (quotearg_n, quotearg_n_style):
567 First arg is int, not unsigned.

627 2001-11-30 Akim Demaille <akim@epita.fr>

667 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
668 an arbitrary restriction on hosts where size_t is wider than int.
670 (yyparse): Don't dump core if alloca or malloc fails; instead, report
671 a parser stack overflow. Allocate just one block of memory for all
672 three stacks, instead of allocating three blocks; this typically is
673 faster and reduces fragmentation.
675 Do not limit the number of items in the stack to a value that fits
676 in 'int', as this is an arbitrary limit on hosts with 64-bit
677 size_t and 32-bit int.

2762 (output_files): this.
2764 * src/main.c (main): Don't use `atexit' to register `done', since
2765 it no longer has to remove tmp files, just call `output_files'
2766 when there are no errors.
2768 2000-11-02 Akim Demaille <akim@epita.fr>
2770 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
2771 `unlink': it's no longer used.
2772 * src/files.h: Formatting changes.
2774 2000-11-02 Akim Demaille <akim@epita.fr>

2798 2000-11-01 Akim Demaille <akim@epita.fr>
2801 Change each use of `faction' into a use of `action_obstack'.

2835 2000-10-16 Akim Demaille <akim@epita.fr>
2837 * src/reader.c (copy_comment2): Expect the input stream to be on
2838 the `/' which is suspected to open a comment, instead of being
2839 called after `//' or `/*' was read.
2840 (copy_comment, copy_definition, parse_union_decl, copy_action)
2841 (copy_guard): Adjust.
2843 2000-10-16 Akim Demaille <akim@epita.fr>

2865 2000-10-04 Akim Demaille <akim@epita.fr>
2867 * doc/bison.texinfo: Various typos spotted by Neil Booth.
2869 2000-10-04 Akim Demaille <akim@epita.fr>
2871 When a literal string is used to define two different tokens,
2872 `bison -v' segfaults.
2873 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
2875 * tests/regression.m4: New file.
2876 Include the core of the sample provided by Piotr Gackiewicz.
2877 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
2880 2000-10-04 Akim Demaille <akim@epita.fr>
2882 * src/reader.c (parse_expect_decl): Keep `count' within the size

2894 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
2897 2000-10-02 Akim Demaille <akim@epita.fr>

2900 translation, move some `\n' out of the translated strings.
2902 2000-10-02 Akim Demaille <akim@epita.fr>
2904 The location tracking mechanism is precious for parse error
2905 messages. Nevertheless, it is enabled only when `@n' is used in
2906 the grammar, which is a different issue (you can use it in error
2907 message, but not in the grammar per se). Therefore, there should
2908 be another means to enable it.
2910 * src/getargs.c (getargs): Support `--locations'.
2912 * src/getargs.h (locationsflag): Export it.
2913 * src/lex.c (percent_table): Support `%locations'.
2914 * src/reader.c (yylsp_needed): Remove this variable, now replaced
2915 with `locationsflag'.
2916 * doc/bison.texinfo: Document `--locations' and `%locations'.
2918 * tests/calc.m4: Test it.
2920 For regularity of the names, replace each
2921 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
2922 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
2923 In addition replace each `flag' with `_flag'.
2925 2000-10-02 Akim Demaille <akim@epita.fr>
2927 Also test parse error messages, including with YYERROR_VERBOSE.
2929 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
2931 Use it to check the computations.
2932 Use it to check `nonassoc' is honored.
2933 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
2934 `--yyerror-verbose'.

2936 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
2938 2000-10-02 Akim Demaille <akim@epita.fr>
2940 Test also `--verbose', `--defines' and `--name-prefix'. Testing
2941 the latter demonstrates a flaw in the handling of non debugging
2942 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
2943 was used in order to simplify:
2959 unfortunately this leads to a CPP conflict when
2960 `--name-prefix=foo' is used since it produces `#define yydebug
2963 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
2964 (YYDPRINTF): New macro.
2966 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
2968 Also test `--verbose', `--defines' and `--name-prefix'.

2972 Improve the readability of the produced parsers.
2974 * src/bison.s1: Formatting changes.
2975 Improve the comment related to the `$' mark.
2976 (yydefault): Don't fall through to `yyresume': `goto' there.
2977 * src/output.c (output_parser): When the `$' is met, skip the end
2979 New variable, `number_of_dollar_signs', to check there's exactly
2980 one `$' in the parser skeleton.
2982 2000-10-02 Akim Demaille <akim@epita.fr>
2984 * lib/xstrdup.c: New file, from the fileutils.
2985 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
2986 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
2987 instead of strlen + xmalloc + strcpy.
2988 * src/symtab.c (copys): Remove, use xstrdup instead.
2990 2000-10-02 Akim Demaille <akim@epita.fr>
2992 * src/gram.h (associativity): New enum type which replaces the
2993 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
2994 `right_assoc', `left_assoc' and `non_assoc'.
2995 Adjust all dependencies.
2996 * src/reader.c: Formatting changes.
2997 (LTYPESTR): Don't define it, use it as a literal in
2998 `reader_output_yylsp'.
2999 * src/symtab.h (symbol_class): New enum type which replaces the
3000 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
3001 `sunknown', `stoken and `snterm'.

3005 * src/getargs.c (fixed_outfiles): Rename as...
3006 (yaccflag): for consistency and accuracy.
3007 Adjust dependencies.
3009 2000-10-02 Akim Demaille <akim@epita.fr>
3011 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
3012 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
3013 difficult and introduced a lot of core dump. It turns out that
3014 Bison used an implementation of `xmalloc' based on `calloc', and
3015 at various places it does depend upon the initialization to 0. I
3016 have not tried to isolate the pertinent places, and all the former
3017 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
3018 someone should address this issue.
3020 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
3021 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

3119 2000-10-02 Akim Demaille <akim@epita.fr>
3121 `user_toknums' is output as a `short[]' in `output.c', while it is
3122 defined as a `int[]' in `reader.c'. For consistency with the
3123 other output tables, `user_toknums' is now defined as a table of

3166 Don't define PARAMS.
3167 * src/system.h: Define PARAMS.

3392 or, if the rhs is empty, YYLLOC).
3394 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
3396 (yyparse): When providing a default semantic action, provide a
3397 default location action.

3399 same way you stack YYVAL.
3400 * src/reader.c (read_declarations): Use warns.
3401 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

3427 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
3428 One `#if YYDEBUG' remains, since it uses variables which are

4098 (print_notices): Remove final `.' from error message.
4100 * src/reader.c (reader_output_yylsp):
4102 (readgram): Use `#if 0' around code that accepted %command
4103 inside grammar rules: The documentation doesn't allow it,
4104 and it will fail since the %command processors scan for the next %.
4105 (parse_token_decl): Extended the %token
4106 declaration to allow a multi-character symbol as an alias.
4107 (parse_thong_decl): New function.
4108 (read_declarations): Added %thong declarations.
4109 (read_declarations): Handle NOOP to deal with allowing
4110 % declarations as another means to specify the flags.

4115 (get_type_name, copy_guard, copy_action, readgram)
4116 (get_type, packsymbols): Revised most error messages.
4117 Changed `fatal' to `warnxxx' to avoid aborting for error.
4118 Revised and use multiple warnxxx functions to avoid using VARARGS1.
4119 (read_declarations): Improve the error message for
4120 an invalid character. Do not abort.
4121 (read_declarations, copy_guard, copy_action): Use
4122 printable_version to avoid unprintable characters in printed output.
4123 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
4124 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
4125 Allow the type of a non-terminal can be given
4126 more than once, as long as all specifications give the same type.
4129 (output_headers, output_trailers, output, output_gram)
4130 (output_rule_data): Implement noparserflag variable.
4131 Implement toknumflag variable.
4132 (output): Call reader_output_yylsp to output LTYPESTR.
4134 * src/main.c (main):
4135 If reader sees an error, don't process the grammar.
4136 (fatals): Updated to not use VARARGS1.
4137 (printable_version, int_to_string, warn, warni, warns, warnss)
4138 (warnsss): New error reporting functions. Avoid abort for error.
4141 Added THONG and NOOP for alias processing.
4142 Added SETOPT for the new code that allows setting options with %flags.
4145 Include getopt.h. Add some extern decls.
4146 (safegetc): New function to deal with EOF gracefully.
4147 (literalchar); new function to deal with reading \ escapes.
4148 (lex): Use literalchar.
4149 (lex): Implemented "..." tokens.
4150 (literalchar, lex, parse_percent_token): Made tokenbuffer
4151 always contain the token. This includes growing the token
4152 buffer while reading an integer.
4153 (parse_percent_token): Replaced if-else statement with percent_table.
4154 (parse_percent_token): Added % declarations as another
4155 way to specify the flags -n, -l, and -r. Also added hooks for
4156 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
4157 major changes to files.c.
4158 (lex) Retain in the incoming stream a character following
4160 (skip_white_space, lex): Revised most error messages
4161 and changed fatal to warn to avoid aborting.
4162 (percent_table): Added %thong declarations.
4164 * src/gram.h: Comment changes.
4166 * src/files.c (openfiles, open_extra_files, done):
4168 and actfile file. Handle noparserflag. Both for -n switch.
