1 2002-02-07 Akim Demaille <akim@epita.fr>
3 * tests/regression.at, tests/torture.at, tests/calc.at: Adjust to
4 newest Autotest, where `.' is not in the PATH.
6 2002-02-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
8 * src/reader.c (copy_at): Detect invalid @N values.
10 2002-02-07 Akim Demaille <akim@epita.fr>
12 * tests/input.at: New.
14 2002-01-29 Paul Eggert <eggert@twinsun.com>
16 * src/bison.simple (YYSIZE_T): Do not define merely because
17 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
18 On some platforms, <alloca.h> does not declare YYSTD (size_t).
20 2002-01-25 Akim Demaille <akim@epita.fr>
22 * tests/regression.at (%nonassoc and eof): New.
23 Suggested by Robert Anisko.
25 2002-01-23 Akim Demaille <akim@epita.fr>
29 2002-01-23 Akim Demaille <akim@epita.fr>
31 * src/getargs.c (version): Bump to 2002.
32 Patch the PO files to help translators.
34 2002-01-22 Akim Demaille <akim@epita.fr>
36 Bison dumps core when trying to complain about broken input files.
37 Reported by Cris van Pelt.
39 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
40 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
42 (Invalid inputs): Strengthen: exercise parse_percent_token.
44 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
48 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
50 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
52 2002-01-20 Marc Autret <marc@gnu.org>
54 * src/system.h: Need to define __attribute__ away for non-GCC
55 compilers as well (i.e. the vendor C compiler).
56 Suggested by Albert Chin-A-Young.
58 2002-01-19 Marc Autret <marc@gnu.org>
60 * tests/output.at: New test.
61 * src/files.c (compute_base_names): Don't map extensions when
62 the YACC flag is set, use defaults.
63 Reported by Evgeny Stambulchik.
65 2002-01-19 Marc Autret <marc@gnu.org>
67 * configure.in, doc/version.texi: Bump to 1.31a.
69 2002-01-14 Akim Demaille <akim@epita.fr>
73 2002-01-14 Akim Demaille <akim@epita.fr>
75 * tests/regression.at (Invalid CPP headers): Remove.
77 2002-01-12 Akim Demaille <akim@epita.fr>
81 2002-01-12 Akim Demaille <akim@epita.fr>
83 * lib/Makefile.am (EXTRA_DIST): Add strnlen.c: Automake is still
84 not using Autoconf traces and does not see Autoconf's AC_LIBOBJ.
86 2002-01-11 Akim Demaille <akim@epita.fr>
90 2002-01-11 Akim Demaille <akim@epita.fr>
92 * configure.in: Use AC_FUNC_STRNLEN.
93 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
95 2002-01-09 Akim Demaille <akim@epita.fr>
99 2002-01-09 Akim Demaille <akim@epita.fr>
101 * configure.in (WERROR_CFLAGS): Compute it.
102 * src/Makefile.am (CFLAGS): Pass it.
103 * tests/atlocal.in (CFLAGS): Idem.
105 2002-01-08 Akim Demaille <akim@epita.fr>
107 * lib/Makefile.am (libbison_a_SOURCES): Add xstrndup.c.
108 * src/getargs.c (AS_FILE_NAME): New.
109 (getargs): Use it to convert DOSish file names.
110 * src/files.c (base_name): Rename as full_base_name to avoid
111 clashes with `base_name ()'.
112 (get_extension_index): Remove.
113 (filename_split): New.
114 (compute_base_names): N-th rewrite, using filename_split.
116 2002-01-08 Akim Demaille <akim@epita.fr>
118 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c,
119 * lib/xstrndup.c, lib/strchr.c:
120 New, stolen from the Fileutils 4.1.
121 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
122 * configure.in: Check for the presence of memrchr, strchr,
123 strnlen, and of their prototypes.
124 Don't check for strndup: we no longer use it.
125 * src/system.h: Adjust the prototypes.
127 2002-01-07 Akim Demaille <akim@epita.fr>
129 * src/conflicts.c (count_rr_conflicts): The previous RR conflicts
130 patch was improperly applied: fix it.
132 2002-01-07 Akim Demaille <akim@epita.fr>
134 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
135 'switch' without a following semicolon.
136 * tests/regression.at (braces parsing): New.
138 2002-01-06 Akim Demaille <akim@epita.fr>
140 Bison is dead wrong in its RR conflict reports.
142 * tests/torture.at (GNU Cim Grammar): New.
143 * src/conflicts.c (count_rr_conflicts): Fix.
145 2002-01-06 Akim Demaille <akim@epita.fr>
147 Creating package.m4 from configure.ac causes too many problems.
149 * tests/Makefile.am (package.m4): Create it by hand,
150 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
152 2002-01-04 Paul Eggert <eggert@twinsun.com>
154 * doc/bison.texinfo (Debugging):
155 Remove YYSTDERR; it's no longer defined or used.
156 Also, s/cstdio.h/cstdio/.
158 2002-01-03 Akim Demaille <akim@epita.fr>
160 * src/files.h: Add it prototype.
162 2002-01-03 Akim Demaille <akim@epita.fr>
164 * src/files.c, src/files.h (strsuffix): Not static.
165 * src/conflicts.c (conflicts_print): Don't consider it is an error
166 to have a %expectation violation on a file ending by `plural.y'.
169 2002-01-03 Akim Demaille <akim@epita.fr>
171 * tests/bison.in: Adjust to CVS Autoconf.
172 * tests/calc.at (exp): We no longer need to special case GCC as
173 the warning flags are passed by configure.
174 * tests/atlocal.in: Adjust.
175 * configure.in: Bump to 1.30j.
177 2002-01-03 Akim Demaille <akim@epita.fr>
181 2002-01-03 Akim Demaille <akim@epita.fr>
183 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
184 The ISO C++ standard is extremely clear about it: stderr is
185 considered a macro, not a regular symbol (see table 94 `Header
186 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
187 Therefore std:: does not apply to it. It still does with fprintf.
188 Also, s/cstdio.h/cstdio/.
190 2002-01-03 Akim Demaille <akim@epita.fr>
192 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
193 for non system headers.
195 2001-12-27 Paul Eggert <eggert@twinsun.com>
197 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
198 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
199 Sparc, as they were causing more porting problems than the
200 (minor) performance improvement was worth.
202 2001-12-22 Akim Demaille <akim@epita.fr>
204 * src/output.c (output_short_table, output_short_or_char_table):
205 Change the prototype to use `int' for array ranges: some
206 invocations do pass an int, not a short.
207 Reported by Wayne Green.
209 2001-12-22 Akim Demaille <akim@epita.fr>
211 Some actions of web2c.y are improperly triggered.
212 Reported by Mike Castle.
214 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
215 * tests/regression.at (Web2c): Rename as...
216 (Web2c Report): this.
217 (Web2c Actions): New.
219 2001-12-22 Akim Demaille <akim@epita.fr>
221 Reductions in web2c.y are improperly reported.
222 Reported by Mike Castle.
224 * src/conflicts.c (print_reductions): Fix.
225 * tests/regression.at (Web2c): New.
227 2001-12-18 Akim Demaille <akim@epita.fr>
231 2001-12-18 Akim Demaille <akim@epita.fr>
233 Some host fail on `assert (!"foo")', which expands to
234 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
235 Reported by Nelson Beebee.
237 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
238 `#define it_succeeded 0' and `assert (it_succeeded)'.
240 2001-12-17 Paul Eggert <eggert@twinsun.com>
242 * src/bison.simple (YYSTD): New macro.
243 (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE, YYFPRINTF, YYSTDERR): Use
244 it to simplify macros, and fix some C++ porting problems reported
247 * src/output.c (output): Define YYDEBUG to 0 if it is not defined
248 and if we are not debugging. POSIX requires this.
249 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document this.
251 * src/output.c (output_gram, output_rule_data): Do not assume that
252 the user defines YYDEBUG to a properly parenthesized expression.
254 2001-12-15 Akim Demaille <akim@epita.fr>
256 * src/nullable.c (set_nullable): Useless rules must be skipped,
257 otherwise, since we range over their symbols, we might look at a
258 nonterminal which no longer ``exists'', i.e., it is not counted in
259 `nvars', hence we overflow our arrays.
261 2001-12-15 Akim Demaille <akim@epita.fr>
263 * src/reader.c (copy_action): When --yacc, don't append a `;'
264 to the user action: let it fail if lacking.
265 Suggested by Arnold Robbins and Tom Tromey.
267 2001-12-13 Akim Demaille <akim@epita.fr>
271 2001-12-13 Akim Demaille <akim@epita.fr>
273 The computation of nullable is broken: it doesn't handle empty
276 * tests/torture.at (GNU AWK Grammar): New.
277 * tests/sets.at (Nullable): New.
278 * src/nullable.c (set_nullable): Instead of blindly looping over
279 `ritems', loop over the rules, and then over their rhs's.
281 Work around Autotest bugs.
283 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
284 frame, because Autotest understand lines starting with a `+' as
285 traces from the shell. Then, they are not processed properly.
286 Admittedly an Autotest bug, but we don't have time to wait for
287 Autotest to catch up.
288 * tests/regression.at (Broken Closure): Adjust to the new table
291 * tests/sets.at: here.
293 2001-12-12 Paul Eggert <eggert@twinsun.com>
295 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
296 Do not infringe on the global user namespace when using C++.
297 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
298 All uses of `fprintf' and `stderr' changed.
300 * src/output.c (output): Do not output "#include <stdio.h>"; that
301 is bison.simple's job. stdio.h should be included only if
302 necessary, to avoid infringing on the user name space when
305 2001-12-12 Akim Demaille <akim@epita.fr>
307 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
308 on that of lib/error.c.
310 2001-12-12 Akim Demaille <akim@epita.fr>
312 Some hosts don't like `/' in includes.
314 * src/system.h: Include libgettext.h without qualifying the path.
315 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
318 2001-12-10 Akim Demaille <akim@epita.fr>
320 Bison dumps core on bash.y.
321 Reported by Pascal Bart.
323 * src/warshall.c (bitmatrix_print): New.
325 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
326 j must be the outer loop.
327 * tests/regression.at (Broken Closure): New.
329 2001-12-05 Akim Demaille <akim@epita.fr>
333 2001-12-05 Akim Demaille <akim@epita.fr>
335 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
337 Reported by Peter Hámorský.
339 2001-12-05 Akim Demaille <akim@epita.fr>
341 * src/conflicts.c (err_table): Remove.
342 (resolve_sr_conflict): Adjust.
343 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
345 (state_t.reductions, state_t.shifts): this.
347 2001-12-05 Akim Demaille <akim@epita.fr>
349 * src/reduce.c (reduce_grammar_tables): No longer disable the
350 removal of useless rules via CPP but via `if (0)', so that the
351 compiler still check the code is valid.
352 For instance, it should have noticed `rline' no longer exists: use
353 the `line' member of rule_t.
354 * src/gram.c (dummy, rline): Remove, unused.
356 2001-12-05 Akim Demaille <akim@epita.fr>
358 * src/output.c (pack_vector): Use assert, not berror.
359 * src/main.c (berror): Remove, unused.
361 2001-12-05 Akim Demaille <akim@epita.fr>
363 New experimental feature: if --verbose --trace output all the
364 items of a state, not only its kernel.
366 * src/print.c (print_core): If `trace_flag', then invoke closure
367 before outputting the items of the state (print_core is no longer
368 a correct name them).
369 (print_results): Invoke new_closure/free_closure if needed.
371 2001-12-05 Akim Demaille <akim@epita.fr>
373 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
374 * src/closure.c, src/closure.h (itemsetsize): Rename as...
375 (nitemset): for consistency with the rest of the project.
377 2001-12-05 Akim Demaille <akim@epita.fr>
379 * src/closure.c (print_closure): Improve.
380 (closure): Use it for printing input and output.
382 2001-12-05 Akim Demaille <akim@epita.fr>
384 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
385 indexed by nonterminals.
387 2001-12-05 Akim Demaille <akim@epita.fr>
389 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
391 * src/warshall.h: Remove accidental duplication of the content.
393 2001-12-05 Akim Demaille <akim@epita.fr>
395 * src/closure.c (set_fderives): De-obfuscate.
397 2001-12-05 Akim Demaille <akim@epita.fr>

405 2001-12-05 Akim Demaille <akim@epita.fr>
407 * src/output.c (action_row): De-obfuscate
408 using the good o' techniques: arrays not pointers, variable
409 locality, BITISSET, RESETBIT etc.
411 2001-12-05 Akim Demaille <akim@epita.fr>
413 Pessimize the code to simplify it: from now on, all the states
414 have a valid SHIFTS, which NSHIFTS is possibly 0.
416 * src/LR0.c (shifts_new): Be global and move to..
417 * src/state.c, src/state.h: here.
418 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
419 * src/print_graph: Adjust.
421 2001-12-05 Akim Demaille <akim@epita.fr>
423 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
424 * src/conflicts.c: Use it.
425 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
426 incorrectly ``simplified''.
428 2001-12-05 Akim Demaille <akim@epita.fr>
430 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
431 using the good o' techniques: arrays not pointers, variable
432 locality, BITISSET, RESETBIT etc.
434 2001-12-05 Akim Demaille <akim@epita.fr>
436 * src/state.h (SHIFT_SYMBOL): New.
437 * src/conflicts.c: Use it to deobfuscate.
439 2001-12-05 Akim Demaille <akim@epita.fr>
441 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
442 (print_reductions): De-obfuscate using the good o' techniques:
443 arrays not pointers, variable locality, BITISSET.
445 2001-12-05 Akim Demaille <akim@epita.fr>
447 * src/conflicts.c (print_reductions): Arrays, not pointers.
450 2001-12-05 Akim Demaille <akim@epita.fr>
452 * src/conflicts.c (print_reductions): Pessimize, but clarify.
454 2001-12-05 Akim Demaille <akim@epita.fr>
456 * src/conflicts.c (print_reductions): Improve variable locality.
458 2001-12-05 Akim Demaille <akim@epita.fr>
460 * src/conflicts.c (print_reductions): Pessimize, but clarify.
462 2001-12-05 Akim Demaille <akim@epita.fr>
464 * src/conflicts.c (print_reductions): Improve variable locality.
466 2001-12-05 Akim Demaille <akim@epita.fr>
468 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
469 * src/lalr.c: Use them.
471 2001-12-05 Akim Demaille <akim@epita.fr>
473 * src/LR0.c (augment_automaton): Formatting changes.
474 Better variable locality.
476 2001-12-05 Akim Demaille <akim@epita.fr>
478 * src/lalr.c (matrix_print): New.
480 Use arrays instead of pointers.
482 2001-12-05 Akim Demaille <akim@epita.fr>
484 * src/lalr.c (maxrhs): Move to...
485 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
486 * src/lalr.c (build_relations): Adjust.
488 2001-12-05 Akim Demaille <akim@epita.fr>
490 * src/lalr.c (transpose): Free the memory allocated to the
491 argument, as it is replaced by the results by the unique caller.
492 (build_relations): Merely invoke transpose: it handles the memory
494 Improve variable locality.
495 Avoid variables used as mere abbreviations.
496 (compute_lookaheads): Use arrays instead of pointers.
498 2001-12-05 Akim Demaille <akim@epita.fr>
500 * src/lalr.c (initialize_F): Improve variable locality.
501 Avoid variables used as mere abbreviations.
503 2001-12-05 Akim Demaille <akim@epita.fr>
505 * src/derives.c (print_derives): Display the ruleno.
506 * src/lalr.c (initialize_F, transpose): Better variable locality
507 to improve readability.
508 Avoid variables used as mere abbreviations.
510 2001-12-05 Akim Demaille <akim@epita.fr>
512 * src/lalr.c (traverse): Use arrays instead of pointers.
514 2001-12-05 Akim Demaille <akim@epita.fr>
516 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
517 the handling of squeue.
518 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
520 2001-12-05 Akim Demaille <akim@epita.fr>
522 Because useless nonterminals are now kept alive (instead of being
523 `destroyed'), we now sometimes examine them, and store information
524 related to them. Hence we need to know their number, and adjust
527 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
529 * src/LR0.c (allocate_itemsets): The memory allocated to
530 `symbol_count' was used for two different purpose: once to count
531 the number of occurrences of each symbol, and later reassigned to
532 `shift_symbol', containing the symbol that can be shifted from a
534 Deobfuscate, i.e., allocate, use and free `symbol_count' here
536 (new_itemsets): Allocate `shift_symbol' here.
537 (allocate_itemsets): symbol_count includes useless nonterminals.
539 (free_storage): Use `free', not `XFREE', for pointers that cannot
542 2001-12-05 Akim Demaille <akim@epita.fr>
544 * src/nullable.c (set_nullable): Deobfuscate the handling of
546 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
548 2001-12-05 Akim Demaille <akim@epita.fr>
550 * src/gram.c, src/gram.h (ritem_print): New.
551 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
552 (This useless function was defined only to work around VMS linkers
553 that can't handle compilation units with variables only).
554 * src/reduce.c (dump_grammar): Use it to trace the construction of
557 2001-12-04 Paul Eggert <eggert@twinsun.com>
559 * src/bison.simple (union yyalloc): Change member names
560 to be the same as the stack names.
561 (yyparse): yyptr is now union yyalloc *, not char *.
562 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
563 and may generate better code on some machines.
564 (yystpcpy): Use prototype if __STDC__ is defined, not just
565 if __cplusplus is defined.
567 2001-11-30 Akim Demaille <akim@epita.fr>
569 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
570 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
571 Gettext doesn't compile cleanly, and dies with -Werror.
572 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
573 Include WARNING_CFLAGS here.
574 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
575 before being defined.
577 2001-11-30 Paul Eggert <eggert@twinsun.com>
579 * lib/quotearg.h (quotearg_n, quotearg_n_style):
580 First arg is int, not unsigned.
581 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
582 (SIZE_MAX, UINT_MAX): New macros.
583 (quotearg_n_options): Abort if N is negative.

601 on user names when possible.
603 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
604 Simplify test for whather <alloca.h> exists.
606 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
608 (<stdio.h>): Include if YYDEBUG.
610 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
611 ! defined (yyoverflow) && ! defined (yymemcpy).
613 (yymemcpy, yyparse): Rename local variables as needed so that
614 they all begin with 'yy'.
616 (yystrlen, yystpcpy): New functions.
618 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
621 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
622 instead of relying on string.h functions. Use YYSTACK_ALLOC
623 and YYSTACK_FREE instead of malloc and free.

627 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
628 if body instead of `;' to pacify GCC's warnings.
630 2001-11-30 Akim Demaille <akim@epita.fr>
632 Instead of mapping the LHS of unused rules to -1, keep the LHS
633 valid, but flag the rules as invalid.

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

2257 prevents type checking.
2258 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
2259 cast the value to (void *): assigning a `foo *' to a `void *'

2270 * tests/atgeneral.m4: Update from CVS Autoconf.
2272 2000-11-17 Akim Demaille <akim@epita.fr>
2274 * tests/regression.m4 (%union and --defines): New test,
2275 demonstrating a current bug in the obstack implementation.

2306 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
2307 argument `data' for consistency with the prototypes.
2309 (obstack_copy, obstack_copy0): Rename the second argument as
2310 `address' for consistency. Qualify it `const'.
2311 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)

2339 (done): Rename as...
2340 (output_files): this.
2342 * src/main.c (main): Don't use `atexit' to register `done', since
2343 it no longer has to remove tmp files, just call `output_files'
2344 when there are no errors.
2346 2000-11-02 Akim Demaille <akim@epita.fr>
2348 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
2349 `unlink': it's no longer used.

2415 * src/reader.c (copy_comment2): Expect the input stream to be on
2416 the `/' which is suspected to open a comment, instead of being
2417 called after `//' or `/*' was read.
2418 (copy_comment, copy_definition, parse_union_decl, copy_action)
2419 (copy_guard): Adjust.
2421 2000-10-16 Akim Demaille <akim@epita.fr>

2445 * doc/bison.texinfo: Various typos spotted by Neil Booth.
2447 2000-10-04 Akim Demaille <akim@epita.fr>
2449 When a literal string is used to define two different tokens,
2450 `bison -v' segfaults.
2451 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
2453 * tests/regression.m4: New file.
2454 Include the core of the sample provided by Piotr Gackiewicz.
2455 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed

2478 translation, move some `\n' out of the translated strings.
2480 2000-10-02 Akim Demaille <akim@epita.fr>
2482 The location tracking mechanism is precious for parse error
2483 messages. Nevertheless, it is enabled only when `@n' is used in
2484 the grammar, which is a different issue (you can use it in error
2485 message, but not in the grammar per se). Therefore, there should
2486 be another means to enable it.
2488 * src/getargs.c (getargs): Support `--locations'.
2490 * src/getargs.h (locationsflag): Export it.
2491 * src/lex.c (percent_table): Support `%locations'.

2493 with `locationsflag'.

2496 * tests/calc.m4: Test it.
2498 For regularity of the names, replace each
2499 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
2500 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
2501 In addition replace each `flag' with `_flag'.
2503 2000-10-02 Akim Demaille <akim@epita.fr>
2505 Also test parse error messages, including with YYERROR_VERBOSE.
2507 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
2509 Use it to check the computations.
2510 Use it to check `nonassoc' is honored.
2511 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
2512 `--yyerror-verbose'.

2514 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
2516 2000-10-02 Akim Demaille <akim@epita.fr>
2518 Test also `--verbose', `--defines' and `--name-prefix'. Testing
2519 the latter demonstrates a flaw in the handling of non debugging
2520 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
2521 was used in order to simplify:
2537 unfortunately this leads to a CPP conflict when
2538 `--name-prefix=foo' is used since it produces `#define yydebug
2541 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
2542 (YYDPRINTF): New macro.
2544 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
2546 Also test `--verbose', `--defines' and `--name-prefix'.
2548 2000-10-02 Akim Demaille <akim@epita.fr>
2550 Improve the readability of the produced parsers.
2552 * src/bison.s1: Formatting changes.
2553 Improve the comment related to the `$' mark.
2554 (yydefault): Don't fall through to `yyresume': `goto' there.
2555 * src/output.c (output_parser): When the `$' is met, skip the end
2557 New variable, `number_of_dollar_signs', to check there's exactly
2558 one `$' in the parser skeleton.
2560 2000-10-02 Akim Demaille <akim@epita.fr>
2562 * lib/xstrdup.c: New file, from the fileutils.
2563 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
2564 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
2565 instead of strlen + xmalloc + strcpy.
2566 * src/symtab.c (copys): Remove, use xstrdup instead.
2568 2000-10-02 Akim Demaille <akim@epita.fr>
2570 * src/gram.h (associativity): New enum type which replaces the
2571 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
2572 `right_assoc', `left_assoc' and `non_assoc'.
2573 Adjust all dependencies.
2574 * src/reader.c: Formatting changes.
2575 (LTYPESTR): Don't define it, use it as a literal in
2576 `reader_output_yylsp'.
2577 * src/symtab.h (symbol_class): New enum type which replaces the
2578 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
2579 `sunknown', `stoken and `snterm'.
2581 2000-10-02 Akim Demaille <akim@epita.fr>
2583 * src/getargs.c (fixed_outfiles): Rename as...
2584 (yaccflag): for consistency and accuracy.
2585 Adjust dependencies.
2587 2000-10-02 Akim Demaille <akim@epita.fr>
2589 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
2590 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
2591 difficult and introduced a lot of core dump. It turns out that
2592 Bison used an implementation of `xmalloc' based on `calloc', and
2593 at various places it does depend upon the initialization to 0. I
2594 have not tried to isolate the pertinent places, and all the former
2595 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
2596 someone should address this issue.
2598 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.

2697 2000-10-02 Akim Demaille <akim@epita.fr>
2699 `user_toknums' is output as a `short[]' in `output.c', while it is
2700 defined as a `int[]' in `reader.c'. For consistency with the
2701 other output tables, `user_toknums' is now defined as a table of
2704 * src/reader.c (user_toknums): Be a short table instead of an int
2706 Adjust dependencies.
2708 Factor the short table outputs.

2744 Don't define PARAMS.
2745 * src/system.h: Define PARAMS.
2746 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
2747 purpose of config.h. system.h must not try to fix wrong

3005 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

3697 (read_declarations): Improve the error message for
3698 an invalid character. Do not abort.
3699 (read_declarations, copy_guard, copy_action): Use
3700 printable_version to avoid unprintable characters in printed output.

3730 buffer while reading an integer.
3731 (parse_percent_token): Replaced if-else statement with percent_table.
3732 (parse_percent_token): Added % declarations as another
3733 way to specify the flags -n, -l, and -r. Also added hooks for
3734 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
3735 major changes to files.c.
3736 (lex) Retain in the incoming stream a character following
3738 (skip_white_space, lex): Revised most error messages
3739 and changed fatal to warn to avoid aborting.
