ChangeLog

   1 2001-12-18  Akim Demaille  <akim@epita.fr>
   2
   3         Some host fail on `assert (!"foo")', which expands to
   4         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
   5         Reported by Nelson Beebee.
   6
   7         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
   8         `#define it_succeeded 0' and `assert (it_succeeded)'.
   9
  10 2001-12-17  Paul Eggert  <eggert@twinsun.com>
  11
  12         * src/bison.simple (YYSTD): New macro.
  13         (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE, YYFPRINTF, YYSTDERR): Use
  14         it to simplify macros, and fix some C++ porting problems reported
  15         by Hans Aberg.
  16
  17         * src/output.c (output): Define YYDEBUG to 0 if it is not defined
  18         and if we are not debugging.  POSIX requires this.
  19         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document this.
  20
  21         * src/output.c (output_gram, output_rule_data): Do not assume that
  22         the user defines YYDEBUG to a properly parenthesized expression.
  23
  24 2001-12-15  Akim Demaille  <akim@epita.fr>
  25
  26         * src/nullable.c (set_nullable): Useless rules must be skipped,
  27         otherwise, since we range over their symbols, we might look at a
  28         nonterminal which no longer ``exists'', i.e., it is not counted in
  29         `nvars', hence we overflow our arrays.
  30
  31 2001-12-15  Akim Demaille  <akim@epita.fr>
  32
  33         * src/reader.c (copy_action): When --yacc, don't append a `;'
  34         to the user action: let it fail if lacking.
  35         Suggested by Aharon Robbins and Tom Tromey.
  36
  37 2001-12-13  Akim Demaille  <akim@epita.fr>
  38
  39         Version 1.30g.
  40
  41 2001-12-13  Akim Demaille  <akim@epita.fr>
  42
  43         The computation of nullable is broken: it doesn't handle empty
  44         RHS's properly.
  45
  46         * tests/torture.at (GNU AWK Grammar): New.
  47         * tests/sets.at (Nullable): New.
  48         * src/nullable.c (set_nullable): Instead of blindly looping over
  49         `ritems', loop over the rules, and then over their rhs's.
  50
  51         Work around Autotest bugs.
  52
  53         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
  54         frame, because Autotest understand lines starting with a `+' as
  55         traces from the shell.  Then, they are not processed properly.
  56         Admittedly an Autotest bug, but we don't have time to wait for
  57         Autotest to catch up.
  58         * tests/regression.at (Broken Closure): Adjust to the new table
  59         frames.
  60         Move to...
  61         * tests/sets.at: here.
  62
  63 2001-12-12  Paul Eggert  <eggert@twinsun.com>
  64
  65         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
  66         Do not infringe on the global user namespace when using C++.
  67         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
  68         All uses of `fprintf' and `stderr' changed.
  69
  70         * src/output.c (output): Do not output "#include <stdio.h>"; that
  71         is bison.simple's job.  stdio.h should be included only if
  72         necessary, to avoid infringing on the user name space when
  73         possible.
  74
  75 2001-12-12  Akim Demaille  <akim@epita.fr>
  76
  77         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
  78         on that of lib/error.c.
  79
  80 2001-12-12  Akim Demaille  <akim@epita.fr>
  81
  82         Some hosts don't like `/' in includes.
  83
  84         * src/system.h: Include libgettext.h without qualifying the path.
  85         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
  86         $(top_srcdir).
  87
  88 2001-12-10  Akim Demaille  <akim@epita.fr>
  89
  90         Bison dumps core on bash.y.
  91         Reported by Pascal Bart.
  92
  93         * src/warshall.c (bitmatrix_print): New.
  94         (TC): Use it.
  95         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
  96         j must be the outer loop.
  97         * tests/regression.at (Broken Closure): New.
  98
  99 2001-12-05  Akim Demaille  <akim@epita.fr>
 100
 101         Version 1.30f.
 102
 103 2001-12-05  Akim Demaille  <akim@epita.fr>
 104
 105         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
 106         its argument.
 107         Reported by Peter Hámorský.
 108
 109 2001-12-05  Akim Demaille  <akim@epita.fr>
 110
 111         * src/conflicts.c (err_table): Remove.
 112         (resolve_sr_conflict): Adjust.
 113         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
 114         Rename as...
 115         (state_t.reductions, state_t.shifts): this.
 116
 117 2001-12-05  Akim Demaille  <akim@epita.fr>
 118
 119         * src/reduce.c (reduce_grammar_tables): No longer disable the
 120         removal of useless rules via CPP but via `if (0)', so that the
 121         compiler still check the code is valid.
 122         For instance, it should have noticed `rline' no longer exists: use
 123         the `line' member of rule_t.
 124         * src/gram.c (dummy, rline): Remove, unused.
 125
 126 2001-12-05  Akim Demaille  <akim@epita.fr>
 127
 128         * src/output.c (pack_vector): Use assert, not berror.
 129         * src/main.c (berror): Remove, unused.
 130
 131 2001-12-05  Akim Demaille  <akim@epita.fr>
 132
 133         New experimental feature: if --verbose --trace output all the
 134         items of a state, not only its kernel.
 135
 136         * src/print.c (print_core): If `trace_flag', then invoke closure
 137         before outputting the items of the state (print_core is no longer
 138         a correct name them).
 139         (print_results): Invoke new_closure/free_closure if needed.
 140
 141 2001-12-05  Akim Demaille  <akim@epita.fr>
 142
 143         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
 144         * src/closure.c, src/closure.h (itemsetsize): Rename as...
 145         (nitemset): for consistency with the rest of the project.
 146
 147 2001-12-05  Akim Demaille  <akim@epita.fr>
 148
 149         * src/closure.c (print_closure): Improve.
 150         (closure): Use it for printing input and output.
 151
 152 2001-12-05  Akim Demaille  <akim@epita.fr>
 153
 154         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
 155         indexed by nonterminals.
 156
 157 2001-12-05  Akim Demaille  <akim@epita.fr>
 158
 159         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
 160         what it was!).
 161         * src/warshall.h: Remove accidental duplication of the content.
 162
 163 2001-12-05  Akim Demaille  <akim@epita.fr>
 164
 165         * src/closure.c (set_fderives): De-obfuscate.
 166
 167 2001-12-05  Akim Demaille  <akim@epita.fr>
 168
 169         * src/closure.c (print_firsts, print_fderives): De-obfuscate.
 170
 171 2001-12-05  Akim Demaille  <akim@epita.fr>
 172
 173         * src/closure.c (set_firsts): De-obfuscate.
 174
 175 2001-12-05  Akim Demaille  <akim@epita.fr>
 176
 177         * src/output.c (action_row): De-obfuscate
 178         using the good o' techniques: arrays not pointers, variable
 179         locality, BITISSET, RESETBIT etc.
 180
 181 2001-12-05  Akim Demaille  <akim@epita.fr>
 182
 183         Pessimize the code to simplify it: from now on, all the states
 184         have a valid SHIFTS, which NSHIFTS is possibly 0.
 185
 186         * src/LR0.c (shifts_new): Be global and move to..
 187         * src/state.c, src/state.h: here.
 188         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
 189         * src/print_graph: Adjust.
 190
 191 2001-12-05  Akim Demaille  <akim@epita.fr>
 192
 193         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
 194         * src/conflicts.c: Use it.
 195         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
 196         incorrectly ``simplified''.
 197
 198 2001-12-05  Akim Demaille  <akim@epita.fr>
 199
 200         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
 201         using the good o' techniques: arrays not pointers, variable
 202         locality, BITISSET, RESETBIT etc.
 203
 204 2001-12-05  Akim Demaille  <akim@epita.fr>
 205
 206         * src/state.h (SHIFT_SYMBOL): New.
 207         * src/conflicts.c: Use it to deobfuscate.
 208
 209 2001-12-05  Akim Demaille  <akim@epita.fr>
 210
 211         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
 212         (print_reductions): De-obfuscate using the good o' techniques:
 213         arrays not pointers, variable locality, BITISSET.
 214
 215 2001-12-05  Akim Demaille  <akim@epita.fr>
 216
 217         * src/conflicts.c (print_reductions): Arrays, not pointers.
 218         Use BITISSET.
 219
 220 2001-12-05  Akim Demaille  <akim@epita.fr>
 221
 222         * src/conflicts.c (print_reductions): Pessimize, but clarify.
 223
 224 2001-12-05  Akim Demaille  <akim@epita.fr>
 225
 226         * src/conflicts.c (print_reductions): Improve variable locality.
 227
 228 2001-12-05  Akim Demaille  <akim@epita.fr>
 229
 230         * src/conflicts.c (print_reductions): Pessimize, but clarify.
 231
 232 2001-12-05  Akim Demaille  <akim@epita.fr>
 233
 234         * src/conflicts.c (print_reductions): Improve variable locality.
 235
 236 2001-12-05  Akim Demaille  <akim@epita.fr>
 237
 238         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
 239         * src/lalr.c: Use them.
 240
 241 2001-12-05  Akim Demaille  <akim@epita.fr>
 242
 243         * src/LR0.c (augment_automaton): Formatting changes.
 244         Better variable locality.
 245
 246 2001-12-05  Akim Demaille  <akim@epita.fr>
 247
 248         * src/lalr.c (matrix_print): New.
 249         (transpose): Use it.
 250         Use arrays instead of pointers.
 251
 252 2001-12-05  Akim Demaille  <akim@epita.fr>
 253
 254         * src/lalr.c (maxrhs): Move to...
 255         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
 256         * src/lalr.c (build_relations): Adjust.
 257
 258 2001-12-05  Akim Demaille  <akim@epita.fr>
 259
 260         * src/lalr.c (transpose): Free the memory allocated to the
 261         argument, as it is replaced by the results by the unique caller.
 262         (build_relations): Merely invoke transpose: it handles the memory
 263         deallocation.
 264         Improve variable locality.
 265         Avoid variables used as mere abbreviations.
 266         (compute_lookaheads): Use arrays instead of pointers.
 267
 268 2001-12-05  Akim Demaille  <akim@epita.fr>
 269
 270         * src/lalr.c (initialize_F): Improve variable locality.
 271         Avoid variables used as mere abbreviations.
 272
 273 2001-12-05  Akim Demaille  <akim@epita.fr>
 274
 275         * src/derives.c (print_derives): Display the ruleno.
 276         * src/lalr.c (initialize_F, transpose): Better variable locality
 277         to improve readability.
 278         Avoid variables used as mere abbreviations.
 279
 280 2001-12-05  Akim Demaille  <akim@epita.fr>
 281
 282         * src/lalr.c (traverse): Use arrays instead of pointers.
 283
 284 2001-12-05  Akim Demaille  <akim@epita.fr>
 285
 286         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
 287         the handling of squeue.
 288         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
 289
 290 2001-12-05  Akim Demaille  <akim@epita.fr>
 291
 292         Because useless nonterminals are now kept alive (instead of being
 293         `destroyed'), we now sometimes examine them, and store information
 294         related to them.  Hence we need to know their number, and adjust
 295         memory allocations.
 296
 297         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
 298         static.
 299         * src/LR0.c (allocate_itemsets): The memory allocated to
 300         `symbol_count' was used for two different purpose: once to count
 301         the number of occurrences of each symbol, and later reassigned to
 302         `shift_symbol', containing the symbol that can be shifted from a
 303         given state.
 304         Deobfuscate, i.e., allocate, use and free `symbol_count' here
 305         only, and...
 306         (new_itemsets): Allocate `shift_symbol' here.
 307         (allocate_itemsets): symbol_count includes useless nonterminals.
 308         Make room for them.
 309         (free_storage): Use `free', not `XFREE', for pointers that cannot
 310         be null.
 311
 312 2001-12-05  Akim Demaille  <akim@epita.fr>
 313
 314         * src/nullable.c (set_nullable): Deobfuscate the handling of
 315         ritem.
 316         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
 317
 318 2001-12-05  Akim Demaille  <akim@epita.fr>
 319
 320         * src/gram.c, src/gram.h (ritem_print): New.
 321         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
 322         (This useless function was defined only to work around VMS linkers
 323         that can't handle compilation units with variables only).
 324         * src/reduce.c (dump_grammar): Use it to trace the construction of
 325         ritem.
 326
 327 2001-12-04  Paul Eggert  <eggert@twinsun.com>
 328
 329         * src/bison.simple (union yyalloc): Change member names
 330         to be the same as the stack names.
 331         (yyparse): yyptr is now union yyalloc *, not char *.
 332         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
 333         and may generate better code on some machines.
 334         (yystpcpy): Use prototype if __STDC__ is defined, not just
 335         if __cplusplus is defined.
 336
 337 2001-11-30  Akim Demaille  <akim@epita.fr>
 338
 339         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
 340         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
 341         Gettext doesn't compile cleanly, and dies with -Werror.
 342         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
 343         Include WARNING_CFLAGS here.
 344         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
 345         before being defined.
 346
 347 2001-11-30  Paul Eggert  <eggert@twinsun.com>
 348
 349         * lib/quotearg.h (quotearg_n, quotearg_n_style):
 350         First arg is int, not unsigned.
 351         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
 352         (SIZE_MAX, UINT_MAX): New macros.
 353         (quotearg_n_options): Abort if N is negative.
 354         Avoid overflow check on hosts where size_t is 64 bits and int
 355         is 32 bits, as overflow is impossible there.
 356         Fix off-by-one typo that caused unnecessary reallocation.
 357
 358 2001-11-30  Paul Eggert  <eggert@twinsun.com>
 359
 360         Name space cleanup in generated parser.
 361
 362         * doc/bison.texinfo (Bison Parser): Discuss system headers
 363         and their effect on the user name space.
 364
 365         * src/bison.simple:
 366         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
 367         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
 368         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
 369
 370         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
 371         on user names when possible.
 372
 373         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
 374         Simplify test for whather <alloca.h> exists.
 375
 376         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
 377
 378         (<stdio.h>): Include if YYDEBUG.
 379

 382
 383         (yymemcpy, yyparse): Rename local variables as needed so that

 396
 397         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty

 399
 400 2001-11-30  Akim Demaille  <akim@epita.fr>
 401
 402         Instead of mapping the LHS of unused rules to -1, keep the LHS

 404
 405         * src/gram.h (rule_t): `useful' is a new member.

 420
 421         * src/reduce.c (nonterminals_reduce): Instead of throwing away
 422         useless nonterminals, move them at the end of the symbol arrays.

 438         New macros.
 439         (union yyalloc): New type.
 440         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
 441         an arbitrary restriction on hosts where size_t is wider than int.
 442
 443         (yyparse): Don't dump core if alloca or malloc fails; instead, report
 444         a parser stack overflow.  Allocate just one block of memory for all
 445         three stacks, instead of allocating three blocks; this typically is
 446         faster and reduces fragmentation.
 447
 448         Do not limit the number of items in the stack to a value that fits
 449         in 'int', as this is an arbitrary limit on hosts with 64-bit
 450         size_t and 32-bit int.
 451
 452 2001-11-28  Akim Demaille  <akim@epita.fr>

 463
 464         * src/closure.c (closure): Instead of looping over word in array

 468
 469         * src/closure.c (closure): No longer optimize the special case
 470         where all the bits of `ruleset[r]' are set to 0, to make the code
 471         clearer.

 473 2001-11-28  Akim Demaille  <akim@epita.fr>
 474
 475         * src/closure.c (closure): `r' and `c' are new variables, used to

 490         * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
 491         as all tags are free'ed afterwards.

 576 2001-11-23  Akim Demaille  <akim@epita.fr>
 577
 578         Attaching lineno to buckets is stupid, since only one copy of each

 967         Add description of `%name-prefix', `file-prefix', and `output'.
 968         Promote `-' over `_' in directive names.
 969         (Bison Options): s/%locactions/%locations/.  Nice Freudian slip.
 970         Simplify the description of `--name-prefix'.
 971         Promote `-' over `_' in directive names.
 972         Promote `--output' over `--output-file'.

1917

2026         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it

2028         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
2029         cast the value to (void *): assigning a `foo *' to a `void *'

2219         When a literal string is used to define two different tokens,
2220         `bison -v' segfaults.
2221         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
2222
2223         * tests/regression.m4: New file.
2224         Include the core of the sample provided by Piotr Gackiewicz.
2225         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
2226         properly.

2229
2230         * src/reader.c (parse_expect_decl): Keep `count' within the size
2231         of `buffer'.

2234 2000-10-02  Paul Eggert  <eggert@twinsun.com>
2235
2236         * bison.s1 (yyparse): Assign the default value
2237         unconditionally, to avoid a GCC warning and make the parser a
2238         tad smaller.
2239
2240 2000-10-02  Akim Demaille  <akim@epita.fr>
2241
2242         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
2243         options.
2244
2245 2000-10-02  Akim Demaille  <akim@epita.fr>
2246
2247         * src/derives.c, src/print.c, src/reduce.c: To ease the
2248         translation, move some `\n' out of the translated strings.
2249
2250 2000-10-02  Akim Demaille  <akim@epita.fr>
2251
2252         The location tracking mechanism is precious for parse error
2253         messages.  Nevertheless, it is enabled only when `@n' is used in
2254         the grammar, which is a different issue (you can use it in error
2255         message, but not in the grammar per se).  Therefore, there should
2256         be another means to enable it.
2257
2258         * src/getargs.c (getargs): Support `--locations'.
2259         (usage): Report it.
2260         * src/getargs.h (locationsflag): Export it.
2261         * src/lex.c (percent_table): Support `%locations'.
2262         * src/reader.c (yylsp_needed): Remove this variable, now replaced
2263         with `locationsflag'.
2264         * doc/bison.texinfo: Document `--locations' and `%locations'.
2265         Sort the options.
2266         * tests/calc.m4: Test it.
2267
2268         For regularity of the names, replace each
2269         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
2270         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
2271         In addition replace each `flag' with `_flag'.
2272
2273 2000-10-02  Akim Demaille  <akim@epita.fr>
2274
2275         Also test parse error messages, including with YYERROR_VERBOSE.
2276
2277         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
2278         associative).
2279         Use it to check the computations.
2280         Use it to check `nonassoc' is honored.
2281         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
2282         `--yyerror-verbose'.
2283         (_AT_CHECK_CALC): Adjust to this option.
2284         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
2285
2286 2000-10-02  Akim Demaille  <akim@epita.fr>
2287
2288         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
2289         the latter demonstrates a flaw in the handling of non debugging
2290         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
2291         was used in order to simplify:
2292
2293         #if YYDEBUG
2294         if (yydebug)
2295         {
2296         ...
2297         }
2298         #endif
2299
2300         into
2301
2302         if (yydebug)
2303         {
2304         ...
2305         }
2306
2307         unfortunately this leads to a CPP conflict when
2308         `--name-prefix=foo' is used since it produces `#define yydebug
2309         foodebug'.
2310
2311         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
2312         (YYDPRINTF): New macro.
2313         Spread its use.
2314         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
2315         the bison options.
2316         Also test `--verbose', `--defines' and `--name-prefix'.
2317
2318 2000-10-02  Akim Demaille  <akim@epita.fr>
2319
2320         Improve the readability of the produced parsers.
2321
2322         * src/bison.s1: Formatting changes.
2323         Improve the comment related to the `$' mark.
2324         (yydefault): Don't fall through to `yyresume': `goto' there.
2325         * src/output.c (output_parser): When the `$' is met, skip the end
2326         of its line.
2327         New variable, `number_of_dollar_signs', to check there's exactly
2328         one `$' in the parser skeleton.
2329
2330 2000-10-02  Akim Demaille  <akim@epita.fr>
2331
2332         * lib/xstrdup.c: New file, from the fileutils.
2333         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
2334         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
2335         instead of strlen + xmalloc + strcpy.
2336         * src/symtab.c (copys): Remove, use xstrdup instead.
2337
2338 2000-10-02  Akim Demaille  <akim@epita.fr>
2339
2340         * src/gram.h (associativity): New enum type which replaces the
2341         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
2342         `right_assoc', `left_assoc' and `non_assoc'.
2343         Adjust all dependencies.
2344         * src/reader.c: Formatting changes.
2345         (LTYPESTR): Don't define it, use it as a literal in
2346         `reader_output_yylsp'.
2347         * src/symtab.h (symbol_class): New enum type which replaces the
2348         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
2349         `sunknown', `stoken and `snterm'.
2350
2351 2000-10-02  Akim Demaille  <akim@epita.fr>
2352
2353         * src/getargs.c (fixed_outfiles): Rename as...
2354         (yaccflag): for consistency and accuracy.
2355         Adjust dependencies.
2356
2357 2000-10-02  Akim Demaille  <akim@epita.fr>
2358
2359         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
2360         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
2361         difficult and introduced a lot of core dump.  It turns out that
2362         Bison used an implementation of `xmalloc' based on `calloc', and
2363         at various places it does depend upon the initialization to 0.  I
2364         have not tried to isolate the pertinent places, and all the former
2365         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
2366         someone should address this issue.
2367
2368         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
2369         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
2370         files.
2371         Adjust dependencies.
2372         * src/warshall.h: New file.
2373         Propagate.

2375 2000-10-02  Akim Demaille  <akim@epita.fr>
2376
2377         Various anti-`extern in *.c' changes.
2378
2379         * src/system.h: Include `assert.h'.
2380
2381 2000-10-02  Akim Demaille  <akim@epita.fr>
2382
2383         * src/state.h (nstates, final_state, first_state, first_shift)
2384         (first_reduction): Move their exportation from here...
2385         * src/LR0.h: to here.
2386         Adjust dependencies.
2387         * src/getargs.c (statisticsflag): New variable.
2388         Add support for `--statistics'.

2460
2461 2000-10-02  Akim Demaille  <akim@epita.fr>
2462
2463         * src/output.c (token_actions): Introduce a temporary array,
2464         YYDEFACT, that makes it possible for this function to use
2465         output_short_table.
2466
2467 2000-10-02  Akim Demaille  <akim@epita.fr>
2468
2469         `user_toknums' is output as a `short[]' in `output.c', while it is
2470         defined as a `int[]' in `reader.c'.  For consistency with the
2471         other output tables, `user_toknums' is now defined as a table of
2472         shorts.
2473
2474         * src/reader.c (user_toknums): Be a short table instead of an int
2475         table.

2485
2486         * src/output.c (output): Topological sort of the functions, in
2487         order to get rid of the `static' prototypes.
2488         No longer use `register'.
2489         * src/output.h: New file.
2490         Propagate its inclusion in files explicitly prototyping functions
2491         from output.c.

2500         * src/closure.c: Formatting changes, topological sort over the
2501         functions, use of closure.h.
2502         (initialize_closure, finalize_closure):  Rename as...
2503         (new_closure, free_closure): these.  Adjust dependencies.

2513         inclusion.
2514         Don't define PARAMS.
2515         * src/system.h: Define PARAMS.
2516         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
2517         purpose of config.h.  system.h must not try to fix wrong
2518         definitions in config.h.

2542         * src/getargs.h: New file.
2543         Let all `extern' declarations about getargs.c be replaced with

2558
2559         * configure.in: Append WARNING_CFLAGS to CFLAGS.

2572

2680         the file name, not the whole `#line LINE FILE'.
2681
2682 2000-03-17  Akim Demaille  <akim@epita.fr>
2683
2684         On syntax errors, report the token on which we choked.
2685
2686         * src/bison.s1 (yyparse): In the label yyerrlab, when

2706         copy_comment.  Removed now unused `match', `ended',
2707         `cplus_comment'.
2708         (copy_comment, copy_string): Moved, to be visible from
2709         copy_definition.

2712

2735
2736         Change the handling of @s so that they behave exactly like $s.
2737         There is now a pseudo variable @$ (readble and writable), location
2738         of the lhs of the rule (by default ranging from the location of
2739         the first symbol of the rhs, to the location of the last symbol,
2740         or, if the rhs is empty, YYLLOC).
2741
2742         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2743         yyval.
2744         (yyparse): When providing a default semantic action, provide a
2745         default location action.
2746         (after the $): No longer change `*YYLSP', just stack YYLOC the
2747         same way you stack YYVAL.
2748         * src/reader.c (read_declarations): Use warns.
2749         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2750         (copy_action, case '@'): Likewise.
2751         Use a standard error message, to save useless work from
2752         translators.
2753
2754 2000-03-17  Akim Demaille  <akim@epita.fr>
2755

2773
2774         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
2775         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2776         One `#if YYDEBUG' remains, since it uses variables which are
2777         defined only if `YYDEBUG != 0'.
2778
2779 2000-03-16  Akim Demaille  <akim@epita.fr>

2805         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

2811         the proper line number and file name.
2812         (DEFS): Propagate the location of bison library files and of the
2813         locale files.
2814         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
2815         builddir.
2816         * acinclude.m4: Remove, replaced by the directory m4.
2817         * m4/Makefile.am (EXTRA_DIST): New variable.
2818         * m4/gettext.m4: New file, from the fileutils.

3505         major changes to files.c.
3506         (lex) Retain in the incoming stream a character following
3507         an incorrect '/'.
