   5
   6
   7 2001-12-05  Akim Demaille  <akim@epita.fr>
   8
   9         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
  10         indexed by nonterminals.
  11
  12
  13 2001-12-05  Akim Demaille  <akim@epita.fr>
  14
  15         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
  16         what it was!).
  17         * src/warshall.h: Remove accidental duplication of the content.
  18
  19

  31
  32         * src/closure.c (set_firsts): De-obfuscate.
  33
  34 2001-12-05  Akim Demaille  <akim@epita.fr>
  35
  36         * src/output.c (action_row): De-obfuscate
  37         using the good o' techniques: arrays not pointers, variable
  38         locality, BITISSET, RESETBIT etc.
  39
  40
  41 2001-12-05  Akim Demaille  <akim@epita.fr>
  42
  43         Pessimize the code to simplify it: from now on, all the states
  44         have a valid SHIFTS, which NSHIFTS is possibly 0.
  45
  46         * src/LR0.c (shifts_new): Be global and move to..
  47         * src/state.c, src/state.h: here.
  48         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
  49         * src/print_graph: Adjust.
  50
  51
  52 2001-12-05  Akim Demaille  <akim@epita.fr>
  53
  54         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
  55         * src/conflicts.c: Use it.
  56         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
  57         incorrectly ``simplified''.
  58
  59
  60 2001-12-05  Akim Demaille  <akim@epita.fr>
  61
  62         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
  63         using the good o' techniques: arrays not pointers, variable
  64         locality, BITISSET, RESETBIT etc.
  65
  66
  67 2001-12-05  Akim Demaille  <akim@epita.fr>
  68
  69         * src/state.h (SHIFT_SYMBOL): New.
  70         * src/conflicts.c: Use it to deobfuscate.
  71
  72
  73 2001-12-05  Akim Demaille  <akim@epita.fr>
  74
  75         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
  76         (print_reductions): De-obfuscate using the good o' techniques:
  77         arrays not pointers, variable locality, BITISSET.
  78
  79
  80 2001-12-05  Akim Demaille  <akim@epita.fr>
  81
  82         * src/conflicts.c (print_reductions): Arrays, not pointers.
  83         Use BITISSET.
  84
  85
  86 2001-12-05  Akim Demaille  <akim@epita.fr>
  87
  88         * src/conflicts.c (print_reductions): Pessimize, but clarify.
  89
  90
  91 2001-12-05  Akim Demaille  <akim@epita.fr>
  92
  93         * src/conflicts.c (print_reductions): Improve variable locality.
  94
  95
  96 2001-12-05  Akim Demaille  <akim@epita.fr>
  97
  98         * src/conflicts.c (print_reductions): Pessimize, but clarify.
  99
 100
 101 2001-12-05  Akim Demaille  <akim@epita.fr>
 102
 103         * src/conflicts.c (print_reductions): Improve variable locality.
 104
 105
 106 2001-12-05  Akim Demaille  <akim@epita.fr>
 107
 108         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
 109         * src/lalr.c: Use them.
 110
 111
 112 2001-12-05  Akim Demaille  <akim@epita.fr>
 113
 114         * src/LR0.c (augment_automaton): Formatting changes.
 115         Better variable locality.
 116
 117
 118 2001-12-05  Akim Demaille  <akim@epita.fr>
 119
 120         * src/lalr.c (matrix_print): New.
 121         (transpose): Use it.
 122         Use arrays instead of pointers.
 123
 124 2001-12-05  Akim Demaille  <akim@epita.fr>
 125
 126         * src/lalr.c (maxrhs): Move to...
 127         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
 128         * src/lalr.c (build_relations): Adjust.
 129
 130 2001-12-05  Akim Demaille  <akim@epita.fr>
 131
 132         * src/lalr.c (transpose): Free the memory allocated to the
 133         argument, as it is replaced by the results by the unique caller.
 134         (build_relations): Merely invoke transpose: it handles the memory
 135         deallocation.
 136         Improve variable locality.
 137         Avoid variables used as mere abbreviations.
 138         (compute_lookaheads): Use arrays instead of pointers.
 139
 140 2001-12-05  Akim Demaille  <akim@epita.fr>
 141
 142         * src/lalr.c (initialize_F): Improve variable locality.
 143         Avoid variables used as mere abbreviations.
 144
 145 2001-12-05  Akim Demaille  <akim@epita.fr>
 146
 147         * src/derives.c (print_derives): Display the ruleno.
 148         * src/lalr.c (initialize_F, transpose): Better variable locality
 149         to improve readability.
 150         Avoid variables used as mere abbreviations.
 151
 152 2001-12-05  Akim Demaille  <akim@epita.fr>
 153
 154         * src/lalr.c (traverse): Use arrays instead of pointers.
 155
 156 2001-12-05  Akim Demaille  <akim@epita.fr>
 157
 158         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
 159         the handling of squeue.
 160         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
 161
 162
 163 2001-12-05  Akim Demaille  <akim@epita.fr>
 164
 165         Because useless nonterminals are now kept alive (instead of being
 166         `destroyed'), we now sometimes examine them, and store information
 167         related to them.  Hence we need to know their number, and adjust
 168         memory allocations.
 169
 170         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
 171         static.
 172         * src/LR0.c (allocate_itemsets): The memory allocated to
 173         `symbol_count' was used for two different purpose: once to count
 174         the number of occurrences of each symbol, and later reassigned to
 175         `shift_symbol', containing the symbol that can be shifted from a
 176         given state.
 177         Deobfuscate, i.e., allocate, use and free `symbol_count' here
 178         only, and...
 179         (new_itemsets): Allocate `shift_symbol' here.
 180         (allocate_itemsets): symbol_count includes useless nonterminals.
 181         Make room for them.
 182         (free_storage): Use `free', not `XFREE', for pointers that cannot
 183         be null.
 184
 185
 186 2001-12-05  Akim Demaille  <akim@epita.fr>
 187
 188         * src/nullable.c (set_nullable): Deobfuscate the handling of
 189         ritem.
 190         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
 191
 192
 193 2001-12-05  Akim Demaille  <akim@epita.fr>
 194
 195         * src/gram.c, src/gram.h (ritem_print): New.
 196         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
 197         (This useless function was defined only to work around VMS linkers
 198         that can't handle compilation units with variables only).
 199         * src/reduce.c (dump_grammar): Use it to trace the construction of
 200         ritem.
 201
 202 2001-12-04  Paul Eggert  <eggert@twinsun.com>
 203
 204         * src/bison.simple (union yyalloc): Change member names
 205         to be the same as the stack names.
 206         (yyparse): yyptr is now union yyalloc *, not char *.
 207         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
 208         and may generate better code on some machines.
 209         (yystpcpy): Use prototype if __STDC__ is defined, not just
 210         if __cplusplus is defined.
 211
 212 2001-11-30  Akim Demaille  <akim@epita.fr>
 213
 214         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
 215         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
 216         Gettext doesn't compile cleanly, and dies with -Werror.
 217         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
 218         Include WARNING_CFLAGS here.
 219         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
 220         before being defined.
 221
 222 2001-11-30  Paul Eggert  <eggert@twinsun.com>
 223
 224         * lib/quotearg.h (quotearg_n, quotearg_n_style):
 225         First arg is int, not unsigned.
 226         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
 227         (SIZE_MAX, UINT_MAX): New macros.
 228         (quotearg_n_options): Abort if N is negative.
 229         Avoid overflow check on hosts where size_t is 64 bits and int
 230         is 32 bits, as overflow is impossible there.
 231         Fix off-by-one typo that caused unnecessary reallocation.
 232
 233 2001-11-30  Paul Eggert  <eggert@twinsun.com>
 234
 235         Name space cleanup in generated parser.
 236
 237         * doc/bison.texinfo (Bison Parser): Discuss system headers
 238         and their effect on the user name space.
 239
 240         * src/bison.simple:
 241         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
 242         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
 243         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
 244
 245         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
 246         on user names when possible.
 247
 248         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
 249         Simplify test for whather <alloca.h> exists.
 250
 251         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
 252
 253         (<stdio.h>): Include if YYDEBUG.
 254
 255         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
 256         ! defined (yyoverflow) && ! defined (yymemcpy).
 257
 258         (yymemcpy, yyparse): Rename local variables as needed so that
 259         they all begin with 'yy'.
 260
 261         (yystrlen, yystpcpy): New functions.
 262
 263         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
 264         All uses changed.
 265
 266         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
 267         instead of relying on string.h functions.  Use YYSTACK_ALLOC
 268         and YYSTACK_FREE instead of malloc and free.
 269
 270 2001-11-30  Akim Demaille  <akim@epita.fr>
 271
 272         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
 273         if body instead of `;' to pacify GCC's warnings.
 274
 275 2001-11-30  Akim Demaille  <akim@epita.fr>
 276
 277         Instead of mapping the LHS of unused rules to -1, keep the LHS
 278         valid, but flag the rules as invalid.
 279
 280         * src/gram.h (rule_t): `useful' is a new member.
 281         * src/print.c (print_grammar): Adjust.
 282         * src/derives.c (set_derives): Likewise.
 283         * src/reader.c (packgram, reduce_output): Likewise.
 284         * src/reduce.c (reduce_grammar_tables): Likewise.
 285         * tests/reduce.at (Underivable Rules, Useless Rules): New.
 286
 287 2001-11-30  Akim Demaille  <akim@epita.fr>
 288
 289         * src/reduce.c (reduce_output): Formatting changes.
 290         * src/print.c (print_results, print_grammar): Likewise.
 291         * tests/regression.at (Rule Line Numbers)
 292         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
 293
 294 2001-11-30  Akim Demaille  <akim@epita.fr>
 295
 296         * src/reduce.c (nonterminals_reduce): Instead of throwing away
 297         useless nonterminals, move them at the end of the symbol arrays.
 298         (reduce_output): Adjust.
 299         * tests/reduce.at (Useless Nonterminals): Adjust.
 300
 301 2001-11-30  Akim Demaille  <akim@epita.fr>
 302
 303         * src/reduce.c: Various comment/formatting changes.
 304         (nonterminals_reduce): New, extracted from...
 305         (reduce_grammar_tables): here.
 306         (reduce_grammar): Call nonterminals_reduce.
 307
 308 2001-11-29  Paul Eggert  <eggert@twinsun.com>
 309
 310         * src/bison.simple (YYSTACK_REALLOC): Remove.
 311         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
 312         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
 313         New macros.
 314         (union yyalloc): New type.
 315         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
 316         an arbitrary restriction on hosts where size_t is wider than int.
 317
 318         (yyparse): Don't dump core if alloca or malloc fails; instead, report
 319         a parser stack overflow.  Allocate just one block of memory for all
 320         three stacks, instead of allocating three blocks; this typically is
 321         faster and reduces fragmentation.
 322
 323         Do not limit the number of items in the stack to a value that fits
 324         in 'int', as this is an arbitrary limit on hosts with 64-bit
 325         size_t and 32-bit int.
 326
 327 2001-11-28  Akim Demaille  <akim@epita.fr>
 328
 329         * src/LR0.c (shifts_new): New.
 330         (save_shifts, insert_start_shift, augment_automaton): Use it.
 331
 332 2001-11-28  Akim Demaille  <akim@epita.fr>
 333
 334         * src/closure.c (closure): `b' and `ruleno' denote the same value:
 335         keep ruleno only.
 336
 337 2001-11-28  Akim Demaille  <akim@epita.fr>
 338
 339         * src/closure.c (closure): Instead of looping over word in array
 340         then bits in words, loop over bits in array.
 341
 342 2001-11-28  Akim Demaille  <akim@epita.fr>
 343
 344         * src/closure.c (closure): No longer optimize the special case
 345         where all the bits of `ruleset[r]' are set to 0, to make the code
 346         clearer.
 347
 348 2001-11-28  Akim Demaille  <akim@epita.fr>
 349
 350         * src/closure.c (closure): `r' and `c' are new variables, used to
 351         de-obfuscate accesses to RULESET and CORE.
 352
 353 2001-11-28  Akim Demaille  <akim@epita.fr>
 354
 355         * src/reduce.c (reduce_print): Use ngettext.
 356         (dump_grammar): Improve the trace accuracy.
 357
 358 2001-11-28  Akim Demaille  <akim@epita.fr>
 359
 360         * src/reduce.c (dump_grammar): Don't translate trace messages.
 361
 362 2001-11-28  Akim Demaille  <akim@epita.fr>
 363
 364         * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
 365         * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
 366         as all tags are free'ed afterwards.
 367         From Enrico Scholz.
 368
 369 2001-11-27  Akim Demaille  <akim@epita.fr>
 370
 371         * src/system.h: Use intl/libgettext.h.
 372         * src/Makefile.am (INCLUDES): Add -I $(top_srcdir).
 373

 375
 376         * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
 377         use alloca when we didn't want to, and vice versa.
 378
 379 2001-11-27  Akim Demaille  <akim@epita.fr>
 380
 381         * tests/torture.at (Exploding the Stack Size with Malloc):
 382         s/YYSTACK_USE_ALLOCA_ALLOCA/YYSTACK_USE_ALLOCA/.
 383
 384 2001-11-27  Akim Demaille  <akim@epita.fr>
 385
 386         * src/files.c: Include error.h.

1698
1699         * src/reader.c (gensym): `gensym_count' is your own.
1700         Use a static buf to create the symbol name, as token_buffer is no

1704
1705         * src/conflicts.c (conflict_report): Be sure not to append to res

1712         New, from fileutils 4.0.37.
1713         * configure.in: Require Autoconf 2.49c.  I took some time before
1714         making this decision.  This is the only way out for portability
1715         issues in Bison, it would mean way too much duplicate effort to
1716         import in Bison features implemented in 2.49c since 2.13.
1717         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

1735
1736         * src/lex.h: Rename all the tokens:

1738         s/\bIDENTIFIER\b/tok_identifier/g;
1739         etc.
1740         Let them be enums, not #define, to ease debugging.
1741         Adjust all the code.
1742
1743 2001-01-18  Akim Demaille  <akim@epita.fr>
1744

1748 2001-01-18  Akim Demaille  <akim@epita.fr>
1749
1750         Since we now use obstacks, more % directives can be enabled.
1751
1752         * src/lex.c (percent_table): Also accept `%yacc',
1753         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
1754         `%debug'.
1755         Handle the actions for `%semantic_parser' and `%pure_parser' here,
1756         instead of returning a token.
1757         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
1758         * src/reader.c (read_declarations): Adjust.
1759         * src/files.c (open_files): Don't call `compute_base_names', don't
1760         compute `attrsfile' since they depend upon data which might be
1761         *in* the input file now.
1762         (output_files): Do it here.
1763         * src/output.c (output_headers): Document the fact that this patch

1789         FILE * parameters.
1790
1791 2000-12-20  Akim Demaille  <akim@epita.fr>
1792
1793         * src/files.c (open_files): Actually the `.output' file is based
1794         on the short_base_name, not base_name.

1796
1797 2000-12-20  Akim Demaille  <akim@epita.fr>
1798
1799         * src/bison.s1: Remove, we now use directly...

1823         (stringappend): Be just like strcat but allocate.
1824         (base_names): Eve out from open_files.
1825         Try to simplify the rather hairy computation of base_name and
1826         short_base_name.
1827         (open_files): Use it.
1828         * tests/suite.at (Checking output file names): New test.

1846 2000-12-19  Akim Demaille  <akim@epita.fr>
1847
1848         Let the handling of the skeleton files be local to the procedures

1900         * lib/obstack.h: Formatting changes.
1901         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
1902         prevents type checking.
1903         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
1904         cast the value to (void *): assigning a `foo *' to a `void *'
1905         variable is valid.
1906         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
1907         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

1944

1987         * src/main.c (main): Don't use `atexit' to register `done', since
1988         it no longer has to remove tmp files, just call `output_files'
1989         when there are no errors.
1990
1991 2000-11-02  Akim Demaille  <akim@epita.fr>

2091
2092 2000-10-04  Akim Demaille  <akim@epita.fr>
2093
2094         When a literal string is used to define two different tokens,
2095         `bison -v' segfaults.
2096         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
2097
2098         * tests/regression.m4: New file.

2109 2000-10-02  Paul Eggert  <eggert@twinsun.com>
2110
2111         * bison.s1 (yyparse): Assign the default value
2112         unconditionally, to avoid a GCC warning and make the parser a
2113         tad smaller.
2114
2115 2000-10-02  Akim Demaille  <akim@epita.fr>
2116
2117         * src/getargs.c (getargs): Don't dump `--help' on unrecognized

2121
2122         * src/derives.c, src/print.c, src/reduce.c: To ease the

2124
2125 2000-10-02  Akim Demaille  <akim@epita.fr>
2126
2127         The location tracking mechanism is precious for parse error
2128         messages.  Nevertheless, it is enabled only when `@n' is used in
2129         the grammar, which is a different issue (you can use it in error
2130         message, but not in the grammar per se).  Therefore, there should
2131         be another means to enable it.
2132
2133         * src/getargs.c (getargs): Support `--locations'.
2134         (usage): Report it.
2135         * src/getargs.h (locationsflag): Export it.
2136         * src/lex.c (percent_table): Support `%locations'.
2137         * src/reader.c (yylsp_needed): Remove this variable, now replaced
2138         with `locationsflag'.
2139         * doc/bison.texinfo: Document `--locations' and `%locations'.
2140         Sort the options.
2141         * tests/calc.m4: Test it.
2142
2143         For regularity of the names, replace each
2144         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
2145         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
2146         In addition replace each `flag' with `_flag'.
2147
2148 2000-10-02  Akim Demaille  <akim@epita.fr>
2149
2150         Also test parse error messages, including with YYERROR_VERBOSE.
2151
2152         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
2153         associative).
2154         Use it to check the computations.
2155         Use it to check `nonassoc' is honored.
2156         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
2157         `--yyerror-verbose'.
2158         (_AT_CHECK_CALC): Adjust to this option.
2159         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
2160
2161 2000-10-02  Akim Demaille  <akim@epita.fr>
2162
2163         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
2164         the latter demonstrates a flaw in the handling of non debugging
2165         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
2166         was used in order to simplify:
2167
2168         #if YYDEBUG
2169         if (yydebug)
2170         {
2171         ...
2172         }
2173         #endif
2174
2175         into
2176
2177         if (yydebug)
2178         {
2179         ...
2180         }
2181
2182         unfortunately this leads to a CPP conflict when
2183         `--name-prefix=foo' is used since it produces `#define yydebug
2184         foodebug'.
2185
2186         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
2187         (YYDPRINTF): New macro.
2188         Spread its use.
2189         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
2190         the bison options.
2191         Also test `--verbose', `--defines' and `--name-prefix'.
2192
2193 2000-10-02  Akim Demaille  <akim@epita.fr>
2194
2195         Improve the readability of the produced parsers.
2196
2197         * src/bison.s1: Formatting changes.
2198         Improve the comment related to the `$' mark.
2199         (yydefault): Don't fall through to `yyresume': `goto' there.
2200         * src/output.c (output_parser): When the `$' is met, skip the end
2201         of its line.
2202         New variable, `number_of_dollar_signs', to check there's exactly
2203         one `$' in the parser skeleton.
2204
2205 2000-10-02  Akim Demaille  <akim@epita.fr>
2206
2207         * lib/xstrdup.c: New file, from the fileutils.
2208         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
2209         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
2210         instead of strlen + xmalloc + strcpy.
2211         * src/symtab.c (copys): Remove, use xstrdup instead.
2212
2213 2000-10-02  Akim Demaille  <akim@epita.fr>
2214
2215         * src/gram.h (associativity): New enum type which replaces the
2216         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
2217         `right_assoc', `left_assoc' and `non_assoc'.
2218         Adjust all dependencies.
2219         * src/reader.c: Formatting changes.
2220         (LTYPESTR): Don't define it, use it as a literal in
2221         `reader_output_yylsp'.
2222         * src/symtab.h (symbol_class): New enum type which replaces the
2223         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

2234         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
2235         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
2236         difficult and introduced a lot of core dump.  It turns out that
2237         Bison used an implementation of `xmalloc' based on `calloc', and
2238         at various places it does depend upon the initialization to 0.  I
2239         have not tried to isolate the pertinent places, and all the former
2240         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
2241         someone should address this issue.
2242
2243         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
2244         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

2343
2344         `user_toknums' is output as a `short[]' in `output.c', while it is
2345         defined as a `int[]' in `reader.c'.  For consistency with the
2346         other output tables, `user_toknums' is now defined as a table of

2390         * src/system.h: Define PARAMS.
2391         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

2393         definitions in config.h.

2595
2596 2000-03-17  Akim Demaille  <akim@epita.fr>

2599         (copy_action): Use it.  Removed now unused `match', `ended',
2600         `cplus_comment'.

2609 2000-03-17  Akim Demaille  <akim@epita.fr>
2610
2611         Change the handling of @s so that they behave exactly like $s.
2612         There is now a pseudo variable @$ (readble and writable), location
2613         of the lhs of the rule (by default ranging from the location of
2614         the first symbol of the rhs, to the location of the last symbol,
2615         or, if the rhs is empty, YYLLOC).
2616
2617         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2618         yyval.
2619         (yyparse): When providing a default semantic action, provide a
2620         default location action.
2621         (after the $): No longer change `*YYLSP', just stack YYLOC the
2622         same way you stack YYVAL.
2623         * src/reader.c (read_declarations): Use warns.
2624         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2625         (copy_action, case '@'): Likewise.
2626         Use a standard error message, to save useless work from
2627         translators.
2628
2629 2000-03-17  Akim Demaille  <akim@epita.fr>
2630
2631         * src/bison.s1: Formatting and cosmetics changes.

2648
2649         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
2650         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2651         One `#if YYDEBUG' remains, since it uses variables which are
2652         defined only if `YYDEBUG != 0'.
2653
2654 2000-03-16  Akim Demaille  <akim@epita.fr>

2678         handled via src/Makefile.am.

2680         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
2681         autoheader.

2686         the proper line number and file name.
2687         (DEFS): Propagate the location of bison library files and of the
2688         locale files.
2689         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
2690         builddir.
2691         * acinclude.m4: Remove, replaced by the directory m4.
2692         * m4/Makefile.am (EXTRA_DIST): New variable.
2693         * m4/gettext.m4: New file, from the fileutils.

3361         (warnsss): New error reporting functions.  Avoid abort for error.
3362
3363         * src/lex.h:
3364         Added THONG and NOOP for alias processing.
3365         Added SETOPT for the new code that allows setting options with %flags.
3366
3367         * src/lex.c:
3368         Include getopt.h.  Add some extern decls.

3370         (literalchar); new function to deal with reading \ escapes.
3371         (lex): Use literalchar.
3372         (lex): Implemented "..." tokens.
3373         (literalchar, lex, parse_percent_token): Made tokenbuffer
3374         always contain the token.  This includes growing the token
3375         buffer while reading an integer.

3377         (parse_percent_token): Added % declarations as another
3378         way to specify the flags -n, -l, and -r.  Also added hooks for
3379         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
3380         major changes to files.c.
3381         (lex) Retain in the incoming stream a character following
3382         an incorrect '/'.
3383         (skip_white_space, lex):  Revised most error messages
