| 3 | Version 1.75b. |
| 4 | |
| 5 | * data/glr.c (yydoAction): Return YYRESULTTAG, not int. |
| 6 | (yyglrReduce): Return yyok, not 0. |
| 7 | This should avoid the enumerated-type warnings reported |
| 8 | by Nelson H.F. Beebe in |
| 9 | <http://mail.gnu.org/pipermail/bug-bison/2002-November/001872.html>. |
| 10 | |
| 11 | * lib/bbitset.h (BITSET_INLINE): Remove. |
| 12 | * lib/bitset.h [! BITSET_INLINE]: Remove. |
| 13 | (bitset_set, bitset_reset, bitset_test): Rename local vars |
| 14 | to avoid shadowing warnings by GCC. |
| 15 | |
| 16 | * data/glr.c (inline): Remove #define. It's the user's |
| 17 | responsibility to #define it away, just like 'const'. |
| 18 | This fixes one of the bugs reported by Nelson H.F. Beebe in |
| 19 | <http://mail.gnu.org/pipermail/bug-bison/2002-November/001873.html>. |
| 20 | |
| 21 | * Makefile.maint (po-check): Scan .l and .y files instead of the |
| 22 | .c and the .h files that they generate. This fixes the bug |
| 23 | reported by Tim Van Holder in: |
| 24 | <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html> |
| 25 | Look for N_ as well as for _. Try to avoid matching #define for |
| 26 | N_ and _. |
| 27 | * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c, |
| 28 | src/system.h. Add src/parse-gram.y, src/scan-gram.l. |
| 29 | * src/scan-gram.l: Revamp regular expressions so that " and ' |
| 30 | do not confuse xgettext. |
| 31 | |
| 32 | * src/struniq.h (struniq_new): Do not declare the return type |
| 33 | to be 'const'; this violates the C standard. |
| 34 | * src/struniq.c (struniq_new): Likewise. |
| 35 | |
| 36 | 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com> |
| 37 | |
| 38 | * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the |
| 39 | duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq |
| 40 | linker. |
| 41 | |
| 42 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 43 | |
| 44 | * Makefile.maint: Sync with Autoconf: |
| 45 | (local_updates): New. |
| 46 | |
| 47 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 48 | |
| 49 | * po/POTFILES.in (src/lalr.c, src/state.c): Remove |
| 50 | |
| 51 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 52 | |
| 53 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the |
| 54 | locations. |
| 55 | |
| 56 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 57 | |
| 58 | * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT, |
| 59 | not yyvalue. |
| 60 | |
| 61 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 62 | |
| 63 | * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New. |
| 64 | Use it to test the GLR parser. |
| 65 | |
| 66 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 67 | |
| 68 | * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton |
| 69 | defines it. |
| 70 | * data/glr.c (yystos): New. |
| 71 | (b4_yysymprint_generate, b4_yydestruct_generate): Invoke. |
| 72 | (YYDSYMPRINT): New. |
| 73 | (yyval): Don't define it, it is handled via M4. |
| 74 | (yyrecoverParseError): Free verbosely the discarded symbols. |
| 75 | * data/yacc.c (yysymprint): Remove, rather... |
| 76 | (b4_yysymprint_generate): invoke. |
| 77 | * data/c.m4 (b4_yysymprint_generate): New. |
| 78 | Accept pointers as arguments, as opposed to the version from |
| 79 | yacc.c. |
| 80 | (b4_yydestruct_generate): Likewise. |
| 81 | * tests/cations.at (Printers and Destructors): Use Bison directives |
| 82 | instead of CPP macros. |
| 83 | Don't rely on internal details. |
| 84 | |
| 85 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 86 | |
| 87 | * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New. |
| 88 | * data/yacc.c: Rename yychar1 as yytoken, as in glr.c. |
| 89 | Don't work on yychar (i.e., do set it to YYEMPTY, don't match |
| 90 | it against YYEMPTY and so forth), work on yytoken (i.e., set |
| 91 | it to YYEMPTY etc.). |
| 92 | (yydestruct): Replace with a b4_yydestruct_generate invocation. |
| 93 | (b4_symbol_actions): Remove. |
| 94 | * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands |
| 95 | for 0, end-of-input. |
| 96 | |
| 97 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 98 | |
| 99 | * doc/bison.texinfo (Destructor Decl): New. |
| 100 | |
| 101 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 102 | |
| 103 | * src/tables.c (tables_generate): Use free for pointers that |
| 104 | cannot be NULL, not XFREE. |
| 105 | (pack_vector): Use assert, not fatal, for bound violations. |
| 106 | * src/state.c (state_new): Likewise. |
| 107 | * src/reader.c (reader): Likewise. |
| 108 | * src/lalr.c (set_goto_map): Likewise. |
| 109 | * src/location.h (LOCATION_PRINT): If first_line is 0, just issue |
| 110 | the file name. |
| 111 | |
| 112 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 113 | |
| 114 | * src/scan-gram.l, src/reader.h (scanner_last_string_free): |
| 115 | Restore. |
| 116 | * src/scan-gram.l (last_string): Is global to the file, not to |
| 117 | yylex. |
| 118 | * src/parse-gram.y (input): Don't append the epilogue here, |
| 119 | (epilogue.opt): do it here, and free the scanner's obstack. |
| 120 | * src/reader.c (epilogue_set): Rename as... |
| 121 | (epilogue_augment): this. |
| 122 | * data/c.m4 (b4_epilogue): Defaults to empty. |
| 123 | |
| 124 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 125 | |
| 126 | * src/getargs.c (long_options): Remove duplicates. |

| 133 | |
| 134 | * src/struniq.h, src/struniq.c (struniq_t): Is const. |
| 135 | (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New. |
| 136 | |
| 137 | Use struniq for symbols. |
| 138 | |
| 139 | * src/symtab.h (symbol_t): The tag member is a struniq. |
| 140 | (symbol_type_set): Adjust. |
| 141 | * src/symtab.c (symbol_new): Takes a struniq. |
| 142 | (symbol_free): Don't free the tag member. |
| 143 | (hash_compare_symbol_t, hash_symbol_t): Rename as... |
| 144 | (hash_compare_symbol, hash_symbol): these. |
| 145 | Use the fact that tags as struniqs. |
| 146 | (symbol_get): Use struniq_new. |
| 147 | * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get): |

| 153 | (TYPE, current_type): Are struniq. |
| 154 | |
| 155 | Use struniq for file names. |
| 156 | |
| 157 | * src/files.h, src/files.c (infile): Split into... |
| 158 | (grammar_file, current_file): these. |

| 161 | * src/getargs.c (getargs): Likewise. |
| 162 | * src/complain.h, src/complain.c: Likewise. |
| 163 | * src/main.c (main): Call struniqs_new early enough to use it for |
| 164 | file names. |
| 165 | Don't free the input file name. |
| 166 | |
| 167 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 168 | |

| 179 | |
| 180 | 2002-11-11 Paul Eggert <eggert@twinsun.com> |
| 181 | |
| 182 | Revamp to fix many (but not all) of the C- and M4-related quoting |
| 183 | problems. Among other things, this fixes the Bison bug reported |
| 184 | by Jan Hubicka when processing the Bash grammar; see: |
| 185 | <http://mail.gnu.org/pipermail/bison-patches/2002-November/001329.html> |
| 186 | |
| 187 | Use new @ escapes consistently. Represent brackets with @{ and @} |
| 188 | rather than @<:@ and @:>@, since this works a bit better with dumb |
| 189 | editors like vi. Represent @ with @@, since @ is now consistently |
| 190 | an escape. Use @oline@ and @ofile@ rather than __oline__ and |
| 191 | __ofile__, to avoid unexpected expansions. Similarly, use @output |
| 192 | rather than #output. |
| 193 | |
| 194 | * data/c.m4 (b4_copyright): Omit file name from comment, since |
| 195 | the file name could contain "*/". |
| 196 | (b4_synclines_flag): Don't quote the 2nd argument; it should already |
| 197 | be quoted. All uses changed. |
| 198 | |
| 199 | * data/glr.c: Use new @ escapes consistently. |
| 200 | (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name, |
| 201 | b4_output_header_suffix, b4_output_header_name, b4_header_guard): |
| 202 | Remove, since they couldn't handle arbitrary characters in file |
| 203 | names. |
| 204 | * data/lalr1.cc: Likewise. |
| 205 | * data/yacc.c: Likewise. |
| 206 | |
| 207 | * src/files.c (output_infix): Remove; all uses removed. |
| 208 | * src/files.h: Likewise. |
| 209 | |
| 210 | * data/glr.c: Remove use of "#ifdef b4_header_guard", since it |
| 211 | mishandled funny characters in file names, and anyway it isn't |
| 212 | needed any more. |
| 213 | * data/yacc.c: Likewise. |
| 214 | * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard. |
| 215 | |
| 216 | * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would. |
| 217 | * data/yacc.c: Likewise. |
| 218 | |
| 219 | * src/muscle_tab.c: Include quotearg.h, since we need to quote C |
| 220 | strings now. |
| 221 | (muscle_init): Quote filename as a C string. |
| 222 | * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused. |
| 223 | (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros. |
| 224 | * src/output.c (escaped_file_name_output): New function. |
| 225 | (prepare_symbols): Quote tokens for M4. |
| 226 | (prepare): Don't insert output_infix, output_prefix, |
| 227 | output_parser_name, output_header_name; this is now down by scan-skel. |
| 228 | Insert skeleton as a C string. |
| 229 | |
| 230 | * src/output.c (user_actions_output, symbol_destructors_output, |
| 231 | symbol_printers_output): Quote filenames for C and M4. |
| 232 | * src/reader.c (prologue_augment, epilogue_set): Likewise. |
| 233 | |
| 234 | * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash |
| 235 | escapes other than \\ and \'; this simplifies the code. |
| 236 | (<SC_STRING>): Likewise, for \\ and \". |
| 237 | (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE, |
| 238 | SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too. |
| 239 | Use new escapes @{ and @} for [ and ]. |
| 240 | |
| 241 | * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing |
| 242 | them with auto vars. |
| 243 | Switch to new escape scheme, where @ is the escape character uniformly. |
| 244 | Abort if a stray escape character is found. Avoid unbounded input |
| 245 | buffer when parsing non-escaped text. |
| 246 | |
| 247 | * tests/input.at (Torturing the Scanner): Add tests that @oline@, |
| 248 | __oline__, #output, $@, and @{ do not have unintended meanings. |
| 249 | |
| 250 | 2002-11-09 Paul Eggert <eggert@twinsun.com> |
| 251 | |
| 252 | Fix the test failure due to GCC warnings described in |
| 253 | <http://mail.gnu.org/pipermail/bug-bison/2002-November/001815.html>. |
| 254 | * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which |
| 255 | evaluate to 0 if it's impossible for NINF to be in the respective |
| 256 | table. |
| 257 | (yygetLRActions, yyrecoverParseError): Use them. |
| 258 | |
| 259 | * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were |
| 260 | counted in the token inserted at end of file. Now takes |
| 261 | location_t *, not location_t, so that the location can be |
| 262 | adjusted. All uses changed. |
| 263 | |
| 264 | * tests/regression.at (Invalid inputs): Adjust wording in |
| 265 | diagnostic to match the new behavior. |
| 266 | |
| 267 | * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR, |
| 268 | AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR, |
| 269 | AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x)) |
| 270 | abort ();'. This reduces the runtime of the "Many lookaheads" |
| 271 | test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running |
| 272 | GCC 3.2. |
| 273 | |
| 274 | 2002-11-07 Paul Eggert <eggert@twinsun.com> |
| 275 | |
| 276 | * src/parse-gram.y (CHARACTER): Remove unused token. |
| 277 | All uses removed. |
| 278 | |
| 279 | * src/scan-gram.l: Remove stack option. We no longer use the |
| 280 | stack, since the stack was never deeper than 1; instead, use the |
| 281 | new auto var c_context to record the stacked value. |
| 282 | |
| 283 | Remove nounput option. At an unexpected end of file, we now unput |
| 284 | the minimal input necessary to end cleanly; this simplifies the |
| 285 | code. |
| 286 | |
| 287 | Avoid unbounded token sizes where this is easy. |
| 288 | |
| 289 | (unexpected_end_of_file): New function. |
| 290 | Use it to systematize the error message on unexpected EOF. |
| 291 | (last-string): Now auto, not static. |
| 292 | (YY_OBS_FREE): Remove unnecessary do while (0) wrapper. |
| 293 | (scanner_last_string_free): Remove; not used. |
| 294 | (percent_percent_count): Move decl to just before use. |
| 295 | (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file, |
| 296 | not the (never otherwised-used) CHARACTER. |
| 297 | |
| 298 | 2002-11-07 Akim Demaille <akim@epita.fr> |
| 299 | |
| 300 | Let yyerror always receive the msg as last argument, so that |
| 301 | yyerror can be variadic. |
| 302 | |
| 303 | * data/yacc.c (b4_yyerror_args): New. |
| 304 | Use it when calling yyerror. |
| 305 | * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New. |
| 306 | Use it when calling yyerror. |
| 307 | * doc/bison.texinfo (Error Reporting): Adjust. |
| 308 | * tests/calc.at (_AT_DATA_CALC_Y): Adjust. |
| 309 | * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust. |
| 310 | |
| 311 | 2002-11-06 Akim Demaille <akim@epita.fr> |
| 312 | |
| 313 | #line should have quoted strings. |
| 314 | Ideally, this should be done by m4_quotearg. |
| 315 | |
| 316 | * src/scan-skel.l: Include quotearg.h. |
| 317 | Quote __ofile__. |
| 318 | * src/output.c (symbol_printers_output) |
| 319 | (symbol_destructors_output): Quote the file name. |
| 320 | |
| 321 | 2002-11-06 Akim Demaille <akim@epita.fr> |
| 322 | |
| 323 | * tests/regression.at (Invalid inputs): Adjust to the recent |
| 324 | messages. |
| 325 | |
| 326 | 2002-11-06 Akim Demaille <akim@epita.fr> |
| 327 | |
| 328 | Restore --no-lines. |
| 329 | Reported by Jim Kent. |
| 330 | |
| 331 | * data/c.m4 (b4_syncline): New. |
| 332 | * data/glr.c, data/yacc.c, data/lalr1.cc: Use it. |
| 333 | * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline. |
| 334 | * src/output.c (user_actions_output): Likewise. |
| 335 | (prepare): Define 'b4_synclines_flag'. |
| 336 | * src/muscle_tab.c (muscle_init): Don't define b4_linef. |
| 337 | |
| 338 | 2002-11-06 Akim Demaille <akim@epita.fr> |
| 339 | |
| 340 | * src/main.c (main): Free `infile'. |
| 341 | * src/scan-gram.l (handle_syncline): New. |
| 342 | Recognize `#line'. |
| 343 | * src/output.c (user_actions_output, symbol_destructors_output) |
| 344 | (symbol_printers_output): Use the location's file name, not |
| 345 | infile. |
| 346 | * src/reader.c (prologue_augment, epilogue_set): Likewise. |
| 347 | |
| 348 | 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU> |
| 349 | |
| 350 | * src/tables.c (matching_state): Don't allow states to match if |
| 351 | either has GLR conflict entries. |
| 352 | |
| 353 | 2002-11-05 Paul Eggert <eggert@twinsun.com> |
| 354 | |
| 355 | * src/scan-gram.l: Use more accurate diagnostics, e.g. |
| 356 | "integer out of range" rather than "invalid value". |
| 357 | * tests/input.at (Invalid $n, Invalid @n): Change expected wording |
| 358 | accordingly. |
| 359 | |
| 360 | Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires. |
| 361 | Also, remove one static variable in the scanner. |
| 362 | |
| 363 | * src/scan-gram.l (braces_level): Now auto, not static. |
| 364 | Initialize to zero if the compiler is being picky. |
| 365 | (INITIAL): Clear braces_level instead of incrementing it. |
| 366 | (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code, |
| 367 | as POSIX 1003.1-2001 requires. |
| 368 | * src/system.h (IF_LINT): New macro, taken from coreutils. |
| 369 | * configure.ac: Define "lint" if --enable-gcc-warnings. |
| 370 | |
| 371 | 2002-11-05 Akim Demaille <akim@epita.fr> |
| 372 | |
| 373 | * src/scan-gram.l: When it starts with `%', complain about the |
| 374 | whole directive, not just that `invalid character: %'. |
| 375 | |
| 376 | 2002-11-04 Akim Demaille <akim@epita.fr> |
| 377 | |
| 378 | * Makefile.maint: Update from Autoconf. |

| 380 | |
| 381 | 2002-11-04 Akim Demaille <akim@epita.fr> |
| 382 | |
| 383 | * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex |
| 384 | and yyerror. |
| 385 | Have yyerror `use' its arguments. |

| 393 | clashes. |
| 394 | * src/scan-gram.l: Use [\'] instead of ['] to pacify |
| 395 | font-lock-mode. |
| 396 | Use complain_at. |
| 397 | Use quote, not quote_n since LOCATION_PRINT no longer uses the |
| 398 | slot 0. |
| 399 | |
| 400 | 2002-11-03 Paul Eggert <eggert@twinsun.com> |
| 401 | |
| 402 | * src/reader.c (get_merge_function, grammar_current_rule_check): |
| 403 | Use consistent diagnostics for reporting type name clashes. |
| 404 | Quote the types with <>, for consistency with Yacc. |
| 405 | * tests/input.at (Type Clashes): Adjust to diagnostic changes. |
| 406 | |
| 407 | 2002-11-03 Akim Demaille <akim@epita.fr> |
| 408 | |
| 409 | * data/c.m4 (b4_identification, b4_user_args, b4_parse_param): |
| 410 | New. |
| 411 | * data/yacc.m4 (b4_pure_args, b4_Pure_args): New. |
| 412 | (b4_parse_param): Remove. |
| 413 | Use b4_identification. |

| 415 | * data/glr.m4 (b4_parse_param): Remove. |
| 416 | (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args) |

| 418 | Use b4_identification. |
| 419 | (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by |

| 423 | the location, and the parse-params. |
| 424 | Adjust callers. |
| 425 | (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError): |
| 426 | When using a pure parser, also need the parse-params. |
| 427 | Adjust callers. |
| 428 | * tests/calc.at: Test pure (%pure-parser) and absolutely pure |
| 429 | (%pure-parser + %parse-param) LALR and GLR parsers. |
| 430 | (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF, |
| 431 | AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF, |
| 432 | AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF. |
| 433 | (_AT_DATA_CALC_Y): Equip for purity of yyerror. |
| 434 | (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF. |
| 435 | * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity. |

| 442 | 2002-11-03 Akim Demaille <akim@epita.fr> |
| 443 | |
| 444 | * tests/calc.at: Change all the AT_CHECK_CALC_LALR and |
| 445 | AT_CHECK_CALC_GLR invocations to use % directives, instead of |
| 446 | command line options. |
| 447 | * tests/cxx-type.at: Formatting changes. |
| 448 | |
| 449 | 2002-11-03 Paul Eggert <eggert@twinsun.com> |
| 450 | |
| 451 | * src/scan-gram.l: Revamp to fix POSIX incompatibilities, |
| 452 | to count columns correctly, and to check for invalid inputs. |
| 453 | |
| 454 | Use mbsnwidth to count columns correctly. Account for tabs, too. |
| 455 | Include mbswidth.h. |
| 456 | (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS. |
| 457 | (extend_location): New function. |
| 458 | (YY_LINES): Remove. |
| 459 | |
| 460 | Handle CRLF in C code rather than in Lex code. |
| 461 | (YY_INPUT): New macro. |
| 462 | (no_cr_read): New function. |
| 463 | |
| 464 | Scan UCNs, even though we don't fully handle them yet. |
| 465 | (convert_ucn_to_byte): New function. |
| 466 | |
| 467 | Handle backslash-newline correctly in C code. |
| 468 | (SC_LINE_COMMENT, SC_YACC_COMMENT): New states. |
| 469 | (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.; |
| 470 | all uses changed. |
| 471 | (tag, splice): New EREs. Do not allow NUL or newline in tags. |
| 472 | Use {splice} wherever C allows backslash-newline. |
| 473 | YY_STEP after space, newline, vertical-tab. |
| 474 | ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT). |
| 475 | |
| 476 | (letter, id): Don't assume ASCII; e.g., spell out a-z. |
| 477 | |
| 478 | ({int}, handle_action_dollar, handle_action_at): Check for integer |
| 479 | overflow. |
| 480 | |
| 481 | (YY_STEP): Omit trailing semicolon, so that it's more like C. |
| 482 | |
| 483 | (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00 |
| 484 | as well as \000. Check for UCHAR_MAX, not 255. |
| 485 | Allow \x with an arbitrary positive number of digits, as in C. |
| 486 | Check for overflow here. |
| 487 | Allow \? and UCNs, for compatibility with C. |
| 488 | |
| 489 | (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision |
| 490 | with quote slot used by complain_at. |
| 491 | |
| 492 | * tests/input.at: Add tests for backslash-newline, m4 quotes |
| 493 | in symbols, long literals, and funny escapes in strings. |
| 494 | |
| 495 | * configure.ac (jm_PREREQ_MBSWIDTH): Add. |
| 496 | * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c. |
| 497 | * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext. |
| 498 | * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4. |
| 499 | * m4/mbswidth.m4: New file, from GNU coreutils. |
| 500 | |
| 501 | * doc/bison.texinfo (Grammar Outline): Document // comments. |
| 502 | (Symbols): Document that trigraphs have no special meaning in Bison, |
| 503 | nor is backslash-newline allowed. |
| 504 | (Actions): Document that trigraphs have no special meaning. |
| 505 | |
| 506 | * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove; |
| 507 | no longer used. |
| 508 | |
| 509 | 2002-11-02 Paul Eggert <eggert@twinsun.com> |
| 510 | |
| 511 | * src/reader.c: Don't include quote.h; not needed. |
| 512 | (get_merge_function): Reword warning to be consistent with |
| 513 | type clash diagnostic in grammar_current_rule_check. |
| 514 | |
| 515 | * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two |
| 516 | bug in trigraph handling. |
| 517 | |
| 518 | * src/output.c (prepare_symbols): When printing token names, |
| 519 | escape "[" as "@<:@" and likewise for "]". |
| 520 | |
| 521 | * src/system.h (errno): Remove declaration, as we are now |
| 522 | assuming C89 or better, and C89 guarantees errno. |
| 523 | |
| 524 | 2002-10-30 Paul Eggert <eggert@twinsun.com> |
| 525 | |
| 526 | * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write): |
| 527 | Check for close failures. |
| 528 | * src/files.h (xfclose): Return void, not int, since it always |
| 529 | returned zero. |
| 530 | * src/files.c (xfclose): Likewise. Report I/O error if ferror |
| 531 | indicates one. |
| 532 | * src/output.c (output_skeleton): Use xfclose rather than fclose |
| 533 | and ferror. xfclose now checks ferror. |
| 534 | |
| 535 | * data/glr.c (YYLEFTMOST_STATE): Remove. |
| 536 | (yyreportTree): Use a stack-based leftmost state. This avoids |
| 537 | our continuing battles with bogus warnings about initializers. |
| 538 | |
| 539 | 2002-10-30 Akim Demaille <akim@epita.fr> |
| 540 | |
| 541 | * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only |
| 542 | #if. |
| 543 | |
| 544 | 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU> |
| 545 | |
| 546 | * tests/glr-regr1.at: New test for reported regressions. |
| 547 | * tests/testsuite.at: Add glr-regr1.at test. |
| 548 | * tests/Makefile.am: Add glr-regr1.at test. |
| 549 | |
| 550 | 2002-10-24 Paul Eggert <eggert@twinsun.com> |
| 551 | |
| 552 | Version 1.75a. |
| 553 | |
| 554 | * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration. |
| 555 | * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since |
| 556 | we use malloc. Don't assume 'A' through 'Z' are contiguous. |
| 557 | Don't assume strdup exists; POSIX says its an XSI extension. |
| 558 | Check for buffer overflow on input. |
| 559 | |
| 560 | 2002-10-24 Akim Demaille <akim@epita.fr> |
| 561 | |
| 562 | * src/output.c (output_skeleton): Don't disable M4sugar comments |
| 563 | too soon: it results in comments being expanded. |
| 564 | * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the |
| 565 | first output. |
| 566 | |
| 567 | 2002-10-24 Akim Demaille <akim@epita.fr> |
| 568 | |
| 569 | * data/yacc.c (m4_int_type): New. |
| 570 | * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed |
| 571 | char' as only yacc.c wants K&R portability. |
| 572 | * data/glr.c (yysigned_char): Remove. |
| 573 | * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name. |
| 574 | Reported by Quoc Peyrot. |
| 575 | |
| 576 | 2002-10-23 Paul Eggert <eggert@twinsun.com> |
| 577 | |
| 578 | * src/main.c (main): With --trace=time, report times even if a |
| 579 | non-fatal error occurs. Formerly, the times were reported in some |
| 580 | such cases but not in others. |
| 581 | * src/reader.c (reader): Just return if a complaint has been issued, |
| 582 | instead of exiting, so that 'main' can report times. |
| 583 | |
| 584 | 2002-10-22 Akim Demaille <akim@epita.fr> |
| 585 | |
| 586 | * src/system.h: Include sys/types. |
| 587 | Reported by Bert Deknuydt. |
| 588 | |
| 589 | 2002-10-23 Paul Eggert <eggert@twinsun.com> |
| 590 | |
| 591 | * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX. |
| 592 | Suggested by Art Haas. |
| 593 | |
| 594 | 2002-10-22 Paul Eggert <eggert@twinsun.com> |
| 595 | |
| 596 | * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit |
| 597 | decl; not needed any more. |
| 598 | * src/main.c (main): Use return to exit, undoing yesterday's change. |
| 599 | The last OS that we could find where this wouldn't work is |
| 600 | SunOS 3.5, and that's too old to worry about now. |
| 601 | |
| 602 | * data/glr.c (struct yyltype): Define members even when not |
| 603 | doing locations. This is more consistent with yacc.c, and it |
| 604 | works around the following bug reports: |
| 605 | http://mail.gnu.org/pipermail/bug-bison/2002-October/001764.html |
| 606 | http://mail.gnu.org/pipermail/bug-bison/2002-October/001769.html |
| 607 | and I hope it also fixes this bug report: |
| 608 | http://mail.gnu.org/pipermail/bug-bison/2002-October/001748.html |
| 609 | |
| 610 | * doc/bison.texinfo: Minor spelling and typographical fixes. Use |
| 611 | @acronym consistently. Standardize on "Yacc" instead of "YACC", |
| 612 | "Algol" instead of "ALGOL". Give a bit more history about BNF. |
| 613 | |
| 614 | 2002-10-22 Akim Demaille <akim@epita.fr> |
| 615 | |
| 616 | * data/README: New. |
| 617 | |
| 618 | 2002-10-21 Paul Eggert <eggert@twinsun.com> |
| 619 | |
| 620 | Be consistent about 'bool'; the old code used an enum in one |
| 621 | module and an int in another, and this violates the C standard. |
| 622 | * m4/stdbool.m4: New file, from coreutils 4.5.3. |
| 623 | * configure.ac (AC_HEADER_STDBOOL): Add. |
| 624 | * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4. |
| 625 | * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a) |
| 626 | * src/symtab.c (hash_compare_symbol_t): Likewise. |
| 627 | * src/system.h (bool, false, true): Use a definition consistent |
| 628 | with ../lib/hash.c. All uses changed. |
| 629 | |
| 630 | * src/complain.c (warning_issued): Renamed from warn_message_count, |
| 631 | so that we needn't worry about integer overflow (!). |
| 632 | Now of type bool. All uses changed. |
| 633 | (complaint_issued): Renamed from complain_message_count; likewise. |
| 634 | |
| 635 | * src/main.c (main): Use exit to exit with failure. |
| 636 | |
| 637 | * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS |
| 638 | rather than 1 and 0. |
| 639 | * src/main.c (main): Likewise. |
| 640 | * src/getargs.c (getargs): Likewise. |
| 641 | * src/reader.c (reader): Likewise. |
| 642 | |
| 643 | * src/getarg.c (getargs): Remove duplicate code for |
| 644 | "Try `bison --help'". |
| 645 | |
| 646 | * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2. |
| 647 | What was that "2" for? |
| 648 | |
| 649 | * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)). |
| 650 | * src/getargs.c (usage): Likewise. |
| 651 | |
| 652 | * src/getargs.c (getargs): When there are too few operands, report |
| 653 | the last one. When there are too many, report the first extra |
| 654 | one. This is how diffutils does it. |
| 655 | |
| 656 | 2002-10-20 Paul Eggert <eggert@twinsun.com> |
| 657 | |
| 658 | Remove K&R vestiges. |
| 659 | * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove. |
| 660 | * src/complain.c (VA_START): Remove. Assume prototypes. |
| 661 | (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro. |
| 662 | (private_strerror, warn_at, warn, complain_at, complain, fatal_at, |
| 663 | fatal): Assume prototypes. |
| 664 | * src/complain.h: Assume prototypes. |
| 665 | * src/system.h (PARAMS): Remove. |
| 666 | Include <limits.h> unconditionally, since it's guaranteeed even |
| 667 | for a freestanding C89 compiler. |
| 668 | (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them. |
| 669 | * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype. |
| 670 | |
| 671 | 2002-10-20 Akim Demaille <akim@epita.fr> |
| 672 | |
| 673 | * src/muscle_tab.c (muscle_grow): Remove trailing debugging code. |
| 674 | * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New. |
| 675 | (yyuserAction, yydoAction, yyglrReduce, yyresolveValue) |
| 676 | (yyresolveStates, yyresolveAction, yyresolveStack) |
| 677 | (yyprocessOneStack): Use them. |
| 678 | (yy_reduce_print): New. |
| 679 | * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param. |
| 680 | |

| 684 | arguments and output `void'. |
| 685 | (b4_c_function): Rename as... |
| 686 | (b4_c_function_def): this. |
| 687 | (b4_c_function_decl, b4_c_ansi_function_def) |
| 688 | (b4_c_ansi_function_decl): New. |
| 689 | Change the interpretation of the arguments: before `int, foo', now |
| 690 | `int foo, foo'. |
| 691 | * data/yacc.c (yyparse): Prototype and define thanks to these. |
| 692 | Adjust b4_c_function_def uses. |
| 693 | * data/glr.c (yyparse): Likewise, but ANSI only. |
| 694 | |
| 695 | 2002-10-20 Akim Demaille <akim@epita.fr> |
| 696 | |
| 697 | * src/output.c (prepare): Move the definition of `tokens_number', |
| 698 | `nterms_number', `undef_token_number', `user_token_number_max' |
| 699 | to... |

| 701 | (prepare_tokens): Rename as... |
| 702 | (prepare_symbols): this. |

| 707 | (prepare_states): here. |
| 708 | * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'. |
| 709 | |
| 710 | 2002-10-20 Akim Demaille <akim@epita.fr> |
| 711 | |
| 712 | * src/tables.h, src/tables.c, src/output.c: Comment changes. |
| 713 | |
| 714 | 2002-10-20 Akim Demaille <akim@epita.fr> |
| 715 | |
| 716 | * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to... |
| 717 | * data/c.m4: here. |
| 718 | |

| 727 | (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name): |
| 728 | These. |
| 729 | |
| 730 | 2002-10-19 Paul Eggert <eggert@twinsun.com> |
| 731 | |
| 732 | Do not create a temporary file, as that involves security and |
| 733 | cleanup headaches. Instead, use a pair of pipes. |
| 734 | Derived from a suggestion by Florian Krohm. |
| 735 | * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files. |
| 736 | * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove. |
| 737 | * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove. |
| 738 | (BISON_PREREQ_SUBPIPE): Add. |
| 739 | * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c. |
| 740 | Add subpipe.h, subpipe.c. |
| 741 | * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4. |
| 742 | * po/POTFILES.in: Add lib/subpipe.c. |
| 743 | * src/output.c: Include "subpipe.h". |
| 744 | (m4_invoke): Remove decl. |
| 745 | (scan_skel): New decl. |
| 746 | (output_skeleton): Use pipe rather than temporary file for m4 input. |
| 747 | Check that m4sugar.m4 is readable, to avoid deadlock. |
| 748 | Check for pipe I/O error. |
| 749 | * src/scan-skel.l (readpipe): Remove decl. |
| 750 | (scan_skel): New function, to be used in place of m4_invoke. |
| 751 | Read from stream rather than file. |
| 752 | |
| 753 | * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to |
| 754 | float, as this generates a warning on Solaris 8 + GCC 3.2 with |
| 755 | --enable-gcc-warnings. Instead, divide into 1.0 rather than 1; |
| 756 | this generates a more-accurate value anyway. |
| 757 | |
| 758 | * lib/timevar.c (timervar_accumulate): Rename locals to |
| 759 | avoid confusion with similarly-named more-global. |
| 760 | * src/muscle_tab.c (muscle_pair_list_grow): Likewise. |
| 761 | |
| 762 | * src/output.c (prepare): Use xstrdup to convert char const * |
| 763 | to char *, to avoid GCC warning. |
| 764 | |
| 765 | 2002-10-19 Akim Demaille <akim@epita.fr> |
| 766 | |
| 767 | * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS, |
| 768 | LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS. |
| 769 | Use them to have `calc.y' ready for %pure-parser. |
| 770 | * data/yacc.c (YYLEX): Pass a yylex return type to |
| 771 | b4_c_function_call. |
| 772 | |

| 775 | Prototype support of %lex-param and %parse-param. |
| 776 | |
| 777 | * src/parse-gram.y: Add the definition of the %lex-param and |
| 778 | %parse-param tokens, plus their rules. |
| 779 | Drop the `_' version of %glr-parser. |
| 780 | Add the "," token. |
| 781 | * src/scan-gram.l (INITIAL): Scan them. |
| 782 | * src/muscle_tab.c: Comment changes. |
| 783 | (muscle_insert, muscle_find): Rename `pair' as `probe'. |
| 784 | * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused. |
| 785 | (muscle_entry_s): The `value' member is no longer const. |
| 786 | Adjust all dependencies. |
| 787 | * src/muscle_tab.c (muscle_init): Adjust: use |
| 788 | MUSCLE_INSERT_STRING. |
| 789 | Initialize the obstack earlier. |
| 790 | * src/muscle_tab.h, src/muscle_tab.c (muscle_grow) |
| 791 | (muscle_pair_list_grow): New. |
| 792 | * data/c.m4 (b4_c_function_call, b4_c_args): New. |
| 793 | * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param. |
| 794 | * tests/calc.at: Use %locations, not --locations. |
| 795 | (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser. |
| 796 | |
| 797 | 2002-10-19 Akim Demaille <akim@epita.fr> |
| 798 | |
| 799 | * src/getargs.c (usage): Take status as argument and exit |
| 800 | accordingly. |
| 801 | Report the traditional `Try ... --help' message when status != 0. |
| 802 | (usage, version): Don't take a FILE * as arg, it is pointless. |
| 803 | (getargs): When there is an incorrect number of arguments, make it |
| 804 | an error, and report it GNUlically thanks to `usage ()'. |
| 805 | |
| 806 | 2002-10-18 Paul Eggert <eggert@twinsun.com> |
| 807 | |
| 808 | * data/glr.c (yyreportParseError): Don't assume that sprintf |
| 809 | yields the length of the printed string, as this is not true |
| 810 | on SunOS 4.1.4. Reported by Peter Klein. |
| 811 | |
| 812 | * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc. |
| 813 | * tests/conflicts.at (%nonassoc and eof): Likewise. |
| 814 | Fixes SunOS 4.1.4 test failure reported by Peter Klein. |
| 815 | |
| 816 | 2002-10-17 Akim Demaille <akim@epita.fr> |
| 817 | |
| 818 | * src/getargs.h (trace_e): Add trace_scan, and trace_parse. |
| 819 | * src/getargs.c (trace_types, trace_args): Adjust. |
| 820 | * src/reader.c (grammar_current_rule_prec_set) |
| 821 | (grammar_current_rule_dprec_set, grammar_current_rule_merge_set): |
| 822 | Standardize error messages. |
| 823 | And s/@prec/%prec/! |
| 824 | (reader): Use trace_flag to enable scanner/parser debugging, |
| 825 | instead of an adhoc scheme. |
| 826 | * src/scan-gram.l: Remove trailing debugging code. |
| 827 | |
| 828 | 2002-10-16 Paul Eggert <eggert@twinsun.com> |
| 829 | |
| 830 | * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as |
| 831 | MUSCLE_TAB_H. |
| 832 | |
| 833 | * NEWS: Officially drop support for building Bison with K&R C, |
| 834 | since it didn't work anyway and it's not worth worrying about. |
| 835 | * Makefile.maint (wget_files): Remove ansi2knr.c. |
| 836 | (ansi2knr.c-url_prefix): Remove. |
| 837 | * lib/.cvsignore: Remove ansi2knr, ansi2knr.*. |
| 838 | * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove. |
| 839 | * src/Makefile.am (AUTOMAKE_OPTIONS): Remove. |
| 840 | |
| 841 | 2002-10-15 Paul Eggert <eggert@twinsun.com> |
| 842 | |
| 843 | Stop using the "enum_" trick for K&R-style function definitions; |
| 844 | it confused me, and I was the author! Instead, assume that people |
| 845 | who want to use K&R C compilers (when using these modules in GCC, |
| 846 | perhaps?) will run ansi2knr. |
| 847 | |
| 848 | * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove. |
| 849 | All uses of "enum_" changed to "enum ". |
| 850 | * lib/ebitset.c (enum_ebitset_find_mode): Likewise. |
| 851 | * lib/lbitset.c (enum_lbitset_find_mode): Likewise. |

| 860 | abitset_size, abitset_small_list, abitset_subset_p, abitset_test, |
| 861 | abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero): |
| 862 | Use function prototypes; this removes the need for declaring |
| 863 | static functions simply to provide their prototypes. |
| 864 | * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_, |

| 919 | Version 1.75. |
| 920 | |
| 921 | 2002-10-14 Akim Demaille <akim@epita.fr> |
| 922 | |
| 923 | * tests/Makefile.am (maintainer-check-posix): New. |
| 924 | |
| 925 | 2002-10-14 Akim Demaille <akim@epita.fr> |
| 926 | |
| 927 | * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc |
| 928 | member. |
| 929 | |
| 930 | 2002-10-14 Akim Demaille <akim@epita.fr> |
| 931 | |
| 932 | * src/tables.c (table_ninf_remap): base -> tab. |
| 933 | Reported by Matt Rosing. |
| 934 | |
| 935 | 2002-10-14 Paul Eggert <eggert@twinsun.com> |
| 936 | |
| 937 | * tests/action.at, tests/calc.at, tests/conflicts.at, |
| 938 | tests/cxx-type.at, tests/headers.at, tests/input.at, |
| 939 | tests/regression.at, tests/synclines.at, tests/torture.at: |
| 940 | Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c", |
| 941 | so that the tests still work even if POSIXLY_CORRECT is set. |
| 942 | * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise. |
| 943 | |
| 944 | * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char, |
| 945 | for portability to K&R hosts. Fix typo: signed char is guaranteed |
| 946 | only to 127, not to 128. |
| 947 | * data/glr.c (yysigned_char): New type. |
| 948 | * data/yacc.c (yysigned_char): Likewise. |
| 949 | * tests/regression.at (Web2c Actions): signed char -> yysigned_char. |
| 950 | |
| 951 | 2002-10-13 Paul Eggert <eggert@twinsun.com> |
| 952 | |
| 953 | * data/yacc.c (yyparse): Rewrite to avoid "comparison is always |
| 954 | true due to limited range of data type" warning from GCC. |
| 955 | |
| 956 | * data/c.m4 (b4_token_defines): Protect against double-inclusion |
| 957 | by wrapping enum yytokentype's definition inside #ifndef |
| 958 | YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12. |
| 959 | |
| 960 | 2002-10-13 Akim Demaille <akim@epita.fr> |
| 961 | |
| 962 | * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction): |
| 963 | Un yy- yyrhs to avoid the name clash with the global YYRHS. |
| 964 | |
| 965 | 2002-10-13 Akim Demaille <akim@epita.fr> |
| 966 | |
| 967 | * Makefile.maint: Update from Autoconf 2.54. |
| 968 | * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54. |
| 969 | |
| 970 | 2002-10-13 Akim Demaille <akim@epita.fr> |
| 971 | |
| 972 | * src/print.c (print_state): Separate the list of solved conflicts |
| 973 | from the other items. |
| 974 | * tests/conflicts.at (Resolved SR Conflicts): Adjust. |
| 975 | |

| 978 | Let nondeterministic skeletons be usable with deterministic |
| 979 | tables. |
| 980 | |
| 981 | With the patch, GAWK compiled by GCC without -O2 passes its test |
| 982 | suite using a GLR parser driven by LALR tables. It fails with -O2 |
| 983 | because `struct stat' gives two different answers on my machine: |
| 984 | 88 (definition of an auto var) and later 96 (memset on this var). |
| 985 | Hence the stack is badly corrumpted. The headers inclusion is to |
| 986 | blame: if I move the awk.h inclusion before GLR's system header |
| 987 | inclusion, the two struct stat have the same size. |
| 988 | |
| 989 | * src/tables.c (pack_table): Always create conflict_table. |
| 990 | (token_actions): Always create conflict_list. |
| 991 | * data/glr.c (YYFLAG): Remove, unused. |
| 992 | |
| 993 | 2002-10-13 Akim Demaille <akim@epita.fr> |
| 994 | |
| 995 | * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code. |
| 996 | (O0FLAGS): New. |
| 997 | (VALGRIND, GXX): New. |
| 998 | * tests/atlocal.in (CFLAGS): Use O0FLAGS. |
| 999 | * tests/bison.in: Run $PREBISON a pre-command. |
| 1000 | * tests/Makefile.am (maintainer-check, maintainer-check-valgrind) |
| 1001 | (maintainer-check-g++): New. |
| 1002 | * Makefile.am (maintainer-check): New. |
| 1003 | |
| 1004 | 2002-10-13 Akim Demaille <akim@epita.fr> |
| 1005 | |
| 1006 | * data/glr.c: Formatting changes. |
| 1007 | Tweak some trace messages to match yacc.c's. |
| 1008 | |
| 1009 | 2002-10-13 Akim Demaille <akim@epita.fr> |
| 1010 | |
| 1011 | GLR parsers sometimes raise parse errors instead of performing the |
| 1012 | default reduction. |
| 1013 | Reported by Charles-Henry de Boysson. |
| 1014 | |
| 1015 | * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't |
| 1016 | check the length of the traces when %glr. |
| 1017 | (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from |
| 1018 | GLR's traces. |
| 1019 | (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New. |
| 1020 | Test GLR parsers. |
| 1021 | * data/glr.c (YYLEFTMOST_STATE): Fix its value. |
| 1022 | (yyltype): Remove the yy prefix from the member names. |
| 1023 | (yytable): Complete its comment. |
| 1024 | (yygetLRActions): Map error action number from YYTABLE from |
| 1025 | YYTABLE_NINF to 0. |
| 1026 | (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF |
| 1027 | (which was a bug: it should have been YYTABEL_NINF, and yet it was |
| 1028 | not satisfying as we could compare an YYACTION computed from |
| 1029 | YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the |
| 1030 | only value for error actions. |
| 1031 | (yyreportParseError): In verbose parse error messages, don't issue |
| 1032 | `error' in the list of expected tokens. |
| 1033 | * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the |
| 1034 | next action to perform to match glr.c's decoding. |
| 1035 | (yytable): Complete its comment. |
| 1036 | |
| 1037 | 2002-10-13 Paul Eggert <eggert@twinsun.com> |

| 1039 | Fix problem reported by Henrik Grubbstroem in |
| 1040 | <http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>: |
| 1041 | "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected, |
| 1042 | because the Bison parser reads the second action before reducing |
| 1043 | the first one. |
| 1044 | * src/scan-gram.l (rule_length): New static var. |
| 1045 | Use it to keep track of the rule length in the scanner, since |
| 1046 | we can't expect the parser to be in lock-step sync with the scanner. |
| 1047 | (handle_action_dollar, handle_action_at): Use this var. |
| 1048 | * tests/actions.at (Exotic Dollars): Test for the problem. |
| 1049 | |
| 1050 | 2002-10-12 Paul Eggert <eggert@twinsun.com> |
| 1051 | |
| 1052 | * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>. |
| 1053 | * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>. |
| 1054 | Include <sys/time.h> when checking for clock_t and struct tms. |
| 1055 | Use same include order as source. |
| 1056 | This is for the SunOS 4.1.4 porting bug reported by Peter Klein in |
| 1057 | <http://mail.gnu.org/pipermail/bug-bison/2002-October/001674.html>. |
| 1058 | |
| 1059 | * lib/timevar.c: Update copyright date and clarify comments. |
| 1060 | (get_time) [IN_GCC]: Keep the GCC version for reference. |
| 1061 | |
| 1062 | * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import |
| 1063 | GCC version as of today, then merge Bison's changes. |
| 1064 | Change "GCC" to "Bison" in copyright notice. timevar.def's |
| 1065 | author is Akim, so change that too. |
| 1066 | |
| 1067 | * src/reader.c (grammar_current_rule_check): |
| 1068 | Don't worry about the default action if $$ is untyped. |
| 1069 | Prevents bogus warnings reported by Jim Gifford in |
| 1070 | <http://mail.gnu.org/pipermail/bug-bison/2002-October/001673.html>. |
| 1071 | |
| 1072 | * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE. |
| 1073 | * data/glr.c, data/lalr1.cc, data/yacc.c: |
| 1074 | Output token definitions before the first part of user declarations. |
| 1075 | Fixes compatibility problem reported by Jim Gifford for kbd in |
| 1076 | <http://mail.gnu.org/pipermail/bug-bison/2002-October/001672.html>. |
| 1077 | |
| 1078 | 2002-10-11 Paul Eggert <eggert@twinsun.com> |
| 1079 | |
| 1080 | * data/yacc.c (yyreport_parse_error): Remove, putting its body into... |
| 1081 | (yyparse): here. This undoes some of the 2002-07-25 change. |
| 1082 | Compatibility problem reported by Ralf S. Engelschall with |
| 1083 | OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>. |
| 1084 | |
| 1085 | 2002-10-11 Akim Demaille <akim@epita.fr> |
| 1086 | |
| 1087 | * tests/regression.at Characters Escapes): New. |
| 1088 | * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and |
| 1089 | characters. |
| 1090 | Reported by Jan Nieuwenhuizen. |

| 1098 | Portability fixes for bitsets; this also avoids several GCC |
| 1099 | warnings. |
| 1100 | |
| 1101 | * lib/abitset.c: Include <stddef.h>, for offsetof. |
| 1102 | * lib/lbitset.c: Likewise. |
| 1103 | |
| 1104 | * lib/abitset.c (abitset_bytes): Return a size that is aligned |
| 1105 | properly for vectors of objects. Do not assume that adding a |
| 1106 | header size to a multiple of a word size yields a value that is |
| 1107 | properly aligned for the whole union. |
| 1108 | * lib/bitsetv.c (bitsetv_alloc): Likewise. |
| 1109 | |
| 1110 | * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new, |
| 1111 | unique names for structures. |

| 1143 | * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types. |
| 1144 | All instances of parameters of type enum bitset_opts are now of |
| 1145 | type enum_bitset_opts, to conform to the C Standard, and similarly |

| 1150 | Do not use "struct bitset_struct" to mean different things in |

| 1152 | the C Standard, which requires that structure types in different |
| 1153 | modules must be compatible if one is to be passed to the other. |
| 1154 | * lib/bbitset.h (bitset): Now points to a union, not to a struct. |
| 1155 | All instances of "struct bitset_struct *" replaced with "bitset". |

| 1197 | 2002-10-06 Paul Eggert <eggert@twinsun.com> |
| 1198 | |
| 1199 | * lib/bitset.h (bitset_reset): Do not assume that bitset_word is |
| 1200 | the same width as int. This reapplies a hunk of the 2002-08-12 patch |
| 1201 | <http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>, |
| 1202 | which was inadvertently undone by the 2002-09-30 patch. |

| 1211 | |
| 1212 | * doc/bison.texinfo: Minor spelling, grammar, and white space |
| 1213 | fixes. |
| 1214 | (Symbols): Mention that any negative value returned from yylex |
| 1215 | signifies end-of-input. Warn about negative chars. Mention |
| 1216 | the portable Standard C character set. |
| 1217 | |
| 1218 | The GNU coding standard says CFLAGS and YFLAGS are reserved |
| 1219 | for the installer to set. |

| 1508 | |
| 1509 | * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not |
| 1510 | size_t; the old version tried to do this but casted improperly. |
| 1511 | (bitset_bindex, bitset_windex): Now size_t, not unsigned long. |
| 1512 | (bitset_test): Now returns int, not unsigned long. |

| 1515 | (_): New macro. |
| 1516 | (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't |
| 1517 | name locals "index", as it generates unnecessary warnings on some |
| 1518 | hosts that have an "index" function. |
| 1519 | |

| 1542 | src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c, |
| 1543 | lib/timevar.c. |
| 1544 | Use src/parse-gram.y instead of src/parse-gram.c, as the gettext |
| 1545 | manual recommends. |
| 1546 | Similarly, use src/scan-gram.l instead of src/scan-gram.c. |
| 1547 | |
| 1548 | * src/complain.c (strerror_r): Remove decl; not needed. |
| 1549 | (strerror): Use same pattern as ../lib/error.c. |

| 1553 | * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int. |
| 1554 | |
| 1555 | * src/main.c (main): Cast result of bindtextdomain and textdomain |
| 1556 | to void, to avoid a GCC warning when --disable-nls is in effect. |
| 1557 | |
| 1558 | * src/scan-gram.l: Use strings rather than escapes when possible, |
| 1559 | to minimize the number of warnings from xgettext. |
| 1560 | (handle_action_dollar, handle_action_at): Don't use isdigit, |
| 1561 | as it mishandles negative chars and it may not work as expected |
| 1562 | outside the C locale. |
| 1563 | |
| 1564 | * src/symtab.c (symbol_get): Don't cast LHS of an assignment; |
| 1565 | this is a GCC extension and is not portable to other compilers. |
| 1566 | |

| 1568 | Do not include <ctype.h>; no longer needed. |
| 1569 | Do not include <malloc.h>; no longer needed (and generates |
| 1570 | warnings on OpenBSD 3.0). |
| 1571 | |
| 1572 | * tests/cxx-type.at (yylex): Do not pass signed char to isupper; |
| 1573 | it's not portable. |
| 1574 | |
| 1575 | * tests/regression.at: Do not use 'cc -c input.c -o input'; |
| 1576 | Sun C rejects this. Instead, use 'cc -c input.c -o input.o'. |
| 1577 | |
| 1578 | * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero |
| 1579 | exit status as failure, not just exit status 1. Sun C exits |
| 1580 | with status 2 sometimes. |
| 1581 | |

| 1583 | Use it for the two large tests. |

| 1603 | |
| 1604 | 2002-08-01 Akim Demaille <akim@epita.fr> |
| 1605 | |
| 1606 | Instead of attaching lookaheads and duplicating the rules being |
| 1607 | reduced by a state, attach the lookaheads to the reductions. |
| 1608 | |
| 1609 | * src/state.h (state_t): Remove the `lookaheads', |
| 1610 | `lookaheads_rule' member. |
| 1611 | (reductions_t): Add a `lookaheads' member. |
| 1612 | Use a regular array for the `rules'. |

| 1614 | to 0. |

| 1623 | (initialize_LA): this. |
| 1624 | (lalr_free): Adjust. |
| 1625 | * src/main.c (main): Don't free nullable and derives too early: it |
| 1626 | is used by --verbose. |
| 1627 | * src/print.c, src/print_graph.c, src/tables.c: Adjust. |
| 1628 | |
| 1629 | 2002-08-01 Akim Demaille <akim@epita.fr> |
| 1630 | |
| 1631 | * src/derives.h, src/derives.c (derives): A `rule_t***' instead of |
| 1632 | `rule_number_t**'. |

| 1645 | |
| 1646 | * lib/timevar.c (get_time): Include children time. |

| 1648 | state_t. |
| 1649 | * src/lalr.c (LA, LArule): Static. |
| 1650 | * src/lalr.h, src/lalr.c (lalr_free): New. |
| 1651 | * src/main.c (main): Call it. |
| 1652 | * src/tables.c (pack_vector): Check whether loc is >= to the |
| 1653 | table_size, not >. |
| 1654 | (pack_tables): Don't free froms, tos, conflict_tos, and pos... |
| 1655 | (tables_generate): do it, since that's also it which allocates |
| 1656 | them. |
| 1657 | Don't free LA and LArule, main does. |
| 1658 | |
| 1659 | 2002-07-31 Akim Demaille <akim@epita.fr> |
| 1660 | |

| 1686 | |
| 1687 | Steal GCC's --time-report support. |
| 1688 | |
| 1689 | * lib/timevar.c, lib/timevar.h, lib/timevar.def: New, |
| 1690 | stolen/adjusted from GCC. |
| 1691 | * m4/stage.m4: Remove time related checks. |
| 1692 | * m4/timevar.m4: New. |

| 1701 | 2002-07-31 Akim Demaille <akim@epita.fr> |
| 1702 | |
| 1703 | Let --trace have arguments. |
| 1704 | |
| 1705 | * src/getargs.h (enum trace_e): New. |
| 1706 | * src/getargs.c (trace_args, trace_types, trace_argmatch): New. |
| 1707 | (long_options, short_options): --trace/-T takes an optional |
| 1708 | argument. |
| 1709 | Change all the uses of trace_flag to reflect the new flags. |
| 1710 | * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets. |
| 1711 | |
| 1712 | Strengthen `stage' portability. |
| 1713 | |
| 1714 | * m4/stage.m4 (BISON_PREREQ_STAGE): New. |
| 1715 | * configure.in: Use it. |

| 1717 | * src/system.h: Include them when appropriate. |
| 1718 | * src/main.c (stage): Compile only when mallinfo, struct mallinfo, |
| 1719 | times and struct tms are available. |
| 1720 | |
| 1721 | 2002-07-30 Akim Demaille <akim@epita.fr> |
| 1722 | |

| 1724 | expected token. |
| 1725 | * tests/actions.at (Printers and Destructors): Adjust. |

| 1741 | 2002-07-30 Akim Demaille <akim@epita.fr> |
| 1742 | |
| 1743 | Report rules which are never reduced by the parser: those hidden |
| 1744 | by conflicts. |
| 1745 | |
| 1746 | * src/LR0.c (save_reductions): Don't make the final state too |
| 1747 | different: save its reduction (accept) instead of having a state |
| 1748 | without any action (no shift or goto, no reduce). |
| 1749 | Note: the final state is now a ``regular'' state, i.e., the |
| 1750 | parsers now contain `reduce 0' as default reduction. |
| 1751 | Nevertheless, since they decide to `accept' when yystate = |
| 1752 | final_state, they still will not reduce rule 0. |
| 1753 | * src/print.c (print_actions, print_reduction): Adjust. |
| 1754 | * src/output.c (action_row): Track reduced rules. |
| 1755 | (token_actions): Report rules never reduced. |

| 1758 | 2002-07-30 Akim Demaille <akim@epita.fr> |
| 1759 | |
| 1760 | `stage' was accidently included in a previous patch. |
| 1761 | Initiate its autoconfiscation. |
| 1762 | |
| 1763 | * configure.in: Look for malloc.h and sys/times.h. |
| 1764 | * src/main.c (stage): Adjust. |
| 1765 | Report only when trace_flag. |
| 1766 | |
| 1767 | 2002-07-29 Akim Demaille <akim@epita.fr> |
| 1768 | |
| 1769 | * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not |
| 1770 | state_number_t. |
| 1771 | (errs_t): symbol_t*, not symbol_number_t. |
| 1772 | (reductions_t): rule_t*, not rule_number_t. |
| 1773 | (FOR_EACH_SHIFT): New. |
| 1774 | * src/LR0.c, src/conflicts.c, src/lalr.c, src/output.c |
| 1775 | * src/print.c, src/print_graph.c: Adjust. |
| 1776 | |
| 1777 | 2002-07-29 Akim Demaille <akim@epita.fr> |
| 1778 | |
| 1779 | Use $accept and $end, as BYacc and BTYacc do, instead of $axiom and $. |
| 1780 | |
| 1781 | * src/symtab.h, src/symtab.c (eoftoken, axiom): Rename as... |
| 1782 | (endtoken, accept): these. |
| 1783 | * src/reader.c (reader): Set endtoken's default tag to "$end". |
| 1784 | Set undeftoken's tag to "$undefined" instead of "$undefined.". |
| 1785 | * doc/bison.texinfo (Table of Symbols): Mention $accept and $end. |
| 1786 | Adjust. |
| 1787 | |
| 1788 | 2002-07-29 Akim Demaille <akim@epita.fr> |
| 1789 | |
| 1790 | * src/reduce.c (reduce_grammar): When the language is empty, |
| 1791 | complain about the start symbol, not the axiom. |
| 1792 | Use its location. |
| 1793 | * tests/reduce.at (Empty Language): New. |
| 1794 | |
| 1795 | 2002-07-26 Akim Demaille <akim@epita.fr> |
| 1796 | |
| 1797 | * src/reader.h, src/reader.c (gram_error): ... can't get |
| 1798 | yycontrol without making too strong assumptions on the parser |
| 1799 | itself. |
| 1800 | * src/output.c (prepare_tokens): Use the real 0th value of |
| 1801 | token_translations instead of `0'. |
| 1802 | * src/parse-gram.y (yyerror): Don't rely on yycontrol being |
| 1803 | visible here. |
| 1804 | * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc |
| 1805 | for the time being: %locations ought to provide it to yyerror. |
| 1806 | |
| 1807 | 2002-07-25 Akim Demaille <akim@epita.fr> |
| 1808 | |
| 1809 | * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1. |
| 1810 | * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./. |
| 1811 | * tests/regression.at (Web2c Actions): Adjust. |
| 1812 | |
| 1813 | 2002-07-25 Akim Demaille <akim@epita.fr> |
| 1814 | |
| 1815 | Stop storing rules from 1 to nrules + 1. |
| 1816 | |
| 1817 | * src/LR0.c, src/closure.c, src/derives.c, src/gram.c, src/lalr.c |
| 1818 | * src/nullable.c, src/output.c, src/print.c, src/reader.c |
| 1819 | * src/reduce.c: Allocate and free from &rules[0], not &rules[1]. |
| 1820 | Iterate from 0 to nrules. |
| 1821 | Use rule_number_as_item_number and item_number_as_rule_number. |
| 1822 | Adjust to `derive' now containing possibly 0. |
| 1823 | * src/gram.h (rule_number_as_item_number, item_number_as_rule_number): |
| 1824 | Handle the `- 1' part in rule numbers from/to item numbers. |

| 3347 | (copy_at, copy_dollar): Instead of outputting the hard coded |
| 3348 | values of $$, $n and so forth, output invocation to b4_lhs_value, |
| 3349 | b4_lhs_location, b4_rhs_value, and b4_rhs_location. |
| 3350 | Note: this patch partially drops `semantic-parser' support: it |
| 3351 | always does `rule_length - n', where semantic parsers ought to |
| 3352 | always use `-n'. |
| 3353 | * data/bison.simple, data/bison.c++ (b4_lhs_value) |
| 3354 | (b4_lhs_location, b4_rhs_value, and b4_rhs_location: New. |

| 3399 | |
| 3400 | 2002-04-24 Robert Anisko <robert@lrde.epita.fr> |
| 3401 | |

| 3412 | * src/reader.c (copy_definition): Add a parameter to specify the |
| 3413 | obstack to fill, instead of using attrs_obstack unconditionally. |
| 3414 | (read_declarations): Pass pre_prologue_obstack to copy_definition if |
| 3415 | `%union' has not yet been seen, pass post_prologue_obstack otherwise. |

| 3439 | |
| 3440 | * src/reduce.c (dump_grammar): Move to... |
| 3441 | * src/gram.h, src/gram.c (grammar_dump): here. |

| 3460 | value for the error token, i.e., it will be assigned another |
| 3461 | number if the user assigned 256 to one of her tokens. |
| 3462 | (reader): Don't force 256 to error. |
| 3463 | * doc/bison.texinfo (Symbols): Adjust. |
| 3464 | * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR) |
| 3465 | (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3 |
| 3466 | etc. instead of 10, 20, 30 (which was used to `jump' over error |
| 3467 | (256) and undefined (2)). |
| 3468 | |
| 3469 | 2002-04-22 Akim Demaille <akim@epita.fr> |
| 3470 | |
| 3471 | Propagate more token_number_t. |

| 3501 | * src/system.h: Rely on HAVE_LIMITS_H. |
| 3502 | Suggested by Paul Eggert. |
| 3503 | |
| 3504 | 2002-04-09 Akim Demaille <akim@epita.fr> |
| 3505 | |
| 3506 | * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the |
| 3507 | full stderr, and strip it according to the bison options, instead |
| 3508 | of composing the error message from different bits. |
| 3509 | This makes it easier to check for several error messages. |
| 3510 | Adjust all the invocations. |
| 3511 | Add an invocation exercising the error token. |
| 3512 | Add an invocation demonstrating a stupid error message. |
| 3513 | (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0. |

| 3520 | errtoken->number. |
| 3521 | * src/reader.c (reader): Don't specify the user token number (2) |
| 3522 | for $undefined, as it uselessly prevents using it. |
| 3523 | * src/gram.h (token_number_t): Move to... |
| 3524 | * src/symtab.h: here. |
| 3525 | (state_t.number): Is a token_number_t. |
| 3526 | * src/print.c, src/reader.c: Use undeftoken->number instead of |
| 3527 | hard coded 2. |
| 3528 | (Even though this 2 is not the same as above: the number of the |
| 3529 | undeftoken remains being 2, it is its user token number which |
| 3530 | might not be 2). |
| 3531 | * src/output.c (prepare_tokens): Rename the `maxtok' muscle with |
| 3532 | `user_token_number_max'. |
| 3533 | Output `undef_token_number'. |
| 3534 | * data/bison.simple, data/bison.c++: Use them. |
| 3535 | Be sure to map invalid yylex return values to |
| 3536 | `undef_token_number'. This saves us from gratuitous SEGV. |
| 3537 | |
| 3538 | * tests/conflicts.at (Solved SR Conflicts) |
| 3539 | (Unresolved SR Conflicts): Adjust. |
| 3540 | * tests/regression.at (Web2c Actions): Adjust. |

| 3543 | |
| 3544 | * data/bison.c++: s/b4_item_number_max/b4_rhs_number_max/. |
| 3545 | Adding #line. |
| 3546 | Remove the duplicate `typedefs'. |
| 3547 | (RhsNumberType): Fix the declaration and various other typos. |
| 3548 | Use __ofile__. |
| 3549 | * data/bison.simple: Use __ofile__. |
| 3550 | * src/scan-skel.l: Handle __ofile__. |
| 3551 | |
| 3552 | 2002-04-08 Akim Demaille <akim@epita.fr> |
| 3553 | |
| 3554 | * src/gram.h (item_number_t): New, the type of item numbers in |
| 3555 | RITEM. Note that it must be able to code symbol numbers as |
| 3556 | positive number, and the negation of rule numbers as negative |
| 3557 | numbers. |
| 3558 | Adjust all dependencies (pretty many). |
| 3559 | * src/reduce.c (rule): Remove this `short *' pointer: use |
| 3560 | item_number_t. |
| 3561 | * src/system.h (MINSHORT, MAXSHORT): Remove. |
| 3562 | Include `limits.h'. |
| 3563 | Adjust dependencies to using SHRT_MAX and SHRT_MIN. |
| 3564 | (shortcpy): Remove. |
| 3565 | (MAXTABLE): Move to... |
| 3566 | * src/output.c (MAXTABLE): here. |

| 3568 | * data/bison.simple, data/bison.c++: Adjust. |
| 3569 | * tests/torture.at (Big triangle): Move the limit from 254 to |
| 3570 | 500. |
| 3571 | * tests/regression.at (Web2c Actions): Ajust. |
| 3572 | |
| 3573 | Trying with bigger grammars shows various phenomena: at 3000 (28Mb |
| 3574 | of grammar file) bison is killed by my system, at 2000 (12Mb) bison |
| 3575 | passes, but produces negative #line number, once fixed, GCC is |
| 3576 | killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of |
| 3577 | C), it passes. |
| 3578 | * src/state.h (state_h): Code input lines on ints, not shorts. |
| 3579 | |

| 3592 | * src/output.c (output_table_data): Return the longest number. |
| 3593 | (prepare_tokens): Output `token_number_max'). |
| 3594 | * data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type): |
| 3595 | New. |
| 3596 | Use them to define yy_token_number_type/TokenNumberType. |
| 3597 | Use this type for yytranslate. |
| 3598 | * tests/torture.at (Big triangle): Push the limit from 124 to |
| 3599 | 253. |
| 3600 | * tests/regression.at (Web2c Actions): Adjust. |

| 3702 | to reorder ritem itself. |
| 3703 | |
| 3704 | * src/reduce.c (reduce_grammar_tables): Don't sort RITEM. |
| 3705 | |
| 3706 | 2002-04-07 Akim Demaille <akim@epita.fr> |

| 3727 | * src/LR0.c (new_state): Display `nstates' as the name of the |
| 3728 | newly created state. |

| 3730 | Be sure to distinguish the initial from the final state. |
| 3731 | (new_states): Create the itemset of the initial state, and use |
| 3732 | new_state. |
| 3733 | * src/closure.c (closure): Now that the initial state has its |

| 3735 | creating `ruleset'. |
| 3736 | |
| 3737 | As a result, now the rule 0, reducing to $axiom, is visible in the |
| 3738 | outputs. Adjust the test suite. |

| 3770 | the end of `rules', and count them out of `nrules'. |
| 3771 | (reduce_output, dump_grammar): Adjust. |
| 3772 | * src/print.c (print_grammar): It is no longer needed to check for |
| 3773 | the usefulness of a rule, as useless rules are beyond `nrules + 1'. |
| 3774 | * tests/reduce.at (Reduced Automaton): New test. |
| 3775 | |
| 3776 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 3777 | |
| 3778 | * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a |
| 3779 | lacking `+ 1' to nrules, Bison reported as useless a token if it |
| 3780 | was used solely to set the precedence of the last rule... |
| 3781 | |
| 3782 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 3783 | |
| 3784 | * data/bison.c++, data/bison.simple: Don't output the current file |

| 4123 | 2002-02-07 Robert Anisko <robert@lrde.epita.fr> |
| 4124 | |
| 4125 | * data/bison.c++: Replace some direct m4 expansions by constants. Be |
| 4126 | more consistent when naming methods and variables. Put preprocessor |
| 4127 | directives around tables only needed for debugging. |
| 4128 | |
| 4129 | 2002-02-07 Robert Anisko <robert@lrde.epita.fr> |
| 4130 | |
| 4131 | * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in |
| 4132 | C++ parsers. |
| 4133 | (yy::b4_name::parse): Use print_. |
| 4134 | |
| 4135 | 2002-02-07 Robert Anisko <robert@lrde.epita.fr> |
| 4136 | |
| 4137 | * data/bison.c++ (yy::b4_name::parse): Error recovery is back. |
| 4138 | |
| 4139 | 2002-02-07 Robert Anisko <robert@lrde.epita.fr> |
| 4140 | |
| 4141 | * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in |

| 4143 | (yy::b4_name::parse): Build verbose error messages, and use error_. |
| 4144 | |
| 4145 | 2002-02-06 Robert Anisko <robert@lrde.epita.fr> |
| 4146 | |
| 4147 | * data/bison.c++: Fix m4 quoting in comments. |
| 4148 | |
| 4149 | 2002-02-06 Robert Anisko <robert@lrde.epita.fr> |
| 4150 | |
| 4151 | * data/bison.c++: Adjust the parser code. Fix some muscles that were |
| 4152 | not expanded by m4. |
| 4153 | |
| 4154 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 4155 | |
| 4156 | * data/bison.c++: Adjust to the M4 back end. |
| 4157 | More is certainly needed. |
| 4158 | |
| 4159 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 4160 | |
| 4161 | Give a try to M4 as a back end. |
| 4162 | |
| 4163 | * lib/readpipe.c: New, from wdiff. |
| 4164 | * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and |
| 4165 | BISON_HAIRY. |
| 4166 | * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS |
| 4167 | specific values. Now it is m4 that performs the lookup. |
| 4168 | * src/parse-skel.y: Remove. |
| 4169 | * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New. |
| 4170 | * src/output.c (actions_output, guards_output) |
| 4171 | (token_definitions_output): No longer keeps track of the output |
| 4172 | line number, hence remove the second argument. |
| 4173 | (guards_output): Check against the guard member of a rule, not the |
| 4174 | action member. |
| 4175 | Adjust callers. |
| 4176 | (output_skeleton): Don't look for the skeleton location, let m4 do |
| 4177 | that. |
| 4178 | Create `/tmp/muscles.m4'. This is temporary, a proper temporary |
| 4179 | file will be used. |
| 4180 | Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton. |
| 4181 | (prepare): Given that for the time being changesyntax is not |
| 4182 | usable in M4, rename the muscles using `-' to `_'. |
| 4183 | Define `defines_flag', `output_parser_name' and `output_header_name'. |
| 4184 | * src/output.h (actions_output, guards_output) |
| 4185 | (token_definitions_output): Adjust prototypes. |
| 4186 | * src/scan-skel.l: Instead of scanning the skeletons, it now |
| 4187 | processes the output of m4: `__oline__' and `#output'. |
| 4188 | * data/bison.simple: Adjust to be used by M4(sugar). |
| 4189 | * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up |
| 4190 | to date. |
| 4191 | * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR' |
| 4192 | instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'. |
| 4193 | * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New, |
| 4194 | shamelessly stolen from CVS Autoconf. |
| 4195 | |
| 4196 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 4197 | |
| 4198 | * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version. |
| 4199 | * configure.in: Check for the declarations of free and malloc. |
| 4200 | * src/muscle_tab.c: Adjust. |
| 4201 | |
| 4202 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 4203 | |
| 4204 | * src/muscle_tab.c (muscle_init): Don't default to NULL muscle |
| 4205 | which have no values. |
| 4206 | |
| 4207 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 4208 | |
| 4209 | * src/bison.simple, src/bison.hairy, src/bison.c++: Move to... |
| 4210 | * data/: here. |
| 4211 | |
| 4212 | 2002-01-29 Paul Eggert <eggert@twinsun.com> |
| 4213 | |
| 4214 | * src/bison.simple (YYSIZE_T): Do not define merely because |
| 4215 | YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined. |
| 4216 | On some platforms, <alloca.h> does not declare YYSTD (size_t). |
| 4217 | |
| 4218 | 2002-01-27 Akim Demaille <akim@epita.fr> |
| 4219 | |
| 4220 | Fix `%nonassoc and eof'. |
| 4221 | |
| 4222 | * src/state.c (errs_dup): Aaaah! The failure was due to bytes |
| 4223 | which were not properly copied! Replace |
| 4224 | memcpy (res->errs, src->errs, src->nerrs); |
| 4225 | with |
| 4226 | memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0])); |
| 4227 | !!! |
| 4228 | * tests/regression.at (%nonassoc and eof): Adjust to newest |
| 4229 | Autotest: `.' is not in the PATH. |
| 4230 | |
| 4231 | 2002-01-27 Akim Demaille <akim@epita.fr> |
| 4232 | |
| 4233 | * tests/sets.at (AT_EXTRACT_SETS): New. |
| 4234 | (Nullable): Use it. |
| 4235 | (Firsts): New. |
| 4236 | |
| 4237 | 2002-01-26 Akim Demaille <akim@epita.fr> |
| 4238 | |
| 4239 | * tests/actions.at, tests/calc.at, tests/headers.at, |
| 4240 | * tests/torture.at: Adjust to the newest Autotest which no longer |
| 4241 | forces `.' in the PATH. |
| 4242 | |
| 4243 | 2002-01-25 Akim Demaille <akim@epita.fr> |
| 4244 | |
| 4245 | * tests/regression.at (%nonassoc and eof): New. |
| 4246 | Suggested by Robert Anisko. |
| 4247 | |
| 4248 | 2002-01-24 Akim Demaille <akim@epita.fr> |
| 4249 | |
| 4250 | Bison dumps core when trying to complain about broken input files. |
| 4251 | Reported by Cris van Pelt. |
| 4252 | |
| 4253 | * src/lex.c (parse_percent_token): Be sure to set token_buffer. |
| 4254 | * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge |
| 4255 | into... |
| 4256 | (Invalid inputs): Strengthen: exercise parse_percent_token. |
| 4257 | |
| 4258 | 2002-01-24 Robert Anisko <robert.anisko@epita.fr> |
| 4259 | |
| 4260 | * src/Makefile.am: Add bison.c++. |
| 4261 | * src/bison.c++: New skeleton. |
| 4262 | |
| 4263 | 2002-01-21 Paolo Bonzini <bonzini@gnu.org> |
| 4264 | |
| 4265 | * po/it.po: New. |
| 4266 | |
| 4267 | 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net> |
| 4268 | |
| 4269 | * src/files.c (skeleton_find) [MSDOS]: Fix cp definition. |
| 4270 | |
| 4271 | 2002-01-20 Marc Autret <marc@gnu.org> |
| 4272 | |
| 4273 | * src/files.c (compute_output_file_names): Fix |
| 4274 | |
| 4275 | 2002-01-20 Marc Autret <marc@gnu.org> |
| 4276 | |
| 4277 | * tests/output.at: New test. |
| 4278 | * src/files.c (compute_base_names): Don't map extensions when |
| 4279 | the YACC flag is set, use defaults. |
| 4280 | Reported by Evgeny Stambulchik. |
| 4281 | |
| 4282 | 2002-01-20 Marc Autret <marc@gnu.org> |
| 4283 | |
| 4284 | * src/system.h: Need to define __attribute__ away for non-GCC |
| 4285 | compilers as well (i.e. the vendor C compiler). |
| 4286 | Suggested by Albert Chin-A-Young. |
| 4287 | |
| 4288 | 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be> |
| 4289 | |
| 4290 | * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the |
| 4291 | canonical definition. |
| 4292 | * src/system.h: Use the canonical definition for PARAMS (avoids |
| 4293 | a conflict with the macro from lib/hash.h). |
| 4294 | |
| 4295 | 2002-01-11 Akim Demaille <akim@epita.fr> |
| 4296 | |
| 4297 | * configure.in: Use AC_FUNC_STRNLEN. |
| 4298 | Fixes the failures observed on AIX 4.3 by H.Merijn Brand. |
| 4299 | |
| 4300 | 2002-01-09 Akim Demaille <akim@epita.fr> |
| 4301 | |
| 4302 | * src/files.c, src/files.h (output_infix): New. |
| 4303 | (tab_extension): Remove. |
| 4304 | (compute_base_names): Compute the former, drop the latter. |
| 4305 | * src/output.c (prepare): Insert the muscles `output-infix', and |
| 4306 | `output-suffix'. |
| 4307 | * src/parse-skel.y (string, string.1): New. |
| 4308 | (section.header): Use it. |
| 4309 | (section.yacc): Remove. |
| 4310 | (prefix): Remove too. |
| 4311 | * src/scan-skel.l: Adjust. |
| 4312 | * src/bison.simple, src/bison.hairy: Adjust. |
| 4313 | |
| 4314 | 2002-01-09 Akim Demaille <akim@epita.fr> |
| 4315 | |
| 4316 | * configure.in (WERROR_CFLAGS): Compute it. |
| 4317 | * src/Makefile.am (CFLAGS): Pass it. |
| 4318 | * tests/atlocal.in (CFLAGS): Idem. |
| 4319 | * src/files.c: Fix a few warnings. |
| 4320 | (get_extension_index): Remove, unused. |
| 4321 | |
| 4322 | 2002-01-08 Akim Demaille <akim@epita.fr> |
| 4323 | |
| 4324 | * src/getargs.c (AS_FILE_NAME): New. |
| 4325 | (getargs): Use it to convert DOSish file names. |
| 4326 | * src/files.c (base_name): Rename as full_base_name to avoid |
| 4327 | clashes with `base_name ()'. |
| 4328 | (filename_split): New. |
| 4329 | (compute_base_names): N-th rewrite, using filename_split. |
| 4330 | |
| 4331 | 2002-01-08 Akim Demaille <akim@epita.fr> |
| 4332 | |
| 4333 | * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c: |
| 4334 | New, stolen from the Fileutils 4.1. |
| 4335 | * lib/Makefile.am (libbison_a_SOURCES): Adjust. |
| 4336 | * configure.in: Check for the presence of memrchr, and of its |
| 4337 | prototype. |
| 4338 | |
| 4339 | 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be> |
| 4340 | |
| 4341 | * lib/hash.h (__P): Added definition for this macro. |
| 4342 | * src/Makefile.am: Add parse-skel.c and scan-skel.c to |
| 4343 | BUILT_SOURCES, to ensure they are generated first. |
| 4344 | * src/parse-skel.y: Use YYERROR_VERBOSE instead of |
| 4345 | %error-verbose to allow bootstrapping with bison 1.30x. |
| 4346 | |
| 4347 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 4348 | |
| 4349 | * src/reader.c (parse_braces): Don't fetch the next char, the |
| 4350 | convention is to fetch on entry. |
| 4351 | * tests/torture.at (GNU Cim Grammar): Reintroduce their weird |
| 4352 | 'switch' without a following semicolon. |
| 4353 | * tests/regression.at (braces parsing): New. |
| 4354 | |
| 4355 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 4356 | |
| 4357 | Bison is dead wrong in its RR conflict reports. |
| 4358 | |
| 4359 | * tests/torture.at (GNU Cim Grammar): New. |
| 4360 | * src/conflicts.c (count_rr_conflicts): Fix. |
| 4361 | |
| 4362 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 4363 | |
| 4364 | Creating package.m4 from configure.ac causes too many problems. |
| 4365 | |
| 4366 | * tests/Makefile.am (package.m4): Create it by hand, |
| 4367 | AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf. |
| 4368 | |
| 4369 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 4370 | |
| 4371 | * src/Makefile.am (bison_SOURCES): Add parse-skel.h and |
| 4372 | skeleton.h. |
| 4373 | |
| 4374 | 2002-01-04 Paul Eggert <eggert@twinsun.com> |
| 4375 | |
| 4376 | * doc/bison.texinfo (Debugging): |
| 4377 | Remove YYSTDERR; it's no longer defined or used. |
| 4378 | Also, s/cstdio.h/cstdio/. |
| 4379 | |
| 4380 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 4381 | |
| 4382 | * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf. |
| 4383 | |
| 4384 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 4385 | |
| 4386 | * src/parse-skel.y (process_skeleton): Don't bind the parser's |
| 4387 | tracing code to --trace, wait for a better --trace option, with |
| 4388 | args. |
| 4389 | |
| 4390 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 4391 | |
| 4392 | * src/bison.simple (YYSTDERR): Remove, replace `stderr'. |
| 4393 | The ISO C++ standard is extremely clear about it: stderr is |
| 4394 | considered a macro, not a regular symbol (see table 94 `Header |
| 4395 | <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files). |
| 4396 | Therefore std:: does not apply to it. It still does with fprintf. |
| 4397 | Also, s/cstdio.h/cstdio/. |
| 4398 | |
| 4399 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 4400 | |
| 4401 | * lib/quotearg.c: Use `#include "..."' instead of `#include <...>' |
| 4402 | for non system headers. |
| 4403 | |
| 4404 | 2002-01-02 Akim Demaille <akim@epita.fr> |
| 4405 | |
| 4406 | Equip the skeleton chain with location tracking, runtime trace, |
| 4407 | pure parser and scanner. |
| 4408 | |
| 4409 | * src/parse-skel.y: Request a pure parser, locations, and prefix |
| 4410 | renaming. |
| 4411 | (%union): Having several members with the same type does not help |
| 4412 | type mismatches, simplify. |
| 4413 | (YYPRINT, yyprint): New. |
| 4414 | (yyerror): ``Rename'' (there is a #define yyerror skel_error) as... |
| 4415 | (skel_error): this. |
| 4416 | Handle locations. |
| 4417 | * src/scan-skel.l: Adjust to these changes. |
| 4418 | * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP) |
| 4419 | (LOCATION_PRINT, skel_control_t): New. |
| 4420 | |
| 4421 | 2001-12-30 Akim Demaille <akim@epita.fr> |
| 4422 | |
| 4423 | * src/parse-skel.y: Get rid of the shift/reduce conflict: |
| 4424 | replace `gb' with BLANKS. |
| 4425 | * src/scan-skel.l: Adjust. |
| 4426 | |
| 4427 | 2001-12-30 Akim Demaille <akim@epita.fr> |
| 4428 | |
| 4429 | * src/system.h: We don't need nor want bcopy. |
| 4430 | Throw away MS-DOS crap: we don't need getpid. |
| 4431 | * configure.in: We don't need strndup. It was even causing |
| 4432 | problems: because Flex includes the headers *before* us, |
| 4433 | _GNU_SOURCE is not defined by config.h, and therefore strndup was |
| 4434 | not visible. |
| 4435 | * lib/xstrndup.c: New. |
| 4436 | * src/scan-skel.l: Use it. |
| 4437 | Be sure to initialize yylval.muscle member when scanning a MUSCLE. |
| 4438 | * src/parse-skel.y: Use %directives instead of #defines. |
| 4439 | |
| 4440 | 2001-12-30 Akim Demaille <akim@epita.fr> |
| 4441 | |
| 4442 | * src/skeleton.h: New. |
| 4443 | * src/output.c (output_parser, output_master_parser): Remove, dead |
| 4444 | code. |
| 4445 | * src/output.h (get_lines_number, actions_output, guards_output) |
| 4446 | (token_definitions_output): Prototype them. |
| 4447 | * src/parse-skel.y: Add the license notice. |
| 4448 | Include output.h and skeleton.h. |
| 4449 | (process_skeleton): Returns void, and takes a single parameter. |
| 4450 | * src/scan-skel.l: Add the license notice. |
| 4451 | Include skeleton.h. |
| 4452 | Don't use %option yylineno: it seems that then Flex imagines |
| 4453 | REJECT has been used, and therefore it won't reallocate its |
| 4454 | buffers (which makes no other sense to me than a bug). It results |
| 4455 | in warnings for `unused: yy_flex_realloc'. |
| 4456 | |
| 4457 | 2001-12-30 Robert Anisko <robert.anisko@epita.fr> |
| 4458 | |
| 4459 | * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING) |
| 4460 | (MUSCLE_INSERT_PREFIX): ...to there. |
| 4461 | * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING) |
| 4462 | (MUSCLE_INSERT_PREFIX): Move from here... |
| 4463 | |
| 4464 | * src/bison.hairy: Add a section directive. Put braces around muscle |
| 4465 | names. This parser skeleton is still broken, but Bison should not |
| 4466 | choke on a bad muscle 'syntax'. |
| 4467 | * src/bison.simple: Add a section directive. Put braces around muscle |
| 4468 | names. |
| 4469 | |
| 4470 | * src/files.h (strsuffix, stringappend): Add declarations. |
| 4471 | (tab_extension): Add declaration. |
| 4472 | (short_base_name): Add declaration. |
| 4473 | |
| 4474 | * src/files.c (strsuffix, stringappend): No longer static. These |
| 4475 | functions are used in the skeleton parser. |
| 4476 | (tab_extension): New. |
| 4477 | (compute_base_names): Use the computations done in this function |
| 4478 | to guess if the generated parsers should have '.tab' in their |
| 4479 | names. |
| 4480 | (short_base_name): No longer static. |
| 4481 | |
| 4482 | * src/output.c (output_skeleton): New. |
| 4483 | (output): Disable call to output_master_parser, and give a try to |
| 4484 | a new skeleton handling system. |
| 4485 | (guards_output, actions_output): No longer static. |
| 4486 | (token_definitions_output, get_lines_number): No longer static. |
| 4487 | |
| 4488 | * configure.in: Use AM_PROG_LEX and AC_PROG_YACC. |
| 4489 | |
| 4490 | * src/Makefile.am (bison_SOURCES): Add scan-skel.l and |
| 4491 | parse-skel.y. |
| 4492 | |
| 4493 | * src/parse-skel.y: New file. |
| 4494 | * src/scan-skel.l: New file. |

| 4496 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4497 | |
| 4498 | %name-prefix is broken. |
| 4499 | |
| 4500 | * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy". |
| 4501 | Adjust all dependencies. |
| 4502 | * tests/headers.at (export YYLTYPE): Strengthen this test: use |
| 4503 | %name-prefix. |
| 4504 | |
| 4505 | Renaming yylval but not yylloc is not consistent. Now we do. |
| 4506 | |
| 4507 | * src/bison.simple: Prefix yylloc if used. |
| 4508 | * doc/bison.texinfo (Decl Summary): Document that. |
| 4509 | |
| 4510 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4511 | |
| 4512 | * doc/bison.texinfo: Promote `%long-directive' over |
| 4513 | `%long_directive'. |
| 4514 | Remove all references to fixed-output-files, yacc is enough. |
| 4515 | |
| 4516 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4517 | |
| 4518 | * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the |
| 4519 | user prologue. These are defaults. |
| 4520 | * tests/actions.at (Mid-rule actions): Make sure the user can |
| 4521 | define YYDEBUG and YYERROR_VERBOSE. |
| 4522 | |
| 4523 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4524 | |
| 4525 | * src/output.c (header_output): Don't forget to export YYLTYPE and |
| 4526 | yylloc. |
| 4527 | * tests/headers.at (export YYLTYPE): New, make sure it does. |
| 4528 | * tests/regression.at (%union and --defines, Invalid CPP headers): |
| 4529 | Move to... |
| 4530 | * tests/headers.at: here. |
| 4531 | |
| 4532 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4533 | |
| 4534 | * src/gram.h (rule_s): Member `assoc' is of type `associativity'. |
| 4535 | |
| 4536 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4537 | |
| 4538 | * tests/actions.at (Mid-rule actions): Output on a single line |
| 4539 | instead of several. |
| 4540 | |
| 4541 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4542 | |
| 4543 | * doc/bison.texinfo: Formatting changes. |
| 4544 | |
| 4545 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4546 | |
| 4547 | Don't store the token defs in a muscle, just be ready to output it |
| 4548 | on command. Now possible via `symbols'. Fixes a memory leak. |
| 4549 | |
| 4550 | * src/output.c (token_definitions_output): New. |
| 4551 | (output_parser, header_output): Use it. |
| 4552 | * src/reader.c (symbols_save): Remove. |
| 4553 | |
| 4554 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4555 | |
| 4556 | * src/bison.simple: Do not provide a default for YYSTYPE and |
| 4557 | YYLTYPE before the user's prologue. Otherwise it's hardly... a |
| 4558 | default. |
| 4559 | |
| 4560 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4561 | |
| 4562 | Mid-rule actions are simply... ignored! |
| 4563 | |
| 4564 | * src/reader.c (readgram): Be sure to attach mid-rule actions to |
| 4565 | the empty-rule associated to the dummy symbol, not to the host |
| 4566 | rule. |
| 4567 | * tests/actions.at (Mid-rule actions): New. |
| 4568 | |
| 4569 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4570 | |
| 4571 | Memory leak. |
| 4572 | |
| 4573 | * src/reader.c (reader): Free grammar. |
| 4574 | |
| 4575 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4576 | |
| 4577 | Memory leak. |
| 4578 | |
| 4579 | * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here, |
| 4580 | since it allocates it for each state, although only one is needed. |
| 4581 | (allocate_storage): Do it here. |
| 4582 | |
| 4583 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4584 | |
| 4585 | * src/options.h, src/options.c (create_long_option_table): Rename |
| 4586 | as... |
| 4587 | (long_option_table_new): this, with a clearer prototype. |
| 4588 | (percent_table): Remove, unused, |
| 4589 | * src/getargs.c (getargs): Adjust. |
| 4590 | |
| 4591 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4592 | |
| 4593 | * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c |
| 4594 | * src/print.c, src/print_graph.c, src/state.h: Rename state_table |
| 4595 | as states. |
| 4596 | |
| 4597 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4598 | |
| 4599 | * src/lalr.c (build_relations): Rename `states' as `states1'. |
| 4600 | Sorry, I don't understand exactly what it is, no better name... |
| 4601 | |
| 4602 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4603 | |
| 4604 | * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c |
| 4605 | * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c |
| 4606 | * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table |
| 4607 | as rules. |
| 4608 | |
| 4609 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4610 | |
| 4611 | * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long |
| 4612 | ago. |
| 4613 | |
| 4614 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4615 | |
| 4616 | * src/reader.c, src/reader.h (user_toknums): Remove. |
| 4617 | Adjust all users to use symbols[i]->user_token_number. |
| 4618 | |
| 4619 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4620 | |
| 4621 | * src/gram.c, src/gram.h (sprec, sassoc): Remove. |
| 4622 | Adjust all users to use symbols[i]->prec or ->assoc. |
| 4623 | |
| 4624 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4625 | |
| 4626 | * src/reader.c, src/reader.h (tags): Remove. |
| 4627 | Adjust all users to use symbols[i]->tag. |
| 4628 | |
| 4629 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4630 | |
| 4631 | * src/gram.h, src/gram.c (symbols): New, similar to state_table |
| 4632 | and rule_table. |
| 4633 | * src/reader.c (packsymbols): Fill this table. |
| 4634 | Drop sprec. |
| 4635 | * src/conflicts.c (resolve_sr_conflict): Adjust. |
| 4636 | * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a |
| 4637 | single table. |
| 4638 | Use symbols[i]->tag instead of tags[i]. |
| 4639 | |
| 4640 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4641 | |
| 4642 | * tests/calc.at (_AT_DATA_CALC_Y): Also use %union. |
| 4643 | In addition, put a comment in there, to replace... |
| 4644 | * tests/regression.at (%union and C comments): Remove. |
| 4645 | |
| 4646 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4647 | |
| 4648 | * tests/regression.at (Web2c Actions): Blindly move the actual |
| 4649 | output as expected output. The contents *seem* right to me, but I |
| 4650 | can't pretend reading perfectly parser tables... Nonetheless, all |
| 4651 | the other tests pass correctly, the table look OK, even though the |
| 4652 | presence of `$axiom' is to be noted: AFAICS it is useless (but |
| 4653 | harmless). |
| 4654 | |
| 4655 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4656 | |
| 4657 | * src/reader.c (readgram): Don't add the rule 0 if there were no |
| 4658 | rules read. In other words, add it _after_ having performed |
| 4659 | grammar sanity checks. |
| 4660 | Fixes the `tests/regression.at (Invalid input: 1)' Failure. |
| 4661 | |
| 4662 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4663 | |
| 4664 | * tests/regression.at (Web2c Report): Catch up: the rule 0 is now |
| 4665 | visible, and some states have now a different number. |
| 4666 | |
| 4667 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4668 | |
| 4669 | * src/reader.c (readgram): Bind the initial rule's lineno to that |
| 4670 | of the first rule. |
| 4671 | * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts): |
| 4672 | (Solved SR Conflicts): Adjust rule 0's line number. |
| 4673 | |
| 4674 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4675 | |
| 4676 | Fix the `GAWK Grammar' failure. |
| 4677 | |
| 4678 | * src/LR0.c (final_state): Initialize to -1 so that we do compute |
| 4679 | the reductions of the first state which was mistakenly confused |
| 4680 | with the final state because precisely final_state was initialized |
| 4681 | to 0. |
| 4682 | * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads, |
| 4683 | now noticed by Bison. |
| 4684 | * tests/regression.at (Rule Line Numbers): Adjust: state 0 does |
| 4685 | have a reduction on $default. |
| 4686 | |
| 4687 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4688 | |
| 4689 | * src/gram.c (ritem_print): Be sure to subtract 1 when displaying |
| 4690 | rule line numbers. |
| 4691 | * src/closure.c (print_closure): Likewise. |
| 4692 | * src/derives.c (print_derives): Likewise. |
| 4693 | * tests/sets.at (Nullable): Adjust: the rule numbers are correct |
| 4694 | now. |
| 4695 | |
| 4696 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4697 | |
| 4698 | * src/lalr.c (lookaheads_print): New. |
| 4699 | (lalr): Call it when --trace-flag. |
| 4700 | * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads |
| 4701 | are dumped. |
| 4702 | |
| 4703 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4704 | |
| 4705 | * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0', |
| 4706 | when walking through ritem, even via rule->rhs. |
| 4707 | * src/reduce.c (dump_grammar, useful_production, reduce_output) |
| 4708 | (useful_production, useless_nonterminals): Likewise. |
| 4709 | (reduce_grammar_tables): Likewise, plus update nritems. |
| 4710 | * src/nullable.c (set_nullable): Likewise. |
| 4711 | * src/lalr.c (build_relations): Likewise. |
| 4712 | * tests/sets.at (Nullable): Adjust. |
| 4713 | Fortunately, now, the $axiom is no longer nullable. |
| 4714 | |
| 4715 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4716 | |
| 4717 | * src/LR0.c (generate_states): Use nritems, not nitems, nor using |
| 4718 | the 0-sentinel. |
| 4719 | * src/gram.c (ritem_longest_rhs): Likewise. |
| 4720 | * src/reduce.c (nonterminals_reduce): Likewise. |
| 4721 | * src/print_graph.c (print_graph): Likewise. |
| 4722 | * src/output.c (output_rule_data): Likewise. |
| 4723 | * src/nullable.c (set_nullable): Likewise. |
| 4724 | |
| 4725 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 4726 | |
| 4727 | * src/output.c: Comment changes. |
| 4728 | |
| 4729 | 2001-12-27 Paul Eggert <eggert@twinsun.com> |
| 4730 | |
| 4731 | * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special |
| 4732 | cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and |
| 4733 | Sparc, as they were causing more porting problems than the |
| 4734 | (minor) performance improvement was worth. |
| 4735 | |
| 4736 | Also, catch up with 1.31's YYSTD. |
| 4737 | |
| 4738 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4739 | |
| 4740 | * src/output.c (output_gram): Rely on nritems, not the |
| 4741 | 0-sentinel. See below. |
| 4742 | Use -1 as separator, not 0. |
| 4743 | * src/bison.simple (yyparse): Subtract 1 to the rule numbers. |
| 4744 | Rely on -1 as separator in yyrhs, instead of 0. |
| 4745 | * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue |
| 4746 | twice `Now at end of input', therefore there are two lines less to |
| 4747 | expect. |
| 4748 | |
| 4749 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4750 | |
| 4751 | * tests/regression.at (Unresolved SR Conflicts): |
| 4752 | (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes |
| 4753 | below. |
| 4754 | |
| 4755 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4756 | |
| 4757 | * src/LR0.c (new_state): Recognize the final state by the fact it |
| 4758 | is reached by eoftoken. |
| 4759 | (insert_start_shifting_state, insert_eof_shifting_state) |
| 4760 | (insert_accepting_state, augment_automaton): Remove, since now |
| 4761 | these states are automatically computed from the initial state. |
| 4762 | (generate_states): Adjust. |
| 4763 | * src/print.c: When reporting a rule number to the user, substract |
| 4764 | 1, so that the axiom rule is rule 0, and the first user rule is 1. |
| 4765 | * src/reduce.c: Likewise. |
| 4766 | * src/print_graph.c (print_core): For the time being, just as for |
| 4767 | the report, depend upon --trace-flags to dump the full set of |
| 4768 | items. |
| 4769 | * src/reader.c (readgram): Once the grammar read, insert the rule |
| 4770 | 0: `$axiom: START-SYMBOL $'. |
| 4771 | * tests/set.at: Adjust: rule 0 is now displayed, and since the |
| 4772 | number of the states has changed (the final state is no longer |
| 4773 | necessarily the last), catch up. |
| 4774 | |
| 4775 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4776 | |
| 4777 | Try to make the use of the eoftoken valid. Given that its value |
| 4778 | is 0 which was also used as a sentinel in ritem, (i) make sure >= 0 |
| 4779 | is used instead of > 0 where appropriate, (ii), depend upon nritems |
| 4780 | instead of the 0-sentinel. |
| 4781 | |
| 4782 | * src/gram.h, src/gram.c (nritems): New. |
| 4783 | Expected to be duplication of nitems, but for the time being... |
| 4784 | * src/reader.c (packgram): Assert nritems and nitems are equal. |
| 4785 | * src/LR0.c (allocate_itemsets, new_itemsets): Adjust. |
| 4786 | * src/closure.c (print_closure, print_fderives): Likewise. |
| 4787 | * src/gram.c (ritem_print): Likewise. |
| 4788 | * src/print.c (print_core, print_grammar): Likewise. |
| 4789 | * src/print_graph.c: Likewise. |
| 4790 | |
| 4791 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4792 | |
| 4793 | * src/main.c (main): If there are complains after grammar |
| 4794 | reductions, then output the report anyway if requested, then die. |
| 4795 | * src/symtab.c (bucket_new): Initialize `value' to -1, not 0. |
| 4796 | * src/reader.c (eoftoken): New. |
| 4797 | (parse_token_decl): If the token being defined has value `0', it |
| 4798 | is the eoftoken. |
| 4799 | (packsymbols): No longer hack `tags' to insert `$' by hand. |
| 4800 | Be sure to preserve the value of the eoftoken. |
| 4801 | (reader): Make sure eoftoken is defined. |
| 4802 | Initialize nsyms to 0: now eoftoken is created just like the others. |
| 4803 | * src/print.c (print_grammar): Don't special case the eof token. |
| 4804 | * src/regression.at: Adjust: `$' has value 0, not -1, which was a |
| 4805 | lie anyway, albeit pleasant. |
| 4806 | * tests/calc.at: Exercise error messages with eoftoken. |
| 4807 | Change the grammar so that empty input is invalid. |
| 4808 | Adjust expectations. |
| 4809 | When yyungeting, be sure to use a valid yylloc: use last_yylloc. |
| 4810 | |
| 4811 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4812 | |
| 4813 | * configure.in: Check the protos of strchr ans strspn. |
| 4814 | Replace strchr if needed. |
| 4815 | * src/system.h: Provide the protos of strchr, strspn and memchr if |
| 4816 | missing. |
| 4817 | * lib/strchr.c: New. |
| 4818 | * src/reader.c (symbols_save): Use strchr. |
| 4819 | |
| 4820 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4821 | |
| 4822 | * src/print.c, src/print_graph.c (escape): New. |
| 4823 | Use it to quote the TAGS outputs. |
| 4824 | * src/print_graph.c (print_state): Now errors are in red, and |
| 4825 | reductions in green. |
| 4826 | Prefer high to wide: output the state number on a line of its own. |
| 4827 | |
| 4828 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4829 | |
| 4830 | * src/state.h, src/state.c (reductions_new): New. |
| 4831 | * src/LR0.c (set_state_table): Let all the states have a |
| 4832 | `reductions', even if reduced to 0. |
| 4833 | (save_reductions): Adjust. |
| 4834 | * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust. |
| 4835 | * src/print.c (print_reductions, print_actions): Adjust. |
| 4836 | * src/output.c (action_row): Adjust. |
| 4837 | |
| 4838 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4839 | |
| 4840 | * src/state.h, src/state.c (errs_new, errs_dup): New. |
| 4841 | * src/LR0.c (set_state_table): Let all the states have an errs, |
| 4842 | even if reduced to 0. |
| 4843 | * src/print.c (print_errs, print_reductions): Adjust. |
| 4844 | * src/output.c (output_actions, action_row): Adjust. |
| 4845 | * src/conflicts.c (resolve_sr_conflict): Adjust. |
| 4846 | |
| 4847 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4848 | |
| 4849 | * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL. |
| 4850 | |
| 4851 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4852 | |
| 4853 | * src/conflicts.c, src/conflicts.h (print_reductions): Move to... |
| 4854 | * src/print.c: here. |
| 4855 | (lookaheadset, shiftset): New, used as additional storage by |
| 4856 | print_reductions. |
| 4857 | (print_results): Adjust. |
| 4858 | (print_shifts, print_gotos, print_errs): New, extracted from... |
| 4859 | (print_actions): here. |
| 4860 | * src/print_graph.c (print_actions): Remove dead code. |
| 4861 | |
| 4862 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4863 | |
| 4864 | * src/reader.c (copy_dollar, copy_at): Better checking of `n' in |
| 4865 | `$n' and `@n'. |
| 4866 | |
| 4867 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4868 | |
| 4869 | * src/lalr.c (add_lookback_edge): Use state_t instead of ints. |
| 4870 | (build_relations): Adjust. |
| 4871 | |
| 4872 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4873 | |
| 4874 | * src/lalr.c (set_goto_map): Remove a wrong but benign loop |
| 4875 | duplication. |
| 4876 | |
| 4877 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4878 | |
| 4879 | * src/reader.c (packgram): Catch nitems overflows. |
| 4880 | |
| 4881 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4882 | |
| 4883 | * src/files.c, src/files.h (guard_obstack): Remove. |
| 4884 | * src/output.c (output): Adjust. |
| 4885 | * src/reader.c (parse_braces): New, factoring... |
| 4886 | (copy_action, copy_guard): these two which are renamed as... |
| 4887 | (parse_action, parse_guard): these. |
| 4888 | As a voluntary consequence, using braces around guards is now |
| 4889 | mandatory. |
| 4890 | |
| 4891 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4892 | |
| 4893 | * src/gram.h (rule_t): `guard' and `guard_line' are new members. |
| 4894 | * src/reader.c (symbol_list): `guard' and `guard_line' are new |
| 4895 | members. |
| 4896 | (symbol_list_new): Adjust. |
| 4897 | (copy_action): action_line is the first line, not the last. |
| 4898 | (copy_guard): Just as for actions, store the `action' only, not |
| 4899 | the switch/case/break flesh. |
| 4900 | Don't parse the user action that might follow the guard, let... |
| 4901 | (readgram): do it, i.e., now, there can be an action after a |
| 4902 | guard. |
| 4903 | In other words the guard is just explicitly optional. |
| 4904 | (packgram): Adjust. |
| 4905 | * src/output.c (guards_output): New. |
| 4906 | (output_parser): Call it when needed. |
| 4907 | (output): Also free the guard and attrs obstacks. |
| 4908 | * src/files.c, src/files.h (obstack_save): Remove. |
| 4909 | (output_files): Remove. |
| 4910 | As a result, if one needs the former `.act' file, using an |
| 4911 | appropriate skeleton which requires actions and guards is now |
| 4912 | required. |
| 4913 | * src/main.c (main): Adjust. |
| 4914 | * tests/semantic.at: New. |
| 4915 | * tests/regression.at: Use `input.y' as input file name. |
| 4916 | Avoid 8+3 problems by requiring input.c when the test needs the |
| 4917 | parser. |
| 4918 | |
| 4919 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4920 | |
| 4921 | * src/reader.c (symbol_list_new): Be sure to initialize all the |
| 4922 | fields. |
| 4923 | |
| 4924 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4925 | |
| 4926 | All the hacks using a final pseudo state are now useless. |
| 4927 | |
| 4928 | * src/LR0.c (set_state_table): state_table holds exactly nstates. |
| 4929 | * src/lalr.c (nLA): New. |
| 4930 | (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it |
| 4931 | instead of lookaheadsp from the pseudo state (nstate + 1). |
| 4932 | |
| 4933 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4934 | |
| 4935 | * src/output.c (action_row, token_actions): Use a state_t instead |
| 4936 | of a integer, and nlookaheads instead of the following state's |
| 4937 | lookaheadsp. |
| 4938 | |
| 4939 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4940 | |
| 4941 | * src/conflicts.c (log_resolution, flush_shift) |
| 4942 | (resolve_sr_conflict, set_conflicts, solve_conflicts) |
| 4943 | (count_sr_conflicts, count_rr_conflicts, conflicts_output) |
| 4944 | (conflicts_print, print_reductions): Use a state_t instead of an |
| 4945 | integer when referring to a state. |
| 4946 | As much as possible, depend upon nlookaheads, instead of the |
| 4947 | `lookaheadsp' member of the following state (since lookaheads of |
| 4948 | successive states are successive, the difference between state n + 1 |
| 4949 | and n served as the number of lookaheads for state n). |
| 4950 | * src/lalr.c (add_lookback_edge): Likewise. |
| 4951 | * src/print.c (print_core, print_actions, print_state) |
| 4952 | (print_results): Likewise. |
| 4953 | * src/print_graph.c (print_core, print_actions, print_state) |
| 4954 | (print_graph): Likewise. |
| 4955 | * src/conflicts.h: Adjust. |
| 4956 | |
| 4957 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4958 | |
| 4959 | * src/bison.hairy: Formatting/comment changes. |
| 4960 | ANSIfy. |
| 4961 | Remove `register' indications. |
| 4962 | Add plenty of `static'. |
| 4963 | |
| 4964 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 4965 | |
| 4966 | * src/output.c (prepare): Drop the muscle `ntbase' which |
| 4967 | duplicates ntokens. |
| 4968 | * src/bison.simple: Formatting/comment changes. |
| 4969 | Use YYNTOKENS only, which is documented, but not YYNTBASE, which |
| 4970 | is an undocumented synonym. |
| 4971 | |
| 4972 | 2001-12-22 Akim Demaille <akim@epita.fr> |
| 4973 | |
| 4974 | * src/output.c (output_table_data): Change the prototype to use |
| 4975 | `int' for array ranges: some invocations do pass an int, not a |
| 4976 | short. |
| 4977 | Reported by Wayne Green. |
| 4978 | |
| 4979 | 2001-12-22 Akim Demaille <akim@epita.fr> |
| 4980 | |
| 4981 | Some actions of web2c.y are improperly triggered. |
| 4982 | Reported by Mike Castle. |
| 4983 | |
| 4984 | * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/. |
| 4985 | * tests/regression.at (Web2c): Rename as... |
| 4986 | (Web2c Report): this. |
| 4987 | (Web2c Actions): New. |
| 4988 | |
| 4989 | 2001-12-22 Akim Demaille <akim@epita.fr> |
| 4990 | |
| 4991 | Reductions in web2c.y are improperly reported. |
| 4992 | Reported by Mike Castle. |
| 4993 | |
| 4994 | * src/conflicts.c (print_reductions): Fix. |
| 4995 | * tests/regression.at (Web2c): New. |
| 4996 | |
| 4997 | 2001-12-18 Akim Demaille <akim@epita.fr> |
| 4998 | |
| 4999 | Some host fail on `assert (!"foo")', which expands to |
| 5000 | ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__)) |
| 5001 | Reported by Nelson Beebee. |
| 5002 | |
| 5003 | * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with |
| 5004 | `#define it_succeeded 0' and `assert (it_succeeded)'. |
| 5005 | |
| 5006 | 2001-12-17 Marc Autret <autret_m@epita.fr> |
| 5007 | |
| 5008 | * src/bison.simple: Don't hard code the skeleton line and filename. |
| 5009 | * src/output.c (output_parser): Rename 'line' as 'output_line'. |
| 5010 | New line counter 'skeleton_line' (skeleton-line muscle). |
| 5011 | |
| 5012 | 2001-12-17 Paul Eggert <eggert@twinsun.com> |
| 5013 | |
| 5014 | * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that |
| 5015 | YYDEBUG must be defined to a nonzero value. |
| 5016 | |
| 5017 | * src/bison.simple (yytname): Do not assume that the user defines |
| 5018 | YYDEBUG to a properly parenthesized expression. |
| 5019 | |
| 5020 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 5021 | |
| 5022 | * src/state.h (state_t): Rename lookaheads as lookaheadsp. |
| 5023 | nlookaheads is a new member. |
| 5024 | Adjust all users. |
| 5025 | * src/lalr.h (nlookaheads): Remove this orphan declaration. |
| 5026 | * src/lalr.c (initialize_lookaheads): Set nlookaheads for each |
| 5027 | state. |
| 5028 | |
| 5029 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 5030 | |
| 5031 | * src/files.h, src/files.c (open_files, close_files): Remove. |
| 5032 | * src/main.c (main): Don't open/close files, nor invoke lex_free, |
| 5033 | let... |
| 5034 | * src/reader.c (reader): Do it. |
| 5035 | |
| 5036 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 5037 | |
| 5038 | * src/conflicts.c (print_reductions): Formatting changes. |
| 5039 | |
| 5040 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 5041 | |
| 5042 | * src/conflicts.c (flush_shift): Also adjust lookaheadset. |
| 5043 | (flush_reduce): New. |
| 5044 | (resolve_sr_conflict): Adjust. |
| 5045 | |
| 5046 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 5047 | |
| 5048 | * src/output.c (output_obstack): Be static and rename as... |
| 5049 | (format_obstack): this, to avoid any confusion with files.c's |
| 5050 | output_obstack. |
| 5051 | * src/reader.h (muscle_obstack): Move to... |
| 5052 | * src/output.h: here, since it's defined in output.c. |
| 5053 | |
| 5054 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 5055 | |
| 5056 | * src/output.c (action_row, save_column, default_goto) |
| 5057 | (sort_actions, matching_state, pack_vector): Better variable |
| 5058 | locality. |
| 5059 | |
| 5060 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 5061 | |
| 5062 | * src/output.c: Various formatting changes. |
| 5063 | |
| 5064 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 5065 | |
| 5066 | * src/files.c (output_files): Free the output_obstack. |
| 5067 | * src/main.c (main): Call print and print_graph conditionally. |
| 5068 | * src/print.c (print): Work unconditionally. |
| 5069 | * src/print_graph.c (print_graph): Work unconditionally. |
| 5070 | * src/conflicts.c (log_resolution): Output only if verbose_flag. |
| 5071 | |
| 5072 | 2001-12-16 Marc Autret <autret_m@epita.fr> |
| 5073 | |
| 5074 | * src/output.c (actions_output): Fix. When we use %no-lines, |
| 5075 | there is one less line per action. |
| 5076 | |
| 5077 | 2001-12-16 Marc Autret <autret_m@epita.fr> |
| 5078 | |
| 5079 | * src/bison.simple: Remove a useless #line directive. |
| 5080 | s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'. |
| 5081 | * src/output.c (get_lines_number): New. |
| 5082 | (output_parser): Adjust, now takes care about the lines of a |
| 5083 | output muscles. |
| 5084 | Fix line numbering. |
| 5085 | (actions_output): Computes the number of lines taken by actions. |
| 5086 | (output_master_parser): Insert new skeleton which is the name of |
| 5087 | the output parser file name. |
| 5088 | |
| 5089 | 2001-12-15 Marc Autret <autret_m@epita.fr> |
| 5090 | |
| 5091 | * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility. |
| 5092 | |
| 5093 | 2001-12-15 Marc Autret <autret_m@epita.fr> |
| 5094 | |
| 5095 | * src/output.c (output_gram): Keep track of the hairy one. |
| 5096 | |
| 5097 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 5098 | |
| 5099 | Make `make distcheck' work. |
| 5100 | |
| 5101 | * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses |
| 5102 | system.h which uses libgettext.h. |
| 5103 | |
| 5104 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 5105 | |
| 5106 | * src/nullable.c (set_nullable): Useless rules must be skipped, |
| 5107 | otherwise, since we range over their symbols, we might look at a |
| 5108 | nonterminal which no longer ``exists'', i.e., it is not counted in |
| 5109 | `nvars', hence we overflow our arrays. |
| 5110 | |
| 5111 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 5112 | |
| 5113 | The header can also be produced directly, without any obstack! |
| 5114 | Yahoo! |
| 5115 | |
| 5116 | * src/files.c, src/files.h (defines_obstack): Remove. |
| 5117 | (compute_header_macro): Global. |
| 5118 | (defines_obstack_save): Remove. |
| 5119 | * src/reader.c (parse_union_decl): No longer output to |
| 5120 | defines_obstack: its content can be found in the `stype' muscle |
| 5121 | anyway. |
| 5122 | (output_token_translations): Merge into... |
| 5123 | (symbols_output): this. |
| 5124 | Rename as... |
| 5125 | (symbols_save): this. |
| 5126 | (reader): Adjust. |
| 5127 | * src/output.c (header_output): New. |
| 5128 | (output): Call it. |
| 5129 | |
| 5130 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 5131 | |
| 5132 | * src/reader.c (parse_union_decl): Instead of handling two obstack |
| 5133 | simultaneously, use one to define the `stype' muscle, and use the |
| 5134 | value of the latter to fill defines_obstack. |
| 5135 | (copy_comment): Remove. |
| 5136 | (copy_comment2): Work for a single obstack. |
| 5137 | Rename as... |
| 5138 | (copy_comment): this. |
| 5139 | |
| 5140 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 5141 | |
| 5142 | * src/lex.c, src/lex.h (xgetc): No longer static. |
| 5143 | * src/reader.c (parse_union_decl): Revamp. |
| 5144 | |
| 5145 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 5146 | |
| 5147 | Still making progress in separating Bison into (i) input, (ii) |
| 5148 | process, (iii) output: now we can directly output the parser file |
| 5149 | without using table_obstack at all. |
| 5150 | |
| 5151 | * src/files.c, src/files.h (table_obstack): Bye bye. |
| 5152 | (parser_file_name): New. |
| 5153 | * src/files.c (compute_output_file_names): Compute it. |
| 5154 | * src/output.c (actions_output, output_parser) |
| 5155 | (output_master_parser): To a file instead of an obstack. |
| 5156 | |
| 5157 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 5158 | |
| 5159 | Attach actions to rules, instead of pre-outputting them to |
| 5160 | actions_obstack. |
| 5161 | |
| 5162 | * src/gram.h (rule_t): action and action_line are new members. |
| 5163 | * src/reader.c (symbol_list): Likewise. |
| 5164 | (copy_action): Save the actions within the rule. |
| 5165 | (packgram): Save them in rule_table. |
| 5166 | * src/output.c (actions_output): New. |
| 5167 | (output_parser): Use it on `%%actions'. |
| 5168 | (output_rule_data): Don't free rule_table. |
| 5169 | (output): Do it. |
| 5170 | (prepare): Don't save the `action' muscle. |
| 5171 | * src/bison.simple: s/%%action/%%actions/. |
| 5172 | |
| 5173 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 5174 | |
| 5175 | * src/reader.c (copy_action): When --yacc, don't append a `;' |
| 5176 | to the user action: let it fail if lacking. |
| 5177 | Suggested by Arnold Robbins and Tom Tromey. |
| 5178 | |
| 5179 | 2001-12-14 Akim Demaille <akim@epita.fr> |
| 5180 | |
| 5181 | * src/lex.c (literalchar): Simply return the char you decoded, non |
| 5182 | longer mess around with obstacks and int pointers. |
| 5183 | Adjust all callers. |
| 5184 | |
| 5185 | 2001-12-14 Akim Demaille <akim@epita.fr> |
| 5186 | |
| 5187 | * src/lex.c (literalchar): Don't escape the special characters, |
| 5188 | just decode them, and keep them as char (before, eol was output as |
| 5189 | the 2 char string `\n' etc.). |
| 5190 | * src/output.c (output_rule_data): Use quotearg to output the |
| 5191 | token strings. |
| 5192 | |
| 5193 | 2001-12-13 Paul Eggert <eggert@twinsun.com> |
| 5194 | |
| 5195 | * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE): |
| 5196 | Do not infringe on the global user namespace when using C++. |
| 5197 | (YYFPRINTF, YYSTDERR): New macros, needed for the above. |
| 5198 | All uses of `fprintf' and `stderr' changed. |
| 5199 | |
| 5200 | * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR. |
| 5201 | |
| 5202 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 5203 | |
| 5204 | The computation of nullable is broken: it doesn't handle empty |
| 5205 | RHS's properly. |
| 5206 | |
| 5207 | * tests/torture.at (GNU AWK Grammar): New. |
| 5208 | * tests/sets.at (Nullable): New. |
| 5209 | * src/nullable.c (set_nullable): Instead of blindly looping over |
| 5210 | `ritems', loop over the rules, and then over their rhs's. |
| 5211 | |
| 5212 | Work around Autotest bugs. |
| 5213 | |
| 5214 | * src/warshall.c (bitmatrix_print): Don't use `+--+' as table |
| 5215 | frame, because Autotest understand lines starting with a `+' as |
| 5216 | traces from the shell. Then, they are not processed properly. |
| 5217 | Admittedly an Autotest bug, but we don't have time to wait for |
| 5218 | Autotest to catch up. |
| 5219 | * tests/regression.at (Broken Closure): Adjust to the new table |
| 5220 | frames. |
| 5221 | Move to... |
| 5222 | * tests/sets.at: here. |
| 5223 | |
| 5224 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 5225 | |
| 5226 | * src/closure.c (closure): Use nrules instead of playing tricks |
| 5227 | with BITS_PER_WORD. |
| 5228 | |
| 5229 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 5230 | |
| 5231 | * src/print.c (print_actions): Output the handling of `$' as the |
| 5232 | traces do: shifting the token EOF. Before EOF was treated as a |
| 5233 | nonterminal. |
| 5234 | * tests/regression.at: Adjust some tests. |
| 5235 | * src/print_graph.c (print_core): Complete the set of items via |
| 5236 | closure. The next-to-final and final states are still unsatisfying, |
| 5237 | but that's to be addressed elsewhere. |
| 5238 | No longer output the rule numbers, but do output the state number. |
| 5239 | A single loop for the shifts + gotos is enough, but picked a |
| 5240 | distinct color for each. |
| 5241 | (print_graph): Initialize and finalize closure. |
| 5242 | |
| 5243 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 5244 | |
| 5245 | * src/reader.c (readgram): Remove dead code, an strip useless |
| 5246 | braces. |
| 5247 | (get_type): Remove, unused. |
| 5248 | |
| 5249 | 2001-12-12 Akim Demaille <akim@epita.fr> |
| 5250 | |
| 5251 | * src/complain.h, src/complain.c: Remove error_one_per_line, rely |
| 5252 | on that of lib/error.c. |
| 5253 | |
| 5254 | 2001-12-12 Akim Demaille <akim@epita.fr> |
| 5255 | |
| 5256 | Some hosts don't like `/' in includes. |
| 5257 | |
| 5258 | * src/system.h: Include libgettext.h without qualifying the path. |
| 5259 | * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove |
| 5260 | $(top_srcdir). |
| 5261 | |
| 5262 | 2001-12-11 Marc Autret <autret_m@epita.fr> |
| 5263 | |
| 5264 | * src/output.c (output_parser): Remove useless muscle. |
| 5265 | |
| 5266 | 2001-12-11 Marc Autret <autret_m@epita.fr> |
| 5267 | |
| 5268 | * src/bison.simple: Remove #line just before %%epilogue. It |
| 5269 | is now handled in ... |
| 5270 | * src/reader.c (read_additionnal_code): Add the output of a |
| 5271 | #line for the epilogue. |
| 5272 | |
| 5273 | 2001-12-10 Marc Autret <autret_m@epita.fr> |
| 5274 | |
| 5275 | * src/reader.c (copy_definition): Re-use CPP-outed code which |
| 5276 | replace precedent remove. |
| 5277 | * src/bison.simple: Remove #line before %%prologue because |
| 5278 | %%input-line is wrong at this time. |
| 5279 | |
| 5280 | 2001-12-10 Marc Autret <autret_m@epita.fr> |
| 5281 | |
| 5282 | * src/reader.c (symbols_output): Clean up. |
| 5283 | * src/output.c (output_gram, output): Clean up. |
| 5284 | |
| 5285 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5286 | |
| 5287 | * src/lalr.c (initialize_lookaheads): New. Extracted from... |
| 5288 | * src/LR0.c (set_state_table): here. |
| 5289 | * src/lalr.c (lalr): Call it. |
| 5290 | |
| 5291 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5292 | |
| 5293 | * src/state.h (shifts): Remove the `number' member: shifts are |
| 5294 | attached to state, hence no longer need to be labelled with a |
| 5295 | state number. |
| 5296 | |
| 5297 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5298 | |
| 5299 | Now that states have a complete set of members, the linked list of |
| 5300 | shifts is useless: just fill directly the state's shifts member. |
| 5301 | |
| 5302 | * src/state.h (shifts): Remove the `next' member. |
| 5303 | * src/LR0.c (first_state, last_state): Remove. |
| 5304 | Adjust the callers. |
| 5305 | (augment_automaton): Don't look for the shifts that must be added |
| 5306 | a shift on EOF: it is those of the state we looked for! But now, |
| 5307 | since shifts are attached, it is no longer needed to looking |
| 5308 | merely by its id: its number. |
| 5309 | |
| 5310 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5311 | |
| 5312 | * src/LR0.c (augment_automaton): Better variable locality. |
| 5313 | Remove an impossible branch: if there is a state corresponding to |
| 5314 | the start symbol being shifted, then there is shift for the start |
| 5315 | symbol from the initial state. |
| 5316 | |
| 5317 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5318 | |
| 5319 | * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state' |
| 5320 | only when appropriate: when insert_start_shifting_state' is not |
| 5321 | invoked. |
| 5322 | * tests/regression.at (Rule Line Numbers): Adjust. |
| 5323 | |
| 5324 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5325 | |
| 5326 | * src/LR0.c (augment_automaton): Now that all states have shifts, |
| 5327 | merge the two cases addition shifts to the initial state. |
| 5328 | |
| 5329 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5330 | |
| 5331 | * src/lalr.c (set_state_table): Move to... |
| 5332 | * src/LR0.c: here. |
| 5333 | * src/lalr.c (lalr): Don't call it... |
| 5334 | * src/LR0.c (generate_states): do it. |
| 5335 | * src/LR0.h (first_state): Remove, only the table is used. |
| 5336 | |
| 5337 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5338 | |
| 5339 | * src/LR0.h (first_shift, first_reduction): Remove. |
| 5340 | * src/lalr.c: Don't use first_shift: find shifts through the |
| 5341 | states. |
| 5342 | |
| 5343 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5344 | |
| 5345 | * src/LR0.c: Attach shifts to states as soon as they are |
| 5346 | computed. |
| 5347 | * src/lalr.c (set_state_table): Instead of assigning shifts to |
| 5348 | state, just assert that the mapping was properly done. |
| 5349 | |
| 5350 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5351 | |
| 5352 | * src/LR0.c (insert_start_shift): Rename as... |
| 5353 | (insert_start_shifting_state): this. |
| 5354 | (insert_eof_shifting_state, insert_accepting_state): New. |
| 5355 | (augment_automaton): Adjust. |
| 5356 | Better locality of the variables. |
| 5357 | When looking if the start_symbol is shifted from the initial |
| 5358 | state, using `while (... symbol != start_symbol ...)' sounds |
| 5359 | better than `while (... symbol < start_symbol ...)': If fail |
| 5360 | to see how the order between symbols could be relevant! |
| 5361 | |
| 5362 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5363 | |
| 5364 | * src/getargs.h: Don't declare `spec_name_prefix' and |
| 5365 | `spec_file_prefix', declared by src/files.h. |
| 5366 | * src/files.c, src/files.h: Default for spec_name_prefix is "yy". |
| 5367 | * src/muscle_tab.c (muscle_init): Default prefix to NULL. |
| 5368 | * src/output.c (prepare): Adjust. |
| 5369 | * src/reader.c (symbols_output): Likewise. |
| 5370 | * src/vmsgetargs.c: Vaguely adjust, but who cares? |
| 5371 | |
| 5372 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5373 | |
| 5374 | * src/muscle_tab.c (muscle_init): NULL is a better default than |
| 5375 | `"0"'. |
| 5376 | |
| 5377 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5378 | |
| 5379 | * src/reader.c (reader): Calling symbols_output once is enough. |
| 5380 | |
| 5381 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5382 | |
| 5383 | Now that states have a complete set of members, the linked list of |
| 5384 | reductions is useless: just fill directly the state's reductions |
| 5385 | member. |
| 5386 | |
| 5387 | * src/state.h (struct reductions): Remove member `number' and |
| 5388 | `next'. |
| 5389 | * src/LR0.c (first_reduction, last_reduction): Remove. |
| 5390 | (save_reductions): Don't link the new reductions, store them in |
| 5391 | this_state. |
| 5392 | * src/lalr.c (set_state_table): No need to attach reductions to |
| 5393 | states, it's already done. |
| 5394 | * src/output.c (output_actions): No longer free the shifts, then |
| 5395 | the reductions, then the states: free all the states and their |
| 5396 | members. |
| 5397 | |
| 5398 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5399 | |
| 5400 | * src/options.c (OPTN, DRTV, BOTH): New. |
| 5401 | (option_table): Use them. |
| 5402 | |
| 5403 | * src/muscle_tab.c: Don't include xalloc.h and string.h: that's |
| 5404 | the job of system.h. |
| 5405 | * src/options.c: Don't include stdio.h and xalloc.h for the same |
| 5406 | reasons. |
| 5407 | |
| 5408 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5409 | |
| 5410 | * src/output.c (output, prepare): Make sure the values of the |
| 5411 | muscles `action' and `prologue' are 0-terminated. |
| 5412 | |
| 5413 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5414 | |
| 5415 | Clean up GCC warnings. |
| 5416 | |
| 5417 | * src/reader.c (copy_action): `buf' is not used. |
| 5418 | (parse_skel_decl): Be static. |
| 5419 | * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'. |
| 5420 | * src/options.h (create_long_option_table): Have a real prototype. |
| 5421 | * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete) |
| 5422 | (hash_delete_at): Return const void *. |
| 5423 | Adjust casts to preserve the const. |
| 5424 | |
| 5425 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5426 | |
| 5427 | * configure.in: Require 2.52g. |
| 5428 | M4 is not needed, but AUTOM4TE is. |
| 5429 | * m4/m4.m4: Remove. |
| 5430 | * tests/Makefile.am: Adjust. |
| 5431 | |
| 5432 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5433 | |
| 5434 | One structure for states is enough, even though theoretically |
| 5435 | there are LR(0) states and LALR(1) states. |
| 5436 | |
| 5437 | * src/lalr.h (state_t): Remove. |
| 5438 | (state_table): Be state_t **, not state_t *. |
| 5439 | * src/state.h (core, CORE_ALLOC): Rename as... |
| 5440 | (state_t, STATE_ALLOC): this. |
| 5441 | Add the LALR(1) members: shifts, reductions, errs. |
| 5442 | * src/LR0.c (state_table): Rename as... |
| 5443 | (state_hash): this, to avoid name clashes with the global |
| 5444 | `state_table'. |
| 5445 | * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c |
| 5446 | * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust. |
| 5447 | |
| 5448 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 5449 | |
| 5450 | Bison dumps core on bash.y. |
| 5451 | Reported by Pascal Bart. |
| 5452 | |
| 5453 | * src/warshall.c (bitmatrix_print): New. |
| 5454 | (TC): Use it. |
| 5455 | When performing a transitive closure R(i, j) && R(j, k) => R(i, k), |
| 5456 | j must be the outer loop. |
| 5457 | * tests/regression.at (Broken Closure): New. |
| 5458 | |
| 5459 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 5460 | |
| 5461 | * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and |
| 5462 | its argument. |
