| 1 | 2004-09-20 Akim Demaille <akim@epita.fr> |
| 2 | |
| 3 | * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a |
| 4 | clearer criterion to define it. |
| 5 | (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL. |
| 6 | When reducing on an empty RHS, use the latest stacked location as |
| 7 | location. |
| 8 | yylloc is not always available. |
| 9 | * data/glr.c: Likewise. |
| 10 | Also, honor initial-actions. |
| 11 | |
| 12 | 2004-09-20 Akim Demaille <akim@epita.fr> |
| 13 | |
| 14 | * data/yacc.c (YY_LOCATION_PRINT): New. |
| 15 | Define when we know YYLTYPE's structure, i.e., when the default |
| 16 | YYLLOC_DEFAULT is used. |
| 17 | * data/c.m4 (b4_yysymprint_generate): Use it. |
| 18 | * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial |
| 19 | value of the result. |
| 20 | (error_start_): Replace with... |
| 21 | (error_range_): this location array. |
| 22 | This allows to replace code relying on the implementation of |
| 23 | locations by portable code. |
| 24 | * data/yacc.c (yylerrsp): Replace with... |
| 25 | (yyerror_range): this. |
| 26 | Every time a token is popped, update yyerror_range[0], to have an |
| 27 | accurate location for the error token. |
| 28 | * data/glr.c (YY_LOCATION_PRINT): New. |
| 29 | (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT: |
| 30 | deference a pointer. |
| 31 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer |
| 32 | report the location in %printers. |
| 33 | |
| 34 | * src/scan-skel.l: Instead of abort, report error messages to ease |
| 35 | understanding skeleton scanning failures. |
| 36 | |
| 37 | 2004-09-16 Akim Demaille <akim@epita.fr> |
| 38 | |
| 39 | * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as... |
| 40 | (iterator, const_iterator): these, to be more in the C++ spirit. |
| 41 | Also, return reverse iterators so that when displaying the stack |
| 42 | we display its bottom first. |
| 43 | (Parser::stack_print_, Parser::reduce_print_): Match the messages |
| 44 | from yacc.c. |
| 45 | We should probably use vector here though. |
| 46 | |
| 47 | 2004-09-16 Akim Demaille <akim@epita.fr> |
| 48 | |
| 49 | Have more complete shift traces. |
| 50 | |
| 51 | * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT |
| 52 | to report Shifts instead of ad hoc YYDPRINTF invocations, |
| 53 | including for the error token. |
| 54 | * data/lalr1.cc (symprint_): Output the location. |
| 55 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't |
| 56 | output the location within the %printer. |
| 57 | Activate GLR tests, at least to make sure they compile properly. |
| 58 | They still don't pass though. |
| 59 | * tests/calc.at: Adjust expect verbose output, since now "Entering |
| 60 | state..." is on a different line than the "Shifting" message. |
| 61 | |
| 62 | 2004-09-08 Akim Demaille <akim@epita.fr> |
| 63 | |
| 64 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the |
| 65 | Bison directive from the Bison file to the invocation of this |
| 66 | macro, so that these directives are passed to |
| 67 | AT_BISON_OPTION_PUSHDEFS to get correct help macros. |
| 68 | Use these helping macros (e.g., AT_LOC, AT_VAL and so forth). |
| 69 | Move the AT_SETUP/AT_CLEANUP outside, to report as test title |
| 70 | the extra Bison directives instead of the whole series. |
| 71 | Change the grammar so that there are recoverable errors, and |
| 72 | unrecoverable errors. Now we can have the parser give up before |
| 73 | consuming the whole input. As a result we now can observe that |
| 74 | the lookahead is freed when needed. |
| 75 | Change the parser source to parse argv[1] instead of a hard coded |
| 76 | string. |
| 77 | Simplify yylex, and give a value and location to EOF. |
| 78 | Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that |
| 79 | passed directives already coded in the file. |
| 80 | Add some tests to check the location of "error". |
| 81 | For some tests, the C++ parser is correct, and not yacc.c. |
| 82 | For other tests, they provide different, but unsatisfying, values, |
| 83 | so keep the C++ value so that at least one parser is "correct" |
| 84 | according to the test suite. |
| 85 | (Actions after errors): Remove, this is subsumed by the |
| 86 | AT_CHECK_PRINTER_AND_DESTRUCTOR series. |
| 87 | |
| 88 | 2004-09-06 Akim Demaille <akim@epita.fr> |
| 89 | |
| 90 | * data/lalr1.cc: Adjust the indentation of the labels. |
| 91 | (Parser::pop): New. |
| 92 | Use it. |
| 93 | |
| 94 | 2004-09-06 Akim Demaille <akim@epita.fr> |
| 95 | |
| 96 | * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional |
| 97 | argument, an informative message. |
| 98 | Call YY_SYMBOL_PRINT. |
| 99 | Adjust all callers: integrate the associated YY_SYMBOL_PRINT. |
| 100 | * data/lalr1.cc (destruct_): Likewise. |
| 101 | In addition, no longer depend on b4_yysymprint_generate and |
| 102 | b4_yydestruct_generate to generate these functions, do it "by |
| 103 | hand". |
| 104 | |
| 105 | 2004-09-03 Akim Demaille <akim@epita.fr> |
| 106 | |
| 107 | * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was |
| 108 | invoked, yydestruct the lookahead. |
| 109 | * tests/calc.at (Calculator $1): Update the expected lengths of |
| 110 | traces: there is an added line for the discarded lookahead. |
| 111 | * doc/bison.texinfo (Destructor Decl): Some rewording. |
| 112 | Define "discarded" symbols. |
| 113 | |
| 114 | 2004-09-02 Akim Demaille <akim@epita.fr> |
| 115 | |
| 116 | * data/lalr1.cc (translate_, destruct_): No reason to be static. |
| 117 | |
| 118 | 2004-09-02 Akim Demaille <akim@epita.fr> |
| 119 | |
| 120 | * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used. |
| 121 | (YYDSYMPRINTF): Rename as... |
| 122 | (YY_SYMBOL_PRINT): this. |
| 123 | * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous |
| 124 | two. |
| 125 | Use it instead of direct symprint_ calls. |
| 126 | (yybackup): Tweak the "Now at end of input" case to match yacc.c's |
| 127 | one. |
| 128 | |
| 129 | 2004-09-02 Akim Demaille <akim@epita.fr> |
| 130 | |
| 131 | * data/lalr1.cc (b4_yysymprint_generate): New. |
| 132 | (symprint_): New member function, defined when YYDEBUG. |
| 133 | Use it consistently instead of token/nterm debugging output by |
| 134 | hand. |
| 135 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust |
| 136 | %printer calls to use cdebug_ when using lalr1.cc. |
| 137 | |
| 138 | 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com> |
| 139 | |
| 140 | * data/glr.c: Guard the declarations of yypstack and yypdumpstack |
| 141 | with #ifdef YYDEBUG. |
| 142 | |
| 143 | 2004-08-26 Akim Demaille <akim@epita.fr> |
| 144 | |
| 145 | * doc/bison.texinfo (Implementing Loops): Rename as... |
| 146 | (Implementing Gotos/Loops): this. |
| 147 | |
| 148 | 2004-08-13 Paul Eggert <eggert@cs.ucla.edu> |
| 149 | |
| 150 | Adjust to latest gnulib. |
| 151 | * bootstrap (gnulib_modules): Add xalloc-die. |
| 152 | Set LC_ALL=C so that file names sort consistently. |
| 153 | Prefer the gnulib copies of gettext.m4, glibc21.m4, |
| 154 | inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4, |
| 155 | uintmax_t.m4, ulonglong.m4. |
| 156 | (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4, |
| 157 | po.m4 since we are now using _gl.m4 instead. |
| 158 | |
| 159 | 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com> |
| 160 | |
| 161 | * src/scan-action.l: Remove. Scanning of semantic actions is |
| 162 | handled in scan-gram.l. |
| 163 | |
| 164 | 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com> |
| 165 | |
| 166 | * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup. |
| 167 | |
| 168 | * src/location.h (struct): The file member is a uniqstr. |
| 169 | (equal_boundaries): Use UNIQSTR_EQ for comparison. |
| 170 | |
| 171 | 2004-07-22 Paul Eggert <eggert@cs.ucla.edu> |
| 172 | |
| 173 | Fix bug with non-%union parsers that have printers or destructors, |
| 174 | which led to a Bison core dump. Reported by Peter Fales in |
| 175 | <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>. |
| 176 | |
| 177 | * data/c.m4 (b4_symbol_actions): Don't assume %union was used. |
| 178 | * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE, |
| 179 | not to our own type. |
| 180 | * src/output.c (symbol_destructors_output, symbol_printers_output): |
| 181 | Don't assume %union. |
| 182 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR, |
| 183 | AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument |
| 184 | UNION-FLAG. All callers changed. |
| 185 | (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union. |
| 186 | Use type char, not unsigned int, when declaring an array of char; |
| 187 | this lets us remove a cast. |
| 188 | (Printers and Destructors): Add non-%union test cases. |
| 189 | |
| 190 | 2004-06-21 Paul Eggert <eggert@cs.ucla.edu> |
| 191 | |
| 192 | * doc/bison.texinfo: Minor editorial changes, mostly to the new |
| 193 | GLR writeups. E.g., avoid frenchspacing and the future tense, |
| 194 | change "lookahead" to "look-ahead", and change "wrt" to "with |
| 195 | respect to". |
| 196 | |
| 197 | 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU> |
| 198 | |
| 199 | * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements): |
| 200 | New sections, split off from the GLR Parsers section. Put the new |
| 201 | Simple GLR Parser near the start of the GLR section, for clarity. |
| 202 | Rewrite connective text. |
| 203 | |
| 204 | 2004-06-21 Frank Heckenbach <frank@g-n-u.de> |

| 207 | |
| 208 | 2004-06-21 Paul Eggert <eggert@cs.ucla.edu> |
| 209 | |
| 210 | * NEWS, TODO, doc/bison.texinfo: |
| 211 | Use "look-ahead" instead of "lookahead", to be consistent. |
| 212 | * REFERENCES: Fix incorrect reference to DeRemer and Pennello, |
| 213 | while we're fixing "look-ahead". |
| 214 | * src/conflicts.c (shift_set): Renamed from shiftset. |

| 263 | |
| 264 | Spent a few hours checking out which prerequisite versions the |
| 265 | current sources actually require. I went all the way back to |
| 266 | Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated |
| 267 | a seemingly endless set of combinations of versions more recent |
| 268 | than that. The bottom line is that the current sources require |
| 269 | fairly recent versions of the build tools, and it'll be some work |
| 270 | to change this. |
| 271 | * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59. |
| 272 | (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8. |
| 273 | (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12. |
| 274 | Add comments explaining why those particular versions are |
| 275 | currently needed. |
| 276 | |
| 277 | * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug |
| 278 | in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in |
| 279 | <http://mail.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>. |
| 280 | |
| 281 | * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work |
| 282 | (it fails with a Autoconf-without-aclocal-m4 diagnostic). |
| 283 | |
| 284 | 2004-05-26 Paul Eggert <eggert@cs.ucla.edu> |
| 285 | |
| 286 | * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to |
| 287 | 0.11.5. Suggested by Bruno Haible. |
| 288 | * bootstrap: Remove gettext version checking. |
| 289 | |
| 290 | * doc/bison.texinfo (Decl Summary): Also mention that %union |
| 291 | can depend on prerequisite types. Problem reported by Tim |
| 292 | Van Holder. |
| 293 | |
| 294 | 2004-05-25 Paul Eggert <eggert@cs.ucla.edu> |
| 295 | |
| 296 | * README: Mention GNU m4 1.4 bugs and Akim's patched version. |
| 297 | * README-alpha: Don't tell people not to package this. |
| 298 | |
| 299 | * bootstrap: Don't assume $(...) works; use `...` instead. |
| 300 | Problem reported by Paul Hilfinger. Also, diagnose non-GNU |
| 301 | gettext better. |
| 302 | |
| 303 | * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's |
| 304 | put into the -d output file, and mention what to do if YYSTYPE is |
| 305 | defined as a macro. |
| 306 | |
| 307 | 2004-05-24 Paul Eggert <eggert@cs.ucla.edu> |
| 308 | |
| 309 | Undo change made earlier today: it caused autopoint to not bring |
| 310 | in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for |
| 311 | autopoint's. |
| 312 | |
| 313 | * bootstrap: Check that gettext version matches what's in |
| 314 | configure.ac. Warn users to ignore robots.txt ERROR 404. |
| 315 | * bootstrap: Undo today's earlier change (logged below). |
| 316 | * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise. |
| 317 | |
| 318 | The gettext version checking is causing more trouble than it's |
| 319 | curing; remove it. Problem reported by Paul Hilfinger. |
| 320 | |
| 321 | * bootstrap: Issue a warning that one can expect a message |
| 322 | 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'. |
| 323 | * configure.ac (AM_GNU_GETTEXT_VERSION): Remove. |
| 324 | |
| 325 | 2004-05-23 Paul Eggert <eggert@cs.ucla.edu> |

| 400 | 2004-04-28 Paul Eggert <eggert@twinsun.com> |
| 401 | |
| 402 | Get files from the gnulib and po repositories, instead of relying |
| 403 | on them being in our CVS. Upgrade to latest versions of gnulib |
| 404 | and Automake. |
| 405 | |
| 406 | * Makefile.am (SUBDIRS): Remove m4; Automake now does m4. |
| 407 | * bootstrap: Bootstrap from gnulib and po repositories. |
| 408 | Much of this code was stolen from GNU diff and GNU tar's bootstrap. |
| 409 | * README-cvs: Document these changes. Remove version numbers from |
| 410 | mentions of build tools, since they change so often. Mention Flex. |
| 411 | |
| 412 | * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg. |
| 413 | (gl_USE_SYSTEM_EXTENSIONS): Add. |
| 414 | (AC_GNU_SOURCE, AC_AIX, AC_MINIX): |
| 415 | Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS |
| 416 | does this for us. |
| 417 | (AC_ISC_POSIX): Remove; we no longer support this |
| 418 | ancient OS, as it gets in the way of latest Autoconf & gnulib. |
| 419 | (AC_HEADER_STDC): Remove: we now assume C89 or better. |
| 420 | (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS. |
| 421 | Do not check for C89 headers, except for locale.h which is used |
| 422 | by the Yacc library and must port to K&R hosts. |
| 423 | (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS. |
| 424 | Do not check for C89 functions, except for setlocale which is |
| 425 | used by the Yacc library. |
| 426 | (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed. |
| 427 | (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR, |

| 430 | gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC, |
| 431 | AM_GNU_GETTEXT): Remove; now done by: |
| 432 | (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us. |
| 433 | (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this |
| 434 | for us. |
| 435 | |
| 436 | * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap". |
| 437 | (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): |
| 438 | Define to empty, as gnulib.mk will do the rest for us. |
| 439 | ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this |
| 440 | for us. |
| 441 | (libbison_a_SOURCES): Define to $(lib_SOURCES) now. |
| 442 | (lib_SOURCES): New symbol, containing only the non-gnulib libs. |
| 443 | |
| 444 | * src/files.c: Include gnulib's xstrndup.h. |
| 445 | |
| 446 | * src/system.h (MALLOC): Use xnmalloc, for better overflow checking. |
| 447 | (REALLOC): Use xnrealloc, for likewise. |
| 448 | (xstrndup, stpcpy): Remove decls, as gnulib does this for us now. |
| 449 | (strnlen, memrchr): Remove decls; functions no longer used. |
| 450 | Include <stpcpy.h>. |
| 451 | |
| 452 | * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c, |

| 472 | po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po: |
| 473 | Remove, as these files are now generated automatically |
| 474 | by bootstrap or automake. |
| 475 | |
| 476 | * po/ChangeLog: Remove: all but one entry was a duplicate |
| 477 | of this file, and I moved that 2000-11-02 entry here. |
| 478 | |
| 479 | * config/.cvsignore: Add Makefile, depcomp, install-sh. |
| 480 | * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c, |

| 490 | xstrndup.h. |
| 491 | * m4/.cvsignore: Remove Makefile, Makefile.in. Add alloca.m4, |
| 492 | dirname.m4, dos.m4, error.m4, getopt.m4, hash.m4, mbrtowc.m4, |
| 493 | mbswidth.m4, obstack.m4, onceonly.m4, quote.m4, quotearg.m4, |
| 494 | stdbool.m4, stpcpy.m4, strnlen.m4, unlocked-io.m4, xalloc.m4. |

| 496 | * src/.cvsignore: Remove *_.c. |
| 497 | |
| 498 | |
| 499 | * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't |
| 500 | support it. (The latest stable gzip doesn't.) |
| 501 | |
| 502 | 2004-04-27 Paul Eggert <eggert@twinsun.com> |
| 503 | |
| 504 | * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this |
| 505 | case, as stos_ is now used by destructors due to the 2004-02-09 |
| 506 | change. |
| 507 | |
| 508 | Remove more K&R C support. |
| 509 | * lib/libiberty.y (PARAMS): Remove. All uses removed. |
| 510 | * lib/subpipe.c (errno): Remove decl. |
| 511 | Include <stdlib.h> unconditionally. |

| 513 | * src/complain.c (vfprintf, strerror): Remove. |
| 514 | * src/system.h: Include limits.h, stdlib.h, string.h, locale.h |
| 515 | unconditionally. |
| 516 | (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns. |
| 517 | Use latest Autoconf recommendations for including inttypes.h, stdint.h. |
| 518 | (strchr, strspn, memchr): Remove decls. |
| 519 | * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h |
| 520 | unconditionally. Do not declare perror. |

| 522 | unconditionally. |
| 523 | |
| 524 | * src/complain.c (_): Remove useless defn, as system.h defines this. |
| 525 | |
| 526 | * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed |
| 527 | with latest obstack.h. |
| 528 | * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args |
| 529 | to procedure types, as obstack.h now does that for us. |
| 530 | * lib/lbitset.c (lbitset_elt_alloc): Likewise. |
| 531 | |
| 532 | * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>, |
| 533 | so that this include file can stand alone. |
| 534 | * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h |
| 535 | does this now. Include subpipe.h first after config.h, to |
| 536 | test whether it can stand alone. |
| 537 | |
| 538 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't |
| 539 | declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the |
| 540 | unused declaration. |
| 541 | |
| 542 | * tests/synclines.at (%union synch line): Put a dummy member in |
| 543 | the union, because empty unions aren't allowed in C. Caught |
| 544 | by GCC 3.4.0. |
| 545 | |
| 546 | 2004-04-13 Jim Meyering <jim@meyering.net> |
| 547 | |
| 548 | * src/conflicts.c (conflicts_print): Correct format string typo: |
| 549 | use `%%' to produce literal `%'. (trivial change) |
| 550 | |
| 551 | 2004-03-30 Paul Eggert <eggert@twinsun.com> |
| 552 | |

| 591 | |
| 592 | 2004-03-25 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU> |
| 593 | |
| 594 | * src/parse-gram.y: Define PERCENT_EXPECT_RR. |
| 595 | (declaration): Replace expected_conflicts with expected_sr_conflicts. |
| 596 | Add %expect-rr rule. |
| 597 | |
| 598 | * src/scan-gram.l: Recognize %expect-rr. |
| 599 | |

| 616 | Add support for hex token numbers. Suggested by Odd Arild Olsen in |
| 617 | <http://mail.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>. |
| 618 | |
| 619 | * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor |
| 620 | in lalr1.cc. |
| 621 | * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers. |
| 622 | * src/scan-gram.l (scan_integer): New function. |
| 623 | ({int}): Use it. |
| 624 | (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers. |
| 625 | (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+, |
| 626 | handle_action_dollar, handle_action_at, convert_ucn_to_byte): |
| 627 | Say "long int", not "long", for uniformity with GNU style. |
| 628 | |
| 629 | 2004-02-25 Paul Eggert <eggert@twinsun.com> |
| 630 | |
| 631 | * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from |
| 632 | compilers. This fixes a problem with Intel's C++ compiler being |
| 633 | chatty, reported by Guido Trentalancia in |
| 634 | <http://mail.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>. |
| 635 | |
| 636 | 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org> |
| 637 | |

| 639 | |
| 640 | * data/lalr1.cc (b4_cxx_destruct_def): New macro. |
| 641 | (Parser::stos_): Define unconditionally. |
| 642 | (Parser::destruct_): New method. Generate its body with |
| 643 | b4_yydestruct_generate. |
| 644 | (Parser::error_start_): New attribute. |
| 645 | (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous |
| 646 | token which are discarded. |

| 648 | error_start_ when erroneous token are discarded. |
| 649 | (Parser::parse) <yyerrlab1>: Compute the location of the error |
| 650 | token so that it covers all the discarded tokens. |
| 651 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so |
| 652 | it can be called with `%skeleton "lalr1.cc"', and do that. |
| 653 | |
| 654 | 2004-02-02 Paul Eggert <eggert@twinsun.com> |
| 655 | |
| 656 | * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions |
| 657 | $(top_srcdir)/lib and ../lib. This fixes a bug reported |
| 658 | by Paul Hilfinger; the old INCLUDES value didn't mention ../lib. |
| 659 | There's no need to mention top_builddir since Automake does that |
| 660 | for us. |
| 661 | (INCLUDES): Remove, as Automake says it's obsolescent. |
| 662 | Contents migrated into AM_CPPFLAGS as described above. |
| 663 | * lib/Makefile.am (INCLUDES): Remove; obsolescent. |
| 664 | |
| 665 | 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU> |
| 666 | |
| 667 | * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token. |
| 668 | (yyreportSyntaxError): Handle case where lookahead token is |
| 669 | YYEMPTY. |
| 670 | |
| 671 | 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU> |
| 672 | |
| 673 | * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that |
| 674 | resulting parsers are compilable with C++. |
| 675 | |
| 676 | 2003-12-23 Paul Eggert <eggert@twinsun.com> |
| 677 | |
| 678 | * config/depcomp, config/install-sh: Sync with Automake 1.8. |
| 679 | * src/output.c (output_skeleton): Rename local var. |
| 680 | * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in |
| 681 | Bison tokens, as this runs afoul of the 2003-10-07 change that |
| 682 | disallowed NUL bytes in character constants or string literals. |
| 683 | |
| 684 | * tests/local.at: Require Autoconf 2.59's Autotest. |
| 685 | * tests/testsuite.at: Don't include local.at, since we now assume |
| 686 | Autoconf 2.59 or later. Autoconf 2.59 had some problems with |
| 687 | including it. |
| 688 | * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring |
| 689 | multiple inclusion warnings. |
| 690 | |
| 691 | 2003-12-02 Akim Demaille <akim@epita.fr> |
| 692 | |

| 700 | |
| 701 | 2003-10-07 Paul Eggert <eggert@twinsun.com> |
| 702 | |
| 703 | * tests/Makefile.am (clean-local): Don't run 'testsuite --clean' |
| 704 | if testsuite doesn't exist. |
| 705 | |
| 706 | * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string |
| 707 | literals, unfortunately. |
| 708 | * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): |
| 709 | Complain about NUL bytes in character constants or string literals. |
| 710 | |
| 711 | 2003-10-05 Paul Eggert <eggert@twinsun.com> |
| 712 | |
| 713 | * NEWS: Don't document %no-default-prec, as it's still |
| 714 | too experimental. |
| 715 | * doc/bison.texinfo: Document %no-default-prec only if |
| 716 | the defaultprec flag is set. Normally it's not. |
| 717 | |
| 718 | 2003-10-04 Paul Eggert <eggert@twinsun.com> |
| 719 | |
| 720 | * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a |
| 721 | non-modifiable lvalue, instead of a modifiable one. |
| 722 | * doc/bison.texinfo (Actions): Document that $$ can |
| 723 | be assigned to. Do not claim that $$ and $N are |
| 724 | array element references: user code should not rely on this. |
| 725 | |
| 726 | 2003-10-01 Paul Eggert <eggert@twinsun.com> |
| 727 | |
| 728 | * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token. |
| 729 | (grammar_declaration): Use it. |
| 730 | * src/scan-gram.l: New token %no-default-prec. |
| 731 | * tests/conflicts.at: Revamp tests to use %no-default-prec. |
| 732 | * NEWS, doc/bison.texinfo: Document the above. |
| 733 | |
| 734 | 2003-10-01 Akim Demaille <akim@epita.fr> |
| 735 | |

| 765 | 2003-08-26 Akim Demaille <akim@epita.fr> |
| 766 | |
| 767 | * config/announce-gen (print_changelog_deltas): Neutralize "<#" as |
| 768 | "<\#" to avoid magic from Gnus when posting parts of this script. |
| 769 | |
| 770 | 2003-08-26 Akim Demaille <akim@epita.fr> |
| 771 | |
| 772 | * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from |
| 773 | (Parser::parse): here. |

| 785 | |
| 786 | When reducing initial empty rules, Bison parser read an initial |
| 787 | location that is not defined. This results in garbage, and that |
| 788 | affects Bison's own parser. Therefore we need (i) to extend Bison |
| 789 | to support a means to initialize this location, and (ii) to use |
| 790 | this CVS Bison to fix CVS Bison's parser. |
| 791 | |
| 792 | * src/reader.h, reader.c (epilogue_augment): Remove, replace |
| 793 | with... |
| 794 | * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this. |
| 795 | * src/parse-gram.y: Adjust. |
| 796 | (%initial-action): New. |
| 797 | (%error-verbose): Since we require CVS Bison, there is no reason |
| 798 | not to use it. |
| 799 | * src/scan-gram.l: Adjust. |
| 800 | * src/Makefile.am (YACC): New, to make sure we use our own parser. |
| 801 | * data/yacc.c (yyparse): Use b4_initial_action. |
| 802 | |
| 803 | 2003-08-25 Akim Demaille <akim@epita.fr> |
| 804 | |
| 805 | * doc/bison.texinfo: Don't promote stdout for error messages. |
| 806 | |
| 807 | 2003-08-25 Akim Demaille <akim@epita.fr> |
| 808 | |
| 809 | * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi. |
| 810 | From Alexandre Duret-Lutz. |
| 811 | |
| 812 | 2003-08-25 Akim Demaille <akim@epita.fr> |
| 813 | |
| 814 | Version 1.875c. |
| 815 | |
| 816 | 2003-08-25 Akim Demaille <akim@epita.fr> |
| 817 | |
| 818 | * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New. |
| 819 | Use them. |
| 820 | |
| 821 | 2003-08-25 Akim Demaille <akim@epita.fr> |
| 822 | |
| 823 | * data/lalr1.cc (Parser::reduce_print_): New. |
| 824 | Use it. |
| 825 | |
| 826 | 2003-08-25 Akim Demaille <akim@epita.fr> |
| 827 | |
| 828 | Have lalr1.cc catch with Paul Eggert's patch to fix the infinite |
| 829 | error recovery loops. This patch is based on |
| 830 | <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>. |
| 831 | Also, augment the similarity between lalr1.cc and yacc.c. |
| 832 | Note: the locations of error recovery rules are not correct yet. |
| 833 | |
| 834 | * data/lalr1.cc: Comment changes to augment the similarity between |
| 835 | lalr1.cc and yacc.c. |
| 836 | (YYERROR): Goto to yyerrorlab, not yyerrlab1. |
| 837 | (yyerrlab1): Remove, but where it used to be (now the bottom part of |
| 838 | yyerrlab), when hitting EOF, pop the whole stack here instead of |
| 839 | merely falling thru the default error handling mechanism. |
| 840 | (yyerrorlab): New label, with the old contents of YYERROR, |
| 841 | plus the following change: pop the stack of rhs corresponding |
| 842 | to the production that invoked YYERROR. That is how Yacc |
| 843 | behaves (required by POSIX). |
| 844 | * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to |
| 845 | fail. |
| 846 | |
| 847 | 2003-08-25 Akim Demaille <akim@epita.fr> |
| 848 | |
| 849 | Tune local.at so that people can "autom4te -l autotest calc.at -o |
| 850 | calc" for instance, to extract a sub test suite. |
| 851 | |
| 852 | * tests/testsuite.at: Move the initialization, Autotest version |
| 853 | requirement, and AT_TESTED invocation into... |
| 854 | * tests/local.at: here. |
| 855 | * tests/testsuite.at: Include it for compatibility with Autoconf |
| 856 | 2.57. |
| 857 | * tests/Makefile.am ($(TESTSUITE)): Report that the warning should |
| 858 | be ignore. |
| 859 | |
| 860 | 2003-08-04 Paul Eggert <eggert@twinsun.com> |
| 861 | |
| 862 | Rework code slightly to avoid gcc -Wtraditional warnings. |
| 863 | * data/glr.c (yyuserMerge): Return void, not YYSTYPE. |
| 864 | The returned value is now stored in *YY0. All callers changed. |
| 865 | * src/output.c (merge_output): Adjust to the above change. |
| 866 | |
| 867 | 2003-07-26 Paul Eggert <eggert@twinsun.com> |
| 868 | |
| 869 | * data/glr.c (YYASSERT): New macro. |
| 870 | (yyfillin, yydoAction, yyglrReduce, yysplitStack, |
| 871 | yyresolveStates, yyprocessOneStack): |
| 872 | Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'. |
| 873 | Derived from a suggestion by Frank Heckenbach. |
| 874 | |
| 875 | 2003-07-25 Paul Eggert <eggert@twinsun.com> |
| 876 | |
| 877 | * data/glr.c (yyglrReduce): Don't use C89 string concatenation, |
| 878 | for portability to K&R C (after ansi2knr, presumably). See |
| 879 | <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html> |
| 880 | by Frank Heckenbach, though I have omitted the structure-initialization |
| 881 | part of his glr-knr.diff patch since I recall that the Portable |
| 882 | C Compiler didn't require that change. |
| 883 | |
| 884 | Let the user specify how to allocate and free memory. |
| 885 | Derived from a suggestion by Frank Heckenbach in |
| 886 | <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>. |
| 887 | * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros. |
| 888 | All uses of free, malloc, realloc changed to use these macros, |
| 889 | and unnecessary casts removed. |
| 890 | * data/yacc.c (YYFREE, YYMALLOC): Likewise. |
| 891 | |
| 892 | 2003-07-06 Matthias Mann <MatthiasMann@gmx.de> |
| 893 | |
| 894 | * data/lalr1.cc (operator<<(std::ostream&, const Position&)): |
| 895 | use s.empty() rather than s == "" to test for empty string; see |
| 896 | <http://mail.gnu.org/archive/html/bison-patches/2003-07/msg00003.html> |
| 897 | (trivial change) |
| 898 | |
| 899 | 2003-06-25 Akim Demaille <akim@epita.fr> |
| 900 | |
| 901 | * config/depcomp, config/install-sh: Update from masters. |
| 902 | |
| 903 | 2003-06-20 Paul Eggert <eggert@twinsun.com> |
| 904 | |
| 905 | * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed, |
| 906 | and return properly parenthesized result. |
| 907 | * data/lalar1.cc (YYLLOC_DEFAULT): Likewise. |
| 908 | * data/yacc.c (YYLLOC_DEFAULT): Likewise. |
| 909 | Remove unnecessary parentheses from uses. |
| 910 | * doc/bison.texinfo (Location Default Action): Describe the |
| 911 | conventions for parentheses. |
| 912 | |
| 913 | 2003-06-19 Paul Eggert <eggert@twinsun.com> |
| 914 | |
| 915 | * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce, |
| 916 | yyreportTree): Do not assume that size_t is the same width as int, |
| 917 | when printing sizes. Print sizes using an unsigned format. |
| 918 | Problem reported by Frank Heckenbach in |
| 919 | <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>. |
| 920 | |
| 921 | Port to Forte Developer 7 C compiler. |
| 922 | * data/glr.c (struct YYLTYPE): If locations are not being used, |
| 923 | declare a single dummy member, as empty structs do not conform |
| 924 | to the C standard. |
| 925 | (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)"; |
| 926 | the Forte Developer 7 C compiler complains that end-of-loop |
| 927 | code is not reached. |
| 928 | |
| 929 | 2003-06-17 Paul Eggert <eggert@twinsun.com> |
| 930 | |
| 931 | * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to |
| 932 | avoid warnings from picky compilers about redefinition of PARAMS. |
| 933 | |
| 934 | 2003-06-17 Paul Eggert <eggert@twinsun.com> |
| 935 | |
| 936 | Version 1.875b. |
| 937 | |
| 938 | * NEWS: Document 1.875b. |
| 939 | |
| 940 | * lib/bbitset.h: Do not include config.h; that's the includer's job. |
| 941 | Do not include <sys/types.h>; shouldn't be needed on a C89 host. |
| 942 | * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard. |
| 943 | Don't use 'index' in comments, as it's a builtin fn on some hosts. |
| 944 | * lib/bitset_stats.c: Include gettext.h unconditionally, as |
| 945 | per recent gettext manual's suggestion. |
| 946 | * lib/ebitset.c (ebitset_resize, ebitset_unused_clear): |
| 947 | Use prototypes, not old-style definitions. |

| 970 | |
| 971 | * doc/bison.texinfo (How Can I Reset the Parser): Renamed from |
| 972 | `How Can I Reset @code{yyparse}', since texinfo does not allow |
| 973 | arbitrary @ in node names. |
| 974 | |
| 975 | * m4/Makefile.am (EXTRA_DIST): Add the following files, which |
| 976 | shouldn't be needed according to the gettext 0.12.1 documentation |
| 977 | but which seem to be needed anyway: codeset.m4 glibc21.m4 |
| 978 | intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4 |
| 979 | lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4. |

| 984 | |
| 985 | Upgrade to CVS gnulib. |
| 986 | * stdbool_.h: File renamed from stdbool.h.in. |
| 987 | * configure.ac (AM_STDBOOL_H): Invoke this instead of |
| 988 | AC_HEADER_STDBOOL. |
| 989 | (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests. |
| 990 | (AM_GNU_GETTEXT_VERSION): Update to 0.12.1. |

| 997 | lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4, |
| 998 | m4/quote.m4: Upgrade to today's gnulib. |
| 999 | |
| 1000 | * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL. |
| 1001 | (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails |
| 1002 | the tests right now. |
| 1003 | * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and |
| 1004 | yyerror are declared before use; C99 requires this. |
| 1005 | |
| 1006 | 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU> |
| 1007 | |
| 1008 | * data/glr.c (YYERROR): Update definition to reset yyerrState to 0 |
| 1009 | first. |
| 1010 | (yyrecoverSyntaxError): Correct the logic for setting and testing |
| 1011 | yyerrState. |
| 1012 | Correct comment on handling EOF. |
| 1013 | Allow states with only a default reduction, rather than failing |
| 1014 | (I can't quite reconstruct why these were not allowed before). |
| 1015 | |
| 1016 | Fixes to avoid problem that $-N rules in GLR parsers can cause |
| 1017 | buffer overruns, corrupting state. |
| 1018 | |
| 1019 | * src/output.c (prepare_rules): Output max_left_semantic_context |
| 1020 | definition. |
| 1021 | * src/reader.h (max_left_semantic_context): New variable declaration. |
| 1022 | * src/scan-gram.l (max_left_semantic_context): Define. |

| 1027 | |
| 1028 | Fixes to problems with location handling in GLR parsers reported by |
| 1029 | Frank Heckenbach (2003/06/05). |
| 1030 | |
| 1031 | * data/glr.c (YYLTYPE): Make trivial if locations not used. |
| 1032 | (YYRHSLOC): Add parentheses, and define only if locations used. |
| 1033 | (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if |
| 1034 | locations not used. |
| 1035 | (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp. |
| 1036 | (yydoAction): Remove redundant initialization of *yyvalp and *yylocp. |
| 1037 | |
| 1038 | * tests/cxx-type.at: Exercise location information; update tests |
| 1039 | to differentiate output with and without locations. |
| 1040 | Remove forward declarations of yylex and yyerror---caused errors |
| 1041 | because default YYLTYPE not yet defined. |
| 1042 | Change semantic actions to compute strings, rather than printing |
| 1043 | them directly (to test proper passing of semantics values). Change |
| 1044 | output to prefix notation and update test data and expected results. |
| 1045 | (yylex): Track locations. |
| 1046 | (stmtMerge): Return value rather than printing, and include arguments |
| 1047 | in value. |
| 1048 | |
| 1049 | 2003-06-03 Paul Eggert <eggert@twinsun.com> |
| 1050 | |
| 1051 | Avoid warnings generated by GCC 2.95.4 when Bison is |
| 1052 | configured with --enable-gcc-warnings. |
| 1053 | * data/lalr1.cc (yy::]b4_parser_class_name[::parse, |
| 1054 | yy::]b4_parser_class_name[::translate_, |
| 1055 | yy::Stack::operator[] (unsigned), |
| 1056 | yy::Stack::operator[] (unsigned) const, |
| 1057 | yy::Slice::operator[] (unsigned), |
| 1058 | yy::Slice::operator[] (unsigned) const): |
| 1059 | Rename local vars to avoid warnings. |
| 1060 | * tests/glr-regression.at (Improper handling of embedded actions |
| 1061 | and $-N in GLR parsers): Remove unused local variable from yylex. |
| 1062 | * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take |
| 1063 | (void) as arg when not pure, since we now assume C89 when building |
| 1064 | Bison. Pacify GCC by using parameter. |
| 1065 | |
| 1066 | 2003-06-02 Paul Eggert <eggert@twinsun.com> |
| 1067 | |
| 1068 | * data/lalr1.cc (yy::Position::lines, yy::Position::columns, |
| 1069 | yy::Location::lines, yy::Location::columns): Rename arguments |
| 1070 | to avoid shadowing; this removes a warning generated by GCC 3.3. |
| 1071 | |
| 1072 | 2003-06-01 Paul Eggert <eggert@twinsun.com> |
| 1073 | |
| 1074 | Don't pass C-only warning optins (e.g., -Wmissing-declarations) |
| 1075 | to g++, as GCC 3.3 complains if you do it. |
| 1076 | * configure.ac (WARNING_CXXFLAGS): New subst. Set it to |
| 1077 | everything that WARNING_CFLAGS has, except omit warnings |
| 1078 | not suitable for C++. |
| 1079 | (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]). |
| 1080 | * tests/atlocal.in (CXXFLAGS): New var. |
| 1081 | * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS. |
| 1082 | |
| 1083 | Fix a GLR parser bug I reported in February; see |
| 1084 | <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>. |
| 1085 | The problem was that GLR parsers did not conform to the C standard, |
| 1086 | because actions like { $1 = $2 + $3; } expanded to expressions |
| 1087 | that invoked YYFILL in separate subexpressions, and YYFILL assigned |
| 1088 | to a local variable. The C standard says that expressions |
| 1089 | like (var = f ()) + (var = f ()) have undefined behavior. |
| 1090 | Another problem was that GCC sometimes issues warnings that |
| 1091 | yyfill and its parameters are unused. |
| 1092 | |
| 1093 | * data/glr.c (yyfillin): Renamed from the old yyfill. Mark |
| 1094 | as possibly unused. |
| 1095 | (yyfill): New function. |
| 1096 | (YYFILL): Use it. |
| 1097 | (yyuserAction): Change type of yynormal to bool, so that it matches |
| 1098 | the new yyfill signature. Mark it as possibly unused. |
| 1099 | |
| 1100 | |
| 1101 | Follow up on a bug I reported in February, where a Bison-generated |
| 1102 | parser can loop. Provide a test case and a fix for yacc.c. I |
| 1103 | don't have a fix for lalr1.cc or for glr.c, unfortunately. |
| 1104 | The original bug report is in: |
| 1105 | <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00044.html> |
| 1106 | |
| 1107 | * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the |
| 1108 | macro's size was becoming unwieldy. |
| 1109 | (yyerrlab): Do not discard an empty lookahead symbol, as this |
| 1110 | might destroy garbage. |
| 1111 | (yyerrorlab): New label, with the old contents of YYERROR, |
| 1112 | plus the following change: pop the stack of rhs corresponding |
| 1113 | to the production that invoked YYERROR. That is how Yacc |
| 1114 | behaves, and POSIX requires this behavior. |
| 1115 | (yyerrlab1): Use YYPOPSTACK instead of its definiens. |
| 1116 | * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available. |
| 1117 | Define 'alarm' to do nothing if unistd.h is not available. |
| 1118 | Add a new rule "exp: '-' error;" to test the above change to |
| 1119 | data/yacc.c. Use 'alarm' to abort any test taking longer than |
| 1120 | 10 seconds, as it's probably looping. |
| 1121 | (AT_CHECK_CALC): Test recovery from error in new grammar rule. |
| 1122 | Also, the new yacc.c generates two fewer diagnostics for an |
| 1123 | existing test. |
| 1124 | |
| 1125 | 2003-05-24 Paul Eggert <eggert@twinsun.com> |
| 1126 | |
| 1127 | * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate |
| 1128 | YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined. |
| 1129 | This fixes a problem reported by John Bowman when the Compaq/HP |
| 1130 | Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM |
| 1131 | -ansi -Wall -gall). |
| 1132 | * data/yacc.c (union yyalloc): Likewise. |
| 1133 | (YYCOPY): Do not evaluate __GNUC__ unless it is defined. |
| 1134 | |
| 1135 | Switch from 'int' to 'bool' where that makes sense. |
| 1136 | |
| 1137 | * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p, |
| 1138 | abitset_subset_p, abitset_disjoint_p, abitset_and_cmp, |
| 1139 | abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or, |
| 1140 | abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp): |
| 1141 | Return or accept bool, not int. All callers changed. |
| 1142 | * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_, |
| 1143 | bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise. |
| 1144 | * lib/bitset.c (bitset_only_set_p, bitset_print, bitset_toggle_, |

| 1160 | lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp, |
| 1161 | lbitset_xor_cmp): Likewise. |
| 1162 | * lib/bbitset.h: Include <stdbool.h>. |
| 1163 | (struct bitset_vtable): The following members now return bool, not |
| 1164 | int: toggle, test, empty_p, disjoint_p, equal_p, subset_p, |
| 1165 | and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp, |
| 1166 | or_and_cmp). |
| 1167 | * src/conflicts.c (count_rr_conflicts): Likewise. |
| 1168 | * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int. |
| 1169 | All uses changed. |
| 1170 | * lib/ebitset.c (ebitset_obstack_init): Likewise. |
| 1171 | * lib/lbitset.c (lbitset_obstack_init): Likewise. |
| 1172 | * src/getargs.c (debug_flag, defines_flag, locations_flag, |
| 1173 | no_lines_flag, no_parser_flag, token_table_flag, yacc_flag, |
| 1174 | graph_flag): Likewise. |
| 1175 | * src/getargs.h (debug_flag, defines_flag, locations_flag, |
| 1176 | no_lines_flag, no_parser_flag, token_table_flag, yacc_flag, |
| 1177 | graph_flag): Likewise. |

| 1181 | * src/reader.h (typed): Likewise. |
| 1182 | * src/getargs.c (LOCATIONS_OPTION): New constant. |
| 1183 | (long_options, getargs): Use it. |
| 1184 | * src/lalr.c (build_relations): Use bool, not int. |
| 1185 | * src/nullable.c (nullable_compute): Likewise. |
| 1186 | * src/print.c (print_reductions): Likewise. |
| 1187 | * src/tables.c (action_row, pack_vector): Likewise. |
| 1188 | * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro. |
| 1189 | * src/output.c (prepare): Use it. |
| 1190 | * src/output.c (token_definitions_output, |
| 1191 | symbol_destructors_output, symbol_destructors_output): Use string, |
| 1192 | not boolean integer, to keep track of whether to output separator. |
| 1193 | * src/print_graph.c (print_core): Likewise. |
| 1194 | * src/state.c (state_rule_lookaheads_print): Likewise. |
| 1195 | |
| 1196 | * config/install-sh: Sync from automake 1.7.5. |
| 1197 | |
| 1198 | 2003-05-14 Paul Eggert <eggert@twinsun.com> |
| 1199 | |
| 1200 | * src/parse-gram.y (rules_or_grammar_declaration): Require a |
| 1201 | semicolon after a grammar declaration, in the interest of possible |
| 1202 | future changes to the Bison input language. |
| 1203 | Do not allow a stray semicolon at the start of the grammar. |
| 1204 | (rhses.1): Allow one or more semicolons after any rule, including |
| 1205 | just before "|" as required by POSIX. |
| 1206 | * tests/input.at (Torturing the Scanner): Add tests for ";|" in a |
| 1207 | grammar. |
| 1208 | |
| 1209 | 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org> |
| 1210 | |
| 1211 | %parse-param support for lalr1.cc. |
| 1212 | |
| 1213 | * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons, |
| 1214 | b4_cc_constructor_calls, b4_cc_constructor_call, |
| 1215 | b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4 |
| 1216 | definitions. |
| 1217 | (yy::b4_parser_class_name::b4_parser_class_name): Take extra |
| 1218 | parse-param arguments. |
| 1219 | (yy::b4_parser_class_name): Declare instance variables to |
| 1220 | hold parse-param arguments. |
| 1221 | * tests/calc.at: s/value/semantic_value/ because value clashes |
| 1222 | with a member of yy::b4_parser_class_name. Adjust C++ code |
| 1223 | to handle %parse-param. Enable %parse-param test in C++. |
| 1224 | |
| 1225 | 2003-05-12 Paul Eggert <eggert@twinsun.com> |
| 1226 | |
| 1227 | * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the |
| 1228 | English a bit. Fix fclose typo. Change "const char" to "char |
| 1229 | const", and use ANSI C rather than K&R for "main". Suggest |
| 1230 | YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends) |
| 1231 | and suggest yy_switch_to_buffer. |
| 1232 | |
| 1233 | 2003-05-05 Paul Eggert <eggert@twinsun.com> |
| 1234 | |
| 1235 | * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes |
| 1236 | C89. This avoids a diagnostic on compilers that define __STDC__ |
| 1237 | to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in |
| 1238 | <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>. |
| 1239 | |
| 1240 | 2003-05-03 Paul Eggert <eggert@twinsun.com> |
| 1241 | |
| 1242 | * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE): |
| 1243 | Do not overrun array bounds. |
| 1244 | This should fix a bug reported today by Olatunji Oluwabukunmi in |
| 1245 | <http://mail.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>. |
| 1246 | |
| 1247 | 2003-04-29 Akim Demaille <akim@epita.fr> |
| 1248 | |
| 1249 | * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to... |
| 1250 | * src/getargs.c, src/getargs.h: here, as bool, not int. |
| 1251 | (nondeterministic_parser): New. |
| 1252 | * src/parse-gram.y, src/scan-gram.l: Support |
| 1253 | %nondeterministic-parser. |
| 1254 | * src/output.c (prepare): Use nondeterministic_parser instead |
| 1255 | of glr_parser where appropriate. |
| 1256 | * src/tables.c (conflict_row, action_row, save_row) |
| 1257 | (token_actions, token_actions, pack_vector): Ditto. |
| 1258 | |
| 1259 | 2003-04-29 Akim Demaille <akim@epita.fr> |
| 1260 | |
| 1261 | * doc/bison.texinfo (C++ Parsers, Implementing Loops): New. |
| 1262 | |
| 1263 | 2003-04-29 Akim Demaille <akim@epita.fr> |
| 1264 | |
| 1265 | * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet) |
| 1266 | with %pure-parser and %locations to exercise the patch from Yakov |
| 1267 | Markovitch below. |
| 1268 | |
| 1269 | 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be> |
| 1270 | |
| 1271 | * data/yacc.c: (b4_lex_param): Corrected for the case where |
| 1272 | %lex-param is provided and %pure-parser isn't. |
| 1273 | |
| 1274 | 2003-04-27 Paul Eggert <eggert@twinsun.com> |
| 1275 | |
| 1276 | Avoid gcc -Wundef warnings reported by Gerald Pfeifer in |
| 1277 | <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>. |
| 1278 | * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA |
| 1279 | if it is not defined. |
| 1280 | (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined. |
| 1281 | |
| 1282 | 2003-04-26 Paul Eggert <eggert@twinsun.com> |
| 1283 | |
| 1284 | * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_): |
| 1285 | Declare to be of type suitable for the ninf value itself, not of |
| 1286 | type suitable for the corresponding table, since the latter might |
| 1287 | be unsigned but the ninf value might be negative. This fixes a |
| 1288 | bug reported by Alexandre Duret-Lutz in |
| 1289 | <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>. |
| 1290 | |
| 1291 | * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR |
| 1292 | invokes it. We shouldn't invoke it twice because it will attempt |
| 1293 | to put error.o in the archive twice. This fixes a glitch reported |
| 1294 | by Martin Mokrejs in |
| 1295 | <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>. |
| 1296 | |
| 1297 | 2003-04-21 Paul Eggert <eggert@twinsun.com> |
| 1298 | |
| 1299 | * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch |
| 1300 | to gnulib. |
| 1301 | |
| 1302 | 2003-04-21 Yakov Markovitch <Markovitch@iso.ru> |
| 1303 | |
| 1304 | * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]: |
| 1305 | Fix obvious typo that results in uncompilable GLR parsers |
| 1306 | when both %pure-parser and %locations are used. (trivial change) |
| 1307 | |
| 1308 | 2003-04-17 Paul Eggert <eggert@twinsun.com> |
| 1309 | |
| 1310 | * src/scan-gram.l: Add %option nounput, since we no longer use unput. |
| 1311 | (unexpected_eof): Renamed from unexpected_end_of_file, for brevity. |
| 1312 | Do not insert the expected token via unput, as this runs afoul |
| 1313 | of a POSIX-compatibility bug in flex 2.5.31. |
| 1314 | All uses changed to BEGIN the parent state, |
| 1315 | since we no longer insert the expected token via unput. |
| 1316 | * tests/regression.at (Invalid inputs): Remove cascaded diagnostic |
| 1317 | that is no longer emitted after the above change. |
| 1318 | |
| 1319 | * src/conflicts.c (set_conflicts): Resolve all conflicts, not just |
| 1320 | the first one. This change is from Paul Hilfinger, and it fixes |
| 1321 | regression reported by Werner Lemberg in |
| 1322 | <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>. |
| 1323 | |
| 1324 | (resolve_sr_conflict): Don't invoke state_errs_set |
| 1325 | unless one or more tokens have been explicitly made errors. |
| 1326 | Otherwise, the above change causes Bison to abort. |
| 1327 | |
| 1328 | * tests/existing.at (GNU pic Grammar): New test case, taken from |
| 1329 | Lemberg's email. |
| 1330 | |
| 1331 | 2003-03-31 Akim Demaille <akim@epita.fr> |
| 1332 | |
| 1333 | * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file. |
| 1334 | |
| 1335 | 2003-03-31 Akim Demaille <akim@epita.fr> |
| 1336 | |
| 1337 | * src/output.c (prepare_symbols): Avoid trailing spaces in the |
| 1338 | output. |
| 1339 | |
| 1340 | 2003-03-31 Akim Demaille <akim@epita.fr> |
| 1341 | |
| 1342 | * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/. |
| 1343 | From Paul Hilfinger. |
| 1344 | |
| 1345 | 2003-03-29 Akim Demaille <akim@epita.fr> |
| 1346 | |
| 1347 | * m4/error.m4: Do not put under dynamic conditions some code which |
| 1348 | expansion is under static control. |
| 1349 | |
| 1350 | 2003-03-29 Akim Demaille <akim@epita.fr> |
| 1351 | |
| 1352 | * doc/bison.texinfo (How Can I Reset @code{yyparse}): New. |
| 1353 | |
| 1354 | 2003-03-29 Akim Demaille <akim@epita.fr> |
| 1355 | |
| 1356 | * doc/bison.texinfo (Strings are Destroyed): New. |
| 1357 | |
| 1358 | 2003-03-13 Paul Eggert <eggert@twinsun.com> |
| 1359 | |
| 1360 | * .cvsignore: Add configure.lineno. |
| 1361 | * src/.cvsignore: Add yacc. |
| 1362 | * tests/.cvsignore: Add testsuite.log. |
| 1363 | * doc/fdl.texi: Sync with latest FSF version. |
| 1364 | |
| 1365 | 2003-03-12 Paul Eggert <eggert@twinsun.com> |
| 1366 | |
| 1367 | * scan-gram.l (YY_USER_INIT): Initialize code_start, too. |
| 1368 | (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner |
| 1369 | cursor, instead of leaving it undefined. This fixes a bug |
| 1370 | reported by Tim Van Holder in |
| 1371 | <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>. |
| 1372 | * tests/input.at (Torturing the Scanner): Test the scanner on |
| 1373 | an empty input file, which was Tim Van Holder's test case. |
| 1374 | |
| 1375 | * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether |
| 1376 | <sys/resource.h> can be included, include sys/time.h and |
| 1377 | sys/times.h first, if available. This works around the SunOS |
| 1378 | 4.1.4 porting bug reported by Bruce Becker in |
| 1379 | <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>. |
| 1380 | |
| 1381 | * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't |
| 1382 | AC_CHECK_HEADERS([sys/wait.h]), as this interferes with |
| 1383 | AC_HEADER_SYS_WAIT. |
| 1384 | |
| 1385 | Merge changes from gnulib. This was prompted because the CVS |
| 1386 | snapshot didn't build on Solaris 7 due to strnlen problems. |
| 1387 | |
| 1388 | These changes need to be merged back into gnulib: |
| 1389 | * lib/hash.c: Include <stdbool.h> unconditionally. |
| 1390 | * m4/onceonly.m4 (m4_quote): New macro. |
| 1391 | (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE): |
| 1392 | Quote AC_FOREACH variable-expansions properly. |
| 1393 | The 2003-01-03 obstack.h change also needs merging. |
| 1394 | {end of changes requiring merging} |
| 1395 | |
| 1396 | * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4, |

| 1400 | m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4: |
| 1401 | New files, imported from gnulib. |
| 1402 | * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned |
| 1403 | above. |
| 1404 | |
| 1405 | * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4, |
| 1406 | m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current |
| 1407 | gnulib sources. |
| 1408 | |
| 1409 | * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC): |
| 1410 | Add. |
| 1411 | (gl_ERROR): New, replacing jm_PREREQ_ERROR. |
| 1412 | (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA. |
| 1413 | (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy). |
| 1414 | (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN. |
| 1415 | (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH. |
| 1416 | (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK. |
| 1417 | (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG. |
| 1418 | (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New. |
| 1419 | (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC. |
| 1420 | (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC. |
| 1421 | (jm_PREREQ_ARGMATCH): Remove. |
| 1422 | (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul. |
| 1423 | * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h. |
| 1424 | |
| 1425 | * src/system.h: Include <stdbool.h> unconditionally. |
| 1426 | |
| 1427 | * lib/bbitset.h: Include <limits.h> unconditionally. We have been |
| 1428 | assuming at least C89 in the bitset code for some time now. |
| 1429 | |
| 1430 | 2003-03-03 Akim Demaille <akim@epita.fr> |
| 1431 | |
| 1432 | * ro.po: New. |
| 1433 | |
| 1434 | 2003-03-02 Akim Demaille <akim@epita.fr> |
| 1435 | |
| 1436 | * doc/bison.texinfo (Table of Symbols): Reactivate the |
| 1437 | documentation for %lex-param, and %parse-param. |
| 1438 | |
| 1439 | 2003-03-02 Akim Demaille <akim@epita.fr> |
| 1440 | |
| 1441 | * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to |
| 1442 | generate verbose error messages. |
| 1443 | Use the number of tokens as an upper bound in yytname, as it |
| 1444 | cannot be a non terminal. |
| 1445 | |
| 1446 | 2003-03-02 Akim Demaille <akim@epita.fr> |
| 1447 | |
| 1448 | * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error |
| 1449 | message. |
| 1450 | |
| 1451 | 2003-03-02 Akim Demaille <akim@epita.fr> |
| 1452 | |
| 1453 | * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New. |
| 1454 | Use them to exercise yycheck overrun. |
| 1455 | Based on Andrew Suffield's grammar. |
| 1456 | |
| 1457 | 2003-03-02 Akim Demaille <akim@epita.fr> |
| 1458 | |
| 1459 | Create tests/local.at for Bison generic testing macros. |
| 1460 | |
| 1461 | * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to... |
| 1462 | * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS): |
| 1463 | This new file. |
| 1464 | * tests/calc.at (AT_CHECK_CALC): Adjust. |
| 1465 | * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR) |
| 1466 | (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to... |
| 1467 | * tests/local.at: here. |
| 1468 | (AT_COMPILE_CXX): Tags the tests using it as c++. |
| 1469 | Ignore the test if CXX is not functional. |
| 1470 | |
| 1471 | 2003-03-01 Paul Eggert <eggert@twinsun.com> |
| 1472 | |
| 1473 | * src/scan-gram.l (code_start): Initialize it to scanner_cursor, |
| 1474 | not loc->end, since loc->end might contain garbage and this leads |
| 1475 | to undefined behavior on some platforms. |
| 1476 | (id_loc, token_start): Use (IF_LINTed) initial values that do not |
| 1477 | depend on *loc, so that the reader doesn't give the the false |
| 1478 | impression that *loc is initialized. |
| 1479 | (<INITIAL>"%%"): Do not bother setting code_start, since its value |
| 1480 | does not survive the return. |
| 1481 | |
| 1482 | 2003-03-01 Akim Demaille <akim@epita.fr> |
| 1483 | |
| 1484 | * src/scan-gram.l (code_start): Always initialize it when entering |
| 1485 | into yylex, as SC_EPILOGUE is activated *before* the corresponding |
| 1486 | yylex invocation. An alternative would be making it static, but |
| 1487 | then it starts with the second %%'s beginning, instead of its end. |
| 1488 | |
| 1489 | 2003-02-28 Paul Eggert <eggert@twinsun.com> |
| 1490 | |
| 1491 | * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work |
| 1492 | around a UnixWare 7.1.1 porting bug reported by John Hughes in |
| 1493 | <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>. |
| 1494 | |
| 1495 | 2003-02-26 Paul Eggert <eggert@twinsun.com> |
| 1496 | |
| 1497 | * README: Mention compiler bug in Sun Forte Developer 6 update 2. |
| 1498 | Remove Sequent/Pyramid discussion (nobody uses them any more). |
| 1499 | Merge VMS and MS-DOS discussion; these ports may well be dead |
| 1500 | but let's keep mentioning them for now. Put <> around email |
| 1501 | addresses. Add copyright notice. |
| 1502 | |
| 1503 | 2003-02-24 Paul Eggert <eggert@twinsun.com> |
| 1504 | |
| 1505 | * data/glr.c (yy_reduce_print): yylineno -> yylno, |
| 1506 | to avoid collision with flex use of yylineno. |
| 1507 | Problem reported by Bruce Lilly in |
| 1508 | <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>. |
| 1509 | * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise. |

| 1515 | |
| 1516 | * data/lalr1.cc: Use temporary variables instead of casts to |
| 1517 | change integer types. |
| 1518 | Suggested by Paul Eggert. |
| 1519 | |
| 1520 | 2003-02-21 Akim Demaille <akim@epita.fr> |
| 1521 | |
| 1522 | * doc/bison.texinfo: Use "location" consistently to refer to @n, |
| 1523 | to avoid confusions with lalr1.cc's notion of Position. |
| 1524 | Suggested by Paul Eggert. |
| 1525 | |
| 1526 | 2003-02-20 Akim Demaille <akim@epita.fr> |
| 1527 | |
| 1528 | * data/lalr1.cc (position.hh): Make sure "columns" never pushes |
| 1529 | before initial_columns. |
| 1530 | (location.hh): Use consistent variable names when defining the |
| 1531 | operator<<. |
| 1532 | Use "last" so that we subtract from Positions, not from unsigned. |
| 1533 | |
| 1534 | 2003-02-20 Akim Demaille <akim@epita.fr> |
| 1535 | |
| 1536 | * data/lalr1.cc (position.hh): New subfile, including the extended |
| 1537 | and Doxygen'ed documentation of class Position. |

| 1545 | AT_YACC_IF. |
| 1546 | Redefine AT_YYERROR_SEES_LOC_IF using it. |
| 1547 | (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is |
| 1548 | not defined. |
| 1549 | Don't use the location in yy::Parser::error_ and |
| 1550 | yy::Parser::print_ when not %locations. |
| 1551 | Activate more lalr1.cc tests. |
| 1552 | |
| 1553 | 2003-02-19 Akim Demaille <akim@epita.fr> |
| 1554 | |
| 1555 | * data/lalr1.cc: When displaying a line number, be sure to make it |
| 1556 | an int. |

| 1559 | |
| 1560 | * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_): |
| 1561 | Remove, useless. |
| 1562 | (YYABORT, YYACCEPT, YYERROR): New. |
| 1563 | * tests/calc.at: Renable the lalr1.cc test. |
| 1564 | |
| 1565 | 2003-02-19 Akim Demaille <akim@epita.fr> |
| 1566 | |
| 1567 | * tests/calc.at (AT_CHECK_CALC): Check different scenarios of |
| 1568 | error recovery, mixing with/without pops and discarding of the |
| 1569 | lookahead. |
| 1570 | Exercise YYERROR. |
| 1571 | Disable the lalr1.cc tests as currently it doesn't support YYERROR. |
| 1572 | |
| 1573 | 2003-02-17 Paul Eggert <eggert@twinsun.com> |
| 1574 | |
| 1575 | * tests/atlocal.in (LDFLAGS, LIBS): New vars. |
| 1576 | * tests/testsuite.at (AT_COMPILE): Use them. |
| 1577 | This fixes the testsuite problem reported by Robert Lentz in |
| 1578 | <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>. |
| 1579 | |
| 1580 | 2003-02-12 Paul Eggert <eggert@twinsun.com> |
| 1581 | |
| 1582 | * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]: |
| 1583 | Avoid subscript error in yycheck. Bug reported by Andrew Suffield in |
| 1584 | <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>. |
| 1585 | * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise. |
| 1586 | Check for malloc failure, for consistency with yacc.c. |
| 1587 | (yytname_size): Remove, for consistency with yacc.c. |
| 1588 | |
| 1589 | The bug still remains in data/lalr1.cc, as I didn't have time |
| 1590 | to fix it there. |
| 1591 | |
| 1592 | 2003-02-06 Akim Demaille <akim@epita.fr> |
| 1593 | |
| 1594 | * configure.ac (GXX): Rename as... |
| 1595 | (CXX): this, to keep the original Autoconf semantics. |
| 1596 | Require 2.57. |
| 1597 | * data/lalr1.cc: Fix b4_copyright invocations. |
| 1598 | If YYDEBUG is not defined, don't depend upon name_ being defined. |

| 1600 | (Position::filename): New member. |
| 1601 | (Position::Position ()): New. |

| 1603 | (operator- (Position, int)): New. |
| 1604 | (Location::first, Location::last): Rename as... |
| 1605 | (Location::begin, Location::end): these, to mock the conventional |
| 1606 | iterator names. |
| 1607 | (operator<< (Location)): New. |
| 1608 | * tests/atlocal.in (CXX): New. |
| 1609 | * tests/testsuite.at (AT_COMPILE_CXX): New. |
| 1610 | * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the |
| 1611 | locations in a more synthetic way. |
| 1612 | (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if |
| 1613 | lalr1.cc is used. |
| 1614 | Adjust the C locations to match those from Emacs: first column is |
| 1615 | column 0. |
| 1616 | Change all the expected results. |
| 1617 | Conform to the GCS: simplify the locations when applicable. |
| 1618 | (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS) |
| 1619 | (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace |
| 1620 | these CPP macros with the m4 macros new defined by... |
| 1621 | (AT_CHECK_PUSHDEFS): this, i.e.: |
| 1622 | (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS) |
| 1623 | (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS) |
| 1624 | New macros. |
| 1625 | (AT_CHECK_POPDEFS): Undefine them. |
| 1626 | (AT_CHECK_CALC_LALR1_CC): New. |

| 1628 | |
| 1629 | 2003-02-04 Akim Demaille <akim@epita.fr> |
| 1630 | |
| 1631 | * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on |
| 1632 | Location as is defined. |
| 1633 | |
| 1634 | 2003-02-04 Akim Demaille <akim@epita.fr> |
| 1635 | |
| 1636 | * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon |
| 1637 | name_ being defined. |
| 1638 | |
| 1639 | 2003-02-03 Paul Eggert <eggert@twinsun.com> |
| 1640 | |
| 1641 | * src/gram.h (start_symbol): Remove unused decl. |
| 1642 | |
| 1643 | Use more-consistent naming conventions for local vars. |
| 1644 | |
| 1645 | * src/derives.c (derives_compute): Change type of local var from |
| 1646 | int to rule_number. |
| 1647 | * src/gram.c (grammar_rules_partial_print): Likewise. |
| 1648 | * src/print.c (print_core): Likewise. |

| 1652 | local var from r to rp. |
| 1653 | * src/nullable.c (nullable_compute): Likewise. |
| 1654 | |
| 1655 | * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var. |
| 1656 | |
| 1657 | * src/gram.h (symbol_number_as_item_number): Use sym, not s, |
| 1658 | for symbol or symbol_number var. |
| 1659 | * src/reader.c (grammar_start_symbol_set): Likewise. |
| 1660 | * src/reader.h (grammar_start_symbol_set, grammar_symbol_append): |
| 1661 | Likewise. |
| 1662 | * src/state.c (transitions_to): Likewise. |

| 1667 | char * var. |
| 1668 | |
| 1669 | * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE |
| 1670 | var. |
| 1671 | |
| 1672 | * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size |
| 1673 | var. |
| 1674 | |
| 1675 | * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr): |
| 1676 | Use str, not s, for char * var. Use ch, not c, for character var. |
| 1677 | Use size for size var. |
| 1678 | |
| 1679 | * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for |
| 1680 | char * var. |
| 1681 | (uniqstr_print, uniqst_print_processor): Use ustr, not s, for |
| 1682 | uniqstr var. |
| 1683 | * src/uniqstr.h: Likewise. |
| 1684 | |
| 1685 | * src/vcg.c (get_color_str, get_textmode_str, get_shape_str, |
| 1686 | get_layoutalgorithm_str, get_decision_str, get_orientation_str, |
| 1687 | get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str, |
| 1688 | get_view_str, get_linestyle_str, get_arrowstyle_str): Rename |
| 1689 | param to have same name as that of enum, so that we don't use |
| 1690 | "s" to stand for a non-state. |
| 1691 | |
| 1692 | 2003-02-02 Akim Demaille <akim@epita.fr> |
| 1693 | |
| 1694 | * src/scan-skel.l: Scan more than one inert character per yylex |
| 1695 | invocation. |
| 1696 | |
| 1697 | 2003-02-01 Paul Eggert <eggert@twinsun.com> |
| 1698 | |
| 1699 | Version 1.875a. |
| 1700 | |
| 1701 | * po/LINGUAS: Add ms. |
| 1702 | |
| 1703 | 2003-01-30 Akim Demaille <akim@epita.fr> |
| 1704 | |
| 1705 | * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck. |
| 1706 | |
| 1707 | 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU> |
| 1708 | |
| 1709 | * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead |
| 1710 | of $1. |
| 1711 | |
| 1712 | Changes in response to error report by S. Eken: GLR mode does not |
| 1713 | handle negative $ indices or $ indices in embedded rules correctly. |
| 1714 | See <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>. |
| 1715 | |
| 1716 | * data/glr.c (b4_rhs_value): Change to use YYFILL macro. |
| 1717 | (b4_rhs_location): Ditto. |
| 1718 | (yyfill): New function to copy from stack tree into array |
| 1719 | incrementally. |
| 1720 | (yyuserAction): Modify to allow incremental move of semantic values |
| 1721 | to rhs array when in GLR mode. |
| 1722 | Define YYFILL to use in user-defined actions to fill semantic array |
| 1723 | as needed. |
| 1724 | Remove dummy use of yystack, as there is now a guaranteed use. |
| 1725 | (yydoAction): Modify to allow incremental move of semantic values |
| 1726 | to rhs array when in GLR mode. |
| 1727 | (yyresolveAction): Ditto. |
| 1728 | (yyglrShiftDefer): Update comment. |
| 1729 | (yyresolveStates): Use X == NULL for pointers, not !X. |
| 1730 | (yyglrReduce): Ditto. |
| 1731 | (yydoAction): Ditto |
| 1732 | |
| 1733 | * tests/glr-regr1.at: Rename to ... |
| 1734 | * tests/glr-regression.at: Add new regression test for the problems |
| 1735 | described above (adapted from S. Eken). |
| 1736 | Update copyright notice. |
| 1737 | * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at. |
| 1738 | * tests/Makefile.am: Ditto. |
| 1739 | |
| 1740 | 2003-01-28 Paul Eggert <eggert@twinsun.com> |
| 1741 | |
| 1742 | * data/lalr1.cc: Do not use @output_header_name@ unless |
| 1743 | b4_defines_flag is set. This fixes two bugs reported by |
| 1744 | Tim Van Holder in |
| 1745 | <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00071.html> |
| 1746 | and <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>. |
| 1747 | |
| 1748 | 2003-01-21 Paul Eggert <eggert@twinsun.com> |
| 1749 | |
| 1750 | * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that |
| 1751 | we don't need to worry about yyerrlab1 being reported as an |
| 1752 | "unused label" by non-GCC C compilers. The downside is that if |
| 1753 | locations are used then a couple of statements are duplicated each |
| 1754 | time YYERROR is invoked, but the upside is that the warnings |
| 1755 | should vanish. |
| 1756 | (yyerrlab1): Move code to YERROR. |
| 1757 | (yyerrlab2): Remove. Change uses back to yyerrlab1. |
| 1758 | This reverts some of the 2002-12-27 change. |
| 1759 | |
| 1760 | 2003-01-17 Paul Eggert <eggert@twinsun.com> |
| 1761 | |
| 1762 | * src/output.c (symbol_printers_output): Fix typo that led |
| 1763 | to core dump. Problem reported by Antonio Rus in |
| 1764 | <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>. |

| 1767 | Quoc Peyrot <chojin@lrde.epita.fr>, |
| 1768 | Robert Anisko <anisko_r@lrde.epita.fr> |
| 1769 | |
| 1770 | * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop |
| 1771 | when the stacks contain one element, as the loop would otherwise |
| 1772 | free the last state, and then use the top state (the one we just |
| 1773 | popped). This means that the initial elements will not be freed |
| 1774 | explicitly, as is the case in yacc.c; it is not a problem, as |
| 1775 | these elements have fake values. |
| 1776 | |
| 1777 | 2003-01-11 Paul Eggert <eggert@twinsun.com> |
| 1778 | |
| 1779 | * NEWS: %expect-violations are now just warnings, reverting |
| 1780 | to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2 |
| 1781 | bootstrapping problem reported by Matthias Klose; see |
| 1782 | <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>. |
| 1783 | * src/conflicts.c (conflicts_print): Likewise. |
| 1784 | * tests/conflicts.at (%expect not enough, %expect too much, |
| 1785 | %expect with reduce conflicts): Likewise. |
| 1786 | * doc/bison.texinfo (Expect Decl): Document this. Also mention |
| 1787 | that the warning is enabled if the number of conflicts changes |
| 1788 | (not necessarily increases). |
| 1789 | |
| 1790 | * src/getargs.c (version): Update copyright year. |
| 1791 | |
| 1792 | 2003-01-09 Akim Demaille <akim@epita.fr> |
| 1793 | |
| 1794 | * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@. |
| 1795 | |
| 1796 | 2003-01-08 Paul Eggert <eggert@twinsun.com> |
| 1797 | |
| 1798 | * Makefile.maint (WGETFLAGS): |
| 1799 | New macro, containing "-C off" to disable proxy caches. |
| 1800 | All uses of $(WGET) changed to $(WGET) $(WGETFLAGS). |
| 1801 | (rel-check): Use $(WGET) instead of wget. |
| 1802 | |
| 1803 | 2003-01-06 Paul Eggert <eggert@twinsun.com> |
| 1804 | |
| 1805 | * doc/bison.texinfo (Generalized LR Parsing): Add a reference to |
| 1806 | the GLR paper of Scott, Johnstone and Hussain. |
| 1807 | |
| 1808 | 2003-01-04 Paul Eggert <eggert@twinsun.com> |
| 1809 | |
| 1810 | * configure.ac (AC_ARG_ENABLE): Add --disable-yacc. |
| 1811 | (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST. |
| 1812 | * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@. |
| 1813 | (EXTRA_LIBRARIES): New var, for liby.a. |
| 1814 | * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@. |
| 1815 | (EXTRA_SCRIPTS): New var, for yacc. |
| 1816 | |
| 1817 | * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined, |
| 1818 | since GNU C++ (as of 3.2.1) does not allow attributes on labels. |
| 1819 | Problem reported by Nelson H. F. Beebe. |
| 1820 | |
| 1821 | 2003-01-03 Paul Eggert <eggert@twinsun.com> |
| 1822 | |
| 1823 | * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to |
| 1824 | (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5 |
| 1825 | when compiling Bison 1.875's `bitset bset = obstack_alloc |
| 1826 | (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe. |
| 1827 | |
| 1828 | * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition. |
| 1829 | ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not |
| 1830 | grow to a huge size with typical invocation. |
| 1831 | |
| 1832 | * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined): |
| 1833 | Use the pattern recommended by Autoconf 2.57, except also protect |
| 1834 | against double-definition. |
| 1835 | * src/system.h: Likewise. |
| 1836 | Portability issues reported by Nelson H. F. Beebe. |
| 1837 | |
| 1838 | * data/glr.c (yybool): Renamed from bool, to avoid collisions in C. |
| 1839 | All uses changed. Provide a definition in both C and C++. |
| 1840 | (yytrue, yyfalse): Define even if defined (__cplusplus). |
| 1841 | |
| 1842 | * lib/bitset_stats.c (bitset_stats_list): Remove unused var. |
| 1843 | Reported by Nelson H. F. Beebe. |
| 1844 | |
| 1845 | * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno. |
| 1846 | |
| 1847 | 2003-01-02 Paul Eggert <eggert@twinsun.com> |
| 1848 | |
| 1849 | * data/yacc.c (yyerrlab1): Append `;' after attribute, to |
| 1850 | pacify the buggy "smart preprocessor" in MacOS 10.2.3. |
| 1851 | Bug reported by Nelson H. F. Beebe. |
| 1852 | |
| 1853 | 2003-01-01 Paul Eggert <eggert@twinsun.com> |
| 1854 | |
| 1855 | * Version 1.875. |
| 1856 | |
| 1857 | 2002-12-30 Paul Eggert <eggert@twinsun.com> |
| 1858 | |
| 1859 | * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","): |
| 1860 | Moved here from... |
| 1861 | (<INITIAL>","): Here. This causes stray "," to be treated |
| 1862 | more uniformly. |
| 1863 | |
| 1864 | * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the |
| 1865 | last brace in braced code when not in Yacc mode, for compatibility |
| 1866 | with Bison 1.35. This resurrects the 2001-12-15 patch to |
| 1867 | src/reader.c. |
| 1868 | |
| 1869 | * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias |
| 1870 | yystype. This follows up the 2002-12-24 YYSTYPE bug fix. |
| 1871 | |
| 1872 | 2002-12-28 Paul Eggert <eggert@twinsun.com> |
| 1873 | |
| 1874 | * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be |
| 1875 | that of SYM's type. This fixes Debian bug 168069, reported by |
| 1876 | Thomas Olsson. |
| 1877 | |
| 1878 | 2002-12-28 Paul Eggert <eggert@twinsun.com> |
| 1879 | |
| 1880 | Version 1.75f. |
| 1881 | |
| 1882 | Switch back to the Yacc style of conflict reports, undoing some |
| 1883 | of the 2002-07-30 change. |
| 1884 | * doc/bison.texinfo (Understanding): Use Yacc style for |
| 1885 | conflict reports. Also, use new way of locating rules. |
| 1886 | * src/conflicts.c (conflict_report): |
| 1887 | Renamed from conflict_report_yacc, removing the old |
| 1888 | 'conflict_report'. Translate the entire conflict report at once, |
| 1889 | so that we don't assume that "," has the same interpretation in |
| 1890 | all languages. |
| 1891 | (conflicts_output): Use Yacc-style conflict report for each state, |
| 1892 | instead of our more-complicated style. |
| 1893 | (conflicts_print): Use Yacc-style conflict report, except print |
| 1894 | the input file name when not emulating Yacc. |
| 1895 | * tests/conflicts.at (Unresolved SR Conflicts, Defaulted |
| 1896 | Conflicted Reduction, %expect not enough, %expect too much, |
| 1897 | %expect with reduce conflicts): Switch to Yacc-style conflict reports. |
| 1898 | * tests/existing.at (GNU Cim Grammar): Likewise. |
| 1899 | * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise. |
| 1900 | |
| 1901 | * src/complain.c (warn_at, warn, complain_at, complain, fatal_at, |
| 1902 | fatal): Don't invoke fflush; it's not needed and it might even be |
| 1903 | harmful for stdout, as stdout might not be open. |
| 1904 | * src/reduce.c (reduce_print): Likewise. |
| 1905 | |
| 1906 | 2002-12-27 Paul Eggert <eggert@twinsun.com> |
| 1907 | |
| 1908 | Fix a bug where error locations were not being recorded correctly. |
| 1909 | This problem was originally reported by Paul Hilfinger in |
| 1910 | <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>. |
| 1911 | |
| 1912 | * data/yacc.c (yyparse): New local var yylerrsp, to record the |
| 1913 | top of the location stack's error locations. |
| 1914 | (yyerrlab): Set it. When discarding a token, push its location |
| 1915 | onto yylerrsp so that we don't lose track of the error's end. |
| 1916 | (yyerrlab1): Now is only the target of YYERROR, so that we can |
| 1917 | properly record the location of the action that failed. For GCC |
| 1918 | 2.93 and later, insert an __attribute__ ((__unused__)) to avoid |
| 1919 | GCC warning about yyerrlab1 being unused if YYERROR is unused. |
| 1920 | (yyerrlab2): New label, which yyerrlab now falls through to. |
| 1921 | Compute the error's location by applying YYLLOC_DEFAULT to |
| 1922 | the locations of all the symbols that went into the error. |
| 1923 | * doc/bison.texinfo (Location Default Action): Mention that |
| 1924 | YYLLOC_DEFAULT is also invoked for syntax errors. |
| 1925 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): |
| 1926 | Error locations include the locations of all the tokens that were |
| 1927 | discarded, not just the last token. |
| 1928 | |
| 1929 | 2002-12-26 Paul Eggert <eggert@twinsun.com> |
| 1930 | |
| 1931 | * src/files.c: Include quote.h. |
| 1932 | (compute_output_file_names): Warn if we detect conflicting |
| 1933 | outputs to the same file. This should catch the misunderstanding |
| 1934 | exemplified by Debian Bug 165349, reported by Bruce Stephens.. |
| 1935 | |
| 1936 | * src/conflicts.c (conflicts_print): If the user specifies |
| 1937 | "%expect N", report an error if there are any reduce/reduce |
| 1938 | conflicts. This is what the manual says should happen. |
| 1939 | This fixes Debian bug 130890, reported by Anthony DeRobertis. |
| 1940 | * tests/conflicts.at (%expect with reduce conflicts): New test. |
| 1941 | |
| 1942 | Don't use m4_include on relative file names, as it doesn't work as |
| 1943 | desired if there happens to be a file with that name under ".". |
| 1944 | |
| 1945 | * m4sugar/version.m4: Remove; it was included but it wasn't used. |
| 1946 | * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4. |
| 1947 | * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4. |
| 1948 | * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4. |
| 1949 | * src/output.c (output_skeleton): Use full path names when |
| 1950 | specifying a file to include; don't rely on include path, as |
| 1951 | it's unreliable when the working file contains a file with |
| 1952 | that name. |
| 1953 | |
| 1954 | 2002-12-25 Paul Eggert <eggert@twinsun.com> |
| 1955 | |
| 1956 | Remove obsolete references to bison.simple and bison.hairy. |
| 1957 | Problem mentioned by Aubin Mahe in |
| 1958 | <http://mail.gnu.org/archive/html/help-bison/2002-12/msg00010.html>. |
| 1959 | * data/glr.c: Comment fix. |
| 1960 | * doc/bison.1: Remove references. Also, mention "yacc". |
| 1961 | |
| 1962 | * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL |
| 1963 | with -g option. |
| 1964 | |
| 1965 | * src/parse-gram.y (declaration): Use enum "report_states" rather |
| 1966 | than its numeric value 1. |
| 1967 | |
| 1968 | * src/scan-skel.l ("@output ".*\n): Close any old yyout before |
| 1969 | opening a new one. This fixes Debian bug 165349, reported by |
| 1970 | Bruce Stephens. |
| 1971 | |
| 1972 | 2002-12-24 Paul Eggert <eggert@twinsun.com> |
| 1973 | |
| 1974 | Version 1.75e. |
| 1975 | |
| 1976 | * Makefile.maint (cvs-update): Don't assume that the shell |
| 1977 | supports $(...), as Solaris sh doesn't. |
| 1978 | |
| 1979 | * src/parse-gram.y (lloc_default): Remove test for empty |
| 1980 | nonterminals at the end, since it didn't change the result. |
| 1981 | |
| 1982 | 2002-12-24 Paul Eggert <eggert@twinsun.com> |
| 1983 | |
| 1984 | If the user does not define YYSTYPE as a macro, Bison now declares it |
| 1985 | using typedef instead of defining it as a macro. POSIX requires this. |
| 1986 | For consistency, YYLTYPE is also declared instead of defined. |
| 1987 | |
| 1988 | %union directives can now have a tag before the `{', e.g., the |
| 1989 | directive `%union foo {...}' now generates the C code |
| 1990 | `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility. |
| 1991 | The default union tag is `YYSTYPE', for compatibility with Solaris 9 |
| 1992 | Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE' |
| 1993 | instead of `yyltype'. |
| 1994 | |
| 1995 | `yystype' and `yyltype' are now obsolescent macros instead of being |
| 1996 | typedefs or tags; they are no longer documented and will be |
| 1997 | withdrawn in a future release. |
| 1998 | |
| 1999 | * data/glr.c (b4_location_type): Remove. |
| 2000 | (YYSTYPE): Renamed from yystype. |
| 2001 | (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef. |
| 2002 | (struct YYLTYPE): Renamed from struct yyltype. |
| 2003 | (YYLTYPE): Renamed from yyltype. |
| 2004 | (yyltype, yystype): New (and obsolescent) macros, |
| 2005 | for backward compatibility. |
| 2006 | * data/yacc.c: Likewise. |
| 2007 | |
| 2008 | * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user |
| 2009 | does not specify a union tag. This is for compatibility with |
| 2010 | Solaris 9 yacc. |
| 2011 | |
| 2012 | * src/parse-gram.y (add_param): 2nd arg is now char * not char |
| 2013 | const *, since it is now modified by stripping surrounding { }. |
| 2014 | (current_braced_code): Remove. |
| 2015 | (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION, |
| 2016 | PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include |
| 2017 | trailing " {...}". Now of type <chars>. |
| 2018 | (grammar_declaration): Adjust to bundled tokens. |
| 2019 | (code_content): Remove; stripping is now done by add_param. |
| 2020 | (print_token_value): Print contents of bundled tokens. |
| 2021 | (token_name): New function. |
| 2022 | |
| 2023 | * src/reader.h (braced_code, current_braced_code): Remove. |
| 2024 | (token_name): New decl. |
| 2025 | |
| 2026 | * src/scan-gram.l (handle_dollar, handle_at): Now takes int |
| 2027 | token_type, not braced_code code_kind. All uses changed. |
| 2028 | (SC_PRE_CODE): New state, for scanning after a keyword that |
| 2029 | has (or usually has) an immediately-following braced code. |
| 2030 | (token_type): New local var, to keep track of which token type |
| 2031 | to return when scanning braced code. |
| 2032 | (<INITIAL>"%destructor", <INITIAL>"%lex-param", |
| 2033 | <INITIAL>"%parse-param", <INITIAL>"%printer", |
| 2034 | <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE |
| 2035 | instead of returning a token type immediately. |
| 2036 | (<INITIAL>"{"): Set token type. |
| 2037 | (<SC_BRACED_CODE>"}"): Use it. |
| 2038 | (handle_action_dollar, handle_action_at): Now returns bool |
| 2039 | indicating success. Fail if ! current_rule; this prevents a core dump. |
| 2040 | (handle_symbol_code_dollar, handle_symbol_code_at): |
| 2041 | Remove; merge body into caller. |
| 2042 | (handle_dollar, handle_at): Complain in invalid contexts. |
| 2043 | |
| 2044 | * NEWS, doc/bison.texinfo: Document the above. |
| 2045 | * NEWS: Fix years and program names in copyright notice. |
| 2046 | |
| 2047 | 2002-12-17 Paul Eggert <eggert@twinsun.com> |
| 2048 | |
| 2049 | * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error |
| 2050 | Reporting, Table of Symbols): Omit mentions of %lex-param and |
| 2051 | %parse-param from the documentation for now. |
| 2052 | |
| 2053 | 2002-12-15 Paul Eggert <eggert@twinsun.com> |
| 2054 | |
| 2055 | Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke |
| 2056 | GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no |
| 2057 | lookahead symbol, and which sets yychar in parser actions) and it |
| 2058 | disagreed with the Bison documentation. Bug |
| 2059 | reported by Andrew Walrond. |
| 2060 | |
| 2061 | * data/yacc.c (YYTRANSLATE): Don't check for negative argument, |
| 2062 | as the caller now does that. |
| 2063 | (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken. |
| 2064 | (YYEMPTY): Parenthesize right hand side, since others use it. |
| 2065 | (yyparse): Don't assume that our generated code is the only code |
| 2066 | that sets yychar. |
| 2067 | |
| 2068 | 2002-12-13 Paul Eggert <eggert@twinsun.com> |
| 2069 | |
| 2070 | Version 1.75d. |
| 2071 | |
| 2072 | POSIX requires a "yacc" command. |
| 2073 | * src/Makefile.am (bin_SCRIPTS): New macro, for yacc. |
| 2074 | (MOSTLYCLEANFILES): Add yacc. |
| 2075 | (yacc): New rule. |
| 2076 | * doc/bison.texinfo (Invocation, Bison Options): Mention yacc |
| 2077 | as an alias for bison y. |
| 2078 | |
| 2079 | * po/LINGUAS: Add da. |
| 2080 | |
| 2081 | * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around |
| 2082 | problem with latest <getopt.h>. |
| 2083 | (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro. |
| 2084 | |
| 2085 | * doc/fdl.texi: Upgrade to 1.2. |
| 2086 | * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h |
| 2087 | lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c, |
| 2088 | lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with |
| 2089 | gnulib. |
| 2090 | * config/install-sh: Sync with autotools. |
| 2091 | |
| 2092 | Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in |
| 2093 | <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>. |
| 2094 | * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless |
| 2095 | locations are requested. |
| 2096 | (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless |
| 2097 | locations are requested. |
| 2098 | |
| 2099 | 2002-12-12 Paul Eggert <eggert@twinsun.com> |
| 2100 | |
| 2101 | Remove unportable casts and storage allocation tricks. |
| 2102 | While we're at it, remove almost all casts, since they |
| 2103 | usually aren't needed and are a sign of trouble. |
| 2104 | |
| 2105 | * configure.ac (AC_CHECK_TYPES): Check for uintptr_t. |
| 2106 | |
| 2107 | * src/derives.c (derives_compute): Do not subtract NTOKENS from |
| 2108 | the pointer DSET returned by malloc; this isn't portable. |
| 2109 | Instead, always use DSET[i - NTOKENS] rather than DSET[i]. |
| 2110 | Similarly for DERIVES. |
| 2111 | * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP. |
| 2112 | * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE. |
| 2113 | * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap |
| 2114 | |
| 2115 | * src/derives.c (derives_compute): Do not bother invoking |
| 2116 | int_of_rule_number, since rule numbers are integers. |
| 2117 | |
| 2118 | * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N) |
| 2119 | rather than XMALLOC (char, N). |
| 2120 | |
| 2121 | * src/files.c (filename_split): Rewrite to avoid cast. |
| 2122 | |
| 2123 | * src/gram.h (symbol_number_as_item_number, |
| 2124 | item_number_as_symbol_number, rule_number_as_item_number, |
| 2125 | item_number_as_rule_number): |
| 2126 | Now inline functions rather than macros, to avoid casts. |
| 2127 | * src/state.h (state_number_as_int): Likewise. |
| 2128 | * src/tables.c (state_number_to_vector_number, |
| 2129 | symbol_number_to_vector_number): Likewise. |
| 2130 | |
| 2131 | * src/gram.h (int_of_rule_number): Remove; no longer used. |
| 2132 | |
| 2133 | * src/lalr.c (add_lookback_edge): Use malloc rather than calloc, |
| 2134 | since the resulting storage is always stored into. |
| 2135 | |
| 2136 | * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place |
| 2137 | where it's needed. |
| 2138 | |
| 2139 | * src/muscle_tab.c (muscle_m4_output): |
| 2140 | Now inline. Return bool, not int. |
| 2141 | * src/state.c (state_compare): Likewise. |
| 2142 | * src/symtab.c (symbol_check_defined, |
| 2143 | symbol_check_alias_consistency, symbol_pack, symbol_translation, |
| 2144 | hash_compare_symbol, hash_symbol): |
| 2145 | Likewise. |
| 2146 | * src/uniqstr.c (uniqstr_print): Likewise. |
| 2147 | * src/muscle_tab.c (muscle_m4_output_processor): |
| 2148 | New function, to avoid casts. |
| 2149 | * src/state.c (state_comparator, stage_hasher): Likewise. |
| 2150 | * src/symtab.c (symbol_check_defined_processor, |
| 2151 | symbol_check_alias_consistency_processor, symbol_pack_processor, |
| 2152 | symbol_translation_processor, hash_symbol_comparator, |
| 2153 | hash_symbol_hasher): Likewise. |
| 2154 | * src/uniqstr.c (uniqstr_print_processor): Likewise. |
| 2155 | * src/muscle_tab.c (muscles_m4_output): |
| 2156 | Use new functions instead of casting old functions unportably. |
| 2157 | * src/state.c (state_hash_new): Likewise. |
| 2158 | * src/symtab.c (symbols_new, symbols_do, symbols_check_defined, |
| 2159 | symbols_token_translations_init): |
| 2160 | Likewise. |
| 2161 | * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise. |
| 2162 | |
| 2163 | * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local |
| 2164 | var instead of casting to long, to avoid casts. |
| 2165 | (prepare_states): Use MALLOC rather than alloca, so that we don't |
| 2166 | have to worry about alloca. |
| 2167 | * src/state.c (state_hash_lookup): Likewise. |
| 2168 | |
| 2169 | * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char |
| 2170 | local var instead of casting to unsigned char, to avoid casts. |
| 2171 | |
| 2172 | * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC, |
| 2173 | STATE_ALLOC): Remove. |
| 2174 | (transitions_new, errs_new, reductions_new, state_new): Use malloc |
| 2175 | rather than calloc, and use offsetof to avoid allocating slightly |
| 2176 | too much storage. |

| 2194 | (CALLOC, MALLOC, REALLOC): New macros. |
| 2195 | All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these |
| 2196 | new macros. |
| 2197 | |
| 2198 | * src/tables.c (table_size): Now int, to pacify GCC. |
| 2199 | (table_grow, table_ninf_remap): Use signed table size. |
| 2200 | (save_row): Don't bother initializing locals when not needed. |
| 2201 | (default_goto, goto_actions, pack_vector): Remove unnecessary casts. |
| 2202 | * src/uniqstr.c (hash_compare_uniqstr): Likewise. |
| 2203 | |

| 2211 | 2002-12-09 Paul Eggert <eggert@twinsun.com> |
| 2212 | |
| 2213 | Change identifier spellings to avoid collisions with names |
| 2214 | that are reserved by POSIX. |
| 2215 | |
| 2216 | Don't use names ending in _t, since POSIX reserves them. |
| 2217 | For consistency, remove _e and _s endings -- they're weren't |
| 2218 | needed to remove ambiguity. All uses changed. |
| 2219 | * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in |
| 2220 | turn was just renamed from struniq_t. |
| 2221 | * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor, |
| 2222 | which in turn was just renamed from struniq_processor_t. |

| 2294 | value_t_as_yystype -> value_as_yystype. |
| 2295 | |
| 2296 | Don't include <errno.h> in the mainstream code, since it |
| 2297 | reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'. |
| 2298 | * lib/get-errno.c, lib/get-errno.h: New files. |
| 2299 | * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h, |
| 2300 | get-errno.c. |
| 2301 | * src/files.c (xfopen, xfclose): Use get_errno instead of errno. |
| 2302 | * src/output.c (output_skeleton): Likewise. |

| 2310 | (OUTPUT_EXT): Renamed from EXT_OUTPUT. |
| 2311 | |
| 2312 | Avoid str[a-z]*, since <string.h> reserves that name space. |
| 2313 | Change all instances of "struniq" in names to "uniqstr", and |
| 2314 | likewise for "STRUNIQ" and "UNIQSTR". |
| 2315 | * src/uniqstr.c: Renamed from src/struniq.c. |
| 2316 | * src/uniqstr.h: Renamed from src/struniq.h. |

| 2328 | (N_EXPAND): Renamed from N_STRETCH. |
| 2329 | |
| 2330 | Avoid *_MAX and *_MIN, since <limits.h> reserves that name space. |
| 2331 | * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX. |
| 2332 | * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX): |
| 2333 | Remove; unused. |

| 2342 | Unnecessary casts removed from above defines. |
| 2343 | |
| 2344 | |

| 2347 | * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from |
| 2348 | G_NODE_ALIGNEMENT. |
| 2349 | |
| 2350 | |
| 2351 | * lib/timevar.c (timevar_report): Renamed from time_report, |
| 2352 | for consistency with other names. |
| 2353 | * lib/timevar.h (timevar_report): New decl. |
| 2354 | * src/system.h (time_report): Remove; decl is now in lib/timevar.h. |
| 2355 | |
| 2356 | |
| 2357 | Sort include-file uses. |
| 2358 | |
| 2359 | Reorder all include files under src to be in the order "system.h". |
| 2360 | then the ../lib include files in angle brackets (alphabetized), |
| 2361 | then the . include files in double-quotes (alphabetized). Fix |
| 2362 | dependency breakages encountered in this process, as follows: |
| 2363 | * src/closure.h, src/derives.h, src/state.h: Include "gram.h". |
| 2364 | * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff. |
| 2365 | * src/state.h: Include "symtab.h". |
| 2366 | |
| 2367 | 2002-12-08 Paul Eggert <eggert@twinsun.com> |
| 2368 | |
| 2369 | * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__, |
| 2370 | since this causes problems when __file__ contains character |
| 2371 | sequences like "@" that are treated specially by src/scan-skel.l. |
| 2372 | Instead, just use the file's basename. This fixes the bug |
| 2373 | reported by Martin Mokrejs in |
| 2374 | <http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>. |
| 2375 | |
| 2376 | 2002-12-06 Paul Eggert <eggert@twinsun.com> |
| 2377 | |
| 2378 | Add support for rules that do not have trailing semicolons, as |
| 2379 | POSIX requires. Improve the quality of locations in Bison |
| 2380 | diagnostics. |
| 2381 | |
| 2382 | * src/location.c: Include <quotearg.h>. |
| 2383 | (empty_location): Now const. |
| 2384 | (location_print): New function. Follow the recommendation of the |
| 2385 | GNU Coding Standards for locations that span file boundaries. |
| 2386 | * src/location.h: Do not include <quotearg.h>; no longer needed. |
| 2387 | (boundary): New type. |
| 2388 | (location_t): Use it. This allows locations to span file boundaries. |
| 2389 | All member uses changed: file -> start.file or end.file (as needed), |
| 2390 | first_line -> start.line, first_column -> start.column, |
| 2391 | last_line -> end.line, last_column -> end.column. |
| 2392 | (equal_boundaries): New function. |
| 2393 | (LOCATION_RESET, LOCATION_STEP): Remove. |
| 2394 | (LOCATION_PRINT): Remove. All callers changed to use location_print. |
| 2395 | (empty_location): Now const. |
| 2396 | (location_print): New decl. |
| 2397 | * src/parse-gram.y (lloc_default): New function, which handles |
| 2398 | empty locations more accurately. |
| 2399 | (YYLLOC_DEFAULT): Use it. |
| 2400 | (%token COLON): Remove. |
| 2401 | (%token ID_COLON): New token. |
| 2402 | (rules): Use it. |
| 2403 | (declarations, rules): Remove trailing semicolon. |
| 2404 | (declaration, rules_or_grammar_declaration): |
| 2405 | Allow empty (";") declaration. |
| 2406 | (symbol_def): Remove empty actions; no longer needed. |
| 2407 | (rules_or_grammar_declaration): Remove trailing semicolon. |
| 2408 | (semi_colon.opt): Remove. |
| 2409 | * src/reader.h: Include location.h. |
| 2410 | (scanner_cursor): New decl. |
| 2411 | * src/reduce.c (nonterminals_reduce): Use warn_at rather than |
| 2412 | rolling our own. |
| 2413 | * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead |
| 2414 | of *loc. |
| 2415 | (STEP): Remove. No longer needed, now that adjust_location does |
| 2416 | the work. All uses removed. |
| 2417 | (scanner_cursor): New var. |
| 2418 | (adjust_location): Renamed from extend_location. It now sets |
| 2419 | *loc and adjusts the scanner cursor. All uses changed. |
| 2420 | Don't bother testing for CR. |
| 2421 | (handle_syncline): Remove location arg; now updates scanner cursor. |
| 2422 | All callers changed. |
| 2423 | (unexpected_end_of_file): Now accepts start boundary of token or |
| 2424 | comment, not location. All callers changed. Update scanner cursor, |
| 2425 | not the location. |
| 2426 | (SC_AFTER_IDENTIFIER): New state. |
| 2427 | (context_state): Renamed from c_context. All uses changed. |
| 2428 | (id_loc, code_start, token_start): New local vars. |
| 2429 | (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all |
| 2430 | processing of Yacc white space and equivalents here. |
| 2431 | (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER |
| 2432 | instead of returning ID immediately, since we need to search for |
| 2433 | a subsequent colon. |
| 2434 | (<INITIAL>"'", "\""): Save token_start. |
| 2435 | (<INITIAL>"%{", "{", "%%"): Save code_start. |
| 2436 | (<SC_AFTER_IDENTIFIER>): New state, looking for a colon. |
| 2437 | (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>): |
| 2438 | BEGIN context_state at end, not INITIAL. |
| 2439 | (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'", |
| 2440 | <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>): |
| 2441 | Return correct token start. |
| 2442 | (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when |
| 2443 | the start of a character, string or multiline comment is found. |
| 2444 | * tests/conflicts.at (S/R in initial, Defaulted Conflicted |
| 2445 | Reduction): Adjust reported locations to match the more-precise |
| 2446 | results now expected. |
| 2447 | * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise. |
| 2448 | * tests/reduce.at (Useless Rules, Reduced Automaton, |
| 2449 | Underivable Rules): Likewise. |
| 2450 | * tests/regression.at (Invalid inputs): No longer `expecting ";" |
| 2451 | or "|"' now that so many other tokens are allowed by the new grammar. |
| 2452 | |
| 2453 | * src/complain.h (current_file): Remove duplicate decl; |
| 2454 | current_file is now owned by files.h. |
| 2455 | * src/complain.c, src/scan-gram.l: Include files.h. |
| 2456 | |
| 2457 | 2002-12-06 Paul Eggert <eggert@twinsun.com> |
| 2458 | |
| 2459 | * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule] |
| 2460 | promotes to int; it might be unsigned int. |
| 2461 | * data/yacc.c (yy_reduce_print): Likewise. |
| 2462 | |
| 2463 | * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should |
| 2464 | be #defined in the prologue, not in the Bison declarations. |
| 2465 | This fixes Debian Bug 102878, reported by Shaul Karl. |
| 2466 | |
| 2467 | 2002-12-02 Paul Eggert <eggert@twinsun.com> |
| 2468 | |
| 2469 | * configure.ac (AC_REPLACE_FUNCS): Add strtoul. |
| 2470 | * lib/strtoul.c: New file, from gnulib. |
| 2471 | This fixes a porting bug reported by Peter Klein in |
| 2472 | <http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>. |
| 2473 | |
| 2474 | 2002-11-30 Paul Eggert <eggert@twinsun.com> |
| 2475 | |
| 2476 | * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue, |
| 2477 | and put only a forward declaration in the prologue. This is for |
| 2478 | consistency with the other scanner helper functions. |
| 2479 | |
| 2480 | Type clashes now generate warnings, not errors, since it |
| 2481 | appears that POSIX may allow some grammars with type clashes. |
| 2482 | * src/reader.c (grammar_current_rule_check): Warn about |
| 2483 | type clashes instead of complaining. |
| 2484 | * tests/input.at (Type Clashes): Expect warnings, not complaints. |
| 2485 | |
| 2486 | Add Yacc library, since POSIX requires it. |
| 2487 | * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu. |
| 2488 | * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros. |
| 2489 | * lib/main.c, lib/yyerror.c: New files. |
| 2490 | |
| 2491 | gram_error can be static; it need not be extern. |
| 2492 | * src/reader.h (gram_error): Remove decl. |
| 2493 | * src/parse-gram.y (gram_error): Now static. Add static decl. |
| 2494 | (print_token_value): Omit parameter names from forward decl, |
| 2495 | for consistency. |
| 2496 | |
| 2497 | 2002-11-29 Paul Eggert <eggert@twinsun.com> |
| 2498 | |
| 2499 | * doc/bison.texinfo: Emphasize that yylex and yyerror must |
| 2500 | be declared before being used. E.g., one should typically |
| 2501 | declare them in the prologue. Use GNU coding style in examples. |
| 2502 | Put "const" consistently after the type it modifies. Mention |
| 2503 | that C99 supports "inline". Mention that yyerror traditionally |
| 2504 | returns "int". |
| 2505 | |
| 2506 | %parse-param and %lex-param now take just one argument, the |
| 2507 | declaration; the argument name is deduced from the declaration. |
| 2508 | |
| 2509 | * doc/bison.texinfo (Parser Function, Pure Calling, Error |
| 2510 | Reporting, Table of Symbols): Document this. |
| 2511 | * src/parse-gram.y (add_param): New function. |
| 2512 | (COMMA): Remove. |
| 2513 | (declaration): Implement new rule for %parse-param and %lex-param. |
| 2514 | * src/scan-gram.l: "," now elicits a warning, rather than being |
| 2515 | a token; this is more compatible with byacc. |
| 2516 | * tests/calc.at (Simple LALR Calculator): Adopt new convention. |
| 2517 | |
| 2518 | 2002-11-27 Paul Eggert <eggert@twinsun.com> |
| 2519 | |
| 2520 | Rename identifiers to avoid real and potential collisions. |
| 2521 | |
| 2522 | * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput, |
| 2523 | to avoid collision with lex macro described by Bruce Lilly in |
| 2524 | <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>. |
| 2525 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise. |
| 2526 | * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value. |
| 2527 | * src/parse-gram.y (print_token_value): Renamed from yyprint. |
| 2528 | All uses changed. |
| 2529 | (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed. |
| 2530 | The name "yycontrol" violates the name space rules, and this stuff |
| 2531 | wasn't being used anyway. |
| 2532 | (input): Remove action; this stuff wasn't being used. |
| 2533 | (gram_error): Rename local variable yylloc -> loc. |
| 2534 | * src/reader.h (struct gram_control_s, gram_control_t): Remove. |
| 2535 | (YY_DECL): Don't use "yy" at start of local variables. |
| 2536 | All uses changed, e.g., yylloc -> loc. |
| 2537 | * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed. |
| 2538 | (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed. |
| 2539 | (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed. |
| 2540 | (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed. |
| 2541 | |
| 2542 | * src/parse-gram.y (gram_error): loc is now const *. |
| 2543 | * src/reader.h (gram_error): Likewise. |
| 2544 | |
| 2545 | 2002-11-24 Paul Eggert <eggert@twinsun.com> |
| 2546 | |
| 2547 | Version 1.75c. |
| 2548 | |
| 2549 | * tests/actions.at (Actions after errors): Use an output format |
| 2550 | more similar to that of the Printers and Destructors test. |
| 2551 | Test the position of the ';' token too. |
| 2552 | (Printers and Destructors): Likewise. |
| 2553 | (Printers and Destructors: %glr-parser): Remove for now, to avoid |
| 2554 | unnecessarily alarming people when the test fails. |
| 2555 | |
| 2556 | * data/yacc.c (yyerrlab1): Move this label down, so that the |
| 2557 | parser does not discard the lookahead token if the user code |
| 2558 | invokes YYERROR. This change is required for POSIX conformance. |
| 2559 | |
| 2560 | * lib/error.c: Sync with gnulib. |
| 2561 | |
| 2562 | 2002-11-22 Paul Eggert <eggert@twinsun.com> |
| 2563 | |
| 2564 | * lib/quotearg.c, lib/quotearg.h: Sync with gnulib. |

| 2571 | |
| 2572 | 2002-11-20 Paul Eggert <eggert@twinsun.com> |
| 2573 | |
| 2574 | Avoid use of <assert.h>, as the GNU Coding Standards hint that one |
| 2575 | should use `if (! x) abort ();' rather than `assert (x);', and |
| 2576 | anyway it's one less thing to worry about configuring. |
| 2577 | |
| 2578 | * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>. |
| 2579 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise, |
| 2580 | and replace all instances of assert with abort. |
| 2581 | * tests/calc.at (_AT_DATA_CALC_Y): Likewise. |
| 2582 | * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise. |
| 2583 | |
| 2584 | * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates, |
| 2585 | yyresolveAction, yyprocessOneStack): Use abort rather than assert. |
| 2586 | * lib/hash.c (hash_lookup, hash_get_first, hash_get_next, |
| 2587 | hash_find_entry, hash_rehash, hash_insert): Likewise. |
| 2588 | * src/conflicts.c (resolve_sr_conflict): Likewise. |

| 2600 | get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str, |
| 2601 | get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise. |
| 2602 | |
| 2603 | * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef. |
| 2604 | (ARGMATCH_CONSTRAINT): New macro. |
| 2605 | (ARGMATCH_ASSERT): Use it. |
| 2606 | |
| 2607 | * src/system.h (verify): New macro. |
| 2608 | * src/getargs.c (trace_argmatch, report_argmatch): Use verify |
| 2609 | rather than assert. |
| 2610 | * src/tables.c (tables_generate): Likewise. |
| 2611 | |
| 2612 | * src/struniq.c (struniq_assert): Now returns void, and aborts |
| 2613 | if the assertion is false. |
| 2614 | (struniq_assert_p): Remove. |
| 2615 | * src/struniq.h: Likewise. |
| 2616 | |
| 2617 | 2002-11-18 Paul Eggert <eggert@twinsun.com> |
| 2618 | |
| 2619 | * data/glr.c (yygetLRActions): Replace `yyindex' with |
| 2620 | `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch. |
| 2621 | This fixes the regression with Sun ONE Studio 7 cc that I reported in |
| 2622 | <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>. |
| 2623 | |
| 2624 | 2002-11-18 Akim Demaille <akim@epita.fr> |
| 2625 | |
| 2626 | * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a |
| 2627 | space. |
| 2628 | From Tim Van Holder. |
| 2629 | |
| 2630 | 2002-11-17 Paul Eggert <eggert@twinsun.com> |
| 2631 | |
| 2632 | Pacify Sun ONE Studio 7 lint. Also, rename "ParseError" |
| 2633 | to "SyntaxError" for consistency with my 2002-11-15 change. |
| 2634 | |
| 2635 | * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do |
| 2636 | not define to {}, since this breaks the common use of `YYDPRINTF |
| 2637 | ((...));' if a single statement is desired (e.g. before `else'). |
| 2638 | Work around GCC warnings by surrounding corresponding calls with |
| 2639 | {} if needed. |
| 2640 | (yyhasResolvedValue): Remove unused function. |
| 2641 | (yymergeOptionSets, yyresolvStack): Use `continue;' for empty |
| 2642 | loop body. |
| 2643 | (yyreportSyntaxError): Renamed from yyreportParseError. |
| 2644 | (yyrecoverSyntaxError): Renamed from yyrecoverParseError. |
| 2645 | All uses changed. |
| 2646 | * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of |
| 2647 | extern when possible. Remove unused initializations. |
| 2648 | |
| 2649 | 2002-11-16 Akim Demaille <akim@epita.fr> |
| 2650 | |
| 2651 | Augment the similarity between GLR and LALR traces. |
| 2652 | |
| 2653 | * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print) |
| 2654 | (YY_REDUCE_PRINT): New. |
| 2655 | (yyparse): Use them. |
| 2656 | * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for |
| 2657 | YYDPRINT here. |
| 2658 | (yyglrReduce, yyrecoverParseError, yyparse): Don't report the |
| 2659 | state reached after the reduction/recovery, since... |
| 2660 | (yyparse, yyprocessOneStack): Report the state we are entering in. |
| 2661 | |
| 2662 | 2002-11-16 Akim Demaille <akim@epita.fr> |
| 2663 | |
| 2664 | * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types): |
| 2665 | Add support for --trace=skeleton. |
| 2666 | * src/scan-skel.l: %option debug. |
| 2667 | Scan strings of non-@ or \n instead of character by character. |
| 2668 | (scan_skel): Handle trace_skeleton. |
| 2669 | (QPUTS): New. |
| 2670 | (@output_parser_name@, @output_header_name@): ``Restore'' their |
| 2671 | support (used to be M4 macros). |
| 2672 | * data/yacc.c: Quote larger chunks, a la glr.c. |
| 2673 | * data/lalr1.cc: Likewise. |
| 2674 | The header guards are no longer available, so use some other |
| 2675 | string than `YYLSP_NEEDED'. |
| 2676 | |
| 2677 | 2002-11-16 Akim Demaille <akim@epita.fr> |
| 2678 | |
| 2679 | Make the ``Printers and Destructors'' test more verbose, taking |
| 2680 | `yacc.c''s behavior as (possibly wrong) reference. |
| 2681 | |
| 2682 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf |
| 2683 | instead of fprint on stdout. |
| 2684 | Set and report the last_line of the symbols. |
| 2685 | Consistently display values and locations. |
| 2686 | |
| 2687 | 2002-11-16 Paul Eggert <eggert@twinsun.com> |
| 2688 | |
| 2689 | * data/yacc.c: Avoid over-quoting of __line__ and __file__. |
| 2690 | |
| 2691 | 2002-11-15 Paul Eggert <eggert@twinsun.com> |
| 2692 | |
| 2693 | * tests/actions.at (Actions after errors): New test case. |
| 2694 | |
| 2695 | * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo, |
| 2696 | src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h, |
| 2697 | tests/action.at, tests/calc.at, tests/conflicts.at, |
| 2698 | tests/cxx-type.at, tests/regression.at: |
| 2699 | "parse error" -> "syntax error" for POSIX compatibility. |
| 2700 | "parsing stack overflow..." -> "parser stack overflow" so |
| 2701 | that code matches Bison documentation. |
| 2702 | |
| 2703 | 2002-11-15 Akim Demaille <akim@epita.fr> |
| 2704 | |
| 2705 | * src/parse-gram.y (declaration): Have %parse-param and %lex-param |
| 2706 | take two BRACED_CODE, not two string_content. |
| 2707 | Free the scanner's obstack when we are done. |
| 2708 | (code_content): New. |
| 2709 | * tests/calc.at: Adjust. |
| 2710 | * doc/bison.texinfo: Adjust. |
| 2711 | Also, make sure to include the `,' for these declarations. |
| 2712 | |
| 2713 | 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be> |
| 2714 | |
| 2715 | * m4/prereq.m4: Removed the commented jm_PREREQ_HASH |
| 2716 | definition; avoids potential autoreconf problems. |
| 2717 | |
| 2718 | 2002-11-15 Akim Demaille <akim@epita.fr> |
| 2719 | |
| 2720 | Always check the value returned by yyparse. |
| 2721 | |
| 2722 | * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value |
| 2723 | returned by yyparse. |
| 2724 | (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument. |
| 2725 | Adjust calls. |
| 2726 | * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value |
| 2727 | returned by yyparse. |
| 2728 | |
| 2729 | 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU> |
| 2730 | |
| 2731 | * data/glr.c (yyFail): Always set yyerrflag. Corrects regression |
| 2732 | on input.at test. |
| 2733 | |
| 2734 | 2002-11-14 Paul Eggert <eggert@twinsun.com> |
| 2735 | |
| 2736 | * src/output.c (output_skeleton): Call xfopen instead of |
| 2737 | duplicating xfopen's body. |
| 2738 | |
| 2739 | Fix bugs reported by Nelson H. F. Beebe in |
| 2740 | <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>. |
| 2741 | |
| 2742 | * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that |
| 2743 | "$CC -E foo.h" is allowed, as this doesn't work with the Portland |
| 2744 | Group compiler. Instead, use "$CC -E bar.c". Include the .h |
| 2745 | file twice in the grammar, as an extra check. |
| 2746 | |
| 2747 | * tests/input.at (Torturing the Scanner): Surround the |
| 2748 | backslash-newline tests with "#if 0", to make it less likely that |
| 2749 | we'll run into compiler bugs. Bring back solitary \ inside |
| 2750 | comment, but add a closing comment to work around HP C bug. Don't |
| 2751 | test backslash-newline in C character constant. |
| 2752 | |
| 2753 | 2002-11-14 Akim Demaille <akim@epita.fr> |
| 2754 | |
| 2755 | * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit |
| 2756 | status of the compiler. |
| 2757 | Calling `exit 1' is no longer needed. |
| 2758 | Reported by Nelson H. F. Beebe. |
| 2759 | |
| 2760 | 2002-11-14 Akim Demaille <akim@epita.fr> |
| 2761 | |
| 2762 | * tests/atlocal.in (CPPFLAGS): We have config.h. |
| 2763 | * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR): |
| 2764 | New. |
| 2765 | * tests/actions.at, tests/calc.at, tests/conflicts.at, |
| 2766 | * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at, |
| 2767 | * tests/regression.at, tests/torture.at: Use them for all the |
| 2768 | grammars that are to be compiled. |
| 2769 | * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as... |
| 2770 | * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this. |
| 2771 | * doc/bison.texinfo (GLR Parsers): Document `inline'. |
| 2772 | |
| 2773 | 2002-11-14 Akim Demaille <akim@epita.fr> |
| 2774 | |
| 2775 | * doc/bison.texinfo: Various formatting changes (alignments in |
| 2776 | samples, additional @group/@end group, GCS in samples. |
| 2777 | Use @deffn instead of simple @table to define the directives, |
| 2778 | macros, variables etc. |
| 2779 | |
| 2780 | 2002-11-13 Paul Eggert <eggert@twinsun.com> |
| 2781 | |
| 2782 | Fix some bugs reported by Albert Chin-A-Young in |
| 2783 | <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>. |
| 2784 | |
| 2785 | * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c |
| 2786 | -o c"; the HP C compiler chatters during compilation. |
| 2787 | Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c". |
| 2788 | * tests/headers.at (export YYLTYPE): Likewise. |
| 2789 | |
| 2790 | * tests/input.at (Torturing the Scanner): Remove lines containing |
| 2791 | solitary backslashes, as they tickle a bug in the HP C compiler. |
| 2792 | |
| 2793 | * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid // |
| 2794 | comments, since they're not portable. Use GNU coding style. |
| 2795 | |
| 2796 | 2002-11-13 Akim Demaille <akim@epita.fr> |
| 2797 | |
| 2798 | * data/yacc.c: Leave bigger chunks of quoted text. |
| 2799 | (YYDSYMPRINTF): New. |
| 2800 | Use it to report symbol activities. |
| 2801 | * data/glr.c (YYDSYMPRINTF): New. |
| 2802 | Use it. |
| 2803 | |
| 2804 | 2002-11-12 Paul Eggert <eggert@twinsun.com> |
| 2805 | |
| 2806 | Version 1.75b. |
| 2807 | |
| 2808 | * data/glr.c (yydoAction): Return YYRESULTTAG, not int. |
| 2809 | (yyglrReduce): Return yyok, not 0. |
| 2810 | This should avoid the enumerated-type warnings reported |
| 2811 | by Nelson H. F. Beebe in |
| 2812 | <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>. |
| 2813 | |

| 2815 | * lib/bitset.h [! BITSET_INLINE]: Remove. |
| 2816 | (bitset_set, bitset_reset, bitset_test): Rename local vars |
| 2817 | to avoid shadowing warnings by GCC. |
| 2818 | |
| 2819 | * data/glr.c (inline): Remove #define. It's the user's |
| 2820 | responsibility to #define it away, just like 'const'. |
| 2821 | This fixes one of the bugs reported by Nelson H. F. Beebe in |
| 2822 | <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>. |
| 2823 | |
| 2824 | * Makefile.maint (po-check): Scan .l and .y files instead of the |
| 2825 | .c and the .h files that they generate. This fixes the bug |
| 2826 | reported by Tim Van Holder in: |
| 2827 | <http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00062.html> |
| 2828 | Look for N_ as well as for _. Try to avoid matching #define for |
| 2829 | N_ and _. |
| 2830 | * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c, |
| 2831 | src/system.h. Add src/parse-gram.y, src/scan-gram.l. |
| 2832 | * src/scan-gram.l: Revamp regular expressions so that " and ' |
| 2833 | do not confuse xgettext. |
| 2834 | |
| 2835 | * src/struniq.h (struniq_new): Do not declare the return type |
| 2836 | to be 'const'; this violates the C standard. |
| 2837 | * src/struniq.c (struniq_new): Likewise. |
| 2838 | |
| 2839 | 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com> |
| 2840 | |
| 2841 | * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the |
| 2842 | duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq |
| 2843 | linker. |
| 2844 | |
| 2845 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 2846 | |
| 2847 | * Makefile.maint: Sync with Autoconf: |

| 2849 | |
| 2850 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 2851 | |
| 2852 | * po/POTFILES.in (src/lalr.c, src/state.c): Remove |
| 2853 | |
| 2854 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 2855 | |
| 2856 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the |
| 2857 | locations. |
| 2858 | |
| 2859 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 2860 | |
| 2861 | * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT, |
| 2862 | not yyvalue. |
| 2863 | |
| 2864 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 2865 | |
| 2866 | * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New. |
| 2867 | Use it to test the GLR parser. |
| 2868 | |
| 2869 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 2870 | |
| 2871 | * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton |
| 2872 | defines it. |
| 2873 | * data/glr.c (yystos): New. |
| 2874 | (b4_yysymprint_generate, b4_yydestruct_generate): Invoke. |
| 2875 | (YYDSYMPRINT): New. |
| 2876 | (yyval): Don't define it, it is handled via M4. |
| 2877 | (yyrecoverParseError): Free verbosely the discarded symbols. |
| 2878 | * data/yacc.c (yysymprint): Remove, rather... |
| 2879 | (b4_yysymprint_generate): invoke. |
| 2880 | * data/c.m4 (b4_yysymprint_generate): New. |
| 2881 | Accept pointers as arguments, as opposed to the version from |
| 2882 | yacc.c. |
| 2883 | (b4_yydestruct_generate): Likewise. |
| 2884 | * tests/cations.at (Printers and Destructors): Use Bison directives |
| 2885 | instead of CPP macros. |
| 2886 | Don't rely on internal details. |
| 2887 | |
| 2888 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 2889 | |
| 2890 | * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New. |
| 2891 | * data/yacc.c: Rename yychar1 as yytoken, as in glr.c. |
| 2892 | Don't work on yychar (i.e., do set it to YYEMPTY, don't match |
| 2893 | it against YYEMPTY and so forth), work on yytoken (i.e., set |
| 2894 | it to YYEMPTY etc.). |

| 2925 | * data/c.m4 (b4_epilogue): Defaults to empty. |

| 2937 | * src/struniq.h, src/struniq.c (struniq_t): Is const. |
| 2938 | (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New. |
| 2939 | |

| 2969 | |
| 2970 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 2971 | |
| 2972 | * src/symtab.c (symbol_free): Remove dead deactivated code: |

| 2983 | 2002-11-11 Paul Eggert <eggert@twinsun.com> |
| 2984 | |
| 2985 | Revamp to fix many (but not all) of the C- and M4-related quoting |
| 2986 | problems. Among other things, this fixes the Bison bug reported |
| 2987 | by Jan Hubicka when processing the Bash grammar; see: |
| 2988 | <http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00039.html> |
| 2989 | |
| 2990 | Use new @ escapes consistently. Represent brackets with @{ and @} |
| 2991 | rather than @<:@ and @:>@, since this works a bit better with dumb |
| 2992 | editors like vi. Represent @ with @@, since @ is now consistently |
| 2993 | an escape. Use @oline@ and @ofile@ rather than __oline__ and |
| 2994 | __ofile__, to avoid unexpected expansions. Similarly, use @output |
| 2995 | rather than #output. |
| 2996 | |
| 2997 | * data/c.m4 (b4_copyright): Omit file name from comment, since |
| 2998 | the file name could contain "*/". |
| 2999 | (b4_synclines_flag): Don't quote the 2nd argument; it should already |
| 3000 | be quoted. All uses changed. |
| 3001 | |
| 3002 | * data/glr.c: Use new @ escapes consistently. |
| 3003 | (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name, |
| 3004 | b4_output_header_suffix, b4_output_header_name, b4_header_guard): |
| 3005 | Remove, since they couldn't handle arbitrary characters in file |
| 3006 | names. |
| 3007 | * data/lalr1.cc: Likewise. |
| 3008 | * data/yacc.c: Likewise. |
| 3009 | |
| 3010 | * src/files.c (output_infix): Remove; all uses removed. |
| 3011 | * src/files.h: Likewise. |
| 3012 | |
| 3013 | * data/glr.c: Remove use of "#ifdef b4_header_guard", since it |
| 3014 | mishandled funny characters in file names, and anyway it isn't |
| 3015 | needed any more. |
| 3016 | * data/yacc.c: Likewise. |
| 3017 | * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard. |
| 3018 | |
| 3019 | * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would. |
| 3020 | * data/yacc.c: Likewise. |
| 3021 | |
| 3022 | * src/muscle_tab.c: Include quotearg.h, since we need to quote C |
| 3023 | strings now. |
| 3024 | (muscle_init): Quote filename as a C string. |
| 3025 | * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused. |
| 3026 | (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros. |
| 3027 | * src/output.c (escaped_file_name_output): New function. |
| 3028 | (prepare_symbols): Quote tokens for M4. |
| 3029 | (prepare): Don't insert output_infix, output_prefix, |
| 3030 | output_parser_name, output_header_name; this is now down by scan-skel. |
| 3031 | Insert skeleton as a C string. |
| 3032 | |
| 3033 | * src/output.c (user_actions_output, symbol_destructors_output, |
| 3034 | symbol_printers_output): Quote filenames for C and M4. |
| 3035 | * src/reader.c (prologue_augment, epilogue_set): Likewise. |
| 3036 | |
| 3037 | * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash |
| 3038 | escapes other than \\ and \'; this simplifies the code. |
| 3039 | (<SC_STRING>): Likewise, for \\ and \". |
| 3040 | (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE, |
| 3041 | SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too. |
| 3042 | Use new escapes @{ and @} for [ and ]. |
| 3043 | |
| 3044 | * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing |
| 3045 | them with auto vars. |
| 3046 | Switch to new escape scheme, where @ is the escape character uniformly. |
| 3047 | Abort if a stray escape character is found. Avoid unbounded input |
| 3048 | buffer when parsing non-escaped text. |
| 3049 | |
| 3050 | * tests/input.at (Torturing the Scanner): Add tests that @oline@, |
| 3051 | __oline__, #output, $@, and @{ do not have unintended meanings. |
| 3052 | |
| 3053 | 2002-11-09 Paul Eggert <eggert@twinsun.com> |
| 3054 | |
| 3055 | Fix the test failure due to GCC warnings described in |
| 3056 | <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>. |
| 3057 | * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which |
| 3058 | evaluate to 0 if it's impossible for NINF to be in the respective |
| 3059 | table. |
| 3060 | (yygetLRActions, yyrecoverParseError): Use them. |
| 3061 | |
| 3062 | * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were |
| 3063 | counted in the token inserted at end of file. Now takes |
| 3064 | location_t *, not location_t, so that the location can be |
| 3065 | adjusted. All uses changed. |
| 3066 | |
| 3067 | * tests/regression.at (Invalid inputs): Adjust wording in |
| 3068 | diagnostic to match the new behavior. |
| 3069 | |
| 3070 | * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR, |
| 3071 | AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR, |
| 3072 | AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x)) |
| 3073 | abort ();'. This reduces the runtime of the "Many lookaheads" |
| 3074 | test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running |
| 3075 | GCC 3.2. |
| 3076 | |
| 3077 | 2002-11-07 Paul Eggert <eggert@twinsun.com> |
| 3078 | |
| 3079 | * src/parse-gram.y (CHARACTER): Remove unused token. |
| 3080 | All uses removed. |
| 3081 | |
| 3082 | * src/scan-gram.l: Remove stack option. We no longer use the |
| 3083 | stack, since the stack was never deeper than 1; instead, use the |
| 3084 | new auto var c_context to record the stacked value. |
| 3085 | |
| 3086 | Remove nounput option. At an unexpected end of file, we now unput |
| 3087 | the minimal input necessary to end cleanly; this simplifies the |
| 3088 | code. |
| 3089 | |
| 3090 | Avoid unbounded token sizes where this is easy. |
| 3091 | |
| 3092 | (unexpected_end_of_file): New function. |
| 3093 | Use it to systematize the error message on unexpected EOF. |
| 3094 | (last-string): Now auto, not static. |
| 3095 | (YY_OBS_FREE): Remove unnecessary do while (0) wrapper. |
| 3096 | (scanner_last_string_free): Remove; not used. |
| 3097 | (percent_percent_count): Move decl to just before use. |
| 3098 | (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file, |
| 3099 | not the (never otherwised-used) CHARACTER. |
| 3100 | |
| 3101 | 2002-11-07 Akim Demaille <akim@epita.fr> |
| 3102 | |
| 3103 | Let yyerror always receive the msg as last argument, so that |
| 3104 | yyerror can be variadic. |
| 3105 | |
| 3106 | * data/yacc.c (b4_yyerror_args): New. |
| 3107 | Use it when calling yyerror. |

| 3120 | Quote __ofile__. |
| 3121 | * src/output.c (symbol_printers_output) |

| 3136 | * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline. |
| 3137 | * src/output.c (user_actions_output): Likewise. |
| 3138 | (prepare): Define 'b4_synclines_flag'. |

| 3154 | either has GLR conflict entries. |
| 3155 | |
| 3156 | 2002-11-05 Paul Eggert <eggert@twinsun.com> |
| 3157 | |
| 3158 | * src/scan-gram.l: Use more accurate diagnostics, e.g. |
| 3159 | "integer out of range" rather than "invalid value". |
| 3160 | * tests/input.at (Invalid $n, Invalid @n): Change expected wording |
| 3161 | accordingly. |
| 3162 | |
| 3163 | Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires. |
| 3164 | Also, remove one static variable in the scanner. |
| 3165 | |
| 3166 | * src/scan-gram.l (braces_level): Now auto, not static. |
| 3167 | Initialize to zero if the compiler is being picky. |
| 3168 | (INITIAL): Clear braces_level instead of incrementing it. |
| 3169 | (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code, |
| 3170 | as POSIX 1003.1-2001 requires. |
| 3171 | * src/system.h (IF_LINT): New macro, taken from coreutils. |

| 3173 | |
| 3174 | 2002-11-05 Akim Demaille <akim@epita.fr> |
| 3175 | |
| 3176 | * src/scan-gram.l: When it starts with `%', complain about the |
| 3177 | whole directive, not just that `invalid character: %'. |
| 3178 | |
| 3179 | 2002-11-04 Akim Demaille <akim@epita.fr> |
| 3180 | |
| 3181 | * Makefile.maint: Update from Autoconf. |

| 3255 | to count columns correctly, and to check for invalid inputs. |
| 3256 | |
| 3257 | Use mbsnwidth to count columns correctly. Account for tabs, too. |
| 3258 | Include mbswidth.h. |
| 3259 | (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS. |
| 3260 | (extend_location): New function. |
| 3261 | (YY_LINES): Remove. |
| 3262 | |
| 3263 | Handle CRLF in C code rather than in Lex code. |
| 3264 | (YY_INPUT): New macro. |
| 3265 | (no_cr_read): New function. |
| 3266 | |
| 3267 | Scan UCNs, even though we don't fully handle them yet. |
| 3268 | (convert_ucn_to_byte): New function. |
| 3269 | |
| 3270 | Handle backslash-newline correctly in C code. |
| 3271 | (SC_LINE_COMMENT, SC_YACC_COMMENT): New states. |
| 3272 | (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.; |
| 3273 | all uses changed. |
| 3274 | (tag, splice): New EREs. Do not allow NUL or newline in tags. |
| 3275 | Use {splice} wherever C allows backslash-newline. |
| 3276 | YY_STEP after space, newline, vertical-tab. |
| 3277 | ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT). |
| 3278 | |
| 3279 | (letter, id): Don't assume ASCII; e.g., spell out a-z. |
| 3280 | |
| 3281 | ({int}, handle_action_dollar, handle_action_at): Check for integer |
| 3282 | overflow. |
| 3283 | |
| 3284 | (YY_STEP): Omit trailing semicolon, so that it's more like C. |
| 3285 | |
| 3286 | (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00 |
| 3287 | as well as \000. Check for UCHAR_MAX, not 255. |
| 3288 | Allow \x with an arbitrary positive number of digits, as in C. |
| 3289 | Check for overflow here. |
| 3290 | Allow \? and UCNs, for compatibility with C. |
| 3291 | |
| 3292 | (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision |
| 3293 | with quote slot used by complain_at. |
| 3294 | |
| 3295 | * tests/input.at: Add tests for backslash-newline, m4 quotes |
| 3296 | in symbols, long literals, and funny escapes in strings. |
| 3297 | |
| 3298 | * configure.ac (jm_PREREQ_MBSWIDTH): Add. |
| 3299 | * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c. |
| 3300 | * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext. |
| 3301 | * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4. |
| 3302 | * m4/mbswidth.m4: New file, from GNU coreutils. |
| 3303 | |
| 3304 | * doc/bison.texinfo (Grammar Outline): Document // comments. |
| 3305 | (Symbols): Document that trigraphs have no special meaning in Bison, |
| 3306 | nor is backslash-newline allowed. |
| 3307 | (Actions): Document that trigraphs have no special meaning. |
| 3308 | |
| 3309 | * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove; |
| 3310 | no longer used. |
| 3311 | |
| 3312 | 2002-11-02 Paul Eggert <eggert@twinsun.com> |
| 3313 | |
| 3314 | * src/reader.c: Don't include quote.h; not needed. |
| 3315 | (get_merge_function): Reword warning to be consistent with |
| 3316 | type clash diagnostic in grammar_current_rule_check. |
| 3317 | |
| 3318 | * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two |
| 3319 | bug in trigraph handling. |
| 3320 | |
| 3321 | * src/output.c (prepare_symbols): When printing token names, |
| 3322 | escape "[" as "@<:@" and likewise for "]". |
| 3323 | |
| 3324 | * src/system.h (errno): Remove declaration, as we are now |
| 3325 | assuming C89 or better, and C89 guarantees errno. |
| 3326 | |
| 3327 | 2002-10-30 Paul Eggert <eggert@twinsun.com> |
| 3328 | |
| 3329 | * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write): |
| 3330 | Check for close failures. |
| 3331 | * src/files.h (xfclose): Return void, not int, since it always |
| 3332 | returned zero. |
| 3333 | * src/files.c (xfclose): Likewise. Report I/O error if ferror |
| 3334 | indicates one. |
| 3335 | * src/output.c (output_skeleton): Use xfclose rather than fclose |
| 3336 | and ferror. xfclose now checks ferror. |
| 3337 | |
| 3338 | * data/glr.c (YYLEFTMOST_STATE): Remove. |
| 3339 | (yyreportTree): Use a stack-based leftmost state. This avoids |
| 3340 | our continuing battles with bogus warnings about initializers. |
| 3341 | |
| 3342 | 2002-10-30 Akim Demaille <akim@epita.fr> |
| 3343 | |
| 3344 | * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only |
| 3345 | #if. |
| 3346 | |
| 3347 | 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU> |
| 3348 | |
| 3349 | * tests/glr-regr1.at: New test for reported regressions. |
| 3350 | * tests/testsuite.at: Add glr-regr1.at test. |
| 3351 | * tests/Makefile.am: Add glr-regr1.at test. |
| 3352 | |
| 3353 | 2002-10-24 Paul Eggert <eggert@twinsun.com> |
| 3354 | |
| 3355 | Version 1.75a. |
| 3356 | |
| 3357 | * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration. |
| 3358 | * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since |
| 3359 | we use malloc. Don't assume 'A' through 'Z' are contiguous. |
| 3360 | Don't assume strdup exists; POSIX says its an XSI extension. |
| 3361 | Check for buffer overflow on input. |
| 3362 | |
| 3363 | 2002-10-24 Akim Demaille <akim@epita.fr> |
| 3364 | |
| 3365 | * src/output.c (output_skeleton): Don't disable M4sugar comments |
| 3366 | too soon: it results in comments being expanded. |
| 3367 | * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the |
| 3368 | first output. |
| 3369 | |
| 3370 | 2002-10-24 Akim Demaille <akim@epita.fr> |
| 3371 | |
| 3372 | * data/yacc.c (m4_int_type): New. |
| 3373 | * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed |
| 3374 | char' as only yacc.c wants K&R portability. |
| 3375 | * data/glr.c (yysigned_char): Remove. |
| 3376 | * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name. |
| 3377 | Reported by Quoc Peyrot. |
| 3378 | |
| 3379 | 2002-10-23 Paul Eggert <eggert@twinsun.com> |
| 3380 | |
| 3381 | * src/main.c (main): With --trace=time, report times even if a |
| 3382 | non-fatal error occurs. Formerly, the times were reported in some |
| 3383 | such cases but not in others. |
| 3384 | * src/reader.c (reader): Just return if a complaint has been issued, |
| 3385 | instead of exiting, so that 'main' can report times. |
| 3386 | |
| 3387 | 2002-10-22 Akim Demaille <akim@epita.fr> |
| 3388 | |
| 3389 | * src/system.h: Include sys/types. |
| 3390 | Reported by Bert Deknuydt. |
| 3391 | |
| 3392 | 2002-10-23 Paul Eggert <eggert@twinsun.com> |
| 3393 | |
| 3394 | * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX. |
| 3395 | Suggested by Art Haas. |
| 3396 | |
| 3397 | 2002-10-22 Paul Eggert <eggert@twinsun.com> |
| 3398 | |
| 3399 | * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit |
| 3400 | decl; not needed any more. |
| 3401 | * src/main.c (main): Use return to exit, undoing yesterday's change. |
| 3402 | The last OS that we could find where this wouldn't work is |
| 3403 | SunOS 3.5, and that's too old to worry about now. |
| 3404 | |
| 3405 | * data/glr.c (struct yyltype): Define members even when not |
| 3406 | doing locations. This is more consistent with yacc.c, and it |
| 3407 | works around the following bug reports: |
| 3408 | http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00106.html |
| 3409 | http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00111.html |
| 3410 | |
| 3411 | * doc/bison.texinfo: Minor spelling and typographical fixes. Use |
| 3412 | @acronym consistently. Standardize on "Yacc" instead of "YACC", |
| 3413 | "Algol" instead of "ALGOL". Give a bit more history about BNF. |
| 3414 | |
| 3415 | 2002-10-22 Akim Demaille <akim@epita.fr> |
| 3416 | |
| 3417 | * data/README: New. |
| 3418 | |
| 3419 | 2002-10-21 Paul Eggert <eggert@twinsun.com> |
| 3420 | |
| 3421 | Be consistent about 'bool'; the old code used an enum in one |
| 3422 | module and an int in another, and this violates the C standard. |
| 3423 | * m4/stdbool.m4: New file, from coreutils 4.5.3. |
| 3424 | * configure.ac (AC_HEADER_STDBOOL): Add. |
| 3425 | * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4. |
| 3426 | * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a) |
| 3427 | * src/symtab.c (hash_compare_symbol_t): Likewise. |
| 3428 | * src/system.h (bool, false, true): Use a definition consistent |
| 3429 | with ../lib/hash.c. All uses changed. |
| 3430 | |
| 3431 | * src/complain.c (warning_issued): Renamed from warn_message_count, |
| 3432 | so that we needn't worry about integer overflow (!). |
| 3433 | Now of type bool. All uses changed. |
| 3434 | (complaint_issued): Renamed from complain_message_count; likewise. |
| 3435 | |
| 3436 | * src/main.c (main): Use exit to exit with failure. |
| 3437 | |
| 3438 | * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS |
| 3439 | rather than 1 and 0. |
| 3440 | * src/main.c (main): Likewise. |
| 3441 | * src/getargs.c (getargs): Likewise. |
| 3442 | * src/reader.c (reader): Likewise. |
| 3443 | |
| 3444 | * src/getarg.c (getargs): Remove duplicate code for |
| 3445 | "Try `bison --help'". |
| 3446 | |
| 3447 | * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2. |
| 3448 | What was that "2" for? |
| 3449 | |
| 3450 | * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)). |
| 3451 | * src/getargs.c (usage): Likewise. |
| 3452 | |
| 3453 | * src/getargs.c (getargs): When there are too few operands, report |
| 3454 | the last one. When there are too many, report the first extra |
| 3455 | one. This is how diffutils does it. |
| 3456 | |
| 3457 | 2002-10-20 Paul Eggert <eggert@twinsun.com> |
| 3458 | |
| 3459 | Remove K&R vestiges. |
| 3460 | * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove. |
| 3461 | * src/complain.c (VA_START): Remove. Assume prototypes. |
| 3462 | (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro. |
| 3463 | (private_strerror, warn_at, warn, complain_at, complain, fatal_at, |
| 3464 | fatal): Assume prototypes. |
| 3465 | * src/complain.h: Assume prototypes. |
| 3466 | * src/system.h (PARAMS): Remove. |
| 3467 | Include <limits.h> unconditionally, since it's guaranteeed even |
| 3468 | for a freestanding C89 compiler. |
| 3469 | (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them. |
| 3470 | * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype. |
| 3471 | |
| 3472 | 2002-10-20 Akim Demaille <akim@epita.fr> |
| 3473 | |
| 3474 | * src/muscle_tab.c (muscle_grow): Remove trailing debugging code. |

| 3477 | (yyresolveStates, yyresolveAction, yyresolveStack) |
| 3478 | (yyprocessOneStack): Use them. |
| 3479 | (yy_reduce_print): New. |
| 3480 | * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param. |

| 3483 | |
| 3484 | * data/c.m4 (b4_c_ansi_args): Recognize functions with no |
| 3485 | arguments and output `void'. |
| 3486 | (b4_c_function): Rename as... |

| 3488 | (b4_c_function_decl, b4_c_ansi_function_def) |
| 3489 | (b4_c_ansi_function_decl): New. |
| 3490 | Change the interpretation of the arguments: before `int, foo', now |
| 3491 | `int foo, foo'. |
| 3492 | * data/yacc.c (yyparse): Prototype and define thanks to these. |
| 3493 | Adjust b4_c_function_def uses. |
| 3494 | * data/glr.c (yyparse): Likewise, but ANSI only. |
| 3495 | |
| 3496 | 2002-10-20 Akim Demaille <akim@epita.fr> |
| 3497 | |
| 3498 | * src/output.c (prepare): Move the definition of `tokens_number', |
| 3499 | `nterms_number', `undef_token_number', `user_token_number_max' |

| 3502 | (prepare_tokens): Rename as... |
| 3503 | (prepare_symbols): this. |
| 3504 | (prepare): Move the definition of `rules_number' to... |
| 3505 | (prepare_rules): here. |
| 3506 | (prepare): Move the definition of `last', `final_state_number', |
| 3507 | `states_number' to... |
| 3508 | (prepare_states): here. |
| 3509 | * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'. |
| 3510 | |
| 3511 | 2002-10-20 Akim Demaille <akim@epita.fr> |
| 3512 | |
| 3513 | * src/tables.h, src/tables.c, src/output.c: Comment changes. |

| 3517 | * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to... |
| 3518 | * data/c.m4: here. |
| 3519 | |
| 3520 | 2002-10-20 Akim Demaille <akim@epita.fr> |
| 3521 | |
| 3522 | * src/output.c (prepare): Use MUSCLE_INSERT_STRING. |
| 3523 | * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as |

| 3526 | `name' to... |
| 3527 | * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type) |
| 3528 | (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name): |
| 3529 | These. |
| 3530 | |
| 3531 | 2002-10-19 Paul Eggert <eggert@twinsun.com> |
| 3532 | |
| 3533 | Do not create a temporary file, as that involves security and |
| 3534 | cleanup headaches. Instead, use a pair of pipes. |
| 3535 | Derived from a suggestion by Florian Krohm. |
| 3536 | * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files. |
| 3537 | * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove. |

| 3545 | (m4_invoke): Remove decl. |
| 3546 | (scan_skel): New decl. |
| 3547 | (output_skeleton): Use pipe rather than temporary file for m4 input. |
| 3548 | Check that m4sugar.m4 is readable, to avoid deadlock. |
| 3549 | Check for pipe I/O error. |
| 3550 | * src/scan-skel.l (readpipe): Remove decl. |
| 3551 | (scan_skel): New function, to be used in place of m4_invoke. |
| 3552 | Read from stream rather than file. |
| 3553 | |
| 3554 | * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to |
| 3555 | float, as this generates a warning on Solaris 8 + GCC 3.2 with |
| 3556 | --enable-gcc-warnings. Instead, divide into 1.0 rather than 1; |
| 3557 | this generates a more-accurate value anyway. |
| 3558 | |
| 3559 | * lib/timevar.c (timervar_accumulate): Rename locals to |
| 3560 | avoid confusion with similarly-named more-global. |
| 3561 | * src/muscle_tab.c (muscle_pair_list_grow): Likewise. |
| 3562 | |
| 3563 | * src/output.c (prepare): Use xstrdup to convert char const * |
| 3564 | to char *, to avoid GCC warning. |

| 3567 | |
| 3568 | * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS, |
| 3569 | LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS. |
| 3570 | Use them to have `calc.y' ready for %pure-parser. |
| 3571 | * data/yacc.c (YYLEX): Pass a yylex return type to |
| 3572 | b4_c_function_call. |
| 3573 | |
| 3574 | 2002-10-19 Akim Demaille <akim@epita.fr> |
| 3575 | |
| 3576 | Prototype support of %lex-param and %parse-param. |
| 3577 | |
| 3578 | * src/parse-gram.y: Add the definition of the %lex-param and |
| 3579 | %parse-param tokens, plus their rules. |
| 3580 | Drop the `_' version of %glr-parser. |
| 3581 | Add the "," token. |

| 3586 | (muscle_entry_s): The `value' member is no longer const. |
| 3587 | Adjust all dependencies. |
| 3588 | * src/muscle_tab.c (muscle_init): Adjust: use |
| 3589 | MUSCLE_INSERT_STRING. |
| 3590 | Initialize the obstack earlier. |
| 3591 | * src/muscle_tab.h, src/muscle_tab.c (muscle_grow) |
| 3592 | (muscle_pair_list_grow): New. |
| 3593 | * data/c.m4 (b4_c_function_call, b4_c_args): New. |
| 3594 | * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param. |
| 3595 | * tests/calc.at: Use %locations, not --locations. |
| 3596 | (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser. |
| 3597 | |
| 3598 | 2002-10-19 Akim Demaille <akim@epita.fr> |
| 3599 | |
| 3600 | * src/getargs.c (usage): Take status as argument and exit |
| 3601 | accordingly. |
| 3602 | Report the traditional `Try ... --help' message when status != 0. |
| 3603 | (usage, version): Don't take a FILE * as arg, it is pointless. |
| 3604 | (getargs): When there is an incorrect number of arguments, make it |
| 3605 | an error, and report it GNUlically thanks to `usage ()'. |
| 3606 | |
| 3607 | 2002-10-18 Paul Eggert <eggert@twinsun.com> |
| 3608 | |
| 3609 | * data/glr.c (yyreportParseError): Don't assume that sprintf |
| 3610 | yields the length of the printed string, as this is not true |
| 3611 | on SunOS 4.1.4. Reported by Peter Klein. |
| 3612 | |
| 3613 | * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc. |
| 3614 | * tests/conflicts.at (%nonassoc and eof): Likewise. |
| 3615 | Fixes SunOS 4.1.4 test failure reported by Peter Klein. |
| 3616 | |
| 3617 | 2002-10-17 Akim Demaille <akim@epita.fr> |
| 3618 | |
| 3619 | * src/getargs.h (trace_e): Add trace_scan, and trace_parse. |
| 3620 | * src/getargs.c (trace_types, trace_args): Adjust. |
| 3621 | * src/reader.c (grammar_current_rule_prec_set) |
| 3622 | (grammar_current_rule_dprec_set, grammar_current_rule_merge_set): |
| 3623 | Standardize error messages. |
| 3624 | And s/@prec/%prec/! |
| 3625 | (reader): Use trace_flag to enable scanner/parser debugging, |
| 3626 | instead of an adhoc scheme. |

| 3634 | * NEWS: Officially drop support for building Bison with K&R C, |
| 3635 | since it didn't work anyway and it's not worth worrying about. |

| 3643 | |
| 3644 | Stop using the "enum_" trick for K&R-style function definitions; |
| 3645 | it confused me, and I was the author! Instead, assume that people |
| 3646 | who want to use K&R C compilers (when using these modules in GCC, |
| 3647 | perhaps?) will run ansi2knr. |
| 3648 | |
| 3649 | * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove. |

| 3739 | tests/cxx-type.at, tests/headers.at, tests/input.at, |

| 3741 | Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c", |

| 3748 | * data/glr.c (yysigned_char): New type. |

| 3753 | |

| 3755 | true due to limited range of data type" warning from GCC. |
| 3756 | |
| 3757 | * data/c.m4 (b4_token_defines): Protect against double-inclusion |
| 3758 | by wrapping enum yytokentype's definition inside #ifndef |
| 3759 | YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12. |

| 3779 | Let nondeterministic skeletons be usable with deterministic |
| 3780 | tables. |
| 3781 | |
| 3782 | With the patch, GAWK compiled by GCC without -O2 passes its test |
| 3783 | suite using a GLR parser driven by LALR tables. It fails with -O2 |
| 3784 | because `struct stat' gives two different answers on my machine: |
| 3785 | 88 (definition of an auto var) and later 96 (memset on this var). |
| 3786 | Hence the stack is badly corrumpted. The headers inclusion is to |
| 3787 | blame: if I move the awk.h inclusion before GLR's system header |
| 3788 | inclusion, the two struct stat have the same size. |
| 3789 | |
| 3790 | * src/tables.c (pack_table): Always create conflict_table. |
| 3791 | (token_actions): Always create conflict_list. |
| 3792 | * data/glr.c (YYFLAG): Remove, unused. |

| 3812 | GLR parsers sometimes raise parse errors instead of performing the |
| 3813 | default reduction. |
| 3814 | Reported by Charles-Henry de Boysson. |
| 3815 | |
| 3816 | * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't |
| 3817 | check the length of the traces when %glr. |
| 3818 | (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from |
| 3819 | GLR's traces. |
| 3820 | (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New. |
| 3821 | Test GLR parsers. |
| 3822 | * data/glr.c (YYLEFTMOST_STATE): Fix its value. |
| 3823 | (yyltype): Remove the yy prefix from the member names. |
| 3824 | (yytable): Complete its comment. |
| 3825 | (yygetLRActions): Map error action number from YYTABLE from |
| 3826 | YYTABLE_NINF to 0. |
| 3827 | (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF |
| 3828 | (which was a bug: it should have been YYTABEL_NINF, and yet it was |
| 3829 | not satisfying as we could compare an YYACTION computed from |
| 3830 | YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the |
| 3831 | only value for error actions. |
| 3832 | (yyreportParseError): In verbose parse error messages, don't issue |
| 3833 | `error' in the list of expected tokens. |
| 3834 | * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the |
| 3835 | next action to perform to match glr.c's decoding. |
| 3836 | (yytable): Complete its comment. |

| 3840 | Fix problem reported by Henrik Grubbstroem in |
| 3841 | <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>: |
| 3842 | "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected, |
| 3843 | because the Bison parser reads the second action before reducing |
| 3844 | the first one. |
| 3845 | * src/scan-gram.l (rule_length): New static var. |
| 3846 | Use it to keep track of the rule length in the scanner, since |
| 3847 | we can't expect the parser to be in lock-step sync with the scanner. |
| 3848 | (handle_action_dollar, handle_action_at): Use this var. |
| 3849 | * tests/actions.at (Exotic Dollars): Test for the problem. |
| 3850 | |

| 3853 | * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>. |
| 3854 | * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>. |
| 3855 | Include <sys/time.h> when checking for clock_t and struct tms. |
| 3856 | Use same include order as source. |
| 3857 | This is for the SunOS 4.1.4 porting bug reported by Peter Klein in |
| 3858 | <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>. |
| 3859 | |
| 3860 | * lib/timevar.c: Update copyright date and clarify comments. |
| 3861 | (get_time) [IN_GCC]: Keep the GCC version for reference. |
| 3862 | |
| 3863 | * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import |
| 3864 | GCC version as of today, then merge Bison's changes. |
| 3865 | Change "GCC" to "Bison" in copyright notice. timevar.def's |
| 3866 | author is Akim, so change that too. |
| 3867 | |
| 3868 | * src/reader.c (grammar_current_rule_check): |
| 3869 | Don't worry about the default action if $$ is untyped. |
| 3870 | Prevents bogus warnings reported by Jim Gifford in |
| 3871 | <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>. |
| 3872 | |
| 3873 | * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE. |
| 3874 | * data/glr.c, data/lalr1.cc, data/yacc.c: |
| 3875 | Output token definitions before the first part of user declarations. |
| 3876 | Fixes compatibility problem reported by Jim Gifford for kbd in |

| 3880 | |
| 3881 | * data/yacc.c (yyreport_parse_error): Remove, putting its body into... |
| 3882 | (yyparse): here. This undoes some of the 2002-07-25 change. |
| 3883 | Compatibility problem reported by Ralf S. Engelschall with |

| 3945 | All instances of parameters of type enum bitset_opts are now of |

| 3947 | for enum_bitset_type. |

| 3951 | Do not use "struct bitset_struct" to mean different things in |
| 3952 | different modules. Not only is this confusing, it violates |
| 3953 | the C Standard, which requires that structure types in different |

| 3999 | |
| 4000 | * lib/bitset.h (bitset_reset): Do not assume that bitset_word is |
| 4001 | the same width as int. This reapplies a hunk of the 2002-08-12 patch |

| 4313 | (bitset_test): Now returns int, not unsigned long. |
| 4314 | |
| 4315 | * lib/bitset_stats.c: Include "gettext.h". |
| 4316 | (_): New macro. |
| 4317 | (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't |
| 4318 | name locals "index", as it generates unnecessary warnings on some |
| 4319 | hosts that have an "index" function. |
| 4320 | |
| 4321 | * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print, |
| 4322 | bitset_stats_read, bitset_stats_write): Wrap strings in _() if |
| 4323 | they need translation. |
| 4324 | * src/LR0.c (state_list_append, new_itemsets, get_state, |

| 4342 | * po/POTFILES.in: Add src/assoc.c, src/closure.c, src/gram.c, |
| 4343 | src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c, |
| 4344 | lib/timevar.c. |
| 4345 | Use src/parse-gram.y instead of src/parse-gram.c, as the gettext |
| 4346 | manual recommends. |
| 4347 | Similarly, use src/scan-gram.l instead of src/scan-gram.c. |
| 4348 | |
| 4349 | * src/complain.c (strerror_r): Remove decl; not needed. |
| 4350 | (strerror): Use same pattern as ../lib/error.c. |

| 4353 | |
| 4354 | * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int. |
| 4355 | |
| 4356 | * src/main.c (main): Cast result of bindtextdomain and textdomain |
| 4357 | to void, to avoid a GCC warning when --disable-nls is in effect. |
| 4358 | |
| 4359 | * src/scan-gram.l: Use strings rather than escapes when possible, |
| 4360 | to minimize the number of warnings from xgettext. |
| 4361 | (handle_action_dollar, handle_action_at): Don't use isdigit, |
| 4362 | as it mishandles negative chars and it may not work as expected |
| 4363 | outside the C locale. |
| 4364 | |
| 4365 | * src/symtab.c (symbol_get): Don't cast LHS of an assignment; |
| 4366 | this is a GCC extension and is not portable to other compilers. |
| 4367 | |
| 4368 | * src/system.h (alloca): Use same pattern as ../lib/error.c. |
| 4369 | Do not include <ctype.h>; no longer needed. |
| 4370 | Do not include <malloc.h>; no longer needed (and generates |
| 4371 | warnings on OpenBSD 3.0). |
| 4372 | |
| 4373 | * tests/cxx-type.at (yylex): Do not pass signed char to isupper; |
| 4374 | it's not portable. |
| 4375 | |
| 4376 | * tests/regression.at: Do not use 'cc -c input.c -o input'; |
| 4377 | Sun C rejects this. Instead, use 'cc -c input.c -o input.o'. |
| 4378 | |
| 4379 | * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero |
| 4380 | exit status as failure, not just exit status 1. Sun C exits |
| 4381 | with status 2 sometimes. |
| 4382 | |
| 4383 | * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro. |
| 4384 | Use it for the two large tests. |
| 4385 | |

| 4387 | |
| 4388 | * src/conflicts.c (conflicts_output): Don't output rules never |

| 4404 | |
| 4405 | 2002-08-01 Akim Demaille <akim@epita.fr> |
| 4406 | |
| 4407 | Instead of attaching lookaheads and duplicating the rules being |
| 4408 | reduced by a state, attach the lookaheads to the reductions. |
| 4409 | |
| 4410 | * src/state.h (state_t): Remove the `lookaheads', |
| 4411 | `lookaheads_rule' member. |
| 4412 | (reductions_t): Add a `lookaheads' member. |
| 4413 | Use a regular array for the `rules'. |

| 4415 | to 0. |

| 4424 | (initialize_LA): this. |
| 4425 | (lalr_free): Adjust. |
| 4426 | * src/main.c (main): Don't free nullable and derives too early: it |
| 4427 | is used by --verbose. |
| 4428 | * src/print.c, src/print_graph.c, src/tables.c: Adjust. |
| 4429 | |
| 4430 | 2002-08-01 Akim Demaille <akim@epita.fr> |
| 4431 | |
| 4432 | * src/derives.h, src/derives.c (derives): A `rule_t***' instead of |
| 4433 | `rule_number_t**'. |

| 4446 | |
| 4447 | * lib/timevar.c (get_time): Include children time. |

| 4451 | * src/lalr.h, src/lalr.c (lalr_free): New. |
| 4452 | * src/main.c (main): Call it. |
| 4453 | * src/tables.c (pack_vector): Check whether loc is >= to the |
| 4454 | table_size, not >. |
| 4455 | (pack_tables): Don't free froms, tos, conflict_tos, and pos... |
| 4456 | (tables_generate): do it, since that's also it which allocates |
| 4457 | them. |
| 4458 | Don't free LA and LArule, main does. |
| 4459 | |
| 4460 | 2002-07-31 Akim Demaille <akim@epita.fr> |
| 4461 | |

| 4489 | |
| 4490 | * lib/timevar.c, lib/timevar.h, lib/timevar.def: New, |
| 4491 | stolen/adjusted from GCC. |
| 4492 | * m4/stage.m4: Remove time related checks. |

| 4506 | * src/getargs.h (enum trace_e): New. |
| 4507 | * src/getargs.c (trace_args, trace_types, trace_argmatch): New. |
| 4508 | (long_options, short_options): --trace/-T takes an optional |

| 4510 | Change all the uses of trace_flag to reflect the new flags. |
| 4511 | * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets. |
| 4512 | |
| 4513 | Strengthen `stage' portability. |
| 4514 | |
| 4515 | * m4/stage.m4 (BISON_PREREQ_STAGE): New. |
| 4516 | * configure.in: Use it. |

| 4520 | times and struct tms are available. |
| 4521 | |
| 4522 | 2002-07-30 Akim Demaille <akim@epita.fr> |

| 4545 | by conflicts. |
| 4546 | |
| 4547 | * src/LR0.c (save_reductions): Don't make the final state too |
| 4548 | different: save its reduction (accept) instead of having a state |
| 4549 | without any action (no shift or goto, no reduce). |
| 4550 | Note: the final state is now a ``regular'' state, i.e., the |
| 4551 | parsers now contain `reduce 0' as default reduction. |
| 4552 | Nevertheless, since they decide to `accept' when yystate = |
| 4553 | final_state, they still will not reduce rule 0. |
| 4554 | * src/print.c (print_actions, print_reduction): Adjust. |
| 4555 | * src/output.c (action_row): Track reduced rules. |
| 4556 | (token_actions): Report rules never reduced. |

| 4563 | |
| 4564 | * configure.in: Look for malloc.h and sys/times.h. |
| 4565 | * src/main.c (stage): Adjust. |
| 4566 | Report only when trace_flag. |
| 4567 | |
| 4568 | 2002-07-29 Akim Demaille <akim@epita.fr> |
| 4569 | |
| 4570 | * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not |

| 4586 | * doc/bison.texinfo (Table of Symbols): Mention $accept and $end. |
| 4587 | Adjust. |
| 4588 | |
| 4589 | 2002-07-29 Akim Demaille <akim@epita.fr> |
| 4590 | |
| 4591 | * src/reduce.c (reduce_grammar): When the language is empty, |
| 4592 | complain about the start symbol, not the axiom. |
| 4593 | Use its location. |
| 4594 | * tests/reduce.at (Empty Language): New. |
| 4595 | |
| 4596 | 2002-07-26 Akim Demaille <akim@epita.fr> |
| 4597 | |
| 4598 | * src/reader.h, src/reader.c (gram_error): ... can't get |
| 4599 | yycontrol without making too strong assumptions on the parser |
| 4600 | itself. |
| 4601 | * src/output.c (prepare_tokens): Use the real 0th value of |
| 4602 | token_translations instead of `0'. |

| 4604 | visible here. |
| 4605 | * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc |
| 4606 | for the time being: %locations ought to provide it to yyerror. |
| 4607 | |
| 4608 | 2002-07-25 Akim Demaille <akim@epita.fr> |
| 4609 | |
| 4610 | * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1. |

| 4613 | |

| 6204 | |
| 6205 | * data/bison.simple, data/bison.c++: Use `b4_pre_prologue' and |

| 6212 | (pre_prologue_obstack, post_prologue_obstack): New. |
| 6213 | * src/reader.c (copy_definition): Add a parameter to specify the |
| 6214 | obstack to fill, instead of using attrs_obstack unconditionally. |
| 6215 | (read_declarations): Pass pre_prologue_obstack to copy_definition if |
| 6216 | `%union' has not yet been seen, pass post_prologue_obstack otherwise. |
| 6217 | |
| 6218 | 2002-04-23 Paul Eggert <eggert@twinsun.com> |
| 6219 | |
| 6220 | * data/bison.simple: Remove unnecessary commentary and white |
| 6221 | space differences from 1_29-branch. |
| 6222 | Depend on YYERROR_VERBOSE, not defined (YYERROR_VERBOSE). |

| 6230 | |
| 6231 | 2002-04-23 Akim Demaille <akim@epita.fr> |
| 6232 | |
| 6233 | * tests/sets.at (AT_EXTRACT_SETS): Don't use 8 char long sed labels. |
| 6234 | * tests/synclines.at (AT_TEST_SYNCLINE): Be robust to GCC's |
| 6235 | location with columns. |
| 6236 | * tests/conflicts.at (%nonassoc and eof): Don't use `error.h'. |
| 6237 | All reported by Paul Eggert. |
| 6238 | |
| 6239 | 2002-04-22 Akim Demaille <akim@epita.fr> |
| 6240 | |
| 6241 | * src/reduce.c (dump_grammar): Move to... |
| 6242 | * src/gram.h, src/gram.c (grammar_dump): here. |
| 6243 | Be sure to separate long item numbers. |
| 6244 | Don't read the members of a rule's prec if its nil. |
| 6245 | |
| 6246 | 2002-04-22 Akim Demaille <akim@epita.fr> |
| 6247 | |

| 6249 | (MAXTABLE): Remove, replace uses with table_size. |
| 6250 | (pack_vector): Instead of dying when the table is too big, grow it. |
| 6251 | |
| 6252 | 2002-04-22 Akim Demaille <akim@epita.fr> |
| 6253 | |
| 6254 | * data/bison.simple (yyr1): Its type is that of a token number. |
| 6255 | * data/bison.c++ (r1_): Likewise. |

| 6257 | |
| 6258 | 2002-04-22 Akim Demaille <akim@epita.fr> |
| 6259 | |
| 6260 | * src/reader.c (token_translations_init): 256 is now the default |
| 6261 | value for the error token, i.e., it will be assigned another |
| 6262 | number if the user assigned 256 to one of her tokens. |
| 6263 | (reader): Don't force 256 to error. |
| 6264 | * doc/bison.texinfo (Symbols): Adjust. |
| 6265 | * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR) |
| 6266 | (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3 |
| 6267 | etc. instead of 10, 20, 30 (which was used to `jump' over error |
| 6268 | (256) and undefined (2)). |
| 6269 | |
| 6270 | 2002-04-22 Akim Demaille <akim@epita.fr> |
| 6271 | |
| 6272 | Propagate more token_number_t. |
| 6273 | |
| 6274 | * src/gram.h (token_number_as_item_number) |
| 6275 | (item_number_as_token_number): New. |
| 6276 | * src/output.c (GENERATE_OUTPUT_TABLE): New. |
| 6277 | Use it to create output_item_number_table and |

| 6279 | * src/LR0.c, src/derives.c, src/gram.c, src/gram.h, src/lalr.c, |
| 6280 | * src/lex.c, src/nullable.c, src/output.c, src/print.c, |
| 6281 | * src/print_graph.c, src/reader.c, src/reduce.c, src/state.h, |

| 6285 | |
| 6286 | * src/output.h, src/output.c (get_lines_number): Remove. |

| 6291 | as Lex/Flex'. |
| 6292 | (Debugging): More details about enabling the debugging features. |
| 6293 | (Table of Symbols): Describe $$, $n, @$, and @n. |
| 6294 | Suggested by Tim Josling. |
| 6295 | |
| 6296 | 2002-04-19 Akim Demaille <akim@epita.fr> |
| 6297 | |
| 6298 | * doc/bison.texinfo: Remove the uses of the obsolete @refill. |
| 6299 | |
| 6300 | 2002-04-10 Akim Demaille <akim@epita.fr> |
| 6301 | |
| 6302 | * src/system.h: Rely on HAVE_LIMITS_H. |
| 6303 | Suggested by Paul Eggert. |
| 6304 | |
| 6305 | 2002-04-09 Akim Demaille <akim@epita.fr> |
| 6306 | |
| 6307 | * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the |
| 6308 | full stderr, and strip it according to the bison options, instead |
| 6309 | of composing the error message from different bits. |
| 6310 | This makes it easier to check for several error messages. |
| 6311 | Adjust all the invocations. |
| 6312 | Add an invocation exercising the error token. |
| 6313 | Add an invocation demonstrating a stupid error message. |
| 6314 | (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0. |
| 6315 | Adjust the tests. |
| 6316 | Error message are for stderr, not stdout. |
| 6317 | |
| 6318 | 2002-04-09 Akim Demaille <akim@epita.fr> |
| 6319 | |
| 6320 | * src/gram.h, src/gram.c (error_token_number): Remove, use |
| 6321 | errtoken->number. |
| 6322 | * src/reader.c (reader): Don't specify the user token number (2) |
| 6323 | for $undefined, as it uselessly prevents using it. |
| 6324 | * src/gram.h (token_number_t): Move to... |
| 6325 | * src/symtab.h: here. |
| 6326 | (state_t.number): Is a token_number_t. |
| 6327 | * src/print.c, src/reader.c: Use undeftoken->number instead of |
| 6328 | hard coded 2. |
| 6329 | (Even though this 2 is not the same as above: the number of the |
| 6330 | undeftoken remains being 2, it is its user token number which |
| 6331 | might not be 2). |
| 6332 | * src/output.c (prepare_tokens): Rename the `maxtok' muscle with |
| 6333 | `user_token_number_max'. |
| 6334 | Output `undef_token_number'. |
| 6335 | * data/bison.simple, data/bison.c++: Use them. |
| 6336 | Be sure to map invalid yylex return values to |
| 6337 | `undef_token_number'. This saves us from gratuitous SEGV. |
| 6338 | |
| 6339 | * tests/conflicts.at (Solved SR Conflicts) |
| 6340 | (Unresolved SR Conflicts): Adjust. |
| 6341 | * tests/regression.at (Web2c Actions): Adjust. |
| 6342 | |
| 6343 | 2002-04-08 Akim Demaille <akim@epita.fr> |
| 6344 | |
| 6345 | * data/bison.c++: s/b4_item_number_max/b4_rhs_number_max/. |
| 6346 | Adding #line. |
| 6347 | Remove the duplicate `typedefs'. |
| 6348 | (RhsNumberType): Fix the declaration and various other typos. |
| 6349 | Use __ofile__. |
| 6350 | * data/bison.simple: Use __ofile__. |
| 6351 | * src/scan-skel.l: Handle __ofile__. |
| 6352 | |
| 6353 | 2002-04-08 Akim Demaille <akim@epita.fr> |
| 6354 | |
| 6355 | * src/gram.h (item_number_t): New, the type of item numbers in |
| 6356 | RITEM. Note that it must be able to code symbol numbers as |
| 6357 | positive number, and the negation of rule numbers as negative |
| 6358 | numbers. |
| 6359 | Adjust all dependencies (pretty many). |
| 6360 | * src/reduce.c (rule): Remove this `short *' pointer: use |
| 6361 | item_number_t. |
| 6362 | * src/system.h (MINSHORT, MAXSHORT): Remove. |
| 6363 | Include `limits.h'. |
| 6364 | Adjust dependencies to using SHRT_MAX and SHRT_MIN. |
| 6365 | (shortcpy): Remove. |
| 6366 | (MAXTABLE): Move to... |
| 6367 | * src/output.c (MAXTABLE): here. |
| 6368 | (prepare_rules): Use output_int_table to output rhs. |
| 6369 | * data/bison.simple, data/bison.c++: Adjust. |
| 6370 | * tests/torture.at (Big triangle): Move the limit from 254 to |
| 6371 | 500. |
| 6372 | * tests/regression.at (Web2c Actions): Ajust. |
| 6373 | |
| 6374 | Trying with bigger grammars shows various phenomena: at 3000 (28Mb |
| 6375 | of grammar file) bison is killed by my system, at 2000 (12Mb) bison |
| 6376 | passes, but produces negative #line number, once fixed, GCC is |
| 6377 | killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of |
| 6378 | C), it passes. |
| 6379 | * src/state.h (state_h): Code input lines on ints, not shorts. |
| 6380 | |
| 6381 | 2002-04-08 Akim Demaille <akim@epita.fr> |

| 6393 | * src/output.c (output_table_data): Return the longest number. |
| 6394 | (prepare_tokens): Output `token_number_max'). |
| 6395 | * data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type): |
| 6396 | New. |
| 6397 | Use them to define yy_token_number_type/TokenNumberType. |
| 6398 | Use this type for yytranslate. |
| 6399 | * tests/torture.at (Big triangle): Push the limit from 124 to |
| 6400 | 253. |
| 6401 | * tests/regression.at (Web2c Actions): Adjust. |

| 6422 | |
| 6423 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 6424 | |
| 6425 | Rename all the `bucket's as `symbol_t'. |

| 6439 | |
| 6440 | 2002-04-07 Akim Demaille <akim@epita.fr> |

| 6502 | As a result of the previous patch, it is no longer needed |
| 6503 | to reorder ritem itself. |
| 6504 | |
| 6505 | * src/reduce.c (reduce_grammar_tables): Don't sort RITEM. |
| 6506 | |
| 6507 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 6508 | |
| 6509 | Be sure never to walk through RITEMS, but use only data related to |
| 6510 | the rules themselves. RITEMS should be banished. |
| 6511 | |
| 6512 | * src/output.c (output_token_translations): Rename as... |
| 6513 | (prepare_tokens): this. |
| 6514 | In addition to `translate', prepare the muscles `tname' and |

| 6531 | Be sure to distinguish the initial from the final state. |
| 6532 | (new_states): Create the itemset of the initial state, and use |
| 6533 | new_state. |
| 6534 | * src/closure.c (closure): Now that the initial state has its |
| 6535 | items properly set, there is no need for a special case when |
| 6536 | creating `ruleset'. |
| 6537 | |
| 6538 | As a result, now the rule 0, reducing to $axiom, is visible in the |
| 6539 | outputs. Adjust the test suite. |
| 6540 | |
| 6541 | * tests/conflicts.at (Solved SR Conflicts) |

| 6953 | not expanded by m4. |
| 6954 | |
| 6955 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 6956 | |
| 6957 | * data/bison.c++: Adjust to the M4 back end. |
| 6958 | More is certainly needed. |
| 6959 | |
| 6960 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 6961 | |
| 6962 | Give a try to M4 as a back end. |
| 6963 | |
| 6964 | * lib/readpipe.c: New, from wdiff. |
| 6965 | * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and |
| 6966 | BISON_HAIRY. |
| 6967 | * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS |
| 6968 | specific values. Now it is m4 that performs the lookup. |
| 6969 | * src/parse-skel.y: Remove. |
| 6970 | * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New. |
| 6971 | * src/output.c (actions_output, guards_output) |
| 6972 | (token_definitions_output): No longer keeps track of the output |
| 6973 | line number, hence remove the second argument. |
| 6974 | (guards_output): Check against the guard member of a rule, not the |
| 6975 | action member. |
| 6976 | Adjust callers. |
| 6977 | (output_skeleton): Don't look for the skeleton location, let m4 do |
| 6978 | that. |
| 6979 | Create `/tmp/muscles.m4'. This is temporary, a proper temporary |
| 6980 | file will be used. |
| 6981 | Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton. |
| 6982 | (prepare): Given that for the time being changesyntax is not |
| 6983 | usable in M4, rename the muscles using `-' to `_'. |
| 6984 | Define `defines_flag', `output_parser_name' and `output_header_name'. |
| 6985 | * src/output.h (actions_output, guards_output) |
| 6986 | (token_definitions_output): Adjust prototypes. |
| 6987 | * src/scan-skel.l: Instead of scanning the skeletons, it now |
| 6988 | processes the output of m4: `__oline__' and `#output'. |
| 6989 | * data/bison.simple: Adjust to be used by M4(sugar). |
| 6990 | * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up |
| 6991 | to date. |
| 6992 | * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR' |
| 6993 | instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'. |
| 6994 | * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New, |
| 6995 | shamelessly stolen from CVS Autoconf. |
| 6996 | |
| 6997 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 6998 | |
| 6999 | * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version. |
| 7000 | * configure.in: Check for the declarations of free and malloc. |
| 7001 | * src/muscle_tab.c: Adjust. |
| 7002 | |
| 7003 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 7004 | |
| 7005 | * src/muscle_tab.c (muscle_init): Don't default to NULL muscle |
| 7006 | which have no values. |
| 7007 | |
| 7008 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 7009 | |
| 7010 | * src/bison.simple, src/bison.hairy, src/bison.c++: Move to... |
| 7011 | * data/: here. |
| 7012 | |
| 7013 | 2002-01-29 Paul Eggert <eggert@twinsun.com> |
| 7014 | |
| 7015 | * src/bison.simple (YYSIZE_T): Do not define merely because |
| 7016 | YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined. |
| 7017 | On some platforms, <alloca.h> does not declare YYSTD (size_t). |
| 7018 | |
| 7019 | 2002-01-27 Akim Demaille <akim@epita.fr> |
| 7020 | |
| 7021 | Fix `%nonassoc and eof'. |
| 7022 | |
| 7023 | * src/state.c (errs_dup): Aaaah! The failure was due to bytes |
| 7024 | which were not properly copied! Replace |
| 7025 | memcpy (res->errs, src->errs, src->nerrs); |
| 7026 | with |
| 7027 | memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0])); |
| 7028 | !!! |
| 7029 | * tests/regression.at (%nonassoc and eof): Adjust to newest |
| 7030 | Autotest: `.' is not in the PATH. |
| 7031 | |
| 7032 | 2002-01-27 Akim Demaille <akim@epita.fr> |
| 7033 | |
| 7034 | * tests/sets.at (AT_EXTRACT_SETS): New. |
| 7035 | (Nullable): Use it. |
| 7036 | (Firsts): New. |
| 7037 | |
| 7038 | 2002-01-26 Akim Demaille <akim@epita.fr> |
| 7039 | |
| 7040 | * tests/actions.at, tests/calc.at, tests/headers.at, |
| 7041 | * tests/torture.at: Adjust to the newest Autotest which no longer |
| 7042 | forces `.' in the PATH. |
| 7043 | |
| 7044 | 2002-01-25 Akim Demaille <akim@epita.fr> |
| 7045 | |
| 7046 | * tests/regression.at (%nonassoc and eof): New. |
| 7047 | Suggested by Robert Anisko. |
| 7048 | |
| 7049 | 2002-01-24 Akim Demaille <akim@epita.fr> |
| 7050 | |
| 7051 | Bison dumps core when trying to complain about broken input files. |
| 7052 | Reported by Cris van Pelt. |
| 7053 | |
| 7054 | * src/lex.c (parse_percent_token): Be sure to set token_buffer. |
| 7055 | * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge |
| 7056 | into... |
| 7057 | (Invalid inputs): Strengthen: exercise parse_percent_token. |
| 7058 | |
| 7059 | 2002-01-24 Robert Anisko <robert.anisko@epita.fr> |
| 7060 | |
| 7061 | * src/Makefile.am: Add bison.c++. |
| 7062 | * src/bison.c++: New skeleton. |
| 7063 | |
| 7064 | 2002-01-21 Paolo Bonzini <bonzini@gnu.org> |
| 7065 | |
| 7066 | * po/it.po: New. |
| 7067 | |
| 7068 | 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net> |
| 7069 | |
| 7070 | * src/files.c (skeleton_find) [MSDOS]: Fix cp definition. |
| 7071 | |
| 7072 | 2002-01-20 Marc Autret <marc@gnu.org> |
| 7073 | |
| 7074 | * src/files.c (compute_output_file_names): Fix |
| 7075 | |
| 7076 | 2002-01-20 Marc Autret <marc@gnu.org> |
| 7077 | |
| 7078 | * tests/output.at: New test. |
| 7079 | * src/files.c (compute_base_names): Don't map extensions when |
| 7080 | the YACC flag is set, use defaults. |
| 7081 | Reported by Evgeny Stambulchik. |
| 7082 | |
| 7083 | 2002-01-20 Marc Autret <marc@gnu.org> |
| 7084 | |
| 7085 | * src/system.h: Need to define __attribute__ away for non-GCC |
| 7086 | compilers as well (i.e. the vendor C compiler). |
| 7087 | Suggested by Albert Chin-A-Young. |
| 7088 | |
| 7089 | 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be> |
| 7090 | |
| 7091 | * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the |
| 7092 | canonical definition. |
| 7093 | * src/system.h: Use the canonical definition for PARAMS (avoids |
| 7094 | a conflict with the macro from lib/hash.h). |
| 7095 | |
| 7096 | 2002-01-11 Akim Demaille <akim@epita.fr> |
| 7097 | |
| 7098 | * configure.in: Use AC_FUNC_STRNLEN. |
| 7099 | Fixes the failures observed on AIX 4.3 by H.Merijn Brand. |
| 7100 | |
| 7101 | 2002-01-09 Akim Demaille <akim@epita.fr> |
| 7102 | |
| 7103 | * src/files.c, src/files.h (output_infix): New. |
| 7104 | (tab_extension): Remove. |
| 7105 | (compute_base_names): Compute the former, drop the latter. |
| 7106 | * src/output.c (prepare): Insert the muscles `output-infix', and |
| 7107 | `output-suffix'. |
| 7108 | * src/parse-skel.y (string, string.1): New. |
| 7109 | (section.header): Use it. |
| 7110 | (section.yacc): Remove. |
| 7111 | (prefix): Remove too. |
| 7112 | * src/scan-skel.l: Adjust. |
| 7113 | * src/bison.simple, src/bison.hairy: Adjust. |
| 7114 | |
| 7115 | 2002-01-09 Akim Demaille <akim@epita.fr> |
| 7116 | |
| 7117 | * configure.in (WERROR_CFLAGS): Compute it. |
| 7118 | * src/Makefile.am (CFLAGS): Pass it. |
| 7119 | * tests/atlocal.in (CFLAGS): Idem. |
| 7120 | * src/files.c: Fix a few warnings. |
| 7121 | (get_extension_index): Remove, unused. |
| 7122 | |
| 7123 | 2002-01-08 Akim Demaille <akim@epita.fr> |
| 7124 | |
| 7125 | * src/getargs.c (AS_FILE_NAME): New. |
| 7126 | (getargs): Use it to convert DOSish file names. |
| 7127 | * src/files.c (base_name): Rename as full_base_name to avoid |
| 7128 | clashes with `base_name ()'. |
| 7129 | (filename_split): New. |
| 7130 | (compute_base_names): N-th rewrite, using filename_split. |
| 7131 | |
| 7132 | 2002-01-08 Akim Demaille <akim@epita.fr> |
| 7133 | |
| 7134 | * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c: |
| 7135 | New, stolen from the Fileutils 4.1. |
| 7136 | * lib/Makefile.am (libbison_a_SOURCES): Adjust. |
| 7137 | * configure.in: Check for the presence of memrchr, and of its |
| 7138 | prototype. |
| 7139 | |
| 7140 | 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be> |
| 7141 | |
| 7142 | * lib/hash.h (__P): Added definition for this macro. |
| 7143 | * src/Makefile.am: Add parse-skel.c and scan-skel.c to |
| 7144 | BUILT_SOURCES, to ensure they are generated first. |
| 7145 | * src/parse-skel.y: Use YYERROR_VERBOSE instead of |
| 7146 | %error-verbose to allow bootstrapping with bison 1.30x. |
| 7147 | |
| 7148 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 7149 | |
| 7150 | * src/reader.c (parse_braces): Don't fetch the next char, the |
| 7151 | convention is to fetch on entry. |
| 7152 | * tests/torture.at (GNU Cim Grammar): Reintroduce their weird |
| 7153 | 'switch' without a following semicolon. |
| 7154 | * tests/regression.at (braces parsing): New. |
| 7155 | |
| 7156 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 7157 | |
| 7158 | Bison is dead wrong in its RR conflict reports. |
| 7159 | |
| 7160 | * tests/torture.at (GNU Cim Grammar): New. |
| 7161 | * src/conflicts.c (count_rr_conflicts): Fix. |
| 7162 | |
| 7163 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 7164 | |
| 7165 | Creating package.m4 from configure.ac causes too many problems. |
| 7166 | |
| 7167 | * tests/Makefile.am (package.m4): Create it by hand, |
| 7168 | AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf. |
| 7169 | |
| 7170 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 7171 | |
| 7172 | * src/Makefile.am (bison_SOURCES): Add parse-skel.h and |
| 7173 | skeleton.h. |
| 7174 | |
| 7175 | 2002-01-04 Paul Eggert <eggert@twinsun.com> |
| 7176 | |
| 7177 | * doc/bison.texinfo (Debugging): |
| 7178 | Remove YYSTDERR; it's no longer defined or used. |
| 7179 | Also, s/cstdio.h/cstdio/. |
| 7180 | |
| 7181 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 7182 | |
| 7183 | * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf. |
| 7184 | |
| 7185 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 7186 | |
| 7187 | * src/parse-skel.y (process_skeleton): Don't bind the parser's |
| 7188 | tracing code to --trace, wait for a better --trace option, with |
| 7189 | args. |
| 7190 | |
| 7191 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 7192 | |
| 7193 | * src/bison.simple (YYSTDERR): Remove, replace `stderr'. |
| 7194 | The ISO C++ standard is extremely clear about it: stderr is |
| 7195 | considered a macro, not a regular symbol (see table 94 `Header |
| 7196 | <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files). |
| 7197 | Therefore std:: does not apply to it. It still does with fprintf. |
| 7198 | Also, s/cstdio.h/cstdio/. |
| 7199 | |
| 7200 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 7201 | |
| 7202 | * lib/quotearg.c: Use `#include "..."' instead of `#include <...>' |
| 7203 | for non system headers. |
| 7204 | |
| 7205 | 2002-01-02 Akim Demaille <akim@epita.fr> |
| 7206 | |
| 7207 | Equip the skeleton chain with location tracking, runtime trace, |
| 7208 | pure parser and scanner. |
| 7209 | |
| 7210 | * src/parse-skel.y: Request a pure parser, locations, and prefix |
| 7211 | renaming. |
| 7212 | (%union): Having several members with the same type does not help |
| 7213 | type mismatches, simplify. |
| 7214 | (YYPRINT, yyprint): New. |
| 7215 | (yyerror): ``Rename'' (there is a #define yyerror skel_error) as... |
| 7216 | (skel_error): this. |
| 7217 | Handle locations. |
| 7218 | * src/scan-skel.l: Adjust to these changes. |
| 7219 | * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP) |
| 7220 | (LOCATION_PRINT, skel_control_t): New. |
| 7221 | |
| 7222 | 2001-12-30 Akim Demaille <akim@epita.fr> |
| 7223 | |
| 7224 | * src/parse-skel.y: Get rid of the shift/reduce conflict: |
| 7225 | replace `gb' with BLANKS. |
| 7226 | * src/scan-skel.l: Adjust. |
| 7227 | |
| 7228 | 2001-12-30 Akim Demaille <akim@epita.fr> |
| 7229 | |
| 7230 | * src/system.h: We don't need nor want bcopy. |
| 7231 | Throw away MS-DOS crap: we don't need getpid. |
| 7232 | * configure.in: We don't need strndup. It was even causing |
| 7233 | problems: because Flex includes the headers *before* us, |
| 7234 | _GNU_SOURCE is not defined by config.h, and therefore strndup was |
| 7235 | not visible. |
| 7236 | * lib/xstrndup.c: New. |
| 7237 | * src/scan-skel.l: Use it. |
| 7238 | Be sure to initialize yylval.muscle member when scanning a MUSCLE. |
| 7239 | * src/parse-skel.y: Use %directives instead of #defines. |
| 7240 | |
| 7241 | 2001-12-30 Akim Demaille <akim@epita.fr> |
| 7242 | |
| 7243 | * src/skeleton.h: New. |
| 7244 | * src/output.c (output_parser, output_master_parser): Remove, dead |
| 7245 | code. |
| 7246 | * src/output.h (get_lines_number, actions_output, guards_output) |
| 7247 | (token_definitions_output): Prototype them. |
| 7248 | * src/parse-skel.y: Add the license notice. |
| 7249 | Include output.h and skeleton.h. |
| 7250 | (process_skeleton): Returns void, and takes a single parameter. |
| 7251 | * src/scan-skel.l: Add the license notice. |
| 7252 | Include skeleton.h. |
| 7253 | Don't use %option yylineno: it seems that then Flex imagines |
| 7254 | REJECT has been used, and therefore it won't reallocate its |
| 7255 | buffers (which makes no other sense to me than a bug). It results |
| 7256 | in warnings for `unused: yy_flex_realloc'. |
| 7257 | |
| 7258 | 2001-12-30 Robert Anisko <robert.anisko@epita.fr> |
| 7259 | |
| 7260 | * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING) |
| 7261 | (MUSCLE_INSERT_PREFIX): ...to there. |
| 7262 | * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING) |
| 7263 | (MUSCLE_INSERT_PREFIX): Move from here... |
| 7264 | |
| 7265 | * src/bison.hairy: Add a section directive. Put braces around muscle |
| 7266 | names. This parser skeleton is still broken, but Bison should not |
| 7267 | choke on a bad muscle 'syntax'. |
| 7268 | * src/bison.simple: Add a section directive. Put braces around muscle |
| 7269 | names. |
| 7270 | |
| 7271 | * src/files.h (strsuffix, stringappend): Add declarations. |
| 7272 | (tab_extension): Add declaration. |
| 7273 | (short_base_name): Add declaration. |
| 7274 | |
| 7275 | * src/files.c (strsuffix, stringappend): No longer static. These |
| 7276 | functions are used in the skeleton parser. |
| 7277 | (tab_extension): New. |
| 7278 | (compute_base_names): Use the computations done in this function |
| 7279 | to guess if the generated parsers should have '.tab' in their |
| 7280 | names. |
| 7281 | (short_base_name): No longer static. |
| 7282 | |
| 7283 | * src/output.c (output_skeleton): New. |
| 7284 | (output): Disable call to output_master_parser, and give a try to |
| 7285 | a new skeleton handling system. |
| 7286 | (guards_output, actions_output): No longer static. |
| 7287 | (token_definitions_output, get_lines_number): No longer static. |
| 7288 | |
| 7289 | * configure.in: Use AM_PROG_LEX and AC_PROG_YACC. |
| 7290 | |
| 7291 | * src/Makefile.am (bison_SOURCES): Add scan-skel.l and |
| 7292 | parse-skel.y. |
| 7293 | |
| 7294 | * src/parse-skel.y: New file. |
| 7295 | * src/scan-skel.l: New file. |
| 7296 | |
| 7297 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7298 | |
| 7299 | %name-prefix is broken. |
| 7300 | |
| 7301 | * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy". |
| 7302 | Adjust all dependencies. |
| 7303 | * tests/headers.at (export YYLTYPE): Strengthen this test: use |
| 7304 | %name-prefix. |
| 7305 | |
| 7306 | Renaming yylval but not yylloc is not consistent. Now we do. |
| 7307 | |
| 7308 | * src/bison.simple: Prefix yylloc if used. |
| 7309 | * doc/bison.texinfo (Decl Summary): Document that. |
| 7310 | |
| 7311 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7312 | |
| 7313 | * doc/bison.texinfo: Promote `%long-directive' over |
| 7314 | `%long_directive'. |
| 7315 | Remove all references to fixed-output-files, yacc is enough. |
| 7316 | |
| 7317 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7318 | |
| 7319 | * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the |
| 7320 | user prologue. These are defaults. |
| 7321 | * tests/actions.at (Mid-rule actions): Make sure the user can |
| 7322 | define YYDEBUG and YYERROR_VERBOSE. |
| 7323 | |
| 7324 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7325 | |
| 7326 | * src/output.c (header_output): Don't forget to export YYLTYPE and |
| 7327 | yylloc. |
| 7328 | * tests/headers.at (export YYLTYPE): New, make sure it does. |
| 7329 | * tests/regression.at (%union and --defines, Invalid CPP headers): |
| 7330 | Move to... |
| 7331 | * tests/headers.at: here. |
| 7332 | |
| 7333 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7334 | |
| 7335 | * src/gram.h (rule_s): Member `assoc' is of type `associativity'. |
| 7336 | |
| 7337 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7338 | |
| 7339 | * tests/actions.at (Mid-rule actions): Output on a single line |
| 7340 | instead of several. |
| 7341 | |

| 7344 | * doc/bison.texinfo: Formatting changes. |
| 7345 | |
| 7346 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7347 | |
| 7348 | Don't store the token defs in a muscle, just be ready to output it |
| 7349 | on command. Now possible via `symbols'. Fixes a memory leak. |
| 7350 | |
| 7351 | * src/output.c (token_definitions_output): New. |
| 7352 | (output_parser, header_output): Use it. |
| 7353 | * src/reader.c (symbols_save): Remove. |
| 7354 | |
| 7355 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7356 | |
| 7357 | * src/bison.simple: Do not provide a default for YYSTYPE and |
| 7358 | YYLTYPE before the user's prologue. Otherwise it's hardly... a |
| 7359 | default. |
| 7360 | |
| 7361 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7362 | |
| 7363 | Mid-rule actions are simply... ignored! |
| 7364 | |
| 7365 | * src/reader.c (readgram): Be sure to attach mid-rule actions to |
| 7366 | the empty-rule associated to the dummy symbol, not to the host |
| 7367 | rule. |
| 7368 | * tests/actions.at (Mid-rule actions): New. |
| 7369 | |
| 7370 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7371 | |
| 7372 | Memory leak. |
| 7373 | |
| 7374 | * src/reader.c (reader): Free grammar. |
| 7375 | |
| 7376 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7377 | |
| 7378 | Memory leak. |
| 7379 | |
| 7380 | * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here, |
| 7381 | since it allocates it for each state, although only one is needed. |
| 7382 | (allocate_storage): Do it here. |
| 7383 | |
| 7384 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7385 | |
| 7386 | * src/options.h, src/options.c (create_long_option_table): Rename |
| 7387 | as... |
| 7388 | (long_option_table_new): this, with a clearer prototype. |
| 7389 | (percent_table): Remove, unused, |
| 7390 | * src/getargs.c (getargs): Adjust. |
| 7391 | |
| 7392 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7393 | |
| 7394 | * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c |
| 7395 | * src/print.c, src/print_graph.c, src/state.h: Rename state_table |
| 7396 | as states. |
| 7397 | |
| 7398 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7399 | |
| 7400 | * src/lalr.c (build_relations): Rename `states' as `states1'. |
| 7401 | Sorry, I don't understand exactly what it is, no better name... |
| 7402 | |
| 7403 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7404 | |
| 7405 | * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c |
| 7406 | * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c |
| 7407 | * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table |
| 7408 | as rules. |
| 7409 | |
| 7410 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7411 | |
| 7412 | * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long |
| 7413 | ago. |
| 7414 | |
| 7415 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7416 | |
| 7417 | * src/reader.c, src/reader.h (user_toknums): Remove. |
| 7418 | Adjust all users to use symbols[i]->user_token_number. |
| 7419 | |
| 7420 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7421 | |
| 7422 | * src/gram.c, src/gram.h (sprec, sassoc): Remove. |
| 7423 | Adjust all users to use symbols[i]->prec or ->assoc. |
| 7424 | |
| 7425 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7426 | |
| 7427 | * src/reader.c, src/reader.h (tags): Remove. |
| 7428 | Adjust all users to use symbols[i]->tag. |
| 7429 | |
| 7430 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7431 | |
| 7432 | * src/gram.h, src/gram.c (symbols): New, similar to state_table |
| 7433 | and rule_table. |
| 7434 | * src/reader.c (packsymbols): Fill this table. |
| 7435 | Drop sprec. |
| 7436 | * src/conflicts.c (resolve_sr_conflict): Adjust. |
| 7437 | * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a |
| 7438 | single table. |
| 7439 | Use symbols[i]->tag instead of tags[i]. |
| 7440 | |
| 7441 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7442 | |
| 7443 | * tests/calc.at (_AT_DATA_CALC_Y): Also use %union. |
| 7444 | In addition, put a comment in there, to replace... |
| 7445 | * tests/regression.at (%union and C comments): Remove. |
| 7446 | |
| 7447 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7448 | |
| 7449 | * tests/regression.at (Web2c Actions): Blindly move the actual |
| 7450 | output as expected output. The contents *seem* right to me, but I |
| 7451 | can't pretend reading perfectly parser tables... Nonetheless, all |
| 7452 | the other tests pass correctly, the table look OK, even though the |
| 7453 | presence of `$axiom' is to be noted: AFAICS it is useless (but |
| 7454 | harmless). |
| 7455 | |
| 7456 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7457 | |
| 7458 | * src/reader.c (readgram): Don't add the rule 0 if there were no |
| 7459 | rules read. In other words, add it _after_ having performed |
| 7460 | grammar sanity checks. |
| 7461 | Fixes the `tests/regression.at (Invalid input: 1)' Failure. |
| 7462 | |
| 7463 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7464 | |
| 7465 | * tests/regression.at (Web2c Report): Catch up: the rule 0 is now |
| 7466 | visible, and some states have now a different number. |
| 7467 | |
| 7468 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7469 | |
| 7470 | * src/reader.c (readgram): Bind the initial rule's lineno to that |
| 7471 | of the first rule. |
| 7472 | * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts): |
| 7473 | (Solved SR Conflicts): Adjust rule 0's line number. |
| 7474 | |
| 7475 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7476 | |
| 7477 | Fix the `GAWK Grammar' failure. |
| 7478 | |
| 7479 | * src/LR0.c (final_state): Initialize to -1 so that we do compute |
| 7480 | the reductions of the first state which was mistakenly confused |
| 7481 | with the final state because precisely final_state was initialized |
| 7482 | to 0. |
| 7483 | * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads, |
| 7484 | now noticed by Bison. |
| 7485 | * tests/regression.at (Rule Line Numbers): Adjust: state 0 does |
| 7486 | have a reduction on $default. |
| 7487 | |
| 7488 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7489 | |
| 7490 | * src/gram.c (ritem_print): Be sure to subtract 1 when displaying |
| 7491 | rule line numbers. |
| 7492 | * src/closure.c (print_closure): Likewise. |
| 7493 | * src/derives.c (print_derives): Likewise. |
| 7494 | * tests/sets.at (Nullable): Adjust: the rule numbers are correct |
| 7495 | now. |
| 7496 | |
| 7497 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7498 | |
| 7499 | * src/lalr.c (lookaheads_print): New. |
| 7500 | (lalr): Call it when --trace-flag. |
| 7501 | * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads |
| 7502 | are dumped. |
| 7503 | |
| 7504 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7505 | |
| 7506 | * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0', |
| 7507 | when walking through ritem, even via rule->rhs. |
| 7508 | * src/reduce.c (dump_grammar, useful_production, reduce_output) |
| 7509 | (useful_production, useless_nonterminals): Likewise. |
| 7510 | (reduce_grammar_tables): Likewise, plus update nritems. |
| 7511 | * src/nullable.c (set_nullable): Likewise. |
| 7512 | * src/lalr.c (build_relations): Likewise. |
| 7513 | * tests/sets.at (Nullable): Adjust. |
| 7514 | Fortunately, now, the $axiom is no longer nullable. |
| 7515 | |
| 7516 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7517 | |
| 7518 | * src/LR0.c (generate_states): Use nritems, not nitems, nor using |
| 7519 | the 0-sentinel. |
| 7520 | * src/gram.c (ritem_longest_rhs): Likewise. |
| 7521 | * src/reduce.c (nonterminals_reduce): Likewise. |
| 7522 | * src/print_graph.c (print_graph): Likewise. |
| 7523 | * src/output.c (output_rule_data): Likewise. |
| 7524 | * src/nullable.c (set_nullable): Likewise. |
| 7525 | |
| 7526 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 7527 | |
| 7528 | * src/output.c: Comment changes. |
| 7529 | |
| 7530 | 2001-12-27 Paul Eggert <eggert@twinsun.com> |
| 7531 | |
| 7532 | * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special |
| 7533 | cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and |
| 7534 | Sparc, as they were causing more porting problems than the |
| 7535 | (minor) performance improvement was worth. |
| 7536 | |
| 7537 | Also, catch up with 1.31's YYSTD. |
| 7538 | |
| 7539 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7540 | |
| 7541 | * src/output.c (output_gram): Rely on nritems, not the |
| 7542 | 0-sentinel. See below. |
| 7543 | Use -1 as separator, not 0. |
| 7544 | * src/bison.simple (yyparse): Subtract 1 to the rule numbers. |
| 7545 | Rely on -1 as separator in yyrhs, instead of 0. |
| 7546 | * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue |
| 7547 | twice `Now at end of input', therefore there are two lines less to |
| 7548 | expect. |
| 7549 | |
| 7550 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7551 | |
| 7552 | * tests/regression.at (Unresolved SR Conflicts): |
| 7553 | (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes |
| 7554 | below. |
| 7555 | |
| 7556 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7557 | |
| 7558 | * src/LR0.c (new_state): Recognize the final state by the fact it |
| 7559 | is reached by eoftoken. |
| 7560 | (insert_start_shifting_state, insert_eof_shifting_state) |
| 7561 | (insert_accepting_state, augment_automaton): Remove, since now |
| 7562 | these states are automatically computed from the initial state. |
| 7563 | (generate_states): Adjust. |
| 7564 | * src/print.c: When reporting a rule number to the user, substract |
| 7565 | 1, so that the axiom rule is rule 0, and the first user rule is 1. |
| 7566 | * src/reduce.c: Likewise. |
| 7567 | * src/print_graph.c (print_core): For the time being, just as for |
| 7568 | the report, depend upon --trace-flags to dump the full set of |
| 7569 | items. |
| 7570 | * src/reader.c (readgram): Once the grammar read, insert the rule |
| 7571 | 0: `$axiom: START-SYMBOL $'. |
| 7572 | * tests/set.at: Adjust: rule 0 is now displayed, and since the |
| 7573 | number of the states has changed (the final state is no longer |
| 7574 | necessarily the last), catch up. |
| 7575 | |
| 7576 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7577 | |
| 7578 | Try to make the use of the eoftoken valid. Given that its value |
| 7579 | is 0 which was also used as a sentinel in ritem, (i) make sure >= 0 |
| 7580 | is used instead of > 0 where appropriate, (ii), depend upon nritems |
| 7581 | instead of the 0-sentinel. |
| 7582 | |
| 7583 | * src/gram.h, src/gram.c (nritems): New. |
| 7584 | Expected to be duplication of nitems, but for the time being... |
| 7585 | * src/reader.c (packgram): Assert nritems and nitems are equal. |
| 7586 | * src/LR0.c (allocate_itemsets, new_itemsets): Adjust. |
| 7587 | * src/closure.c (print_closure, print_fderives): Likewise. |
| 7588 | * src/gram.c (ritem_print): Likewise. |
| 7589 | * src/print.c (print_core, print_grammar): Likewise. |
| 7590 | * src/print_graph.c: Likewise. |
| 7591 | |
| 7592 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7593 | |
| 7594 | * src/main.c (main): If there are complains after grammar |
| 7595 | reductions, then output the report anyway if requested, then die. |
| 7596 | * src/symtab.c (bucket_new): Initialize `value' to -1, not 0. |
| 7597 | * src/reader.c (eoftoken): New. |
| 7598 | (parse_token_decl): If the token being defined has value `0', it |
| 7599 | is the eoftoken. |
| 7600 | (packsymbols): No longer hack `tags' to insert `$' by hand. |
| 7601 | Be sure to preserve the value of the eoftoken. |
| 7602 | (reader): Make sure eoftoken is defined. |
| 7603 | Initialize nsyms to 0: now eoftoken is created just like the others. |
| 7604 | * src/print.c (print_grammar): Don't special case the eof token. |
| 7605 | * src/regression.at: Adjust: `$' has value 0, not -1, which was a |
| 7606 | lie anyway, albeit pleasant. |
| 7607 | * tests/calc.at: Exercise error messages with eoftoken. |
| 7608 | Change the grammar so that empty input is invalid. |
| 7609 | Adjust expectations. |
| 7610 | When yyungeting, be sure to use a valid yylloc: use last_yylloc. |
| 7611 | |
| 7612 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7613 | |
| 7614 | * configure.in: Check the protos of strchr ans strspn. |
| 7615 | Replace strchr if needed. |
| 7616 | * src/system.h: Provide the protos of strchr, strspn and memchr if |
| 7617 | missing. |
| 7618 | * lib/strchr.c: New. |
| 7619 | * src/reader.c (symbols_save): Use strchr. |
| 7620 | |
| 7621 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7622 | |
| 7623 | * src/print.c, src/print_graph.c (escape): New. |
| 7624 | Use it to quote the TAGS outputs. |
| 7625 | * src/print_graph.c (print_state): Now errors are in red, and |
| 7626 | reductions in green. |
| 7627 | Prefer high to wide: output the state number on a line of its own. |
| 7628 | |
| 7629 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7630 | |
| 7631 | * src/state.h, src/state.c (reductions_new): New. |
| 7632 | * src/LR0.c (set_state_table): Let all the states have a |
| 7633 | `reductions', even if reduced to 0. |
| 7634 | (save_reductions): Adjust. |
| 7635 | * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust. |
| 7636 | * src/print.c (print_reductions, print_actions): Adjust. |
| 7637 | * src/output.c (action_row): Adjust. |
| 7638 | |
| 7639 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7640 | |
| 7641 | * src/state.h, src/state.c (errs_new, errs_dup): New. |
| 7642 | * src/LR0.c (set_state_table): Let all the states have an errs, |
| 7643 | even if reduced to 0. |
| 7644 | * src/print.c (print_errs, print_reductions): Adjust. |
| 7645 | * src/output.c (output_actions, action_row): Adjust. |
| 7646 | * src/conflicts.c (resolve_sr_conflict): Adjust. |
| 7647 | |
| 7648 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7649 | |
| 7650 | * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL. |
| 7651 | |
| 7652 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7653 | |
| 7654 | * src/conflicts.c, src/conflicts.h (print_reductions): Move to... |
| 7655 | * src/print.c: here. |
| 7656 | (lookaheadset, shiftset): New, used as additional storage by |
| 7657 | print_reductions. |
| 7658 | (print_results): Adjust. |
| 7659 | (print_shifts, print_gotos, print_errs): New, extracted from... |
| 7660 | (print_actions): here. |
| 7661 | * src/print_graph.c (print_actions): Remove dead code. |
| 7662 | |
| 7663 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7664 | |
| 7665 | * src/reader.c (copy_dollar, copy_at): Better checking of `n' in |
| 7666 | `$n' and `@n'. |
| 7667 | |
| 7668 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7669 | |
| 7670 | * src/lalr.c (add_lookback_edge): Use state_t instead of ints. |
| 7671 | (build_relations): Adjust. |
| 7672 | |
| 7673 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7674 | |
| 7675 | * src/lalr.c (set_goto_map): Remove a wrong but benign loop |
| 7676 | duplication. |
| 7677 | |
| 7678 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7679 | |
| 7680 | * src/reader.c (packgram): Catch nitems overflows. |
| 7681 | |
| 7682 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7683 | |
| 7684 | * src/files.c, src/files.h (guard_obstack): Remove. |
| 7685 | * src/output.c (output): Adjust. |
| 7686 | * src/reader.c (parse_braces): New, factoring... |
| 7687 | (copy_action, copy_guard): these two which are renamed as... |
| 7688 | (parse_action, parse_guard): these. |
| 7689 | As a voluntary consequence, using braces around guards is now |
| 7690 | mandatory. |
| 7691 | |
| 7692 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7693 | |
| 7694 | * src/gram.h (rule_t): `guard' and `guard_line' are new members. |
| 7695 | * src/reader.c (symbol_list): `guard' and `guard_line' are new |
| 7696 | members. |
| 7697 | (symbol_list_new): Adjust. |
| 7698 | (copy_action): action_line is the first line, not the last. |
| 7699 | (copy_guard): Just as for actions, store the `action' only, not |
| 7700 | the switch/case/break flesh. |
| 7701 | Don't parse the user action that might follow the guard, let... |
| 7702 | (readgram): do it, i.e., now, there can be an action after a |
| 7703 | guard. |
| 7704 | In other words the guard is just explicitly optional. |
| 7705 | (packgram): Adjust. |
| 7706 | * src/output.c (guards_output): New. |
| 7707 | (output_parser): Call it when needed. |
| 7708 | (output): Also free the guard and attrs obstacks. |
| 7709 | * src/files.c, src/files.h (obstack_save): Remove. |
| 7710 | (output_files): Remove. |
| 7711 | As a result, if one needs the former `.act' file, using an |
| 7712 | appropriate skeleton which requires actions and guards is now |
| 7713 | required. |
| 7714 | * src/main.c (main): Adjust. |
| 7715 | * tests/semantic.at: New. |
| 7716 | * tests/regression.at: Use `input.y' as input file name. |
| 7717 | Avoid 8+3 problems by requiring input.c when the test needs the |
| 7718 | parser. |

| 7722 | * src/reader.c (symbol_list_new): Be sure to initialize all the |
| 7723 | fields. |
| 7724 | |
| 7725 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7726 | |
| 7727 | All the hacks using a final pseudo state are now useless. |
| 7728 | |
| 7729 | * src/LR0.c (set_state_table): state_table holds exactly nstates. |
| 7730 | * src/lalr.c (nLA): New. |
| 7731 | (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it |
| 7732 | instead of lookaheadsp from the pseudo state (nstate + 1). |
| 7733 | |
| 7734 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7735 | |
| 7736 | * src/output.c (action_row, token_actions): Use a state_t instead |
| 7737 | of a integer, and nlookaheads instead of the following state's |
| 7738 | lookaheadsp. |
| 7739 | |
| 7740 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7741 | |
| 7742 | * src/conflicts.c (log_resolution, flush_shift) |
| 7743 | (resolve_sr_conflict, set_conflicts, solve_conflicts) |
| 7744 | (count_sr_conflicts, count_rr_conflicts, conflicts_output) |
| 7745 | (conflicts_print, print_reductions): Use a state_t instead of an |
| 7746 | integer when referring to a state. |
| 7747 | As much as possible, depend upon nlookaheads, instead of the |
| 7748 | `lookaheadsp' member of the following state (since lookaheads of |
| 7749 | successive states are successive, the difference between state n + 1 |
| 7750 | and n served as the number of lookaheads for state n). |
| 7751 | * src/lalr.c (add_lookback_edge): Likewise. |
| 7752 | * src/print.c (print_core, print_actions, print_state) |
| 7753 | (print_results): Likewise. |
| 7754 | * src/print_graph.c (print_core, print_actions, print_state) |
| 7755 | (print_graph): Likewise. |
| 7756 | * src/conflicts.h: Adjust. |

| 7758 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7759 | |
| 7760 | * src/bison.hairy: Formatting/comment changes. |
| 7761 | ANSIfy. |
| 7762 | Remove `register' indications. |
| 7763 | Add plenty of `static'. |
| 7764 | |
| 7765 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 7766 | |
| 7767 | * src/output.c (prepare): Drop the muscle `ntbase' which |
| 7768 | duplicates ntokens. |
| 7769 | * src/bison.simple: Formatting/comment changes. |
| 7770 | Use YYNTOKENS only, which is documented, but not YYNTBASE, which |
| 7771 | is an undocumented synonym. |
| 7772 | |
| 7773 | 2001-12-22 Akim Demaille <akim@epita.fr> |
| 7774 | |
| 7775 | * src/output.c (output_table_data): Change the prototype to use |
| 7776 | `int' for array ranges: some invocations do pass an int, not a |
| 7777 | short. |
| 7778 | Reported by Wayne Green. |
| 7779 | |
| 7780 | 2001-12-22 Akim Demaille <akim@epita.fr> |

| 7782 | Some actions of web2c.y are improperly triggered. |
| 7783 | Reported by Mike Castle. |
| 7784 | |
| 7785 | * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/. |

| 7787 | (Web2c Report): this. |
| 7788 | (Web2c Actions): New. |
| 7789 | |
| 7790 | 2001-12-22 Akim Demaille <akim@epita.fr> |
| 7791 | |
| 7792 | Reductions in web2c.y are improperly reported. |
| 7793 | Reported by Mike Castle. |
| 7794 | |
| 7795 | * src/conflicts.c (print_reductions): Fix. |
| 7796 | * tests/regression.at (Web2c): New. |
| 7797 | |
| 7798 | 2001-12-18 Akim Demaille <akim@epita.fr> |
| 7799 | |
| 7800 | Some host fail on `assert (!"foo")', which expands to |
| 7801 | ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__)) |
| 7802 | Reported by Nelson Beebee. |
| 7803 | |
| 7804 | * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with |
| 7805 | `#define it_succeeded 0' and `assert (it_succeeded)'. |
| 7806 | |
| 7807 | 2001-12-17 Marc Autret <autret_m@epita.fr> |
| 7808 | |
| 7809 | * src/bison.simple: Don't hard code the skeleton line and filename. |
| 7810 | * src/output.c (output_parser): Rename 'line' as 'output_line'. |
| 7811 | New line counter 'skeleton_line' (skeleton-line muscle). |
| 7812 | |
| 7813 | 2001-12-17 Paul Eggert <eggert@twinsun.com> |
| 7814 | |
| 7815 | * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that |
| 7816 | YYDEBUG must be defined to a nonzero value. |
| 7817 | |
| 7818 | * src/bison.simple (yytname): Do not assume that the user defines |
| 7819 | YYDEBUG to a properly parenthesized expression. |
| 7820 | |
| 7821 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 7822 | |
| 7823 | * src/state.h (state_t): Rename lookaheads as lookaheadsp. |
| 7824 | nlookaheads is a new member. |
| 7825 | Adjust all users. |
| 7826 | * src/lalr.h (nlookaheads): Remove this orphan declaration. |
| 7827 | * src/lalr.c (initialize_lookaheads): Set nlookaheads for each |
| 7828 | state. |
| 7829 | |
| 7830 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 7831 | |
| 7832 | * src/files.h, src/files.c (open_files, close_files): Remove. |
| 7833 | * src/main.c (main): Don't open/close files, nor invoke lex_free, |
| 7834 | let... |
| 7835 | * src/reader.c (reader): Do it. |

| 7837 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 7838 | |

| 7840 | |
| 7841 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 7842 | |
| 7843 | * src/conflicts.c (flush_shift): Also adjust lookaheadset. |
| 7844 | (flush_reduce): New. |
| 7845 | (resolve_sr_conflict): Adjust. |
| 7846 | |
| 7847 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 7848 | |
| 7849 | * src/output.c (output_obstack): Be static and rename as... |
| 7850 | (format_obstack): this, to avoid any confusion with files.c's |
| 7851 | output_obstack. |
| 7852 | * src/reader.h (muscle_obstack): Move to... |
| 7853 | * src/output.h: here, since it's defined in output.c. |
| 7854 | |
| 7855 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 7856 | |
| 7857 | * src/output.c (action_row, save_column, default_goto) |
| 7858 | (sort_actions, matching_state, pack_vector): Better variable |
| 7859 | locality. |

| 7863 | * src/output.c: Various formatting changes. |
| 7864 | |
| 7865 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 7866 | |
| 7867 | * src/files.c (output_files): Free the output_obstack. |
| 7868 | * src/main.c (main): Call print and print_graph conditionally. |
| 7869 | * src/print.c (print): Work unconditionally. |
| 7870 | * src/print_graph.c (print_graph): Work unconditionally. |
| 7871 | * src/conflicts.c (log_resolution): Output only if verbose_flag. |
| 7872 | |
| 7873 | 2001-12-16 Marc Autret <autret_m@epita.fr> |
| 7874 | |
| 7875 | * src/output.c (actions_output): Fix. When we use %no-lines, |
| 7876 | there is one less line per action. |
| 7877 | |
| 7878 | 2001-12-16 Marc Autret <autret_m@epita.fr> |
| 7879 | |
| 7880 | * src/bison.simple: Remove a useless #line directive. |
| 7881 | s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'. |
| 7882 | * src/output.c (get_lines_number): New. |
| 7883 | (output_parser): Adjust, now takes care about the lines of a |
| 7884 | output muscles. |
| 7885 | Fix line numbering. |
| 7886 | (actions_output): Computes the number of lines taken by actions. |
| 7887 | (output_master_parser): Insert new skeleton which is the name of |
| 7888 | the output parser file name. |
| 7889 | |
| 7890 | 2001-12-15 Marc Autret <autret_m@epita.fr> |
| 7891 | |
| 7892 | * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility. |
| 7893 | |
| 7894 | 2001-12-15 Marc Autret <autret_m@epita.fr> |
| 7895 | |
| 7896 | * src/output.c (output_gram): Keep track of the hairy one. |
| 7897 | |
| 7898 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 7899 | |
| 7900 | Make `make distcheck' work. |
| 7901 | |
| 7902 | * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses |
| 7903 | system.h which uses libgettext.h. |
| 7904 | |
| 7905 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 7906 | |
| 7907 | * src/nullable.c (set_nullable): Useless rules must be skipped, |
| 7908 | otherwise, since we range over their symbols, we might look at a |
| 7909 | nonterminal which no longer ``exists'', i.e., it is not counted in |
| 7910 | `nvars', hence we overflow our arrays. |
| 7911 | |
| 7912 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 7913 | |
| 7914 | The header can also be produced directly, without any obstack! |
| 7915 | Yahoo! |
| 7916 | |
| 7917 | * src/files.c, src/files.h (defines_obstack): Remove. |
| 7918 | (compute_header_macro): Global. |
| 7919 | (defines_obstack_save): Remove. |
| 7920 | * src/reader.c (parse_union_decl): No longer output to |
| 7921 | defines_obstack: its content can be found in the `stype' muscle |
| 7922 | anyway. |
| 7923 | (output_token_translations): Merge into... |
| 7924 | (symbols_output): this. |
| 7925 | Rename as... |
| 7926 | (symbols_save): this. |
| 7927 | (reader): Adjust. |
| 7928 | * src/output.c (header_output): New. |
| 7929 | (output): Call it. |
| 7930 | |
| 7931 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 7932 | |
| 7933 | * src/reader.c (parse_union_decl): Instead of handling two obstack |
| 7934 | simultaneously, use one to define the `stype' muscle, and use the |
| 7935 | value of the latter to fill defines_obstack. |
| 7936 | (copy_comment): Remove. |
| 7937 | (copy_comment2): Work for a single obstack. |
| 7938 | Rename as... |
| 7939 | (copy_comment): this. |
| 7940 | |
| 7941 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 7942 | |
| 7943 | * src/lex.c, src/lex.h (xgetc): No longer static. |
| 7944 | * src/reader.c (parse_union_decl): Revamp. |
| 7945 | |
| 7946 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 7947 | |
| 7948 | Still making progress in separating Bison into (i) input, (ii) |
| 7949 | process, (iii) output: now we can directly output the parser file |
| 7950 | without using table_obstack at all. |
| 7951 | |
| 7952 | * src/files.c, src/files.h (table_obstack): Bye bye. |
| 7953 | (parser_file_name): New. |
| 7954 | * src/files.c (compute_output_file_names): Compute it. |
| 7955 | * src/output.c (actions_output, output_parser) |
| 7956 | (output_master_parser): To a file instead of an obstack. |
| 7957 | |
| 7958 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 7959 | |
| 7960 | Attach actions to rules, instead of pre-outputting them to |
| 7961 | actions_obstack. |
| 7962 | |
| 7963 | * src/gram.h (rule_t): action and action_line are new members. |
| 7964 | * src/reader.c (symbol_list): Likewise. |
| 7965 | (copy_action): Save the actions within the rule. |
| 7966 | (packgram): Save them in rule_table. |
| 7967 | * src/output.c (actions_output): New. |
| 7968 | (output_parser): Use it on `%%actions'. |
| 7969 | (output_rule_data): Don't free rule_table. |
| 7970 | (output): Do it. |
| 7971 | (prepare): Don't save the `action' muscle. |
| 7972 | * src/bison.simple: s/%%action/%%actions/. |
| 7973 | |
| 7974 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 7975 | |
| 7976 | * src/reader.c (copy_action): When --yacc, don't append a `;' |
| 7977 | to the user action: let it fail if lacking. |
| 7978 | Suggested by Arnold Robbins and Tom Tromey. |
| 7979 | |
| 7980 | 2001-12-14 Akim Demaille <akim@epita.fr> |
| 7981 | |
| 7982 | * src/lex.c (literalchar): Simply return the char you decoded, non |
| 7983 | longer mess around with obstacks and int pointers. |
| 7984 | Adjust all callers. |
| 7985 | |
| 7986 | 2001-12-14 Akim Demaille <akim@epita.fr> |
| 7987 | |
| 7988 | * src/lex.c (literalchar): Don't escape the special characters, |
| 7989 | just decode them, and keep them as char (before, eol was output as |
| 7990 | the 2 char string `\n' etc.). |
| 7991 | * src/output.c (output_rule_data): Use quotearg to output the |
| 7992 | token strings. |
| 7993 | |
| 7994 | 2001-12-13 Paul Eggert <eggert@twinsun.com> |
| 7995 | |
| 7996 | * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE): |
| 7997 | Do not infringe on the global user namespace when using C++. |
| 7998 | (YYFPRINTF, YYSTDERR): New macros, needed for the above. |
| 7999 | All uses of `fprintf' and `stderr' changed. |
| 8000 | |
| 8001 | * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR. |
| 8002 | |
| 8003 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 8004 | |
| 8005 | The computation of nullable is broken: it doesn't handle empty |
| 8006 | RHS's properly. |
| 8007 | |
| 8008 | * tests/torture.at (GNU AWK Grammar): New. |
| 8009 | * tests/sets.at (Nullable): New. |
| 8010 | * src/nullable.c (set_nullable): Instead of blindly looping over |
| 8011 | `ritems', loop over the rules, and then over their rhs's. |
| 8012 | |
| 8013 | Work around Autotest bugs. |
| 8014 | |
| 8015 | * src/warshall.c (bitmatrix_print): Don't use `+--+' as table |
| 8016 | frame, because Autotest understand lines starting with a `+' as |
| 8017 | traces from the shell. Then, they are not processed properly. |
| 8018 | Admittedly an Autotest bug, but we don't have time to wait for |
| 8019 | Autotest to catch up. |
| 8020 | * tests/regression.at (Broken Closure): Adjust to the new table |
| 8021 | frames. |
| 8022 | Move to... |
| 8023 | * tests/sets.at: here. |
| 8024 | |
| 8025 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 8026 | |
| 8027 | * src/closure.c (closure): Use nrules instead of playing tricks |
| 8028 | with BITS_PER_WORD. |
| 8029 | |
| 8030 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 8031 | |
| 8032 | * src/print.c (print_actions): Output the handling of `$' as the |
| 8033 | traces do: shifting the token EOF. Before EOF was treated as a |
| 8034 | nonterminal. |
| 8035 | * tests/regression.at: Adjust some tests. |
| 8036 | * src/print_graph.c (print_core): Complete the set of items via |
| 8037 | closure. The next-to-final and final states are still unsatisfying, |
| 8038 | but that's to be addressed elsewhere. |
| 8039 | No longer output the rule numbers, but do output the state number. |
| 8040 | A single loop for the shifts + gotos is enough, but picked a |
| 8041 | distinct color for each. |
| 8042 | (print_graph): Initialize and finalize closure. |
| 8043 | |
| 8044 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 8045 | |
| 8046 | * src/reader.c (readgram): Remove dead code, an strip useless |
| 8047 | braces. |
| 8048 | (get_type): Remove, unused. |
| 8049 | |
| 8050 | 2001-12-12 Akim Demaille <akim@epita.fr> |
| 8051 | |
| 8052 | * src/complain.h, src/complain.c: Remove error_one_per_line, rely |
| 8053 | on that of lib/error.c. |
| 8054 | |
| 8055 | 2001-12-12 Akim Demaille <akim@epita.fr> |
| 8056 | |
| 8057 | Some hosts don't like `/' in includes. |
| 8058 | |
| 8059 | * src/system.h: Include libgettext.h without qualifying the path. |
| 8060 | * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove |
| 8061 | $(top_srcdir). |
| 8062 | |
| 8063 | 2001-12-11 Marc Autret <autret_m@epita.fr> |
| 8064 | |
| 8065 | * src/output.c (output_parser): Remove useless muscle. |
| 8066 | |
| 8067 | 2001-12-11 Marc Autret <autret_m@epita.fr> |
| 8068 | |
| 8069 | * src/bison.simple: Remove #line just before %%epilogue. It |
| 8070 | is now handled in ... |
| 8071 | * src/reader.c (read_additionnal_code): Add the output of a |
| 8072 | #line for the epilogue. |
| 8073 | |
| 8074 | 2001-12-10 Marc Autret <autret_m@epita.fr> |
| 8075 | |
| 8076 | * src/reader.c (copy_definition): Re-use CPP-outed code which |
| 8077 | replace precedent remove. |
| 8078 | * src/bison.simple: Remove #line before %%prologue because |
| 8079 | %%input-line is wrong at this time. |
| 8080 | |
| 8081 | 2001-12-10 Marc Autret <autret_m@epita.fr> |
| 8082 | |
| 8083 | * src/reader.c (symbols_output): Clean up. |
| 8084 | * src/output.c (output_gram, output): Clean up. |
| 8085 | |
| 8086 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8087 | |
| 8088 | * src/lalr.c (initialize_lookaheads): New. Extracted from... |
| 8089 | * src/LR0.c (set_state_table): here. |
| 8090 | * src/lalr.c (lalr): Call it. |
| 8091 | |
| 8092 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8093 | |
| 8094 | * src/state.h (shifts): Remove the `number' member: shifts are |
| 8095 | attached to state, hence no longer need to be labelled with a |
| 8096 | state number. |
| 8097 | |
| 8098 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8099 | |
| 8100 | Now that states have a complete set of members, the linked list of |
| 8101 | shifts is useless: just fill directly the state's shifts member. |
| 8102 | |
| 8103 | * src/state.h (shifts): Remove the `next' member. |
| 8104 | * src/LR0.c (first_state, last_state): Remove. |
| 8105 | Adjust the callers. |
| 8106 | (augment_automaton): Don't look for the shifts that must be added |
| 8107 | a shift on EOF: it is those of the state we looked for! But now, |
| 8108 | since shifts are attached, it is no longer needed to looking |
| 8109 | merely by its id: its number. |
| 8110 | |
| 8111 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8112 | |
| 8113 | * src/LR0.c (augment_automaton): Better variable locality. |
| 8114 | Remove an impossible branch: if there is a state corresponding to |
| 8115 | the start symbol being shifted, then there is shift for the start |
| 8116 | symbol from the initial state. |
| 8117 | |
| 8118 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8119 | |
| 8120 | * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state' |
| 8121 | only when appropriate: when insert_start_shifting_state' is not |
| 8122 | invoked. |
| 8123 | * tests/regression.at (Rule Line Numbers): Adjust. |
| 8124 | |
| 8125 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8126 | |
| 8127 | * src/LR0.c (augment_automaton): Now that all states have shifts, |
| 8128 | merge the two cases addition shifts to the initial state. |
| 8129 | |
| 8130 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8131 | |
| 8132 | * src/lalr.c (set_state_table): Move to... |
| 8133 | * src/LR0.c: here. |
| 8134 | * src/lalr.c (lalr): Don't call it... |
| 8135 | * src/LR0.c (generate_states): do it. |
| 8136 | * src/LR0.h (first_state): Remove, only the table is used. |
| 8137 | |
| 8138 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8139 | |
| 8140 | * src/LR0.h (first_shift, first_reduction): Remove. |
| 8141 | * src/lalr.c: Don't use first_shift: find shifts through the |
| 8142 | states. |
| 8143 | |
| 8144 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8145 | |
| 8146 | * src/LR0.c: Attach shifts to states as soon as they are |
| 8147 | computed. |
| 8148 | * src/lalr.c (set_state_table): Instead of assigning shifts to |
| 8149 | state, just assert that the mapping was properly done. |
| 8150 | |
| 8151 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8152 | |
| 8153 | * src/LR0.c (insert_start_shift): Rename as... |
| 8154 | (insert_start_shifting_state): this. |
| 8155 | (insert_eof_shifting_state, insert_accepting_state): New. |
| 8156 | (augment_automaton): Adjust. |
| 8157 | Better locality of the variables. |
| 8158 | When looking if the start_symbol is shifted from the initial |
| 8159 | state, using `while (... symbol != start_symbol ...)' sounds |
| 8160 | better than `while (... symbol < start_symbol ...)': If fail |
| 8161 | to see how the order between symbols could be relevant! |
| 8162 | |
| 8163 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8164 | |
| 8165 | * src/getargs.h: Don't declare `spec_name_prefix' and |
| 8166 | `spec_file_prefix', declared by src/files.h. |
| 8167 | * src/files.c, src/files.h: Default for spec_name_prefix is "yy". |
| 8168 | * src/muscle_tab.c (muscle_init): Default prefix to NULL. |
| 8169 | * src/output.c (prepare): Adjust. |
| 8170 | * src/reader.c (symbols_output): Likewise. |
| 8171 | * src/vmsgetargs.c: Vaguely adjust, but who cares? |
| 8172 | |
| 8173 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8174 | |
| 8175 | * src/muscle_tab.c (muscle_init): NULL is a better default than |
| 8176 | `"0"'. |
| 8177 | |
| 8178 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8179 | |
| 8180 | * src/reader.c (reader): Calling symbols_output once is enough. |
| 8181 | |
| 8182 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8183 | |
| 8184 | Now that states have a complete set of members, the linked list of |
| 8185 | reductions is useless: just fill directly the state's reductions |
| 8186 | member. |
| 8187 | |
| 8188 | * src/state.h (struct reductions): Remove member `number' and |
| 8189 | `next'. |
| 8190 | * src/LR0.c (first_reduction, last_reduction): Remove. |
| 8191 | (save_reductions): Don't link the new reductions, store them in |
| 8192 | this_state. |
| 8193 | * src/lalr.c (set_state_table): No need to attach reductions to |
| 8194 | states, it's already done. |
| 8195 | * src/output.c (output_actions): No longer free the shifts, then |
| 8196 | the reductions, then the states: free all the states and their |
| 8197 | members. |
| 8198 | |
| 8199 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8200 | |
| 8201 | * src/options.c (OPTN, DRTV, BOTH): New. |
| 8202 | (option_table): Use them. |
| 8203 | |
| 8204 | * src/muscle_tab.c: Don't include xalloc.h and string.h: that's |
| 8205 | the job of system.h. |
| 8206 | * src/options.c: Don't include stdio.h and xalloc.h for the same |
| 8207 | reasons. |
| 8208 | |
| 8209 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8210 | |
| 8211 | * src/output.c (output, prepare): Make sure the values of the |
| 8212 | muscles `action' and `prologue' are 0-terminated. |
| 8213 | |
| 8214 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8215 | |
| 8216 | Clean up GCC warnings. |
| 8217 | |
| 8218 | * src/reader.c (copy_action): `buf' is not used. |
| 8219 | (parse_skel_decl): Be static. |
| 8220 | * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'. |
| 8221 | * src/options.h (create_long_option_table): Have a real prototype. |
| 8222 | * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete) |
| 8223 | (hash_delete_at): Return const void *. |
| 8224 | Adjust casts to preserve the const. |
| 8225 | |
| 8226 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8227 | |
| 8228 | * configure.in: Require 2.52g. |
| 8229 | M4 is not needed, but AUTOM4TE is. |
| 8230 | * m4/m4.m4: Remove. |
| 8231 | * tests/Makefile.am: Adjust. |
| 8232 | |
| 8233 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8234 | |
| 8235 | One structure for states is enough, even though theoretically |
| 8236 | there are LR(0) states and LALR(1) states. |
| 8237 | |
| 8238 | * src/lalr.h (state_t): Remove. |
| 8239 | (state_table): Be state_t **, not state_t *. |
| 8240 | * src/state.h (core, CORE_ALLOC): Rename as... |
| 8241 | (state_t, STATE_ALLOC): this. |
| 8242 | Add the LALR(1) members: shifts, reductions, errs. |
| 8243 | * src/LR0.c (state_table): Rename as... |
| 8244 | (state_hash): this, to avoid name clashes with the global |
| 8245 | `state_table'. |
| 8246 | * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c |
| 8247 | * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust. |
| 8248 | |
| 8249 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 8250 | |
| 8251 | Bison dumps core on bash.y. |
| 8252 | Reported by Pascal Bart. |
| 8253 | |
| 8254 | * src/warshall.c (bitmatrix_print): New. |
| 8255 | (TC): Use it. |
| 8256 | When performing a transitive closure R(i, j) && R(j, k) => R(i, k), |
| 8257 | j must be the outer loop. |
| 8258 | * tests/regression.at (Broken Closure): New. |
| 8259 | |
| 8260 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8261 | |
| 8262 | * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and |
| 8263 | its argument. |
| 8264 | Reported by Peter Hamorsky. |
| 8265 | |
| 8266 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8267 | |
| 8268 | * src/conflicts.c (err_table): Remove. |
| 8269 | (resolve_sr_conflict): Adjust. |
| 8270 | * src/lalr.h (state_t.reduction_table, state_t.shift_table): |
| 8271 | Rename as... |
| 8272 | (state_t.reductions, state_t.shifts): this. |
| 8273 | |
| 8274 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8275 | |
| 8276 | * src/reduce.c (reduce_grammar_tables): No longer disable the |
| 8277 | removal of useless rules via CPP but via `if (0)', so that the |
| 8278 | compiler still check the code is valid. |
| 8279 | For instance, it should have noticed `rline' no longer exists: use |
| 8280 | the `line' member of rule_t. |
| 8281 | * src/gram.c (dummy, rline): Remove, unused. |
| 8282 | |
| 8283 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8284 | |
| 8285 | * src/output.c (pack_vector): Use assert, not berror. |
| 8286 | * src/main.c (berror): Remove, unused. |
| 8287 | |
| 8288 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8289 | |
| 8290 | New experimental feature: if --verbose --trace output all the |
| 8291 | items of a state, not only its kernel. |
| 8292 | |
| 8293 | * src/print.c (print_core): If `trace_flag', then invoke closure |
| 8294 | before outputting the items of the state (print_core is no longer |
| 8295 | a correct name them). |
| 8296 | (print_results): Invoke new_closure/free_closure if needed. |
| 8297 | |
| 8298 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8299 | |
| 8300 | * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount. |
| 8301 | * src/closure.c, src/closure.h (itemsetsize): Rename as... |
| 8302 | (nitemset): for consistency with the rest of the project. |
| 8303 | |
| 8304 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8305 | |
| 8306 | * src/closure.c (print_closure): Improve. |
| 8307 | (closure): Use it for printing input and output. |
| 8308 | |
| 8309 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8310 | |
| 8311 | * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are |
| 8312 | indexed by nonterminals. |
| 8313 | |
| 8314 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8315 | |
| 8316 | * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of |
| 8317 | what it was!). |
| 8318 | * src/warshall.h: Remove accidental duplication of the content. |
| 8319 | |
| 8320 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8321 | |
| 8322 | * src/closure.c (set_fderives): De-obfuscate. |
| 8323 | |
| 8324 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8325 | |
| 8326 | * src/closure.c (print_firsts, print_fderives): De-obfuscate. |
| 8327 | |
| 8328 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8329 | |
| 8330 | * src/closure.c (set_firsts): De-obfuscate. |
| 8331 | |
| 8332 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8333 | |
| 8334 | * src/output.c (action_row): De-obfuscate |
| 8335 | using the good o' techniques: arrays not pointers, variable |
| 8336 | locality, BITISSET, RESETBIT etc. |
| 8337 | |
| 8338 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8339 | |
| 8340 | Pessimize the code to simplify it: from now on, all the states |
| 8341 | have a valid SHIFTS, which NSHIFTS is possibly 0. |
| 8342 | |
| 8343 | * src/LR0.c (shifts_new): Be global and move to.. |
| 8344 | * src/state.c, src/state.h: here. |
| 8345 | * src/conflicts, src/lalr.c, src/output.c, src/print.c, |
| 8346 | * src/print_graph: Adjust. |
| 8347 | |
| 8348 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8349 | |
| 8350 | * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New. |
| 8351 | * src/conflicts.c: Use it. |
| 8352 | Restore a few missing `if (!SHIFT_IS_DISABLED)' which were |
| 8353 | incorrectly ``simplified''. |
| 8354 | |
| 8355 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8356 | |
| 8357 | * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate |
| 8358 | using the good o' techniques: arrays not pointers, variable |
| 8359 | locality, BITISSET, RESETBIT etc. |
| 8360 | |
| 8361 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8362 | |
| 8363 | * src/state.h (SHIFT_SYMBOL): New. |
| 8364 | * src/conflicts.c: Use it to deobfuscate. |
| 8365 | |
| 8366 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8367 | |
| 8368 | * src/conflicts.c (count_sr_conflicts, count_rr_conflicts) |
| 8369 | (print_reductions): De-obfuscate using the good o' techniques: |
| 8370 | arrays not pointers, variable locality, BITISSET. |
| 8371 | |
| 8372 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8373 | |
| 8374 | * src/conflicts.c (print_reductions): Arrays, not pointers. |
| 8375 | Use BITISSET. |
| 8376 | |
| 8377 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8378 | |
| 8379 | * src/conflicts.c (print_reductions): Pessimize, but clarify. |
| 8380 | |
| 8381 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8382 | |
| 8383 | * src/conflicts.c (print_reductions): Improve variable locality. |
| 8384 | |
| 8385 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8386 | |
| 8387 | * src/conflicts.c (print_reductions): Pessimize, but clarify. |
| 8388 | |
| 8389 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8390 | |
| 8391 | * src/conflicts.c (print_reductions): Improve variable locality. |
| 8392 | |
| 8393 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8394 | |
| 8395 | * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New. |
| 8396 | * src/lalr.c: Use them. |
| 8397 | |
| 8398 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8399 | |
| 8400 | * src/LR0.c (augment_automaton): Formatting changes. |
| 8401 | Better variable locality. |
| 8402 | |
| 8403 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8404 | |
| 8405 | * src/lalr.c (matrix_print): New. |
| 8406 | (transpose): Use it. |
| 8407 | Use arrays instead of pointers. |
| 8408 | |
| 8409 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8410 | |
| 8411 | * src/lalr.c (maxrhs): Move to... |
| 8412 | * src/gram.c, src/gram.h (ritem_longest_rhs): here. |
| 8413 | * src/lalr.c (build_relations): Adjust. |
| 8414 | |
| 8415 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8416 | |
| 8417 | * src/lalr.c (transpose): Free the memory allocated to the |
| 8418 | argument, as it is replaced by the results by the unique caller. |
| 8419 | (build_relations): Merely invoke transpose: it handles the memory |
| 8420 | deallocation. |
| 8421 | Improve variable locality. |
| 8422 | Avoid variables used as mere abbreviations. |
| 8423 | (compute_lookaheads): Use arrays instead of pointers. |
| 8424 | |
| 8425 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8426 | |
| 8427 | * src/lalr.c (initialize_F): Improve variable locality. |
| 8428 | Avoid variables used as mere abbreviations. |
| 8429 | |
| 8430 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8431 | |
| 8432 | * src/derives.c (print_derives): Display the ruleno. |
| 8433 | * src/lalr.c (initialize_F, transpose): Better variable locality |
| 8434 | to improve readability. |
| 8435 | Avoid variables used as mere abbreviations. |
| 8436 | |
| 8437 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8438 | |
| 8439 | * src/lalr.c (traverse): Use arrays instead of pointers. |
| 8440 | |
| 8441 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8442 | |
| 8443 | * src/nullable.c (set_nullable): Use a for loop to de-obfuscate |
| 8444 | the handling of squeue. |
| 8445 | `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'. |
| 8446 | |
| 8447 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8448 | |
| 8449 | Because useless nonterminals are now kept alive (instead of being |
| 8450 | `destroyed'), we now sometimes examine them, and store information |
| 8451 | related to them. Hence we need to know their number, and adjust |
| 8452 | memory allocations. |
| 8453 | |
| 8454 | * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer |
| 8455 | static. |
| 8456 | * src/LR0.c (allocate_itemsets): The memory allocated to |
| 8457 | `symbol_count' was used for two different purpose: once to count |
| 8458 | the number of occurrences of each symbol, and later reassigned to |
| 8459 | `shift_symbol', containing the symbol that can be shifted from a |
| 8460 | given state. |
| 8461 | Deobfuscate, i.e., allocate, use and free `symbol_count' here |
| 8462 | only, and... |
| 8463 | (new_itemsets): Allocate `shift_symbol' here. |
| 8464 | (allocate_itemsets): symbol_count includes useless nonterminals. |
| 8465 | Make room for them. |
| 8466 | (free_storage): Use `free', not `XFREE', for pointers that cannot |
| 8467 | be null. |
| 8468 | |
| 8469 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8470 | |
| 8471 | * src/nullable.c (set_nullable): Deobfuscate the handling of |
| 8472 | ritem. |
| 8473 | `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'. |
| 8474 | |
| 8475 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 8476 | |
| 8477 | * src/gram.c, src/gram.h (ritem_print): New. |
| 8478 | * src/gram.c (dummy): Remove, now there is actual code in gram.c. |
| 8479 | (This useless function was defined only to work around VMS linkers |
| 8480 | that can't handle compilation units with variables only). |
| 8481 | * src/reduce.c (dump_grammar): Use it to trace the construction of |
| 8482 | ritem. |
| 8483 | |
| 8484 | 2001-12-04 Paul Eggert <eggert@twinsun.com> |
| 8485 | |
| 8486 | * src/bison.simple (union yyalloc): Change member names |
| 8487 | to be the same as the stack names. |
| 8488 | (yyparse): yyptr is now union yyalloc *, not char *. |
| 8489 | (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning, |
| 8490 | and may generate better code on some machines. |
| 8491 | (yystpcpy): Use prototype if __STDC__ is defined, not just |
| 8492 | if __cplusplus is defined. |
| 8493 | |
| 8494 | 2001-11-30 Akim Demaille <akim@epita.fr> |
| 8495 | |
| 8496 | * configure.in (WARNING_CFLAGS): Add -Werror when possible. |
| 8497 | (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU |
| 8498 | Gettext doesn't compile cleanly, and dies with -Werror. |

| 8510 | (quotearg_n_options): Abort if N is negative. |
| 8511 | Avoid overflow check on hosts where size_t is 64 bits and int |
| 8512 | is 32 bits, as overflow is impossible there. |
| 8513 | Fix off-by-one typo that caused unnecessary reallocation. |
| 8514 | |
| 8515 | 2001-11-29 Paul Eggert <eggert@twinsun.com> |

| 8528 | on user names when possible. |

| 8607 | (__yy_memcpy): Last arg is size_t, not unsigned int, to remove |
| 8608 | an arbitrary restriction on hosts where size_t is wider than int. |
| 8609 | |
| 8610 | (yyparse): Don't dump core if alloca or malloc fails; instead, report |
| 8611 | a parser stack overflow. Allocate just one block of memory for all |
| 8612 | three stacks, instead of allocating three blocks; this typically is |
| 8613 | faster and reduces fragmentation. |
| 8614 | |
| 8615 | Do not limit the number of items in the stack to a value that fits |
| 8616 | in 'int', as this is an arbitrary limit on hosts with 64-bit |
| 8617 | size_t and 32-bit int. |

| 9045 | * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g: |

| 9074 | arg_offset. |

| 10445 | |
| 10446 | * src/lex.c (token_obstack): New. |
| 10447 | (init_lex): Initialize it. No longer call... |

| 10475 | * src/reader.c (read_declarations): Adjust. |
| 10476 | * src/files.c (open_files): Don't call `compute_base_names', don't |

| 10478 | *in* the input file now. |
| 10479 | (output_files): Do it here. |
| 10480 | * src/output.c (output_headers): Document the fact that this patch |

| 10812 | When a literal string is used to define two different tokens, |
| 10813 | `bison -v' segfaults. |
| 10814 | Reported by Piotr Gackiewicz, and fixed by Neil Booth. |
| 10815 | |
| 10816 | * tests/regression.m4: New file. |
| 10817 | Include the core of the sample provided by Piotr Gackiewicz. |
| 10818 | * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed |
| 10819 | properly. |

| 10828 | |
| 10829 | * bison.s1 (yyparse): Assign the default value |
| 10830 | unconditionally, to avoid a GCC warning and make the parser a |
| 10831 | tad smaller. |
| 10832 | |
| 10833 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 10834 | |
| 10835 | * src/getargs.c (getargs): Don't dump `--help' on unrecognized |
| 10836 | options. |
| 10837 | |
| 10838 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 10839 | |
| 10840 | * src/derives.c, src/print.c, src/reduce.c: To ease the |
| 10841 | translation, move some `\n' out of the translated strings. |
| 10842 | |

| 10845 | The location tracking mechanism is precious for parse error |
| 10846 | messages. Nevertheless, it is enabled only when `@n' is used in |
| 10847 | the grammar, which is a different issue (you can use it in error |
| 10848 | message, but not in the grammar per se). Therefore, there should |
| 10849 | be another means to enable it. |
| 10850 | |
| 10851 | * src/getargs.c (getargs): Support `--locations'. |
| 10852 | (usage): Report it. |
| 10853 | * src/getargs.h (locationsflag): Export it. |
| 10854 | * src/lex.c (percent_table): Support `%locations'. |
| 10855 | * src/reader.c (yylsp_needed): Remove this variable, now replaced |
| 10856 | with `locationsflag'. |
| 10857 | * doc/bison.texinfo: Document `--locations' and `%locations'. |
| 10858 | Sort the options. |
| 10859 | * tests/calc.m4: Test it. |
| 10860 | |
| 10861 | For regularity of the names, replace each |
| 10862 | (nolineflag, toknumflag, rawtokenumflag, noparserflag): with... |
| 10863 | (no_lineflag, token_tableflag, rawflag, no_parserflag): this. |
| 10864 | In addition replace each `flag' with `_flag'. |
| 10865 | |
| 10866 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 10867 | |
| 10868 | Also test parse error messages, including with YYERROR_VERBOSE. |
| 10869 | |
| 10870 | * tests/calc.m4 (calc.y): Add support for `exp = exp' (non |
| 10871 | associative). |
| 10872 | Use it to check the computations. |
| 10873 | Use it to check `nonassoc' is honored. |
| 10874 | (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed |
| 10875 | `--yyerror-verbose'. |
| 10876 | (_AT_CHECK_CALC): Adjust to this option. |
| 10877 | (_AT_CHECK_CALC_ERROR): New macro to check parse error messages. |
| 10878 | |
| 10879 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 10880 | |
| 10881 | Test also `--verbose', `--defines' and `--name-prefix'. Testing |
| 10882 | the latter demonstrates a flaw in the handling of non debugging |
| 10883 | parsers introduced by myself on 2000-03-16: `#define yydebug 0' |
| 10884 | was used in order to simplify: |
| 10885 | |
| 10886 | #if YYDEBUG |
| 10887 | if (yydebug) |
| 10888 | { |
| 10889 | ... |
| 10890 | } |
| 10891 | #endif |
| 10892 | |
| 10893 | into |
| 10894 | |
| 10895 | if (yydebug) |
| 10896 | { |
| 10897 | ... |
| 10898 | } |
| 10899 | |
| 10900 | unfortunately this leads to a CPP conflict when |
| 10901 | `--name-prefix=foo' is used since it produces `#define yydebug |
| 10902 | foodebug'. |
| 10903 | |
| 10904 | * src/bison.s1 [!YYDEBUG]: Do not define yydebug. |
| 10905 | (YYDPRINTF): New macro. |
| 10906 | Spread its use. |
| 10907 | * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from |
| 10908 | the bison options. |
| 10909 | Also test `--verbose', `--defines' and `--name-prefix'. |
| 10910 | |
| 10911 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 10912 | |
| 10913 | Improve the readability of the produced parsers. |
| 10914 | |
| 10915 | * src/bison.s1: Formatting changes. |
| 10916 | Improve the comment related to the `$' mark. |
| 10917 | (yydefault): Don't fall through to `yyresume': `goto' there. |
| 10918 | * src/output.c (output_parser): When the `$' is met, skip the end |
| 10919 | of its line. |
| 10920 | New variable, `number_of_dollar_signs', to check there's exactly |
| 10921 | one `$' in the parser skeleton. |
| 10922 | |
| 10923 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 10924 | |
| 10925 | * lib/xstrdup.c: New file, from the fileutils. |
| 10926 | * src/reader.c (parse_token_decl, get_type_name, parse_type_decl) |
| 10927 | (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup' |
| 10928 | instead of strlen + xmalloc + strcpy. |
| 10929 | * src/symtab.c (copys): Remove, use xstrdup instead. |
| 10930 | |
| 10931 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 10932 | |
| 10933 | * src/gram.h (associativity): New enum type which replaces the |
| 10934 | former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with |
| 10935 | `right_assoc', `left_assoc' and `non_assoc'. |
| 10936 | Adjust all dependencies. |
| 10937 | * src/reader.c: Formatting changes. |
| 10938 | (LTYPESTR): Don't define it, use it as a literal in |
| 10939 | `reader_output_yylsp'. |
| 10940 | * src/symtab.h (symbol_class): New enum type which replaces the |
| 10941 | former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with |
| 10942 | `sunknown', `stoken and `snterm'. |
| 10943 | |
| 10944 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 10945 | |
| 10946 | * src/getargs.c (fixed_outfiles): Rename as... |
| 10947 | (yaccflag): for consistency and accuracy. |
| 10948 | Adjust dependencies. |
| 10949 | |
| 10950 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 10951 | |
| 10952 | Use the more standard files `xalloc.h' and `xmalloc.c' instead of |
| 10953 | Bison's `allocate.c' and `alloc.h'. This patch was surprisingly |
| 10954 | difficult and introduced a lot of core dump. It turns out that |
| 10955 | Bison used an implementation of `xmalloc' based on `calloc', and |
| 10956 | at various places it does depend upon the initialization to 0. I |
| 10957 | have not tried to isolate the pertinent places, and all the former |
| 10958 | calls to Bison's `xmalloc' are now using `XCALLOC'. Someday, |
| 10959 | someone should address this issue. |
| 10960 | |
| 10961 | * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove. |
| 10962 | * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New |
| 10963 | files. |
| 10964 | Adjust dependencies. |
| 10965 | * src/warshall.h: New file. |
| 10966 | Propagate. |

| 10968 | 2000-10-02 Akim Demaille <akim@epita.fr> |

| 10970 | Various anti-`extern in *.c' changes. |
| 10971 | |
| 10972 | * src/system.h: Include `assert.h'. |
| 10973 | |
| 10974 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 10975 | |
| 10976 | * src/state.h (nstates, final_state, first_state, first_shift) |

| 10978 | * src/LR0.h: to here. |
| 10979 | Adjust dependencies. |

| 11035 | Propagate its use instead of tedious list of `extern' and |
| 11036 | prototypes. |
| 11037 | * src/reader.c: Formatting changes, topological sort, |

| 11055 | |
| 11056 | * src/output.c (token_actions): Introduce a temporary array, |
| 11057 | YYDEFACT, that makes it possible for this function to use |
| 11058 | output_short_table. |
| 11059 | |
| 11060 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 11061 | |
| 11062 | `user_toknums' is output as a `short[]' in `output.c', while it is |
| 11063 | defined as a `int[]' in `reader.c'. For consistency with the |
| 11064 | other output tables, `user_toknums' is now defined as a table of |
| 11065 | shorts. |
| 11066 | |
| 11067 | * src/reader.c (user_toknums): Be a short table instead of an int |
| 11068 | table. |

| 11078 | |
| 11079 | * src/output.c (output): Topological sort of the functions, in |
| 11080 | order to get rid of the `static' prototypes. |
| 11081 | No longer use `register'. |
| 11082 | * src/output.h: New file. |
| 11083 | Propagate its inclusion in files explicitly prototyping functions |
| 11084 | from output.c. |

| 11106 | inclusion. |
| 11107 | Don't define PARAMS. |
| 11108 | * src/system.h: Define PARAMS. |
| 11109 | Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the |
| 11110 | purpose of config.h. system.h must not try to fix wrong |
| 11111 | definitions in config.h. |

| 11270 | 2000-03-17 Akim Demaille <akim@epita.fr> |
| 11271 | |
| 11272 | * src/Makefile.am (bison.simple): Fix the awk program: quote only |
| 11273 | the file name, not the whole `#line LINE FILE'. |

| 11297 | |
| 11298 | * src/reader.c (copy_definition): Use copy_string and |

| 11300 | `cplus_comment'. |

| 11329 | Change the handling of @s so that they behave exactly like $s. |
| 11330 | There is now a pseudo variable @$ (readble and writable), location |
| 11331 | of the lhs of the rule (by default ranging from the location of |
| 11332 | the first symbol of the rhs, to the location of the last symbol, |
| 11333 | or, if the rhs is empty, YYLLOC). |
| 11334 | |

| 11336 | yyval. |
| 11337 | (yyparse): When providing a default semantic action, provide a |

| 11340 | same way you stack YYVAL. |

| 11342 | (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'. |

| 11345 | translators. |

| 11366 | |
| 11367 | * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to |
| 11368 | remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough. |
| 11369 | One `#if YYDEBUG' remains, since it uses variables which are |
| 11370 | defined only if `YYDEBUG != 0'. |
| 11371 | |
| 11372 | 2000-03-16 Akim Demaille <akim@epita.fr> |
| 11373 | |
| 11374 | * src/bison.s1 (yyparse): Reorganize the definitions of the stacks |

| 11398 | HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by |

| 11405 | (DEFS): Propagate the location of bison library files and of the |
| 11406 | locale files. |
| 11407 | (INCLUDES): Added `-I ..' so that one can compile with srcdir != |
| 11408 | builddir. |
| 11409 | * acinclude.m4: Remove, replaced by the directory m4. |
| 11410 | * m4/Makefile.am (EXTRA_DIST): New variable. |
| 11411 | * m4/gettext.m4: New file, from the fileutils. |

| 12047 | declaration to allow a multi-character symbol as an alias. |
| 12048 | (parse_thong_decl): New function. |

| 12057 | (get_type, packsymbols): Revised most error messages. |
| 12058 | Changed `fatal' to `warnxxx' to avoid aborting for error. |
| 12059 | Revised and use multiple warnxxx functions to avoid using VARARGS1. |
| 12060 | (read_declarations): Improve the error message for |
| 12061 | an invalid character. Do not abort. |
| 12062 | (read_declarations, copy_guard, copy_action): Use |
| 12063 | printable_version to avoid unprintable characters in printed output. |

| 12075 | * src/main.c (main): |
| 12076 | If reader sees an error, don't process the grammar. |
| 12077 | (fatals): Updated to not use VARARGS1. |
| 12078 | (printable_version, int_to_string, warn, warni, warns, warnss) |
| 12079 | (warnsss): New error reporting functions. Avoid abort for error. |
| 12080 | |
| 12081 | * src/lex.h: |
| 12082 | Added THONG and NOOP for alias processing. |
| 12083 | Added SETOPT for the new code that allows setting options with %flags. |
| 12084 | |
| 12085 | * src/lex.c: |
| 12086 | Include getopt.h. Add some extern decls. |
| 12087 | (safegetc): New function to deal with EOF gracefully. |
| 12088 | (literalchar); new function to deal with reading \ escapes. |
| 12089 | (lex): Use literalchar. |
| 12090 | (lex): Implemented "..." tokens. |
| 12091 | (literalchar, lex, parse_percent_token): Made tokenbuffer |
| 12092 | always contain the token. This includes growing the token |
| 12093 | buffer while reading an integer. |
| 12094 | (parse_percent_token): Replaced if-else statement with percent_table. |
| 12095 | (parse_percent_token): Added % declarations as another |
| 12096 | way to specify the flags -n, -l, and -r. Also added hooks for |
| 12097 | -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires |
| 12098 | major changes to files.c. |
| 12099 | (lex) Retain in the incoming stream a character following |
| 12100 | an incorrect '/'. |
| 12101 | (skip_white_space, lex): Revised most error messages |
| 12102 | and changed fatal to warn to avoid aborting. |

| 12108 | Add faction flag |
| 12109 | and actfile file. Handle noparserflag. Both for -n switch. |
| 12110 | |
| 12111 | * src/conflicts.c (resolve_sr_conflict): |
| 12112 | Remove use of alloca. |
