ChangeLog

   1 2000-10-02  Paul Eggert  <eggert@twinsun.com>
   2
   3         * bison.s1 (yyparse): Assign the default value
   4         unconditionally, to avoid a GCC warning and make the parser a
   5         tad smaller.
   6
   7 2000-10-02  Akim Demaille  <akim@epita.fr>
   8
   9         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
  10         options.
  11
  12 2000-10-02  Akim Demaille  <akim@epita.fr>
  13
  14         * src/derives.c, src/print.c, src/reduce.c: To ease the
  15         translation, move some `\n' out of the translated strings.
  16
  17 2000-10-02  Akim Demaille  <akim@epita.fr>
  18
  19         The location tracking mechanism is precious for parse error
  20         messages.  Nevertheless, it is enabled only when `@n' is used in
  21         the grammar, which is a different issue (you can use it in error
  22         message, but not in the grammar per se).  Therefore, there should
  23         be another means to enable it.
  24
  25         * src/getargs.c (getargs): Support `--locations'.
  26         (usage): Report it.
  27         * src/getargs.h (locationsflag): Export it.
  28         * src/lex.c (percent_table): Support `%locations'.
  29         * src/reader.c (yylsp_needed): Remove this variable, now replaced
  30         with `locationsflag'.
  31         * doc/bison.texinfo: Document `--locations' and `%locations'.
  32         Sort the options.
  33         * tests/calc.m4: Test it.
  34
  35         For regularity of the names, replace each
  36         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
  37         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
  38         In addition replace each `flag' with `_flag'.
  39
  40 2000-10-02  Akim Demaille  <akim@epita.fr>
  41
  42         Also test parse error messages, including with YYERROR_VERBOSE.
  43
  44         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
  45         associative).
  46         Use it to check the computations.
  47         Use it to check `nonassoc' is honored.
  48         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
  49         `--yyerror-verbose'.
  50         (_AT_CHECK_CALC): Adjust to this option.
  51         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
  52
  53 2000-10-02  Akim Demaille  <akim@epita.fr>
  54
  55         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
  56         the latter demonstrates a flaw in the handling of non debugging
  57         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
  58         was used in order to simplify:
  59
  60         #if YYDEBUG
  61         if (yydebug)
  62         {
  63         ...
  64         }
  65         #endif
  66
  67         into
  68
  69         if (yydebug)
  70         {
  71         ...
  72         }
  73
  74         unfortunately this leads to a CPP conflict when
  75         `--name-prefix=foo' is used since it produces `#define yydebug
  76         foodebug'.
  77
  78         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
  79         (YYDPRINTF): New macro.
  80         Spread its use.
  81         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
  82         the bison options.
  83         Also test `--verbose', `--defines' and `--name-prefix'.
  84
  85 2000-10-02  Akim Demaille  <akim@epita.fr>
  86
  87         Improve the readability of the produced parsers.
  88
  89         * src/bison.s1: Formatting changes.
  90         Improve the comment related to the `$' mark.
  91         (yydefault): Don't fall through to `yyresume': `goto' there.
  92         * src/output.c (output_parser): When the `$' is met, skip the end
  93         of its line.
  94         New variable, `number_of_dollar_signs', to check there's exactly
  95         one `$' in the parser skeleton.
  96
  97 2000-10-02  Akim Demaille  <akim@epita.fr>
  98
  99         * lib/xstrdup.c: New file, from the fileutils.
 100         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 101         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 102         instead of strlen + xmalloc + strcpy.
 103         * src/symtab.c (copys): Remove, use xstrdup instead.
 104
 105 2000-10-02  Akim Demaille  <akim@epita.fr>
 106
 107         * src/gram.h (associativity): New enum type which replaces the
 108         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 109         `right_assoc', `left_assoc' and `non_assoc'.
 110         Adjust all dependencies.
 111         * src/reader.c: Formatting changes.
 112         (LTYPESTR): Don't define it, use it as a literal in
 113         `reader_output_yylsp'.
 114         * src/symtab.h (symbol_class): New enum type which replaces the
 115         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 116         `sunknown', `stoken and `snterm'.
 117
 118 2000-10-02  Akim Demaille  <akim@epita.fr>
 119
 120         * src/getargs.c (fixed_outfiles): Rename as...
 121         (yaccflag): for consistency and accuracy.
 122         Adjust dependencies.
 123
 124 2000-10-02  Akim Demaille  <akim@epita.fr>
 125
 126         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 127         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 128         difficult and introduced a lot of core dump.  It turns out that
 129         Bison used an implementation of `xmalloc' based on `calloc', and
 130         at various places it does depend upon the initialization to 0.  I
 131         have not tried to isolate the pertinent places, and all the former
 132         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 133         someone should address this issue.
 134
 135         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 136         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 137         files.
 138         Adjust dependencies.
 139         * src/warshall.h: New file.
 140         Propagate.
 141
 142 2000-10-02  Akim Demaille  <akim@epita.fr>
 143
 144         Various anti-`extern in *.c' changes.
 145
 146         * src/system.h: Include `assert.h'.
 147
 148 2000-10-02  Akim Demaille  <akim@epita.fr>
 149
 150         * src/state.h (nstates, final_state, first_state, first_shift)
 151         (first_reduction): Move their exportation from here...
 152         * src/LR0.h: to here.
 153         Adjust dependencies.

 161
 162         * src/LR0.h: New file.

 200         (tryopen, tryclose, openfiles): Rename as...
 201         (xfopen, xfclose, open_files): this.
 202         (stringappend): static.
 203         * src/files.h: Complete the list of exported symbols.
 204         Propagate its use.
 205
 206 2000-10-02  Akim Demaille  <akim@epita.fr>
 207
 208         * src/reader.h: New file.
 209         Propagate its use instead of tedious list of `extern' and

 227
 228 2000-10-02  Akim Demaille  <akim@epita.fr>
 229
 230         * src/output.c (token_actions): Introduce a temporary array,
 231         YYDEFACT, that makes it possible for this function to use
 232         output_short_table.
 233
 234 2000-10-02  Akim Demaille  <akim@epita.fr>
 235
 236         `user_toknums' is output as a `short[]' in `output.c', while it is
 237         defined as a `int[]' in `reader.c'.  For consistency with the
 238         other output tables, `user_toknums' is now defined as a table of
 239         shorts.
 240
 241         * src/reader.c (user_toknums): Be a short table instead of an int
 242         table.

 244
 245         Factor the short table outputs.
 246
 247         * src/output.c (output_short_table): New function.

 250
 251 2000-10-02  Akim Demaille  <akim@epita.fr>
 252
 253         * src/output.c (output): Topological sort of the functions, in
 254         order to get rid of the `static' prototypes.
 255         No longer use `register'.
 256         * src/output.h: New file.
 257         Propagate its inclusion in files explicitly prototyping functions
 258         from output.c.
 259
 260 2000-09-21  Akim Demaille  <akim@epita.fr>
 261
 262         * src/atgeneral.m4: Update from Autoconf.
 263
 264 2000-09-21  Akim Demaille  <akim@epita.fr>
 265
 266         * src/closure.h: New file.
 267         * src/closure.c: Formatting changes, topological sort over the
 268         functions, use of closure.h.
 269         (initialize_closure, finalize_closure):  Rename as...
 270         (new_closure, free_closure): these.  Adjust dependencies.
 271         * src/LR0.c: Formatting changes, topological sort, use of
 272         cloture.h.
 273         (initialize_states): Rename as...
 274         (new_states): this.
 275         * src/Makefile.am (noinst_HEADERS): Adjust.
 276
 277 2000-09-20  Akim Demaille  <akim@epita.fr>
 278
 279         * src/acconfig.h: Don't protect config.h against multiple
 280         inclusion.
 281         Don't define PARAMS.
 282         * src/system.h: Define PARAMS.
 283         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 284         purpose of config.h.  system.h must not try to fix wrong
 285         definitions in config.h.
 286
 287 2000-09-20  Akim Demaille  <akim@epita.fr>
 288

 297         * tests/calc.m4 (_AT_DATA_CALC_Y, AT_DATA_CALC_Y, _AT_CHECK_CALC)
 298         (AT_CHECK_CALC): New macros.
 299         Use these macros to test bison with options `', `--raw',
 300         `--debug', `--yacc', `--yacc --debug'.
 301
 302 2000-09-19  Akim Demaille  <akim@epita.fr>
 303
 304         * src/output.c: Formatting changes.
 305         * src/machine.h: Remove, leaving its contents in...
 306         * src/system.h: here.
 307         Include stdio.h.
 308         Adjust all dependencies on stdio.h and machine.h.
 309         * src/getargs.h: New file.
 310         Let all `extern' declarations about getargs.c be replaced with
 311         inclusion of `getargs.h'.
 312         * src/Makefile.am (noinst_HEADERS): Adjust.
 313
 314         * tests/calc.m4 (yyin): Be initialized in main, not on the global

 322         portable.
 323
 324 2000-09-18  Akim Demaille  <akim@epita.fr>
 325
 326         * configure.in: Append WARNING_CFLAGS to CFLAGS.
 327         * src/Makefile.am (INCLUDES): Don't.
 328         Be ready to fetch headers in lib/.
 329
 330 2000-09-18  Akim Demaille  <akim@epita.fr>
 331
 332         * doc/bison.texinfo: Update the copyright.
 333         ANSIfy and GNUify the examples.
 334         Remove the old menu.
 335
 336 2000-09-18  Akim Demaille  <akim@epita.fr>

 338         First set of tests: use the `calc' example from the documentation.
 339
 340         * src/bison.s1 (yyparse): Condition the code using `yytname' which
 341         is defined only when YYDEBUG is.
 342         * m4/atconfig.m4 (AT_CONFIG): Adjust to Autoconf 2.13.

 371         (get_type, parse_start_decl): Use the same `invalid' message.
 372         (parse_start_decl, parse_union_decl): Use the same `multiple'
 373         message.

 445
 446         * src/Makefile.am (bison.simple): Fix the awk program: quote only
 447         the file name, not the whole `#line LINE FILE'.
 448

 471
 472         * src/reader.c (copy_definition): Use copy_string and
 473         copy_comment.  Removed now unused `match', `ended',
 474         `cplus_comment'.
 475         (copy_comment, copy_string): Moved, to be visible from

 502
 503         Change the handling of @s so that they behave exactly like $s.
 504         There is now a pseudo variable @$ (readble and writable), location
 505         of the lhs of the rule (by default ranging from the location of
 506         the first symbol of the rhs, to the location of the last symbol,
 507         or, if the rhs is empty, YYLLOC).
 508

 510         yyval.
 511         (yyparse): When providing a default semantic action, provide a
 512         default location action.
 513         (after the $): No longer change `*YYLSP', just stack YYLOC the
 514         same way you stack YYVAL.
 515         * src/reader.c (read_declarations): Use warns.
 516         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
 517         (copy_action, case '@'): Likewise.
 518         Use a standard error message, to save useless work from
 519         translators.
 520
 521 2000-03-17  Akim Demaille  <akim@epita.fr>
 522

 540
 541         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
 542         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
 543         One `#if YYDEBUG' remains, since it uses variables which are
 544         defined only if `YYDEBUG != 0'.
 545
 546 2000-03-16  Akim Demaille  <akim@epita.fr>
 547
 548         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

 570         handled via src/Makefile.am.
 571         (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,
 572         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

 580         locale files.
 581         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
 582         builddir.
 583         * acinclude.m4: Remove, replaced by the directory m4.
 584         * m4/Makefile.am (EXTRA_DIST): New variable.
 585         * m4/gettext.m4: New file, from the fileutils.

1201 1995-10-15  Richard Stallman  <rms@gnu.org>
1202
1203         * src/vmsgetargs.c, src/getargs.c:

1217         (readgram): Use `#if 0' around code that accepted %command
1218         inside grammar rules:  The documentation doesn't allow it,
1219         and it will fail since the %command processors scan for the next %.
1220         (parse_token_decl):  Extended the %token
1221         declaration to allow a multi-character symbol as an alias.

1230         (get_type_name, copy_guard, copy_action, readgram)
1231         (get_type, packsymbols):  Revised most error messages.
1232         Changed `fatal' to `warnxxx' to avoid aborting for error.
1233         Revised and use multiple warnxxx functions to avoid using VARARGS1.
1234         (read_declarations): Improve the error message for
1235         an invalid character.  Do not abort.
1236         (read_declarations, copy_guard, copy_action): Use
1237         printable_version to avoid unprintable characters in printed output.
1238         (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
1239         (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
1240         Allow the type of a non-terminal can be given
1241         more than once, as long as all specifications give the same type.
1242
1243         * src/output.c:
1244         (output_headers, output_trailers, output, output_gram)
1245         (output_rule_data): Implement noparserflag variable.
1246         Implement toknumflag variable.
1247         (output): Call reader_output_yylsp to output LTYPESTR.
1248
1249         * src/main.c (main):
1250          If reader sees an error, don't process the grammar.
1251         (fatals): Updated to not use VARARGS1.
1252         (printable_version, int_to_string, warn, warni, warns, warnss)
1253         (warnsss): New error reporting functions.  Avoid abort for error.
1254
1255         * src/lex.h:
1256         Added THONG and NOOP for alias processing.
1257         Added SETOPT for the new code that allows setting options with %flags.
1258
1259         * src/lex.c:

1262         (literalchar); new function to deal with reading \ escapes.
1263         (lex): Use literalchar.
1264         (lex): Implemented "..." tokens.
1265         (literalchar, lex, parse_percent_token): Made tokenbuffer
1266         always contain the token.  This includes growing the token
1267         buffer while reading an integer.
1268         (parse_percent_token): Replaced if-else statement with percent_table.
1269         (parse_percent_token): Added % declarations as another
1270         way to specify the flags -n, -l, and -r.  Also added hooks for
1271         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
1272         major changes to files.c.
1273         (lex) Retain in the incoming stream a character following
1274         an incorrect '/'.
1275         (skip_white_space, lex):  Revised most error messages
1276         and changed fatal to warn to avoid aborting.
1277         (percent_table):  Added %thong declarations.
