ChangeLog

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

 214
 215

 241 2000-10-02  Akim Demaille  <akim@epita.fr>
 242
 243         * src/output.c (token_actions): Introduce a temporary array,
 244         YYDEFACT, that makes it possible for this function to use

 247
 248 2000-10-02  Akim Demaille  <akim@epita.fr>
 249
 250         `user_toknums' is output as a `short[]' in `output.c', while it is
 251         defined as a `int[]' in `reader.c'.  For consistency with the
 252         other output tables, `user_toknums' is now defined as a table of
 253         shorts.
 254
 255         * src/reader.c (user_toknums): Be a short table instead of an int
 256         table.

 265 2000-10-02  Akim Demaille  <akim@epita.fr>
 266
 267         * src/output.c (output): Topological sort of the functions, in
 268         order to get rid of the `static' prototypes.
 269         No longer use `register'.
 270         * src/output.h: New file.
 271         Propagate its inclusion in files explicitly prototyping functions
 272         from output.c.
 273
 274 2000-09-21  Akim Demaille  <akim@epita.fr>
 275

 282         functions, use of closure.h.
 283         (initialize_closure, finalize_closure):  Rename as...
 284         (new_closure, free_closure): these.  Adjust dependencies.
 285         * src/LR0.c: Formatting changes, topological sort, use of
 286         cloture.h.
 287         (initialize_states): Rename as...
 288         (new_states): this.
 289         * src/Makefile.am (noinst_HEADERS): Adjust.
 290
 291 2000-09-20  Akim Demaille  <akim@epita.fr>
 292
 293         * src/acconfig.h: Don't protect config.h against multiple
 294         inclusion.
 295         Don't define PARAMS.
 296         * src/system.h: Define PARAMS.
 297         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 298         purpose of config.h.  system.h must not try to fix wrong
 299         definitions in config.h.
 300
 301 2000-09-20  Akim Demaille  <akim@epita.fr>
 302

 312         (AT_CHECK_CALC): New macros.
 313         Use these macros to test bison with options `', `--raw',
 314         `--debug', `--yacc', `--yacc --debug'.
 315
 316 2000-09-19  Akim Demaille  <akim@epita.fr>
 317
 318         * src/output.c: Formatting changes.

 320         * src/system.h: here.
 321         Include stdio.h.
 322         Adjust all dependencies on stdio.h and machine.h.
 323         * src/getargs.h: New file.
 324         Let all `extern' declarations about getargs.c be replaced with

 327
 328         * tests/calc.m4 (yyin): Be initialized in main, not on the global

 339
 340         * configure.in: Append WARNING_CFLAGS to CFLAGS.
 341         * src/Makefile.am (INCLUDES): Don't.

 343
 344 2000-09-18  Akim Demaille  <akim@epita.fr>
 345
 346         * doc/bison.texinfo: Update the copyright.
 347         ANSIfy and GNUify the examples.

 459
 460         * src/Makefile.am (bison.simple): Fix the awk program: quote only
 461         the file name, not the whole `#line LINE FILE'.
 462

 486         * src/reader.c (copy_definition): Use copy_string and
 487         copy_comment.  Removed now unused `match', `ended',
 488         `cplus_comment'.

 516
 517         Change the handling of @s so that they behave exactly like $s.
 518         There is now a pseudo variable @$ (readble and writable), location
 519         of the lhs of the rule (by default ranging from the location of
 520         the first symbol of the rhs, to the location of the last symbol,
 521         or, if the rhs is empty, YYLLOC).
 522

 524         yyval.
 525         (yyparse): When providing a default semantic action, provide a
 526         default location action.
 527         (after the $): No longer change `*YYLSP', just stack YYLOC the
 528         same way you stack YYVAL.
 529         * src/reader.c (read_declarations): Use warns.
 530         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

 532         Use a standard error message, to save useless work from
 533         translators.
 534

 554
 555         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
 556         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
 557         One `#if YYDEBUG' remains, since it uses variables which are
 558         defined only if `YYDEBUG != 0'.
 559
 560 2000-03-16  Akim Demaille  <akim@epita.fr>
 561
 562         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

 584         handled via src/Makefile.am.
 585         (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,
 586         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

 594         locale files.
 595         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
 596         builddir.
 597         * acinclude.m4: Remove, replaced by the directory m4.
 598         * m4/Makefile.am (EXTRA_DIST): New variable.
 599         * m4/gettext.m4: New file, from the fileutils.

1210 1995-10-16  Richard Stallman  <rms@gnu.org>
1211
1212         * doc/bison.1, doc/bison.rnh:
1213         Add new options.
1214
1215 1995-10-15  Richard Stallman  <rms@gnu.org>
1216
1217         * src/vmsgetargs.c, src/getargs.c:
1218         Added -n, -k, and -raw switches.

1231         (readgram): Use `#if 0' around code that accepted %command
1232         inside grammar rules:  The documentation doesn't allow it,
1233         and it will fail since the %command processors scan for the next %.
1234         (parse_token_decl):  Extended the %token
1235         declaration to allow a multi-character symbol as an alias.
1236         (parse_thong_decl): New function.
1237         (read_declarations): Added %thong declarations.
1238         (read_declarations): Handle NOOP to deal with allowing
1239         % declarations as another means to specify the flags.

1244         (get_type_name, copy_guard, copy_action, readgram)
1245         (get_type, packsymbols):  Revised most error messages.
1246         Changed `fatal' to `warnxxx' to avoid aborting for error.
1247         Revised and use multiple warnxxx functions to avoid using VARARGS1.
1248         (read_declarations): Improve the error message for
1249         an invalid character.  Do not abort.
1250         (read_declarations, copy_guard, copy_action): Use
1251         printable_version to avoid unprintable characters in printed output.
1252         (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
1253         (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
1254         Allow the type of a non-terminal can be given
1255         more than once, as long as all specifications give the same type.
1256
1257         * src/output.c:
1258         (output_headers, output_trailers, output, output_gram)
1259         (output_rule_data): Implement noparserflag variable.
1260         Implement toknumflag variable.
1261         (output): Call reader_output_yylsp to output LTYPESTR.
1262
1263         * src/main.c (main):
1264          If reader sees an error, don't process the grammar.
1265         (fatals): Updated to not use VARARGS1.
1266         (printable_version, int_to_string, warn, warni, warns, warnss)
1267         (warnsss): New error reporting functions.  Avoid abort for error.
1268
1269         * src/lex.h:
1270         Added THONG and NOOP for alias processing.
1271         Added SETOPT for the new code that allows setting options with %flags.
1272
1273         * src/lex.c:
1274         Include getopt.h.  Add some extern decls.
1275         (safegetc): New function to deal with EOF gracefully.
1276         (literalchar); new function to deal with reading \ escapes.
1277         (lex): Use literalchar.
1278         (lex): Implemented "..." tokens.
1279         (literalchar, lex, parse_percent_token): Made tokenbuffer
1280         always contain the token.  This includes growing the token
1281         buffer while reading an integer.
1282         (parse_percent_token): Replaced if-else statement with percent_table.
1283         (parse_percent_token): Added % declarations as another
1284         way to specify the flags -n, -l, and -r.  Also added hooks for
1285         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
1286         major changes to files.c.
1287         (lex) Retain in the incoming stream a character following
1288         an incorrect '/'.
1289         (skip_white_space, lex):  Revised most error messages
1290         and changed fatal to warn to avoid aborting.
1291         (percent_table):  Added %thong declarations.
1292
1293         * src/gram.h: Comment changes.
