ChangeLog

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

 229 2000-10-02  Akim Demaille  <akim@epita.fr>
 230
 231         * src/output.c (token_actions): Introduce a temporary array,
 232         YYDEFACT, that makes it possible for this function to use

 235
 236 2000-10-02  Akim Demaille  <akim@epita.fr>
 237
 238         `user_toknums' is output as a `short[]' in `output.c', while it is
 239         defined as a `int[]' in `reader.c'.  For consistency with the
 240         other output tables, `user_toknums' is now defined as a table of
 241         shorts.
 242
 243         * src/reader.c (user_toknums): Be a short table instead of an int
 244         table.

 253 2000-10-02  Akim Demaille  <akim@epita.fr>
 254
 255         * src/output.c (output): Topological sort of the functions, in
 256         order to get rid of the `static' prototypes.
 257         No longer use `register'.
 258         * src/output.h: New file.
 259         Propagate its inclusion in files explicitly prototyping functions
 260         from output.c.

 272         (new_closure, free_closure): these.  Adjust dependencies.
 273         * src/LR0.c: Formatting changes, topological sort, use of
 274         cloture.h.
 275         (initialize_states): Rename as...
 276         (new_states): this.
 277         * src/Makefile.am (noinst_HEADERS): Adjust.
 278
 279 2000-09-20  Akim Demaille  <akim@epita.fr>
 280
 281         * src/acconfig.h: Don't protect config.h against multiple
 282         inclusion.
 283         Don't define PARAMS.
 284         * src/system.h: Define PARAMS.
 285         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 286         purpose of config.h.  system.h must not try to fix wrong
 287         definitions in config.h.
 288
 289 2000-09-20  Akim Demaille  <akim@epita.fr>
 290

 301         Use these macros to test bison with options `', `--raw',
 302         `--debug', `--yacc', `--yacc --debug'.
 303
 304 2000-09-19  Akim Demaille  <akim@epita.fr>
 305
 306         * src/output.c: Formatting changes.

 308         * src/system.h: here.
 309         Include stdio.h.
 310         Adjust all dependencies on stdio.h and machine.h.
 311         * src/getargs.h: New file.
 312         Let all `extern' declarations about getargs.c be replaced with

 315
 316         * tests/calc.m4 (yyin): Be initialized in main, not on the global

 327
 328         * configure.in: Append WARNING_CFLAGS to CFLAGS.

 332 2000-09-18  Akim Demaille  <akim@epita.fr>
 333
 334         * doc/bison.texinfo: Update the copyright.
 335         ANSIfy and GNUify the examples.

 337

 373         (get_type, parse_start_decl): Use the same `invalid' message.

 446 2000-03-17  Akim Demaille  <akim@epita.fr>
 447
 448         * src/Makefile.am (bison.simple): Fix the awk program: quote only
 449         the file name, not the whole `#line LINE FILE'.
 450
 451 2000-03-17  Akim Demaille  <akim@epita.fr>
 452
 453         On syntax errors, report the token on which we choked.

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

 502
 503 2000-03-17  Akim Demaille  <akim@epita.fr>
 504
 505         Change the handling of @s so that they behave exactly like $s.
 506         There is now a pseudo variable @$ (readble and writable), location
 507         of the lhs of the rule (by default ranging from the location of
 508         the first symbol of the rhs, to the location of the last symbol,
 509         or, if the rhs is empty, YYLLOC).
 510
 511         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
 512         yyval.
 513         (yyparse): When providing a default semantic action, provide a
 514         default location action.
 515         (after the $): No longer change `*YYLSP', just stack YYLOC the
 516         same way you stack YYVAL.
 517         * src/reader.c (read_declarations): Use warns.
 518         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
 519         (copy_action, case '@'): Likewise.
 520         Use a standard error message, to save useless work from
 521         translators.
 522
 523 2000-03-17  Akim Demaille  <akim@epita.fr>
 524

 542
 543         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
 544         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
 545         One `#if YYDEBUG' remains, since it uses variables which are
 546         defined only if `YYDEBUG != 0'.
 547
 548 2000-03-16  Akim Demaille  <akim@epita.fr>
 549
 550         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

 566         * configure.in (XPFILE, XPFILE1, LOCALEDIR): Remove, handled by

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

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

1201         Add new options.
1202
1203 1995-10-15  Richard Stallman  <rms@gnu.org>
1204
1205         * src/vmsgetargs.c, src/getargs.c:
1206         Added -n, -k, and -raw switches.

1219         (readgram): Use `#if 0' around code that accepted %command
1220         inside grammar rules:  The documentation doesn't allow it,
1221         and it will fail since the %command processors scan for the next %.
1222         (parse_token_decl):  Extended the %token
1223         declaration to allow a multi-character symbol as an alias.
1224         (parse_thong_decl): New function.

1232         (get_type_name, copy_guard, copy_action, readgram)
1233         (get_type, packsymbols):  Revised most error messages.
1234         Changed `fatal' to `warnxxx' to avoid aborting for error.
1235         Revised and use multiple warnxxx functions to avoid using VARARGS1.
1236         (read_declarations): Improve the error message for
1237         an invalid character.  Do not abort.
1238         (read_declarations, copy_guard, copy_action): Use
1239         printable_version to avoid unprintable characters in printed output.
1240         (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
1241         (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
1242         Allow the type of a non-terminal can be given
1243         more than once, as long as all specifications give the same type.
1244
1245         * src/output.c:
1246         (output_headers, output_trailers, output, output_gram)
1247         (output_rule_data): Implement noparserflag variable.
1248         Implement toknumflag variable.
1249         (output): Call reader_output_yylsp to output LTYPESTR.
1250
1251         * src/main.c (main):
1252          If reader sees an error, don't process the grammar.
1253         (fatals): Updated to not use VARARGS1.
1254         (printable_version, int_to_string, warn, warni, warns, warnss)
1255         (warnsss): New error reporting functions.  Avoid abort for error.
1256
1257         * src/lex.h:
1258         Added THONG and NOOP for alias processing.
1259         Added SETOPT for the new code that allows setting options with %flags.
1260
1261         * src/lex.c:
1262         Include getopt.h.  Add some extern decls.
1263         (safegetc): New function to deal with EOF gracefully.
1264         (literalchar); new function to deal with reading \ escapes.
1265         (lex): Use literalchar.
1266         (lex): Implemented "..." tokens.
1267         (literalchar, lex, parse_percent_token): Made tokenbuffer
1268         always contain the token.  This includes growing the token
1269         buffer while reading an integer.
1270         (parse_percent_token): Replaced if-else statement with percent_table.
1271         (parse_percent_token): Added % declarations as another
1272         way to specify the flags -n, -l, and -r.  Also added hooks for
1273         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
1274         major changes to files.c.
1275         (lex) Retain in the incoming stream a character following
1276         an incorrect '/'.
1277         (skip_white_space, lex):  Revised most error messages
1278         and changed fatal to warn to avoid aborting.
1279         (percent_table):  Added %thong declarations.
