   1 2001-11-30  Akim Demaille  <akim@epita.fr>
   2
   3         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty

   5
   6 2001-11-30  Akim Demaille  <akim@epita.fr>
   7
   8         Instead of mapping the LHS of unused rules to -1, keep the LHS
   9         valid, but flag the rules as invalid.
  10
  11         * src/gram.h (rule_t): `useful' is a new member.
  12         * src/print.c (print_grammar): Adjust.

  19
  20         * src/reduce.c (reduce_output): Formatting changes.

  23         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
  24
  25 2001-11-30  Akim Demaille  <akim@epita.fr>
  26
  27         * src/reduce.c (nonterminals_reduce): Instead of throwing away
  28         useless nonterminals, move them at the end of the symbol arrays.
  29         (reduce_output): Adjust.
  30         * tests/reduce.at (Useless Nonterminals): Adjust.
  31
  32 2001-11-30  Akim Demaille  <akim@epita.fr>
  33
  34         * src/reduce.c: Various comment/formatting changes.
  35         (nonterminals_reduce): New, extracted from...
  36         (reduce_grammar_tables): here.
  37         (reduce_grammar): Call nonterminals_reduce.
  38
  39 2001-11-29  Paul Eggert  <eggert@twinsun.com>
  40
  41         * src/bison.simple (YYSTACK_REALLOC): Remove.
  42         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
  43         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
  44         New macros.
  45         (union yyalloc): New type.
  46         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
  47         an arbitrary restriction on hosts where size_t is wider than int.
  48
  49         (yyparse): Don't dump core if alloca or malloc fails; instead, report
  50         a parser stack overflow.  Allocate just one block of memory for all
  51         three stacks, instead of allocating three blocks; this typically is
  52         faster and reduces fragmentation.
  53
  54         Do not limit the number of items in the stack to a value that fits
  55         in 'int', as this is an arbitrary limit on hosts with 64-bit
  56         size_t and 32-bit int.
  57
  58 2001-11-29  Marc Autret  <autret_m@epita.fr>

 116 2001-11-28  Akim Demaille  <akim@epita.fr>
 117
 118         * src/closure.c (closure): No longer optimize the special case

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

 487         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
 488         use abs. path to find config.h.
 489         * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

 510         * src/conflicts.c (conflict_report): Additional useless pair of
 511         braces to pacify GCC's warnings for `if () if () {} else {}'.
 512         * src/lex.c (parse_percent_token): Replace equal_offset with
 513         arg_offset.
 514         arg is const.
 515         Be sure to strdup `arg' when used, since there is no reason for
 516         token_buffer not to change.

 612         * src/reader.c (parse_union_decl): Output yystype/YYSTYPE as we do
 613         with yyltype/YYLTYPE.  This allows inclusion of the generated

1825 2001-07-14  Akim Demaille  <akim@epita.fr>
1826
1827         * config/: New.
1828         * configure.in: Require Autoconf 2.50.
1829         Update to gettext 0.10.38.
1830
1831 2001-03-16  Akim Demaille  <akim@epita.fr>
1832
1833         * doc/bison.texinfo: ANSIfy the examples.
1834
1835 2001-03-16  Akim Demaille  <akim@epita.fr>
1836
1837         * getargs.c (skeleton): New variable.
1838         (longopts): --skeleton is a new option.
1839         (shortopts, getargs): -S is a new option.
1840         * getargs.h: Declare skeleton.
1841         * output.c (output_parser): Use it.
1842
1843 2001-03-16  Akim Demaille  <akim@epita.fr>
1844
1845         * m4/strerror_r.m4: New.
1846         * m4/error.m4: Run AC_FUNC_STRERROR_R.

1852
1853 2001-02-21  Akim Demaille  <akim@epita.fr>
1854
1855         * src/reader.c (gensym): `gensym_count' is your own.
1856         Use a static buf to create the symbol name, as token_buffer is no
1857         longer a buffer.
1858
1859 2001-02-08  Akim Demaille  <akim@epita.fr>
1860
1861         * src/conflicts.c (conflict_report): Be sure not to append to res
1862         between two calls, which could happen if both first sprintf were
1863         skipped, but not the first cp += strlen.
1864
1865 2001-02-08  Akim Demaille  <akim@epita.fr>
1866
1867         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
1868         New, from fileutils 4.0.37.
1869         * configure.in: Require Autoconf 2.49c.  I took some time before
1870         making this decision.  This is the only way out for portability
1871         issues in Bison, it would mean way too much duplicate effort to
1872         import in Bison features implemented in 2.49c since 2.13.
1873         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
1874
1875 2001-02-02  Akim Demaille  <akim@epita.fr>
1876
1877         * lib/malloc.c, lib/realloc.c: New, from the fileutils 4.0.37.

1880 2001-01-19  Akim Demaille  <akim@epita.fr>
1881
1882         Get rid of the ad hoc handling of token_buffer in the scanner: use
1883         the obstacks.
1884
1885         * src/lex.c (token_obstack): New.
1886         (init_lex): Initialize it.  No longer call...
1887         (grow_token_buffer): this.  Remove it.
1888         Adjust all the places which used it to use the obstack.
1889
1890 2001-01-19  Akim Demaille  <akim@epita.fr>
1891
1892         * src/lex.h: Rename all the tokens:
1893         s/\bENDFILE\b/tok_eof/g;
1894         s/\bIDENTIFIER\b/tok_identifier/g;
1895         etc.
1896         Let them be enums, not #define, to ease debugging.
1897         Adjust all the code.
1898
1899 2001-01-18  Akim Demaille  <akim@epita.fr>
1900
1901         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
1902         * src/lex.c (maxtoken, grow_token_buffer): Static.
1903
1904 2001-01-18  Akim Demaille  <akim@epita.fr>
1905
1906         Since we now use obstacks, more % directives can be enabled.
1907
1908         * src/lex.c (percent_table): Also accept `%yacc',
1909         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
1910         `%debug'.
1911         Handle the actions for `%semantic_parser' and `%pure_parser' here,
1912         instead of returning a token.
1913         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
1914         * src/reader.c (read_declarations): Adjust.
1915         * src/files.c (open_files): Don't call `compute_base_names', don't
1916         compute `attrsfile' since they depend upon data which might be
1917         *in* the input file now.
1918         (output_files): Do it here.
1919         * src/output.c (output_headers): Document the fact that this patch
1920         introduces a guaranteed SEGV for semantic parsers.
1921         * doc/bison.texinfo: Document them.
1922         * tests/suite.at: Exercise these %options.
1923
1924 2000-12-20  Akim Demaille  <akim@epita.fr>
1925
1926         Also handle the output file (--verbose) with obstacks.
1927
1928         * files.c (foutput): Remove.
1929         (output_obstack): New.
1930         Adjust all dependencies.

1932         * src/system.h (obstack_grow_string): Rename as...
1933         (obstack_sgrow): this.  Be ready to work with non literals.

1938         * src/files.c (open_files): Fix the computation of short_base_name
1939         in the case of `-o foo.tab.c'.
1940
1941 2000-12-20  Akim Demaille  <akim@epita.fr>
1942
1943         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
1944         (copy_dollar): Now that everything uses obstacks, get rid of the
1945         FILE * parameters.
1946
1947 2000-12-20  Akim Demaille  <akim@epita.fr>
1948
1949         * src/files.c (open_files): Actually the `.output' file is based
1950         on the short_base_name, not base_name.
1951         * tests/suite.at (Checking output file names): Adjust.
1952
1953 2000-12-20  Akim Demaille  <akim@epita.fr>
1954
1955         * src/bison.s1: Remove, we now use directly...

1957         * src/Makefile.am: Use pkgdata instead of data.

1974         Adjust dependencies.
1975
1976 2000-12-19  Akim Demaille  <akim@epita.fr>
1977
1978         * src/files.c (strsuffix): New.
1979         (stringappend): Be just like strcat but allocate.
1980         (base_names): Eve out from open_files.
1981         Try to simplify the rather hairy computation of base_name and
1982         short_base_name.
1983         (open_files): Use it.
1984         * tests/suite.at (Checking output file names): New test.

1994
1995 2000-12-19  Akim Demaille  <akim@epita.fr>
1996
1997         * src/output.c (output_parser): Compute the `#line' lines when
1998         there are.
1999         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.

2001
2002 2000-12-19  Akim Demaille  <akim@epita.fr>
2003
2004         Let the handling of the skeleton files be local to the procedures
2005         that use it.
2006
2007         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
2008         longer static.

2023
2024         * src/files.c (open_files): Yipee!  We no longer need all the code
2025         looking for `/tmp' since we have no tmp file.
2026

2028
2029         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

2055
2056         * lib/obstack.h: Formatting changes.
2057         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
2058         prevents type checking.
2059         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
2060         cast the value to (void *): assigning a `foo *' to a `void *'
2061         variable is valid.
2062         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

2098
2099 2000-11-07  Akim Demaille  <akim@epita.fr>
2100
2101         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
2102         Merge in a single CPP if/else.
2103
2104 2000-11-07  Akim Demaille  <akim@epita.fr>
2105
2106         * src/output.c (output): Remove useless variables.
2107         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
2108         argument `data' for consistency with the prototypes.
2109         Qualify it `const'.
2110         (obstack_copy, obstack_copy0): Rename the second argument as
2111         `address' for consistency.  Qualify it `const'.

2117 2000-11-03  Akim Demaille  <akim@epita.fr>

2121         Adjust dependencies.
2122
2123 2000-11-03  Akim Demaille  <akim@epita.fr>
2124
2125         For some reason, this was not applied.
2126
2127         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

2131

2142         Use `obstack_save'.
2143         * src/main.c (main): Don't use `atexit' to register `done', since
2144         it no longer has to remove tmp files, just call `output_files'
2145         when there are no errors.
2146
2147 2000-11-02  Akim Demaille  <akim@epita.fr>
2148
2149         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

2252         Reported by Piotr Gackiewicz, and fixed by Neil Booth.

2260
2261         * src/reader.c (parse_expect_decl): Keep `count' within the size

2263         From Neil Booth.
2264
2265 2000-10-02  Paul Eggert  <eggert@twinsun.com>
2266
2267         * bison.s1 (yyparse): Assign the default value
2268         unconditionally, to avoid a GCC warning and make the parser a
2269         tad smaller.
2270
2271 2000-10-02  Akim Demaille  <akim@epita.fr>
2272

2280
2281 2000-10-02  Akim Demaille  <akim@epita.fr>
2282
2283         The location tracking mechanism is precious for parse error
2284         messages.  Nevertheless, it is enabled only when `@n' is used in
2285         the grammar, which is a different issue (you can use it in error
2286         message, but not in the grammar per se).  Therefore, there should
2287         be another means to enable it.
2288
2289         * src/getargs.c (getargs): Support `--locations'.
2290         (usage): Report it.
2291         * src/getargs.h (locationsflag): Export it.
2292         * src/lex.c (percent_table): Support `%locations'.
2293         * src/reader.c (yylsp_needed): Remove this variable, now replaced
2294         with `locationsflag'.
2295         * doc/bison.texinfo: Document `--locations' and `%locations'.
2296         Sort the options.
2297         * tests/calc.m4: Test it.
2298
2299         For regularity of the names, replace each
2300         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
2301         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
2302         In addition replace each `flag' with `_flag'.
2303
2304 2000-10-02  Akim Demaille  <akim@epita.fr>
2305
2306         Also test parse error messages, including with YYERROR_VERBOSE.
2307
2308         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
2309         associative).
2310         Use it to check the computations.
2311         Use it to check `nonassoc' is honored.
2312         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
2313         `--yyerror-verbose'.
2314         (_AT_CHECK_CALC): Adjust to this option.
2315         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
2316
2317 2000-10-02  Akim Demaille  <akim@epita.fr>
2318
2319         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
2320         the latter demonstrates a flaw in the handling of non debugging
2321         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
2322         was used in order to simplify:
2323
2324         #if YYDEBUG
2325         if (yydebug)
2326         {
2327         ...
2328         }
2329         #endif
2330
2331         into
2332
2333         if (yydebug)
2334         {
2335         ...
2336         }
2337
2338         unfortunately this leads to a CPP conflict when
2339         `--name-prefix=foo' is used since it produces `#define yydebug
2340         foodebug'.
2341
2342         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
2343         (YYDPRINTF): New macro.
2344         Spread its use.
2345         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
2346         the bison options.
2347         Also test `--verbose', `--defines' and `--name-prefix'.
2348
2349 2000-10-02  Akim Demaille  <akim@epita.fr>
2350
2351         Improve the readability of the produced parsers.
2352
2353         * src/bison.s1: Formatting changes.
2354         Improve the comment related to the `$' mark.
2355         (yydefault): Don't fall through to `yyresume': `goto' there.
2356         * src/output.c (output_parser): When the `$' is met, skip the end
2357         of its line.
2358         New variable, `number_of_dollar_signs', to check there's exactly
2359         one `$' in the parser skeleton.
2360
2361 2000-10-02  Akim Demaille  <akim@epita.fr>
2362
2363         * lib/xstrdup.c: New file, from the fileutils.
2364         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
2365         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
2366         instead of strlen + xmalloc + strcpy.
2367         * src/symtab.c (copys): Remove, use xstrdup instead.
2368
2369 2000-10-02  Akim Demaille  <akim@epita.fr>
2370
2371         * src/gram.h (associativity): New enum type which replaces the
2372         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
2373         `right_assoc', `left_assoc' and `non_assoc'.
2374         Adjust all dependencies.
2375         * src/reader.c: Formatting changes.
2376         (LTYPESTR): Don't define it, use it as a literal in
2377         `reader_output_yylsp'.
2378         * src/symtab.h (symbol_class): New enum type which replaces the
2379         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
2380         `sunknown', `stoken and `snterm'.
2381
2382 2000-10-02  Akim Demaille  <akim@epita.fr>
2383
2384         * src/getargs.c (fixed_outfiles): Rename as...

2386         Adjust dependencies.
2387
2388 2000-10-02  Akim Demaille  <akim@epita.fr>
2389
2390         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
2391         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
2392         difficult and introduced a lot of core dump.  It turns out that
2393         Bison used an implementation of `xmalloc' based on `calloc', and
2394         at various places it does depend upon the initialization to 0.  I
2395         have not tried to isolate the pertinent places, and all the former
2396         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
2397         someone should address this issue.
2398
2399         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
2400         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

2498 2000-10-02  Akim Demaille  <akim@epita.fr>
2499
2500         `user_toknums' is output as a `short[]' in `output.c', while it is
2501         defined as a `int[]' in `reader.c'.  For consistency with the
2502         other output tables, `user_toknums' is now defined as a table of

2549         definitions in config.h.

2686         * configure.in: Adjust.
2687         (LIBOBJS): Although not used yet, AC_SUBST it, otherwise it's

2711         the file name, not the whole `#line LINE FILE'.
2712
2713 2000-03-17  Akim Demaille  <akim@epita.fr>
2714
2715         On syntax errors, report the token on which we choked.
2716
2717         * src/bison.s1 (yyparse): In the label yyerrlab, when

2737         copy_comment.  Removed now unused `match', `ended',
2738         `cplus_comment'.
2739         (copy_comment, copy_string): Moved, to be visible from
2740         copy_definition.

2743
2744         * src/reader.c (copy_string): Declare `static inline'.  No

2766
2767         Change the handling of @s so that they behave exactly like $s.
2768         There is now a pseudo variable @$ (readble and writable), location
2769         of the lhs of the rule (by default ranging from the location of
2770         the first symbol of the rhs, to the location of the last symbol,
2771         or, if the rhs is empty, YYLLOC).
2772
2773         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
2774         yyval.
2775         (yyparse): When providing a default semantic action, provide a
2776         default location action.
2777         (after the $): No longer change `*YYLSP', just stack YYLOC the
2778         same way you stack YYVAL.
2779         * src/reader.c (read_declarations): Use warns.
2780         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
2781         (copy_action, case '@'): Likewise.
2782         Use a standard error message, to save useless work from
2783         translators.
2784
2785 2000-03-17  Akim Demaille  <akim@epita.fr>

2804
2805         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
2806         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
2807         One `#if YYDEBUG' remains, since it uses variables which are
2808         defined only if `YYDEBUG != 0'.
2809
2810 2000-03-16  Akim Demaille  <akim@epita.fr>
2811
2812         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

2834         handled via src/Makefile.am.

2836         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

2842         the proper line number and file name.
2843         (DEFS): Propagate the location of bison library files and of the
2844         locale files.
2845         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
2846         builddir.
2847         * acinclude.m4: Remove, replaced by the directory m4.
2848         * m4/Makefile.am (EXTRA_DIST): New variable.
2849         * m4/gettext.m4: New file, from the fileutils.
