+
+ * bison.s1 (yyparse): Assign the default value
+ unconditionally, to avoid a GCC warning and make the parser a
+ tad smaller.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ * src/getargs.c (getargs): Don't dump `--help' on unrecognized
+ options.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ * src/derives.c, src/print.c, src/reduce.c: To ease the
+ translation, move some `\n' out of the translated strings.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ The location tracking mechanism is precious for parse error
+ messages. Nevertheless, it is enabled only when `@n' is used in
+ the grammar, which is a different issue (you can use it in error
+ message, but not in the grammar per se). Therefore, there should
+ be another means to enable it.
+
+ * src/getargs.c (getargs): Support `--locations'.
+ (usage): Report it.
+ * src/getargs.h (locationsflag): Export it.
+ * src/lex.c (percent_table): Support `%locations'.
+ * src/reader.c (yylsp_needed): Remove this variable, now replaced
+ with `locationsflag'.
+ * doc/bison.texinfo: Document `--locations' and `%locations'.
+ Sort the options.
+ * tests/calc.m4: Test it.
+
+ For regularity of the names, replace each
+ (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
+ (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
+ In addition replace each `flag' with `_flag'.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ Also test parse error messages, including with YYERROR_VERBOSE.
+
+ * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
+ associative).
+ Use it to check the computations.
+ Use it to check `nonassoc' is honored.
+ (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
+ `--yyerror-verbose'.
+ (_AT_CHECK_CALC): Adjust to this option.
+ (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ Test also `--verbose', `--defines' and `--name-prefix'. Testing
+ the latter demonstrates a flaw in the handling of non debugging
+ parsers introduced by myself on 2000-03-16: `#define yydebug 0'
+ was used in order to simplify:
+
+ #if YYDEBUG
+ if (yydebug)
+ {
+ ...
+ }
+ #endif
+
+ into
+
+ if (yydebug)
+ {
+ ...
+ }
+
+ unfortunately this leads to a CPP conflict when
+ `--name-prefix=foo' is used since it produces `#define yydebug
+ foodebug'.
+
+ * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
+ (YYDPRINTF): New macro.
+ Spread its use.
+ * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
+ the bison options.
+ Also test `--verbose', `--defines' and `--name-prefix'.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ Improve the readability of the produced parsers.
+
+ * src/bison.s1: Formatting changes.
+ Improve the comment related to the `$' mark.
+ (yydefault): Don't fall through to `yyresume': `goto' there.
+ * src/output.c (output_parser): When the `$' is met, skip the end
+ of its line.
+ New variable, `number_of_dollar_signs', to check there's exactly
+ one `$' in the parser skeleton.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ * lib/xstrdup.c: New file, from the fileutils.
+ * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
+ (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
+ instead of strlen + xmalloc + strcpy.
+ * src/symtab.c (copys): Remove, use xstrdup instead.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ * src/gram.h (associativity): New enum type which replaces the
+ former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
+ `right_assoc', `left_assoc' and `non_assoc'.
+ Adjust all dependencies.
+ * src/reader.c: Formatting changes.
+ (LTYPESTR): Don't define it, use it as a literal in
+ `reader_output_yylsp'.
+ * src/symtab.h (symbol_class): New enum type which replaces the
+ former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
+ `sunknown', `stoken and `snterm'.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ * src/getargs.c (fixed_outfiles): Rename as...
+ (yaccflag): for consistency and accuracy.
+ Adjust dependencies.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ Use the more standard files `xalloc.h' and `xmalloc.c' instead of
+ Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
+ difficult and introduced a lot of core dump. It turns out that
+ Bison used an implementation of `xmalloc' based on `calloc', and
+ at various places it does depend upon the initialization to 0. I
+ have not tried to isolate the pertinent places, and all the former
+ calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
+ someone should address this issue.
+
+ * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
+ * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
+ files.
+ Adjust dependencies.
+ * src/warshall.h: New file.
+ Propagate.
+
+2000-10-02 Akim Demaille <akim@epita.fr>

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

+ (first_reduction): Move their exportation from here...
+ * src/LR0.h: to here.
+ Adjust dependencies.
+ * src/getargs.c (statisticsflag): New variable.
+ Add support for `--statistics'.
+ Adjust dependencies.
+
+ Remove a lot of now useless `extern' statements in most files.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.h: New file.
+ Propagate its use.

+ Propagate its inclusion.
+ * src/nullable.c: Formatting changes.

+
+ * src/files.c: Formatting changes.

+ (xfopen, xfclose, open_files): this.
+ (stringappend): static.
+ * src/files.h: Complete the list of exported symbols.
+ Propagate its use.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ * src/reader.h: New file.
+ Propagate its use instead of tedious list of `extern' and
+ prototypes.

+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ * src/output.c (token_actions): Introduce a temporary array,
+ YYDEFACT, that makes it possible for this function to use
+ output_short_table.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ `user_toknums' is output as a `short[]' in `output.c', while it is
+ defined as a `int[]' in `reader.c'. For consistency with the
+ other output tables, `user_toknums' is now defined as a table of
+ shorts.
+
+ * src/reader.c (user_toknums): Be a short table instead of an int
+ table.
+ Adjust dependencies.
+
+ Factor the short table outputs.
+
+ * src/output.c (output_short_table): New function.
+ * src/output.c (output_gram, output_stos, output_rule_data)
+ (output_base, output_table, output_check): Use it.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ * src/output.c (output): Topological sort of the functions, in
+ order to get rid of the `static' prototypes.
+ No longer use `register'.

+ from output.c.

+ inclusion.
