+2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/files.c (tr): Change return type to void.
+ * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
+ has been called previously for the same key.
+ (muscle_find): Return storage instead of value so that
+ --enable-gcc-warnings doesn't produce warnings that the return discards
+ const. aver that the value and storage are the same since storage
+ could potentially be NULL when value is not.
+ * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
+ same as 0.
+
+2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
+ the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
+ us a slightly cleaner distribution, and also works.
+ * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
+ gnulib changes.
+
+2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
+ and Paul Eggert <eggert@cs.ucla.edu>
+
+ Don't let Bison leak memory except when it complains.
+ * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
+ (spec_defines_file, dir_prefix): Now char *, not const char *,
+ since they are freed.
+ * src/files.c: Likewise.
+ (all_but_ext, all_but_tab_ext, src_extension, header_extension):
+ Likewise.
+ (tr): Now operates in-place. All uses changed.
+ (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
+ values.
+ (compute_file_name_parts, compute_output_file_names): Don't store
+ read-only data in variables that will be freed.
+ (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
+ src_extension, and header_extension.
+ (output_file_names_free): New public function to free
+ spec_verbose_file, spec_graph_file, spec_defines_file,
+ parser_file_name, and dir_prefix.
+ * src/getargs.c (getargs): Don't store read-only data in variables that
+ will be freed.
+ * src/main.c (main): Invoke output_file_names_free, code_scanner_free
+ (which previously existed but was unused), and quotearg_free.
+ * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
+ * src/muscle_tab.c: Likewise.
+ (muscle_entry): Make the value char const *,
+ and add a new storage member that is char * and can be freed.
+ (muscle_entry_free): New private function.
+ (muscle_init): Use it instead of free.
+ (muscle_insert, muscle_grow): Update and use new storage member.
+ (muscle_code_grow): Free the string passed to muscle_grow
+ since it's not needed anymore.
+ * src/parse-gram.y (%union): Make `chars' member a `char const *', and

+ ("{...}"): Declare semantic type as code.
+ * src/scan-code.h (translate_rule_action):
+ (translate_symbol_action, translate_code, translate_action): Return
+ `char const *' rather than `char *' since external code should not free
+ these strings.
+ * src/scan-code.l: Likewise.
+ * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
+ which is "{...}" in the parser.
+ * tests/Makefile.am (maintainer-check-valgrind): Set
+ VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
+ Valgrind.
+ * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
+ complain.
+ * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
+ expecting a non-zero exit status sets --leak-check=summary and
+ --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
+ this case, and we don't want to hear about it.
+
+2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap (runtime-po/Makevars): Derive from po/Makevars
+ instead of from the template, to simplify configuration a bit.

+
+2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Disable unset/unused mid-rule value warnings by default, and recognize
+ --warnings=midrule-values to enable them. Discussed starting at
+ <http://lists.gnu.org/archive/html/help-bison/2006-10/msg00030.html>.
+ * NEWS (2.3a+): Mention.

+ warnings): Add entry for midrule-values subargument.
+ * src/reader.c (symbol_should_be_used): Don't return true just because
+ the value is a set/used mid-rule value unless

+ * tests/input.at (Unused values, Unused values before symbol
+ declarations): Run tests with and without --warnings=midrule-values.
+
+ * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
+ than LIST_FREE directly.
+
+2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Finish implementing --warnings=error, which should not be implied by
+ --warnings=all (or by its synonyms -W and --warnings without

+ warnings are being treated as errors and to record an error if so.
+ Invoke...
+ (warn_at, warn): ... here.
+ * src/getargs.c (warnings_args, warnings_types): Reorder so that
+ "error - warnings are errors" does not appear above "all - all of the
+ above".
+ (getargs): For -W and --warnings without subarguments, don't let
+ FLAGS_ARGMATCH set warnings_error in warnings_flag.
+ * src/getargs.h (enum warnings): Unset warnings_error in warnings_all.

+
+2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Split the default %destructor/%printer into two kinds: <*> and <!>.
+ Discussed starting at

+ * NEWS (2.3a+): Mention.
+ * doc/bison.texinfo (Freeing Discarded Symbols): Document this and the

+ (TYPE_TAG_NONE): Add as <!>.
+ (generic_symlist_item): Remove RHS for %symbol-default and add RHS's
+ for <*> and <!>.
+ * src/scan-gram.l (PERCENT_SYMBOL_DEFAULT): Remove.

+ default_printer, default_printer_location): Split each into tagged and
+ tagless versions.
+ (symbol_destructor_get, symbol_destructor_location_get,
+ symbol_printer_get, symbol_printer_location_get): Implement tagged
+ default and tagless default cases.
+ (default_destructor_set, default_printer_set): Split each into tagged
+ and tagless versions.
+ * src/symtab.h: Update prototypes.
+ * tests/actions.at (Default %printer and %destructor): Rename to...
+ (Default tagless %printer and %destructor): ... this, and extend.

+ Don't apply the default %destructor/%printer to an unreferenced midrule
+ value. Mentioned at

+
+ Warn about unset midrule $$ if the corresponding $n is used.
+ * src/reader.c (symbol_should_be_used): Check midrule parent rule for
+ $n usage.
+ (packgram): Before invoking grammar_rule_check on any rule, make sure
+ all actions have already been scanned in order to set `used' flags.
+ Otherwise, checking that a midrule's $$ is set will not always work
+ properly because the midrule check must forward-reference the midrule's
+ parent rule.

+
+ Similar to the recently removed %before-header, add %code-top as the

+ * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
+ ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
+ gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
+ * src/Makefile.am (DEFS): Remove, since configmake does this for us.
+ (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
+ * src/system.h: Include inttypes.h unconditionally, now that we
+ use the inttypes module. Don't bother to include stdint.h, since
+ inttypes.h now does that for us.
+ (LOCALEDIR): Remove, now that we use the configmake module.
+ * src/getargs.c: Include configmake.h.
+ * src/main.c: Likewise.
+ * src/output.c: Likewise.
+ * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
+ not from $abs_top_builddir, since config.h moved.
+
+
+ Port to GCC 2.95. First two problems reported by Michael Deutschmann in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
+
+ * src/parse-gram.y (symbol_declaration): Don't put statements
+ before declarations; it's not portable to C89.
+ * src/scan-code.l (handle_action_at): Likewise.
+
+ * src/scan-code.l: Always initialize braces_level; the old code
+ left it uninitialized and therefore had undefined behavior.
+
+ Don't attempt to redefine 'assert', since it runs afoul of
+ systems where standard headers (mistakenly) include <assert.h>.
+ Instead, define and use our own alternative, called 'aver'.
+ * src/reader.c: Don't include assert.h, since we no longer
+ use assert.
+ * src/scan-code.l: Likewise.
+ * src/system.h (assert): Remove, replacing with....
+ (aver): New function, taking a bool arg. All uses changed.
+ * src/tables.c (pack_vector): Ensure that aver arg is bool,
+ not merely an integer.

+
+ * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
+ * data/c.m4 (YYPUSH): New.
+ (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
+ * src/getargs.c (push_parser): New var.
+ * src/getargs.h (push_parser): New declaration.
+ * src/output.c (prepare): Add macro insertion of `push_flag'.
+ * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
+ (prologue_declaration): Parse %push-parser.
+ * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
+ * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
+ list of removed lines from the traces observed.
+ (AT_CHECK_CALC_LALR): Added push parser tests.

+ * NEWS: Version 2.3a.
+ * configure.ac (AC_INIT): Likewise.
+
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
+ "#define YYSTYPE int" that caused "make maintainer-check" to fail
+ due to header ordering dependencies. I don't know why the #define
+ was there.
+
Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
runtime cost when YYDEBUG is not defined, and so that some tests
that used to fail now work. Problem and initial suggestion by
