+
+ * 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

+ Paolo Bonzini.
+ * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
+ * data/glr.cc (b4_parser_class_name):

+2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.

+
+2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Whether the default %destructor/%printer applies to a particular symbol
+ isn't a question of whether the user *declares* that symbol (in %token,
+ for example). It's a question of whether the user by any means
+ *defines* the symbol at all (by simply using a char token, for
+ example). $end is defined by Bison whereas any other token with token
+ number 0 is defined by the user. The error token is always defined by
+ Bison regardless of whether the user declares it with %token, but we
+ may one day let the user define error as a nonterminal instead.
+ * NEWS (2.3+): Say "user-defined" instead of "user-declared".
+ * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
+ the meaning of "user-defined".
+ * tests/actions.at (Default %printer and %destructor for user-declared
+ end token): Rename to...
+ (Default %printer and %destructor for user-defined end token): ...
+ this.
+
+ * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
+ computation of whether to apply the default, don't maintain a list of
+ every Bison-defined symbol. Instead, just check for a first character
+ of '$', which a user symbol cannot have, and check for the error token.
+
+2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Don't apply the default %destructor or %printer to the error token,
+ $undefined, or $accept. This change fits the general rule that the
+ default %destructor and %printer are only for user-declared symbols,
+ and it solves several difficulties that are described in the new test
+ cases listed below.
+ * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
+ * tests/actions.at (Default %printer and %destructor are not for error
+ or $undefined, Default %printer and %destructor are not for $accept):
+ New test cases.
+
+2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Allow %start after the first rule.
+ * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
+ when parsing the first rule.
+ (check_and_convert_grammar): Search for it here after all grammar
+ declarations have been parsed. Skip midrules, which have dummy LHS
+ nonterminals.
+ * src/symtab.c (symbol_is_dummy): New function.

+
+ Redo some of the previous commit: add back the ability to use
+ non-aliased/undeclared string literals since it might be useful to
+ those declaring %token-table.
+ * src/reader.c (check_and_convert_grammar): Undo changes in previous
+ commit: don't worry about complaints from symbols_pack.
+ * src/symtab.c (symbol_new, symbol_class_set,
+ symbol_check_alias_consistency): Undo changes in previous commit: count
+ each string literal as a new symbol and token, assign it a symbol
+ number, and don't complain about non-aliased string literals.
+ (symbols_pack): Since symbol_make_alias still does not decrement symbol
+ and token counts but does still set aliased tokens to the same number,
+ symbol_pack_processor now leaves empty slots in the symbols array.
+ Remove those slots.
+ * tests/regression.at (Undeclared string literal): Remove test case
+ added in previous commit since non-aliased string literals are allowed
+ again.
+ (Characters Escapes, Web2c Actions): Undo changes in previous commit:
+ remove unnecessary string literal declarations.
+ * tests/sets.at (Firsts): Likewise.
+
+2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Don't allow an undeclared string literal, but allow a string literal to
+ be used before its declaration.
+ * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
+ symbols_pack complained.
+ * src/symtab.c (symbol_new): Don't count a string literal as a new
+ symbol.
+ (symbol_class_set): Don't count a string literal as a new token, and
+ don't assign it a symbol number since symbol_make_alias does that.
+ (symbol_make_alias): It's not necessary to decrement the symbol and
+ token counts anymore. Don't assume that an alias declaration occurs
+ before any uses of the identifier or string, and thus don't assert that
+ one of them has the highest symbol number so far.
+ (symbol_check_alias_consistency): Complain if there's a string literal
+ that wasn't declared as an alias.
+ (symbols_pack): Bail if symbol_check_alias_consistency failed since
+ symbol_pack asserts that every token has been assigned a symbol number
+ although undeclared string literals have not.
+ * tests/regression.at (String alias declared after use, Undeclared

+
+2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Handle string aliases for character tokens correctly.
+ * src/symtab.c (symbol_user_token_number_set): If the token has an
+ alias, check and set its alias's user token number instead of its own,
+ which is set to indicate the alias. Previously, every occurrence of
+ the character token in the grammar overwrote that alias indicator with
+ the character code.
+ * tests/input.at (String aliases for character tokens): New test.
+
+2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>

+
+ * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
+ to prevent failures when building on older platforms.
+ Check for autopoint failure.
+ Set XGETTEXT_OPTIONS to values that check for C format strings,
+ so that translators are warned about them (this also helps
+ prevent core dumps).
+
+ * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
+ function, since it simplifies our code a bit.
+
+ * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
+ rather than -W, so we don't get bogus warnings about sign comparisons.

+ Clean up scanners a bit.
+ * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack

+ scan-code-c.c, so get rid of them here.
+ * src/scan-gram.l: Likewise.
+ * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack

+ * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
+
+2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Suppress signed/unsigned comparison warnings for yycheck.
+ * data/c.m4 (b4_safest_int_type): New macro.

+ a signed int type, cast it to b4_safest_int_type first.
+ * data/yacc.c: Likewise.
+ (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is

+
+2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
+
+ * doc/bison.texinfo: Fix some typos.
+
+2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
+

+ po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
+
+ * bootstrap (gnulib_tool): Stop using --assume-autoconf;

+ (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
+ translation was patched, so stop omitting it.
+
+2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Enable declaration of default %printer/%destructor. Make the parser

+
+ Make the skeletons consistent in how they pop the end token and invoke

+ %destructor for the end token.
+ * data/lalr1.cc (yy::parser::parse): Don't check for the final state
+ until after shifting the end token, or else it won't be popped.
+ * data/yacc.c (yyparse): Likewise.
+
+ * data/glr.c (yyparse): Clear the lookahead after shifting it even when

+ even when it's the end token.
+ * data/lalr1.cc (yy::parser::parse): Likewise.
+ * data/yacc.c (yyparse): Likewise.
+
+ * src/reader.c (packgram): Don't check rule 0. This suppresses unused

+
+ * tests/actions.at (Printers and Destructors): Test all the above.
+
+2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ Update to latest gnulib and gettext versions.

+
+ Change %merge result type clash warnings to errors. Discussed at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
+ * src/reader.c (record_merge_function_type): Use complain_at.
+ * tests/glr-regression.at (Missed %merge type warnings when LHS type is
+ declared later): Update test case results.

+
+ * src/getargs.h, src/getargs.c: Swap --report and --trace handling
+ to be in alphabetical order.
+ (trace_args): Spelling fixes.

+
+ * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
+ so they don't collide with user-defined macros.
+ (yy_stack_print): Don't assume that yytype_int16 promotes to int;
+ this was never guaranteed, and now that we're using gnulib stdint,
+ which defines int_fast16_t to long int, the problem is exposed.
+
+2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/c.m4 (b4_basename): Simplify a bit, since we don't
+ need the full POSIX semantics (and weren't implementing them
+ anyway).
+
+ Adjust to Autoconf 2.60 and today's gnulib.
+ * bootstrap (gnulib_modules): Add stdint.
+ Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
+ no longer copies it.
+ (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
+ since stdint needs the former and wcwidth (which is now required
+ by mbswidth) needs the latter.
+ Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
+ work around a compatibility glitch between gettext 0.14.6 and
+ Autoconf 2.60.
+ * configure.ac (AC_PREREQ): Require Autoconf 2.60.
+ Do not check for uintptr_t, since new stdint module does the right
+ thing.
+ * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
+ Add stdint.h, stdint_.h, wcwidth.h.
+ * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
+ Add absolute-header.m4, double-slash-root.m4, longlong.m4,
+ stdint.m4, wchar_t.m4, wcwidth.m4.
+ * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
+ usual order for ../lib/*.h files.
+ (file_name_split): Use last_component, not base_name, to adjust
+ to gnulib changes.
+ * src/parse-gram.h: Include <strverscmp.h> in the usual order
+ for ../lib/*.h files.
+ (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
+ Define unconditionally, since we now assume the stdint module.
+ * src/scan-skel.l: Include <dirname.h>.
+ (BASE_QPUTS): Use last_component, not base_name.
+ * src/system.h: Include <unlocked-io.h> in the usual order
+ for ../lib/*.h files. Include <stdint.h> unconditionally,
+ since we now use the stdint module.
+ (uintptr_t): Declare if UINTPTR_MAX is not defined, not
+ HAVE_UINTPTR_T, since we now use the stdint module.
+ (base_name): Remove decl, since files now include <dirname.h>
+ to get the decl.
