+ POSIX: warn if %prec's token was not defined.
+ Reported by Florian Krohm at
+ <http://lists.gnu.org/archive/html/bug-bison/2009-12/msg00005.html>.
+ * NEWS (2.4.2): Document.
+ * src/reader.c (grammar_rule_check): Implement.
+ (grammar_current_rule_prec_set): Add comments explaining that we
+ here assume a %prec identifier is a token, but we still manage
+ to support POSIX.
+ * tests/input.at (%prec's token must be defined): New test
+ group.
+
+2009-12-31 Joel E. Denny <jdenny@clemson.edu>
+
+ * HACKING (Release Procedure): Recommend a secure automake.

+
+ Propagate i18n changes into glr.c.
+ * data/glr.c (yyreportSyntaxError): Use "switch" instead of
+ building the error message format dynamically.
+ * data/lalr1.java: Formatting changes.
+
+2009-12-22 Joel E. Denny <jdenny@clemson.edu>
+
+ Port small part of master's 11707b2b so future ports are easier.
+ * data/lalr1.java (YYParser::yysyntax_error): Untabify.
+
+2008-12-11 Akim Demaille <demaille@gostai.com>
+
+ Simplify the i18n of the error messages.
+ * data/lalr1.cc: Comment changes.
+
+2008-11-11 Akim Demaille <demaille@gostai.com>
+
+ Prefer M4 to CPP.
+ * data/lalr1.cc: Use b4_error_verbose_if instead of #if
+ YYERROR_VERBOSE.
+
+2008-11-11 Akim Demaille <demaille@gostai.com>
+
+ Support i18n of the parse error messages.
+ * TODO (lalr1.cc/I18n): Remove.
+ * data/lalr1.cc (yysyntax_error_): Support the translation of the
+ error messages, as done in yacc.c.
+ Stay within the yy* pseudo namespace.

+
+ Port small part of master's 8901f32e so future ports are easier.
+ * data/lalr1.cc (yy::parser::yysyntax_error_): Always add second
+ argument, but name it in the function definition only when
+ verbose error messages are enabled and it'll thus be used.
+ (yy::parser::parse): Update use of yysyntax_error_.
+

+
+ portability: `<' and `>' are not always defined on addresses.
+ Specifically, don't sort objects by their memory addresses when
+ they're not allocated in the same array or other object. Though
+ I haven't found a test case where that fails on my platform, C
+ says the behavior is undefined.
+ * src/AnnotationList.c (AnnotationList__insertInto): Remove
+ FIXME. Use new id field of InadequacyList nodes rather than
+ their memory addresses when sorting.
+ (AnnotationList__compute_from_inadequacies): Add
+ inadequacy_list_node_count argument to pass to
+ InadequacyList__new_conflict.
+ * src/AnnotationList.h
+ (AnnotationList__compute_from_inadequacies): Update prototype
+ and documentation for new argument.
+ * src/InadequacyList.c (InadequacyList__new_conflict): Add
+ node_count argument and use it to assign a unique ID.
+ * src/InadequacyList.h (InadequacyListNodeCount): New typedef.
+ (InadequacyList): Add id field.
+ (InadequacyList__new_conflict): Update prototype and
+ documentation for new argument.
+ * src/ielr.c (ielr_compute_annotation_lists): Update
+ AnnotationList__compute_from_inadequacies invocation.

+
+ Fix handling of yychar manipulation in user semantic actions.
+ The problem was that yacc.c didn't always update the yychar
+ translation afterwards. However, other skeletons appear to be
+ fine. glr.c appears to already translate yychar before every
+ use. lalr1.cc does not define yychar and does not document its
+ replacement, yyla, for users. It does provide yyclearin, but
+ that does not manipulate yyla and thus requires no translation
+ update. In lalr1.java, yychar is out of scope during semantic
+ actions.
+ * NEWS (2.5): Document.
+ * data/yacc.c (YYBACKUP): Don't bother translating yychar into
+ yytoken here.
+ (yyparse, yypush_parse): Instead, translate before every use of
+ yytoken, and add comments explaining this approach.
+ * tests/actions.at (Destroying lookahead assigned by semantic
+ action): New test group checking that translation happens before
+ lookahead destructor calls at parser return. Previously,
+ incorrect destructors were called.
+ * tests/conflicts.at (%error-verbose and consistent
+ errors): New test group checking that translation happens at
+ syntax error detection before the associated verbose error
+ message and the associated lookahead destructor calls. While
+ the destructor call is fixed by this patch, the verbose error
+ message is currently incorrect due to another bug (see
+ comments in test group), so this is an expected failure for now.

+
+ YYFAIL: warn about uses and remove from lalr1.java.
+ * NEWS (2.5): Document.
+ * data/lalr1.java (parser::YYStack::YYFAIL): Rename to YYERRLAB,
+ and make it private. Update all uses.
+ * src/scan-code.l (SC_RULE_ACTION): Implement warning.
+
+2009-12-21 Joel E. Denny <jdenny@clemson.edu>
+
+ YYFAIL: deprecate.
+ * NEWS (2.4.2): Document deprecation and the phase-out plan.
+ * data/lalr1.java (parser::YYStack::YYFAIL): Add comment about
+ deprecation.
+ * data/yacc.c (YYFAIL): Likewise, and suppress warnings about
+ YYFAIL from GCC cpp's -Wunused-macros.
+ * doc/bison.texinfo (Java Action Features): Remove YYFAIL
+ documentation.
+ (LocalWords): Remove YYFAIL.
+
+2009-12-17 Joel E. Denny <jdenny@clemson.edu>

+ Code cleanup.
+ * src/symtab.c, src/symtab.h (symbol_class_get_string): Remove

+ (WARN_CFLAGS_TEST): New substitution.
+ * data/glr.c: Avoid warning about __STRICT_ANSI__.

+
+ Simplify y.tab.c when location tracking is disabled.
+ * data/yacc.c: Do not check YYLTYPE_IS_TRIVIAL if location
+ tracking is not enabled. Instead, unconditionally define
+ YY_LOCATION_PRINT as a no-op for backward compatibility.

Avoid warnings from gcc -Wundef y.tab.c.
