+
+	Update the variant example.
+	* examples/variant.yy: Formatting changes.
+	One stage build.
+
+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	Support constructor with an argument.
+	This improves the "list" bench by 2%.
+	
+	* data/lalr1.cc (variant::build): Add an overloaded version with
+	an argument.
+	* tests/c++.at (AT_CHECK_VARIANT): Check it.
+
+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	Test variants.
+	* tests/c++.at (AT_CHECK_VARIANTS): New.
+	Use it with and without %define assert.
+
+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	Add %precedence support.
+	Unfortunately it is not possible to reuse the %prec directive.  This
+	is because to please POSIX, we do not require to end the rules with a
+	semicolon.  As a result,
+	
+	foo: bar %prec baz
+	
+	is ambiguous: either a rule which precedence is that of baz, or a rule,
+	and then a declaration of the precedence of the token baz.
+	
+	* doc/bison.texinfo: Document %precedence.
+	(Precedence Only): New.
+	* src/assoc.h, src/assoc.c (precedence_assoc): New.
+	* src/conflicts.c (resolve_sr_conflict): Support it.
+	* src/scan-gram.l, src/parse-gram.y (%precedence): New token.
+	Parse it.
+	* tests/calc.at: Use %precedence for NEG.
+	* tests/conflicts.at (%precedence does not suffice)
+	(%precedence suffices): New tests.
+
+2008-11-09  Akim Demaille  <demaille@gostai.com>
+
+	Make benches in a sub dirs.
+	* etc/bench.pl.in ($dir): New.
+	Use it.
+	Check the use of constructors with an argument.
+	(bench_variant_parser): Fix.
