+
+	Adjust verbose message to using emacs.
+	* etc/bench.pl.in: Inform compilation-mode when we change the
+	directory.
+	(generate_grammar_list): Recognize %define "variant" in addition
+	to %define variant.
+
+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	Classify symbols by type-name.
+	* src/uniqstr.h (UNIQSTR_CMP): New.
+	* src/output.c (symbol_type_name_cmp, symbols_by_type_name)
+	(type_names_output): New.
+	(muscles_output): Use it.
+	* data/lalr1.cc (b4_symbol_action_): Remove.
+	(b4_symbol_case_, b4_type_action_): New.
+	Adjust uses of b4_symbol_action_ to use b4_type_action_.

+
+	Change the handling of the symbols in the skeletons.
+	Before we were using tables which lines were the symbols and which
+	columns were things like number, tag, type-name etc.  It is was
+	difficult to extend: each time a column was added, all the numbers had
+	to be updated (you asked for colon $2, not for "tag").  Also, it was
+	hard to filter these tables when only a subset of the symbols (say the
+	tokens, or the nterms, or the tokens that have and external number
+	*and* a type-name) was of interest.
+	
+	Now instead of monolithic tables, we define one macro per cell.  For
+	instance "b4_symbol(0, tag)" is a macro name which contents is
+	self-decriptive.  The macro "b4_symbol" provides easier access to
+	these cells.
+	
+	* src/output.c (type_names_output): Remove.
+	(symbol_numbers_output, symbol_definitions_output): New.
+	(muscles_output): Call them.
+	(prepare_symbols): Define b4_symbols_number.

+
+	--trace=muscles
+	* src/getargs.h, src/getargs.c (trace_muscle): New.
+	(trace_types, trace_args): Support it.
+	* src/output.c (output_skeleton): Use it.
+

+
+	muscles_output.
+	* src/output.c (muscles_output): New, extracted from...
+	(output_skeleton): here.
+	Adjust.

+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	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.
