+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	Update TODO.
+	* TODO (-D): is implemented.
+	(associativity): Same precedence must have the same associativity.
+	For instance, how can a * b / c be parsed if * is %left and / is
+	%right?
+	(YYERRORCODE, YYFAIL, YYBACKUP): New.
+
+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	Formatting changes.
+
+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	More information about the symbols.
+	* src/output.c (type_names_output): Document all the symbols,
+	including those that don't have a type-name.
+	(symbol_definitions_output): Define "is_token" and
+	"has_type_name".
+	* data/lalr1.cc (b4_type_action_): Skip symbols that have an empty
+	type-name, now that they are defined too in b4_type_names.

+
+	Regen.
+
+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	Make parser::yytranslate static.
+	Small speedup (1%) on the list grammar.  And makes yytranslate_ available
+	in non member functions.
+	
+	* data/lalr1.cc (yytranslate_): Does not need to be a instance
+	function.
+
+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	Avoid trailing spaces.
+	* data/c.m4: b4_comment(TEXT): Don't indent empty lines.
+	* data/lalr1.cc: Don't indent before rule and symbol actions, as
+	they can be empty, and anyway this incorrectly indents the first
+	action.

+	Comment changes.
+
+2008-11-10  Akim Demaille  <demaille@gostai.com>
+
+	Use "enum" for integral constants.
+	This is just nicer to read, I observed no speedup.
+	
+	* data/lalr1.cc (yyeof_, yylast_, yynnts_, yyempty_, yyfinal_)
+	(yterror_, yyerrcode_, yyntokens_): Define as members of an enum.
+	(yyuser_token_number_max_, yyundef_token_): Move into...
+	(yytranslate_): here.
+

+
+	Shortcuts in bench directives.
+	* etc/bench.pl.in (parse_dirs): New.
+	Use it.
+	(bench_variant_parser, bench_fusion_parser): Use %s and %d.
+	Create the benches in "benches/".

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