+ Finer input type for yytranslate.
+ This patch is debatable: the tradition expects yylex to return an int
+ which happens to correspond to token_number (which is an enum). This
+ allows for instance to return characters (such as '*' etc.). But this

+
+ Introduce make_symbol.
+ make_symbol provides a means to construct a full symbol (kind,
+ value, location) in a single shot. It is meant to be a Symbol
+ constructor, parameterized by the symbol kind so that overloading
+ would prevent incorrect kind/value pairs. Unfortunately
+ parameterized constructors do not work well in C++ (unless the
+ parameter also appears as an argument, which is not acceptable),
+ hence the use of a function instead of a constructor.

+
+ 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.

+ then the value of the std::string was correctly taken (i.e., the
+ lookahead was now an empty string), but std::string structure itself
+ was not reclaimed.
+
+ This is now done in variant::build(other&) (which is used to take the
+ value of the lookahead): other is not only stolen from its value, it
+ is also destroyed. This incurs a new performance penalty of a few
+ percent, and union becomes faster again.

+
+ Fuse the three stacks into a single one.
+
+ In order to make it easy to perform benchmarks to ensure that
+ there are no performance loss, lalr1.cc is forked into
+ lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
+ lalr1.cc.
+
+ Meanwhile, to make sure that lalr1-fusion.cc is correctly
+ exercized by the test suite, the user must install a symbolic link
+ from lalr1.cc to it.
+
+ Instead of having three stacks (state, value, location), use a
+ stack of triples. This considerably simplifies the code (and it
+ will be easier not to require locations as currently does the C++
+ parser), and also gives a 10% speedup according to
+ etc/bench (probably mainly since memory allocation is done once
+ instead of three times).
+
+ Another motivation is to make it easier to destruct properly
+ semantic values: now that they are bound to their state (hence
+ symbol type) it will be easier to call the appropriate destructor.
+
+ These changes should probably benefit the C parser too.
+
+ * data/lalr1.cc: Copy as...
+ * data/lalr1-fusion.cc: this new file.
+ (b4_rhs_value, b4_rhs_location): New definitions overriding those
+ from c++.m4.
+ (state_stack_type, semantic_stack_type, location_stack_type)
+ (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
+ (data_type, stack_type, yystack_): New.
+ (YYLLOC_DEFAULT, yypush_): Adjust.
+ (yyerror_range): Now based on data_type, not location_type.
+
+2008-11-03 Akim Demaille <demaille@gostai.com>
+
+ Push the state, value, and location at the same time.
+ This is needed to prepare a forthcoming patch that fuses the three
+ stacks into one.
+
+ * data/lalr1.cc (parser::yypush_): New.
+ (parser::yynewstate): Change the semantics: instead of arriving to
+ this label when value and location have been pushed, but yystate
+ is to be pushed on the state stack, now the three of them must
+ have been pushed before. yystate still must be the new state.
+ This allows to use yypush_ everywhere instead of individual
+ handling of the stacks.

+
+ Use variants to support objects as semantic values.
+ This patch was inspired by work by Michiel De Wilde. But he used
+ Boost variants which (i) requires Boost on the user side, (ii) is
+ slow, and (iii) has useless overhead (the parser knows the type of
+ the semantic value there is no reason to duplicate this
+ information as Boost.Variants do).
+
+ This implementation reserves a buffer large enough to store the
+ largest objects. yy::variant implements this buffer. It was
+ implemented with Quentin Hocquet.
+
+ * src/output.c (type_names_output): New.
+ (output_skeleton): Invoke it.
+ * data/c++.m4 (b4_variant_if): New.

+ (b4_char_sizeof, yy::variant): New.
+ (parser::parse): If variants are requested, define
+ parser::union_type, parser::variant, change the definition of
+ semantic_type, construct $$ before running the user action instead
+ of performing a default $$ = $1.
+ * examples/variant.yy: New.
+ Based on an example by Michiel De Wilde.
