+
+ Remove src/Makefile.am.
+ * src/Makefile.am: Rename as...
+ * src/local.mk: this.
+ Prefix all the paths with src/.
+ (AUTOMAKE_OPTIONS): Build object files in the sub dirs.
+ (AM_CPPFLAGS): Find find in builddir/src.
+ (YACC): Move the flags into...
+ (AM_YFLAGS): here.
+ * maint.mk (sc_tight_scope): Disable.
+ It used to bounce to the version in src/Makefile.am which is now
+ part of this very Makefile.
+ * Makefile.am, configure.ac: Adjust.
+ * src/scan-code-c.c, src/scan-code.l: We can no longer rely on
+ include "..." to find files "here": we are no longer in src/, so
+ qualify the includes with src/.
+ * doc/Makefile.am (PREPATH): No longer include the top_builddir
+ prefix.
+ (.x.1): Adjust to be able to create src/foo from the top level
+ Makefile, instead of going bounce to src/Makefile the creation of
+ foo.
+
+2008-11-15 Akim Demaille <demaille@gostai.com>
+
+ Remove useless variable.
+ * doc/Makefile.am (srcsrcdir): Remove.

+
+ Remove data/Makefile.am.
+ * data/Makefile.am: Rename as...

+ * etc/Makefile.am: Rename as...

+ Adjust.
+ * Makefile.am, configure.ac: Adjust.

+
+ Remove examples/local.mk.
+ examples/calc++/Makefile.am might be interesting to keep as is, since
+ it is an example in itself.
+
+ * examples/Makefile.am: Rename as...
+ * examples/local.mk: this.
+ Adjust.
+ * Makefile.am, configure.ac: Adjust.

+2008-11-15 Akim Demaille <demaille@gostai.com>
+
+ Remove build-aux/Makefile.am.
+ Recursive Makefiles are really way too slow, let's get rid of some of
+ them.
+
+ * build-aux/Makefile.am: Rename as...
+ * build-aux/local.mk: this.
+ Adjust paths.
+ * Makefile.am, configure.ac: Adjust.

+
+ Provide convenience constructors for locations and positions.
+ * data/location.cc (position::position): Accept file, line and
+ column as arguments with default values.
+ Always qualify initial line and column literals as unsigned.
+ (location::location): Provide convenience constructors.
+

+
+ Instead of using make_symbol<TOK_FOO>, generate make_FOO for each token type.
+ Using template buys us nothing, and makes it uselessly complex to
+ construct a symbol. Besides, it could not be generalized to other
+ languages, while make_FOO would work in C/Java etc.
+
+ * data/lalr1.cc (b4_symbol_): New.
+ (b4_symbol): Use it.
+ (b4_symbol_constructor_declaration_)
+ (b4_symbol_constructor_definition_): Instead of generating
+ specializations of an overloaded template function, just generate
+ several functions whose names are forged from the token names
+ without the token.prefix.
+ (b4_symbol_constructor_declarations): Generate them for all the
+ symbols, not just by class of symbol type, now that instead of
+ specializing a function template by the token, we generate a
+ function named after the token.
+ (b4_symbol_constructor_specialization_)
+ (b4_symbol_constructor_specializations): Remove.
+ * etc/bench.pl.in: Adjust to this new API.
+

+
+ %define token.prefix.
+ Provide a means to add a prefix to the name of the tokens as output in the
+ generated files. Because of name clashes, it is good to have such a
+ prefix such as TOK_ that protects from names such as EOF, FILE etc.
+ But it clutters the grammar itself.
+
+ * data/bison.m4 (token.prefix): Empty by default.
+ * data/c.m4 (b4_token_enum, b4_token_define): Use it.
+ * data/lalr1.cc (b4_symbol): Ditto.
+
+2008-11-13 Akim Demaille <demaille@gostai.com>
+
+ Compute at M4 time some of the subtractions.
+ * data/lalr1.cc (b4_substract): New.
+ (b4_rhs_data): Use it.
+
+2008-11-13 Akim Demaille <demaille@gostai.com>
+
+ symbol::token.
+ This is allows the user to get the type of a token return by
+ yylex.
+
+ * data/lalr1.cc (symbol::token): New.
+ (yytoknum_): Define when %define lex_symbol, independently of
+ %debug.
+ (yytoken_number_): Move into...
+ (symbol::token): here, since that's the only use.
+ The other one is YYPRINT which was not officially supported
+ by lalr1.cc, and anyway it did not work since YYPRINT uses this
+ array under a different name (yytoknum).
+
+2008-11-13 Akim Demaille <demaille@gostai.com>
+
+ YYERRCODE.
+ * TODO (YYERRCODE): Mention the case of $undef.

+ TODO: YYPRINT.
+ * TODO (YYPRINT): New.

+
+ Comment changes.
+ * data/lalr1.cc, data/yacc.c: Fix the description of the
+ yytranslate and yytoknum tables.
+

+
+ Define make_symbol in the header.
+ To reach good performances these functions should be inlined (yet this is
+ to measure precisely). To this end they must be available to the caller.
+
+ * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
+ location_type with the class name.
+ Since will now be output in the header, declare "inline".
+ No longer use b4_symbol_constructor_specializations, but
+ b4_symbol_constructor_definitions in the header.
+ Don't call it in the *.cc file.
+
+2008-11-13 Akim Demaille <demaille@gostai.com>
+
+ Define yytranslate in the header for lex_symbol.
+ * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
+ into the header file when using %define lex_symbol.
+ (yytranslate_): Declare inline.
+
+2008-11-13 Akim Demaille <demaille@gostai.com>
+
+ Define the constructors of symbol_type in b4_symbol_constructor_definitions.
+ The constructors are called by the make_symbol functions, which a
+ forthcoming patch will move elsewhere. Hence the interest of putting them
+ together.
+
+ The stack_symbol_type does not need to be moved, it is used only by the
+ parser.
+
+ * data/lalr1.cc: Move symbol_type and symbol_base_type
+ constructors into...
+ (b4_symbol_constructor_definitions): here.
+ Adjust.
+

Make it easier to move the definition of yytranslate_.
