* data/c++.m4 (b4_public_types_declare): Now define
symbol_type_base and symbol_type.
(b4_public_types_define): New.
In both cases, the definitions are taken verbatim from lalr1.cc.
* data/lalr1.cc: Adjust.
* data/c++.m4 (b4_semantic_type_declare): New.
Factors and generalizes what was in glr.cc and lalr1.cc.
* data/variant.hh (b4_semantic_type_declare): Redefine it for
variants.
* data/lalr1.cc, data/glr.cc: Use it.
* data/lalr1.cc: here.
There is no good reason to keep it private (and it is convenient
to use it from the scanner for instance). It is already public in
glr.cc.
The epilogue has its own ending \n, no need to add another.
* data/glr.c, data/lalr1.java, data/yacc.c: dnl when outputing the
epilogue.
* data/glr.cc: dnl when extending the epilogue.
Remove stray "private:".
This is a temporary band-aid until Bison gets proper alignment handling.
We need it on ARM.
* data/lalr1.cc (variant): Declare the buffer as a union to force
the same alignment as "long double".
Grep on Solaris does not support -q.
Reported by Summum Bonum.
* NEWS: Add a stub for 2.4.2.
* THANKS: Add Summum Bonum.
* tests/atlocal.in (EGREP): New.
(CC, CXX, XSLTPROC): Make it possible to override them via
envvars.
* tests/java.at: Use $EGREP instead of egrep.
Use AT_CHECK's ignore instead of grep's -q.
* TODO: Update.
* data/glr.c (yyreportSyntaxError): Use "switch" instead of
building the error message format dynamically.
* data/lalr1.java: Formatting changes.
* tests/local.mk: Replace "cd && testsuite" by "testsuite -C".
Solves problems when top_srcdir is an absolute path.
Suggested by Eric Blake.
* configure.ac: Require Autoconf 2.62.
* data/lalr1.cc: Comment changes.
* data/yacc.c (yysyntax_error): Rewrite, using a switch as in
lalr1.cc instead of building dynamically the format string.
* tests/local.at (AT_MATCHES_CHECK): New.
Based on Perl instead of Sed. Sed has too many portability
pitfalls, not ever Sed is GNU Sed.
* tests/actions.at (Fix user actions without a trailing semicolon):
Use it.
* data/java.m4 (b4_token_enum): Use the token.prefix.
* tests/local.at (AT_BISON_OPTION_PUSHDEFS): Define AT_TOKEN_PREFIX.
* tests/calc.at (_AT_DATA_CALC_Y): Use it.
Add checks for yacc.c, glr.c, lalr1.cc and glr.cc.
* tests/java.at: Comment changes.
(AT_CHECK_JAVA_MINIMAL): Define the END token.
(Java parser class and package names): Add token.prefix check.
* tests/local.mk (tests/atconfig): The rule was incorrect, but
remove it: now that there is no tests/Makefile.am, the top-level
Makefile properly updates atconfig when needed.
if it seems necessary.
* src/scan-code.l (flex rules section): Flag cpp directive from
any `#' to the first unescaped end-of-line. Semicolon is not
needed after `;', `{', '}', or cpp directives and is needed after
any other token (whitespaces and comments have no effect).
* tests/actions.at (Fix user actions without a trailing semicolon):
New test.
* tests/input.at (AT_CHECK_UNUSED_VALUES): Add semicolons to
to make user actions complete statements.
Adjust column numbers in error messages.
* tests/regression.at (Fix user actions without a trailing semicolon):
Remove. Covered by new test.
* tests/output.at (m4_expand): Don't override in newer autoconf,
where the underlying implementation changed.
* tests/cxx-type.at (_AT_RESOLVED_GLR_OUTPUT)
(_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT)
(_AT_AMBIG_GLR_OUTPUT_WITH_LOC, _AT_GLR_STDERR)
(_AT_VERBOSE_GLR_STDERR): Expand to double-quoted strings,
since some of them contain unbalanced ')'.
Signed-off-by: Eric Blake <ebb9@byu.net>
* data/bison.m4 (b4_symbol_action_location): New.
* data/c.m4 (b4_symbol_actions): Remove.
Adjust all callers to use by b4_symbol_foreach and the corresponding
b4_symbol_printer/destructor macro.
* data/glr.cc: Adjust.
* data/lalr1.java: Adjust the %destructor sanity check.
* src/output.c (symbol_code_props_output): Remove, we no longer
need the b4_symbol_printers/destructors tables.
Instead of defining complex list of tuples to define various properties of
the symbols, we now prefer to define symbols as "structs" in m4: using the
symbol key (its number), and the property name, b4_symbol gives it value.
Use this to handle destructors and printers.
* src/output.c (CODE_PROP): New.
(prepare_symbol_definitions): Use it to define the printer and
destructor related attributes of the symbols.
* data/lalr1.cc (b4_symbol_actions): Rename as...
(b4_symbol_action): this.
Use b4_symbol instead of 6 arguments.
(b4_symbol_printer, b4_symbol_destructor): New.
Use them instead of b4_symbol_actions.
The real problem is rather gnulib.mk, which itself is extracted from a
Makefile.am that gnulib expects to the "recursive". The tool
prefix-gnulib-mk converts such a gnulib.mk to be non-recursive. Also,
some AC_SUBST variables need to be adjusted.
* etc/prefix-gnulib-mk: New.
* bootstrap (slurp): Use it to convert further gnulib.mk.
* lib/Makefile.am: Rename as...
* lib/local.mk: this.
Adjust to be prefixed.
* Makefile.am, configure.ac: Adjust.
* src/local.mk (AM_CPPFLAGS): Extend it, don't define it.
* data/java.m4 (b4_typed_parser_table): Rename as...
(b4_typed_parser_table_define): this, for consistency.
Accept a comment as $4.
Move $2 into yy*_.
(b4_integral_parser_table): Rename as...
(b4_integral_parser_table_define): this.
* data/lalr1.java: Adjust all uses.
Use b4_parser_tables_define instead of generation by hand.
