* data/lalr1.cc (b4_tables_map): Move to...
* data/bison.m4: here.
Update the comment for yytable during the flight.
(b4_tables_declare, b4_tables_define): New.
* data/lalr1.cc: Use them.
* data/c.m4 (b4_table_define): New.
* data/yacc.c: Use b4_tables_define instead of output the tables
by hand.
* tests/regression.at (Web2c Actions): Adjust the expected output,
the order of the tables changed.
These tables are no longer needed in the parsers, and they don't seem to
be useful. They are not documented either.
* src/output.c (prepare_rules): Get rid of rhs and prhs.
Adjust the computation of (yy)r2.
TESTSUITEFLAGS is barely readable.
* tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
for backward compatibility.
Use the former instead of the latter.
They were used to get the symbol types, given a rule number, when
displaying the top of the stack before a reduction. But the symbol type
is available from the state stack. This has two be benefits: two tables
less in the parser (making it smaller), and a more consistent use of the
three stacks which will help to fuse them.
* data/yacc.c (yyprhs, yyrhs): Remove.
(YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
(yy_reduce_print): Take yyssp as argument.
Use it, together with yystos, to get the symbol type.
* tests/regression.at (Web2c Report): Remove these tables from the
expected output.
The point is to factor the generation of the tables across skeletons.
This is language dependant.
* data/c.m4 (b4_comment_): New.
Should be usable to define how to generate tables independently of
the language.
(b4_c_comment): New.
(b4_comment): Bounce to b4_c_comment.
Now support $2 = [PREFIX] for indentation.
* data/lalr1.cc (b4_table_declare): Don't output a comment if
there is no comment.
Indent it properly when there is one.
Output the ending semicolon.
(b4_table_define): Space changes.
Output the ending semicolon.
(b4_tables_map): New.
Use it twice instead of declaring and defining the (integral)
tables by hand.
* data/lalr1.cc (b4_table_declare): New.
Use it to declare the tables defined with b4_table_define.
(b4_table_define): Declare a third arg to match b4_table_declare
signature.
Move all the comments around invocations of b4_table_define into
the invocations itselves.
Move things around to have the order for declarations and
definitions.
* doc/bison.texinfo (-g, -x): Add space before argument.
(Option Cross Key): Implement FIXME: listing directives also.
* build-aux/cross-options.pl: Read from <STDIN> rather than <>.
(Short Option): Special case -d. Put arguments inside @option.
(Bison Directive): Add column, automatically extracted from
src/scan-gram.l (actual name passed as the first argument)
with special case for %define.
* doc/local.mk (doc/cross-options.texi): Pass src/scan-gram.l
to build-aux/cross-options.pl.
* src/getargs.c (usage): Document limitations of cross-options.pl.
* src/scan-gram.l: Likewise.
Reported by Csaba Raduly at
<http://lists.gnu.org/archive/html/bug-bison/2008-11/msg00048.html>.
* THANKS (Csaba Raduly): Add.
* data/glr.c: Fix overquoting on b4_prefix for yylval and yylloc.
* tests/calc.at (_AT_DATA_CALC_Y): If %defines is specified, generate
lexer in a separate module that includes the defines file.
(AT_CHECK_CALC): From AT_FULL_COMPILE, request compilation of lexer
source.
* tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Push AT_DEFINES_IF.
Adjust AT_LOC and AT_VAL to use AT_NAME_PREFIX.
(AT_BISON_OPTION_POPDEFS): Pop AT_DEFINES_IF.
(AT_DATA_SOURCE_PROLOGUE): New.
(AT_DATA_GRAMMAR_PROLOGUE): Use AT_DATA_SOURCE_PROLOGUE.
(AT_DATA_SOURCE): New.
(AT_FULL_COMPILE): Extend to support an additional source file.
* data/lalr1.cc (b4_subtract): Move to...
* data/bison.m4: here.
* data/glr.c (b4_rhs_data): Use it.
* data/yacc.c (b4_rhs_value, b4_rhs_location): Use it.
* doc/bison.texinfo: Synchronize ``Detail Node Listing''.
Align menus. Adjust word wrapping. Use node names for menu names.
(Examples): Don't abbreviate node names.
(LocalWords): Remove abbreviations.
(Copying): Make description a sentence.
(Java Action Features): Remove period to match the rest of menu.
* src/getargs.c (command_line_location): Set parameters to void.
* src/output.c (symbol_type_name_cmp): Make static.
(symbols_by_type_name): Set parameters to void.
(symbol_definitions_output): Remove unused parameter. Rename as...
(prepare_symbol_definitions): this.
(muscles_output): Move symbol_definitions_output to...
(output): here as prepare_symbol_definitions.
* tests/c++.at (AT_CHECK_VARIANTS): Remove unused parameters of main.
(AT_CHECK_NAMESPACE): Make unused parameter lloc unnamed.
There are two issues to handle: first scanning nested angle bracket pairs
to support types such as std::pair< std::string, std::list<std::string> > >.
Another issue is to address idiosyncracies of C++: do not glue two closing
angle brackets together (otherwise it's operator>>), and avoid sticking
blindly a TYPE to the opening <, as it can result in '<:' which is a
digraph for '['.
* src/scan-gram.l (brace_level): Rename as...
(nesting): this.
(SC_TAG): New.
Implement support for complex tags.
(tag): Accept \n, but not <.
* data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)
(b4_symbol_variant): Leave space around types as parameters.
* examples/variant.yy: Use nested template types and leading ::.
* src/parse-gram.y (TYPE, TYPE_TAG_ANY, TYPE_TAG_NONE, type.opt):
Rename as...
(TAG, TAG_ANY, TAG_NONE, tag.opt): these.
* tests/c++.at: Test parametric types.
This is not sufficient, but we test at least that the make_SYMBOL
interface is not affected by token.prefix. A more general test
will be implemented when the support of token.prefix is generalized
to more skeletons.
* tests/c++.at: One more variant test, using token.prefix.
* tests/Makefile.am: Rename as...
* tests/local.mk: this.
* Makefile.am, configure.ac: Adjust.
* Makefile.am (DISTCLEANFILES): Define.
(maintainer-check, maintainer-xml-check, maintainer-push-check):
Remove, we no longer need to bounce to the real targets.
It does not work, and I don't know how it was supposed to work: it seems
to be looking for sources in the build tree. I just moved it at a better
place, fixing it is still required.
* src/local.mk (echo): Remove.
(sc_tight_scope): Move to...
* maint.mk: here.
