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.
