* tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
* tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
This new file.
* tests/calc.at (AT_CHECK_CALC): Adjust.
* tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
(AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
* tests/local.at: here.
(AT_COMPILE_CXX): Tags the tests using it as c++.
Ignore the test if CXX is not functional.
into yylex, as SC_EPILOGUE is activated *before* the corresponding
yylex invocation. An alternative would be making it static, but
then it starts with the second %%'s beginning, instead of its end.
Remove Sequent/Pyramid discussion (nobody uses them any more).
Merge VMS and MS-DOS discussion; these ports may well be dead
but let's keep mentioning them for now. Put <> around email
addresses. Add copyright notice.
before initial_columns.
(location.hh): Use consistent variable names when defining the
operator<<.
Use "last" so that we subtract from Positions, not from unsigned.
AT_YACC_IF.
Redefine AT_YYERROR_SEES_LOC_IF using it.
(_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
not defined.
Don't use the location in yy::Parser::error_ and
yy::Parser::print_ when not %locations.
Activate more lalr1.cc tests.
error recovery, mixing with/without pops and discarding of the
lookahead.
Exercise YYERROR.
Disable the lalr1.cc tests as currently it doesn't support YYERROR.
Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
<http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
* data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
Check for malloc failure, for consistency with yacc.c.
(yytname_size): Remove, for consistency with yacc.c.
The bug still remains in data/lalr1.cc, as I didn't have time
to fix it there.
(CXX): this, to keep the original Autoconf semantics.
Require 2.57.
* data/lalr1.cc: Fix b4_copyright invocations.
If YYDEBUG is not defined, don't depend upon name_ being defined.
(location.hh): Include string and iostream.
(Position::filename): New member.
(Position::Position ()): New.
(operator<< (Position)): New.
(operator- (Position, int)): New.
(Location::first, Location::last): Rename as...
(Location::begin, Location::end): these, to mock the conventional
iterator names.
(operator<< (Location)): New.
* tests/atlocal.in (CXX): New.
* tests/testsuite.at (AT_COMPILE_CXX): New.
* tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
locations in a more synthetic way.
(AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
lalr1.cc is used.
Adjust the C locations to match those from Emacs: first column is
column 0.
Change all the expected results.
Conform to the GCS: simplify the locations when applicable.
(LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
(LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
these CPP macros with the m4 macros new defined by...
(AT_CHECK_PUSHDEFS): this, i.e.:
(AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
(AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALSm AT_LEX_PRE_ARGS)
New macros.
(AT_CHECK_POPDEFS): Undefine them.
(AT_CHECK_CALC_LALR1_CC): New.
Use it for the first lalr1.cc test.
Changes in response to error report by S. Eken: GLR mode does not
(yyfill): New function to copy from stack tree into array
(yyuserAction): Modify to allow incremental move of semantic values
to rhs array when in GLR mode.
Define YYFILL to use in user-defined actions to fill semantic array
(yyresolveStates): Use X == NULL for pointers, not !X.

* data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
when the stacks contain one element, as the loop would otherwise
free the last state, and then use the top state (the one we just
popped). This means that the initial elements will not be freed
explicitly, as is the case in yacc.c; it is not a problem, as
these elements have fake values.
