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.
Remove obsolete references to bison.simple and bison.hairy.
* src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL.
* src/parse-gram.y (declaration): Use enum "report_states".
* src/scan-skel.l ("@output ".*\n): Close any old yyout before new one.
using typedef instead of defining it as a macro. POSIX requires this.
For consistency, YYLTYPE is also declared instead of defined.
%union directives can now have a tag before the `{', e.g., the
directive `%union foo {...}' now generates the C code
`typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
The default union tag is `YYSTYPE', for compatibility with Solaris 9
Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
instead of `yyltype'.
`yystype' and `yyltype' are now obsolescent macros instead of being
typedefs or tags; they are no longer documented and will be
withdrawn in a future release.
since this causes problems when __file__ contains character
sequences like "@" that are treated specially by src/scan-skel.l.
Instead, just use the file's basename. This fixes the bug
reported by Martin Mokrejs in
<http://mail.gnu.org/pipermail/bug-bison/2002-December/001949.html>.
POSIX requires. Improve the quality of locations in Bison
diagnostics.
Remove duplicate decl of current_file.
Fix minor promotion problem in templates.
Fix Debian Bug 102878.
Avoid use of <assert.h>, as the GNU Coding Standards hint that one
should use `if (! x) abort ();' rather than `assert (x);', and
anyway it's one less thing to worry about configuring.
* data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
(YY_REDUCE_PRINT): New.
(yyparse): Use them.
* data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
YYDPRINT here.
(yyglrReduce, yyrecoverParseError, yyparse): Don't report the
state reached after the reduction/recovery, since...
(yyparse, yyprocessOneStack): Report the state we are entering in.
Add support for --trace=skeleton.
* src/scan-skel.l: %option debug.
Scan strings of non-@ or n instead of character by character.
(scan_skel): Handle trace_skeleton.
(QPUTS): New.
(@output_parser_name@, @output_header_name@): ``Restore'' their
support (used to be M4 macros).
* data/yacc.c: Quote larger chunks, a la glr.c.
* data/lalr1.cc: Likewise.
The header guards are no longer available, so use some other
string than `YYLSP_NEEDED'.
`yacc.c''s behavior as (possibly wrong) reference.
* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
instead of fprint on stdout.
Set and report the last_line of the symbols.
Consistently display values and locations.
