(prepare_symbols): Quote tokens for M4.
(prepare): Don't insert output_infix, output_prefix,
output_parser_name, output_header_name; this is now down by scan-skel.
Insert skeleton as a C string.
(user_actions_output, symbol_destructors_output,
symbol_printers_output): Quote filenames for C and M4.
(b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
b4_output_header_suffix, b4_output_header_name, b4_header_guard):
Remove, since they couldn't handle arbitrary characters in file
names.
Remove use of "#ifdef b4_header_guard", since it
mishandled funny characters in file names, and anyway it isn't
needed any more.
(YYSTYPE_IS_TRIVIAL): Define when the .h file would.
(b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
b4_output_header_suffix, b4_output_header_name, b4_header_guard):
Remove, since they couldn't handle arbitrary characters in file
names.
Use YYSLP_NEEDED instead of b4_header_guard.
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001815.html>.
* data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
evaluate to 0 if it's impossible for NINF to be in the respective
table.
(yygetLRActions, yyrecoverParseError): Use them.
* src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
counted in the token inserted at end of file. Now takes
location_t *, not location_t, so that the location can be
adjusted. All uses changed.
* tests/regression.at (Invalid inputs): Adjust wording in
diagnostic to match the new behavior.
* tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
abort ();'. This reduces the runtime of the "Many lookaheads"
test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
GCC 3.2.
AT_DATA_LOOKAHEADS_GRAMMAR, AT_DATA_STACK_TORTURE): Replace `assert
(x);' with `if (! (x)) abort ();'. This reduces the runtime of the
"Many lookaheads" test from 27.6 to 2.7 minutes on a 440 MHz
Ultrasparc III.
All uses removed.
* src/scan-gram.l: Remove stack option. We no longer use the
stack, since the stack was never deeper than 1; instead, use the
new auto var c_context to record the stacked value.
Remove nounput option. At an unexpected end of file, we now unput
the minimal input necessary to end cleanly; this simplifies the
code.
Avoid unbounded token sizes where this is easy.
(unexpected_end_of_file): New function.
Use it to systematize the error message on unexpected EOF.
(last-string): Now auto, not static.
(YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
(scanner_last_string_free): Remove; not used.
(percent_percent_count): Move decl to just before use.
(SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
not the (never otherwised-used) CHARACTER.

yyerror can be variadic.
* data/yacc.c (b4_yyerror_args): New.
Use it when calling yyerror.
* data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
Use it when calling yyerror.
* doc/bison.texinfo (Error Reporting): Adjust.
* tests/calc.at (_AT_DATA_CALC_Y): Adjust.
* tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
Ideally, this should be done by m4_quotearg.
* src/scan-skel.l: Include quotearg.h.
Quote __ofile__.
* src/output.c (symbol_printers_output)
(symbol_destructors_output): Quote the file name.
Initialize to zero if the compiler is being picky.
(INITIAL): Clear braces_level instead of incrementing it.
(SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
as POSIX 1003.1-2001 requires.
and yyerror.
Have yyerror `use' its arguments.
* tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
returns true when location & yacc & pure & parse-param.
(_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
clashes.
* src/scan-gram.l: Use ['] instead of ['] to pacify
font-lock-mode.
Use complain_at.
Use quote, not quote_n since LOCATION_PRINT no longer uses the
slot 0.
Use consistent diagnostics for reporting type name clashes.
Quote the types with <>, for consistency with Yacc.
* tests/input.at (Type Clashes): Adjust to diagnostic changes.
New.
* data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
(b4_parse_param): Remove.
Use b4_identification.
Propagate b4_pure_args where needed to pass them to yyerror.
* data/glr.m4 (b4_parse_param): Remove.
(b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)
(b4_lpure_formals): New.
Use b4_identification.
(YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
b4_user_formals and b4_user_args.
(yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
(yyreportAmbiguity): When using a pure parser, also need
the location, and the parse-params.
Adjust callers.
(yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
When using a pure parser, also need the parse-params.
Adjust callers.
* tests/calc.at: Test pure (%pure-parser) and absolutely pure
(%pure-parser + %parse-param) LALR and GLR parsers.
(AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
(_AT_DATA_CALC_Y): Equip for purity of yyerror.
(_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
* tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
* doc/bison.texinfo: Untabify the whole file.
(Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
(Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
(Error Reporting): Adjust to these new directives.
Document %error-verbose, deprecate YYERROR_VERBOSE.
