associated with tokens.
* src/output.c (prepare_symbols): Don't escape strings,
since users don't want to see C escapes.
* tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
in diagnostics.
* tests/regression.at (Token definitions, Web2c Actions): Likewise.
translate strings.
* data/yacc.c (_) [!defined _]: New macro.
All English strings wrapped inside this macro.
* doc/bison.texinfo (Bison Parser): Document _.
* po/POTFILES.in: Include src/parse-gram.c, since it now
includes translateable strings that parse-gram.y doesn't.
alloca function (when available) to extend the parser stack, due
to widespread problems in unchecked stack-overflow detection.
* data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
responsibility to set it to a positive value. This lets the user
specify a value that is not a preprocessor constant.
* data/yacc.c (YYMAXDEPTH): Likewise.
(YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
* doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
to be a compile-time constant. However, explain the constraints on it.
Also, explain the constraints on YYINITDEPTH.
(Table of Symbols): Explain that alloca is no longer the default.
Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
to 1.
(error_): Rename as...
(error): this, since it is visible to the user.
Adjust callers.
(Parser::message): Now an automatic variable from...
(Parser::yyreport_syntax_error_): here.
* tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
Parser::error.
* tests/input.at: Escape $.
Introduce another definition to address simple location arrays.
(yyGLRStack): New member: yyerror_range.
(yyrecoverSyntaxError, yyparse): Update it.
(yyrecoverSyntaxError): Use it when shifting the error token to
have an accurate range, equivalent to the one computed by both
yacc.c and lalr1.cc.
* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
that column numbers start at column 0, as per GNU Coding
Standards, the others tests, and the doc.
(_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
Adjust to the above change (first column is 0).
And adjust the location of the "<error>", now covering the whole
line.
to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
bootstrapping problem reported by Matthias Klose; see
<http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
* src/conflicts.c (conflicts_print): Likewise.
* tests/conflicts.at (%expect not enough, %expect too much,
%expect with reduce conflicts): Likewise.
* doc/bison.texinfo (Expect Decl): Document this. Also mention
that the warning is enabled if the number of conflicts changes
(not necessarily increases).
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.
Fix copyright notice.
* tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
New.
* tests/actions.at, tests/calc.at, tests/conflicts.at,
* tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
* tests/regression.at, tests/torture.at: Use them for all the
grammars that are to be compiled.
* tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
* doc/bison.texinfo (GLR Parsers): Document `inline'.
defines it.
* data/glr.c (yystos): New.
(b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
(YYDSYMPRINT): New.
(yyval): Don't define it, it is handled via M4.
(yyrecoverParseError): Free verbosely the discarded symbols.
* data/yacc.c (yysymprint): Remove, rather...
(b4_yysymprint_generate): invoke.
* data/c.m4 (b4_yysymprint_generate): New.
Accept pointers as arguments, as opposed to the version from
yacc.c.
(b4_yydestruct_generate): Likewise.
* tests/cations.at (Printers and Destructors): Use Bison directives
instead of CPP macros.
Don't rely on internal details.
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.
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.
