Browse Source 
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.

@@ -8,6 +8,14 @@ Changes in version 1.75a, 2002-10-24:
ago, but nobody noticed until we recently asked someone to try
building Bison with a K&R C compiler.
* %error-verbose
This new directive is preferred over YYERROR_VERBOSE.
* %lex-param, %parse-param
These new directives are preferred over PARSE_PARAM and LEX_PARAM.
In addition, they provide a means for yyerror to remain pure, and
to access to the current location.
Changes in version 1.75, 2002-10-14:
* Bison should now work on 64-bit hosts.
