Larger types otherwise. ** YYNOCODE is a number of type YYCODETYPE that is not used for ** any terminal or nonterminal symbol. ** YYFALLBACK If defined, this indicates that one or more tokens ** (also known as: "terminal symbols") have fall-back ** values which should be used if the original symbol ** would not parse. This permits keywords to sometimes ** be used as identifiers, for example. ** YYACTIONTYPE is the data type used for "action codes" - numbers ** that indicate what to do in response to the next ** token. ** NewParseTOKENTYPE is the data type used for minor type for terminal ** symbols. Background: A "minor type" is a semantic ** value associated with a terminal or non-terminal ** symbols. For example, for an "ID" terminal symbol, ** the minor type might be the name of the identifier. ** Each non-terminal can have a different minor type. ** Terminal symbols all have the same minor type, though. ** This macros defines the minor type for terminal ** symbols. ** YYMINORTYPE is the data type used for all minor types. ** This is typically a union of many types, one of ** which is NewParseTOKENTYPE. The entry in the union ** for terminal symbols is called "yy0". ** YYSTACKDEPTH is the maximum depth of the parser's stack. If ** zero the stack is dynamically sized using realloc() ** NewParseARG_SDECL A static variable declaration for the %extra_argument ** NewParseARG_PDECL A parameter declaration for the %extra_argument ** NewParseARG_PARAM Code to pass %extra_argument as a subroutine parameter ** NewParseARG_STORE Code to store %extra_argument into yypParser ** NewParseARG_FETCH Code to extract %extra_argument from yypParser ** NewParseCTX_* As NewParseARG_ except for %extra_context ** YYERRORSYMBOL is the code number of the error symbol. If not ** defined, then do no error processing. ** YYNSTATE the combined number of states. ** YYNRULE the number of rules in the grammar ** YYNTOKEN Number of terminal symbols ** YY_MAX_SHIFT Maximum value for shift actions ** YY_MIN_SHIFTREDUCE Minimum value for shift-reduce actions ** YY_MAX_SHIFTREDUCE Maximum value for shift-reduce actions ** YY_ERROR_ACTION The yy_action[] code for syntax error ** YY_ACCEPT_ACTION The yy_action[] code for accept ** YY_NO_ACTION The yy_action[] code for no-op ** YY_MIN_REDUCE Minimum value for reduce actions ** YY_MAX_REDUCE Maximum value for reduce actions */ #ifndef INTERFACE # define INTERFACE 1 #endif /************* Begin control #defines *****************************************/ #define YYCODETYPE unsigned char #define YYNOCODE 125 #define YYACTIONTYPE unsigned short int #define NewParseTOKENTYPE SToken typedef union { int yyinit; NewParseTOKENTYPE yy0; EOperatorType yy40; EFillMode yy44; SToken yy79; ENullOrder yy107; EJoinType yy162; SNodeList* yy174; EOrder yy188; SNode* yy212; bool yy237; } YYMINORTYPE; #ifndef YYSTACKDEPTH #define YYSTACKDEPTH 100 #endif #define NewParseARG_SDECL SAstCreateContext* pCxt ; #define NewParseARG_PDECL , SAstCreateContext* pCxt #define NewParseARG_PARAM ,pCxt #define NewParseARG_FETCH SAstCreateContext* pCxt =yypParser->pCxt ; #define NewParseARG_STORE yypParser->pCxt =pCxt ; #define NewParseCTX_SDECL #define NewParseCTX_PDECL #define NewParseCTX_PARAM #define NewParseCTX_FETCH #define NewParseCTX_STORE #define YYNSTATE 149 #define YYNRULE 135 #define YYNTOKEN 73 #define YY_MAX_SHIFT 148 #define YY_MIN_SHIFTREDUCE 245 #define YY_MAX_SHIFTREDUCE 379 #define YY_ERROR_ACTION 380 #define YY_ACCEPT_ACTION 381 #define YY_NO_ACTION 382 #define YY_MIN_REDUCE 383 #define YY_MAX_REDUCE 517 /************* End control #defines *******************************************/ #define YY_NLOOKAHEAD ((int)(sizeof(yy_lookahead)/sizeof(yy_lookahead[0]))) /* Define the yytestcase() macro to be a no-op if is not already defined ** otherwise. ** ** Applications can choose to define yytestcase() in the %include section ** to a macro that can assist in verifying code coverage.
