YYERROR is fine as it does not invoke this 1066 function. 1067 - If this state is a consistent state with a default action, then 1068 the only way this function was invoked is if the default action 1069 is an error action. In that case, don't check for expected 1070 tokens because there are none. 1071 - The only way there can be no lookahead present (in yychar) is if 1072 this state is a consistent state with a default action. Thus, 1073 detecting the absence of a lookahead is sufficient to determine 1074 that there is no unexpected or expected token to report. In that 1075 case, just report a simple "syntax error". 1076 - Don't assume there isn't a lookahead just because this state is a 1077 consistent state with a default action. There might have been a 1078 previous inconsistent state, consistent state with a non-default 1079 action, or user semantic action that manipulated yychar. 1080 - Of course, the expected token list depends on states to have 1081 correct lookahead information, and it depends on the parser not 1082 to perform extra reductions after fetching a lookahead from the 1083 scanner and before detecting a syntax error. Thus, state merging 1084 (from LALR or IELR) and default reductions corrupt the expected 1085 token list. However, the list is correct for canonical LR with 1086 one exception: it will still contain any token that will not be 1087 accepted due to an error action in a later state. 1088 */ 1089 if (yytoken != YYEMPTY) 1090 { 1091 int yyn = yypact[*yyssp]; 1092 yyarg[yycount++] = yytname[yytoken]; 1093 if (!yypact_value_is_default (yyn)) 1094 { 1095 /* Start YYX at -YYN if negative to avoid negative indexes in 1096 YYCHECK.
