We take the 2903 approach of translating immediately before every use of yytoken. 2904 One alternative is translating here after every semantic action, 2905 but that translation would be missed if the semantic action invokes 2906 YYABORT, YYACCEPT, or YYERROR immediately after altering yychar or 2907 if it invokes YYBACKUP. In the case of YYABORT or YYACCEPT, an 2908 incorrect destructor might then be invoked immediately. In the 2909 case of YYERROR or YYBACKUP, subsequent parser actions might lead 2910 to an incorrect destructor call or verbose syntax error message 2911 before the lookahead is translated. */ 2912 YY_SYMBOL_PRINT ("-> $$ =", yyr1[yyn], &yyval, &yyloc); 2913 2914 YYPOPSTACK (yylen); 2915 yylen = 0; 2916 YY_STACK_PRINT (yyss, yyssp); 2917 2918 *++yyvsp = yyval; 2919 *++yylsp = yyloc; 2920 2921 /* Now `shift' the result of the reduction.
