Hi, my usage is yielding me a block like this: ---------
/*---------------------------------------------------. | yyerrorlab -- error raised explicitly by YYERROR. | `---------------------------------------------------*/ yyerrorlab: /* Pacify compilers like GCC when the user code never invokes YYERROR and the label yyerrorlab therefore never appears in user code. */ if (/*CONSTCOND*/ 0) goto yyerrorlab; /* Do not reclaim the symbols of the rule whose action triggered this YYERROR. */ YYPOPSTACK (yylen); yylen = 0; YY_STACK_PRINT (yyss, yyssp); yystate = *yyssp; goto yyerrlab1; --------- There, the `goto yyerrorlab;` line is annotated by this Xcode message: "Semantic Issue: Code will never be executed: _____.tab.c: Silence by adding parentheses to mark code as explicitly dead". The comment is really clear and I think I know what is happening and what I might be doing wrong. However, just to let you know that Xcode proposes some fix. If chosen, then the line: if (/*CONSTCOND*/ 0) turns to: if (/*CONSTCOND*/ /* DISABLES CODE */ (0)) So telling you, in case you wanted to change the line permanently in your sources. I don’t normally code C/C++, so please forgive me if I overlooked something! _______________________________________________ help-bison@gnu.org https://lists.gnu.org/mailman/listinfo/help-bison
