当编译器或解释器在静态分析代码时发现某些代码块无法被执行到,通常会给出警告或错误信息,指出存在“unreachable code”。 在return语句后出现“unreachable code”的情况很常见,因为return语句会终止当前函数的执行,并将控制权返回给函数的调用者。因此,任何位于return语句之后的代码都将成为“unreachable code”,因为在正...
你的return语句后面还有其他语句。return后面的语句是不会执行的。所以检测报错了。

First, break and continue may have labels and thus might not actually create dead code after them. For these we just assume if there is a label the following statements are still alive (line 21). Second, if blocks and labeled blocks can create problems with the analysis, we avoid ...
Spot the error? return is parsed as a complete statement with an unreachable expression-statement after it. Really. Luckily, Swift's static typing should exclude this and most related cases. Brief aside: It is possible to have legally unreachable code in Java, but that code has to be an ex...
CALLstatements that do not return to the calling program can result in results that are not correct. Statements after aCALLstatement are not marked as unreachable. Unreachable code is reported on a per line basis. If a line contains both code that is reachable and code that is unreachable, ...
because the statementx=3;is not reachable; but the superficially similar case: if (false) { x=3; } does not result in a compile-time error. An optimizing compiler may realize that the statementx=3;will never be executed and may choose to omit the code for that statement from the gener...
Description There appears to be an odd issue with the minification process. An extra return statement is causing "unreachable code after return statement," reported to me at video.min.js:38:146220 You can find it here: http://vjs.zencdn...
