問題：
Presuming that your C++ compiler supports them, is there any particular reason not to use __FILE__ , __LINE__ and __FUNCTION__ for logging and debugging purposes?假設您的 C++ 編譯器支持它們，是否有任何特殊原因不使用__FILE__ 、 __LINE__和__FUNCTION__進行日誌記錄和調試？
I'm primarily concerned with giving the user misleading data—for example, reporting the incorrect line number or function as a result of optimization—or taking a performance hit as a result.我主要關心的是向用戶提供誤導性數據——例如，報告不正確的行號或作爲優化結果的函數——或者因此而導致性能下降。
Basically, can I trust __FILE__ , __LINE__ and __FUNCTION__ to always do the right thing?基本上，我可以相信__FILE__ 、 __LINE__和__FUNCTION__總是做正確的事嗎？
