記住：我們不能寄希望於我們的代碼會總是運行在會轉換尾遞歸調用的jvm上。Can your jit transform tail recursion on code while preserving language semantics
清單4 .您的jit會在保持語言語義的同時轉換尾遞歸代碼嗎？So, as the example in listing 3 shows, we cannot expect static compilers to perform transformation of tail recursion on java code while preserving the semantics of the language
因此，如清單3中的示例所示，我們不能期望靜態編譯器會在保持語言語義的同時對java代碼執行尾遞歸轉換。He shows why this matters and offers a bit of code to help you determine whether your just - in - time compiler can transform tail recursion on code while preserving semantics

由於avs標準中的2d - vlc演算法使用了多碼表切換以及escape碼等技術，所以針對avs標準的特點對演算法進行了面向多碼表切換以及escape碼處理的修改，推導出了適用於avs標準的遞歸公式並統計了修改後pcbe編碼器的碼表，然後在avs標準的參考軟體中實現了本演算法。Therefore, to guarantee reasonable performance across jvms, you should always try to write code that most naturally fits a tail - recursive pattern in an iterative style instead
