是否.NET JIT优化空循环走？ [英] Does .NET JIT optimize empty loops away?

问题描述

这篇文章表明并非如此。但是，仍然需要评估的循环条件。请问java的只是采用特定的技巧认识到这一点呢？

This article suggests otherwise. But there is still a need to evaluate the loop condition. Does java just employ a specific trick to recognize this case?

推荐答案

查看跟进故事你引用的文章。

请注意，以人回答：它出现在OP是问有关.NET JIT，而不是Java JIT，因为引用的文章指出的Java做的（或只有Java的那样）优化空手循环做得更好

NOTE to people answering: It appears the OP is asking about the .NET JIT, not the Java JIT, since the article referenced suggested that Java did a better job of (or that only Java did) optimizing away empty loops.
