Inlining code and Modules Subscribe More actions Dishaw__Jim Beginner 12-04-2006 08:06 PM 297 Views Assume that you have two modules A and B. Module A uses module B and calls subroutine foo in B. Is the optimizer able to inline foo? Can the optimizer inline foo if module B ...
He reinforced my bias in favor of uncompromising efficiency and inlining. 他加强了我对不牺牲效率和内联的偏爱. 互联网 Compiler optimizations such as aggressive inlining help reduce the code size and increase performance significantly. 编译器用诸如高度内联这样的优化帮助减小程序尺寸和显著提高效率. 互联网...
据电子邮件安全INKY的研究人员称，已经从英格兰和苏格兰员工的NHS电子邮件帐户发送出1000多条网络钓鱼邮件。
The various aspects enable the compiler to improve the performance of the generated code by aggressive inlining while carefully managing increases in compile time, thereby decreasing the power required to compile the code while increasing performance of the computing device. Thus, by inlining enough ...

Inlining can increase the size of the generated C/C++ code and reduce code readability. For example, suppose that you call a certain functionfoomany times in your source MATLAB®code. If the code generator always inlinesfoo, the generated code size increases becausefoois inlined every time it...
然而,inline函数背后的整体观念是,将“对此函数的每一个调用”都已函数本体替换之,这样做可能增加你的目标码(object code)大小。在内存有限的机器上,过度inline会造成程序体积太大,导致换页行为,降低缓存的命中率等一些带来效率损失的行为。 如果inline函数的本体很小,编译器针对“函数本体”所产生的码可能比针对“函...
JVM JIT编译器优化技术有近100中,其中最最重要的方式就是内联(inlining),即直接把方法代码插入到每次调用该方法的地方。方法内联可以省掉方法栈帧的创建,同时增加了CPU指令cache的命中率,方法内联还使让JIT编译器更多更深入的优化变成可能。我在fastxml(速度比XPP3(基于xmlpull)还快的xml解析器)开源项目中针对方法内...
Size of callee bytecode: 50 可以看到public AbstractStringBuilder append(String)这个方法稍大了一点,导致没有内联。这会导致多出一次方法栈,而这个方法可能在程序运行中调用频率很高,如果这个方法不能inlining,势必降低了性能。jdk的源码我们改不了,那我们可以选择不使用jdk的类,而是根据自己的实际场景写一个更简单...
