On the contrary, it is important to remember that compilers are capable of performing transformations on the code in order to improve performance, but they aren’t capable of thinking.Compiler optimizationssave the developer from worrying about small inefficiencies, such as whether a multiplication ca...
参考论文Machine Learning in Compiler Optimization I. Introduction It is All About Optimization 编译器有两个任务:translation和optimization。translation是成功将程序翻译成可执行文件。optimization是找到最高效的翻译。 在之前,编译和机器学习是两个不交叠的领域,现在这两个领域结合在了一起。因为可以把代码看做一...
compile分成了front end, optimization, back end三个阶段(本文主要讲优化,和传统的脂粉前后端不一样)。front end主要做词法分析、语法分析;backend主要是code generation;optimization原本应属于back end,…
In Visual C++ .NET 2003, Whole Program Optimization (WPO) was not supported for builds using the /clr switch, but Visual C++ 2005 adds this capability for managed code. This feature enables cross-module optimization, which I'll discuss later in the article. The only class of optimizations ...

Likewise, if you’ve ever tried to improve your application’s performance using the Profile Guided Optimization (PGO) feature in Visual Studio, you were likely blind to whether your training data actually had the desired effect.To help with this, in Visual Studio 2013 we’ve done wor...

For example, theOptimizationproperty, by default, is set toMaximize Speed (/O2)in a Release configuration, but is disabled in the Debug configuration. You can always see and change the configuration and platform a property value should apply to. The following illustration shows the property pages...
it concluded that it’s safe to execute the multiplication and substitute the result (25). In the second optimization, the second call to the square function, square(m), has been inlined, as well. However, because the value of m isn’t known at compile time, the compiler can’t evalua...
