Question

The .NET CLR JIT will; to my Understanding;tries to better code using patterns, such as Method Inlining,Loop Unrolling. 如果采用方法,则出于以下原因不能这样做:

Methods that are greater than 32 bytes of IL will not be inlined.
Virtual functions are not inlined.
Methods that have complex flow control will not be in-lined. Complex flow control is any flow control other than if/then/else; in this case, switch or while.
Methods that contain exception-handling blocks are not inlined, though methods that throw exceptions are still candidates for inlining.
If any of the method s formal arguments are structs, the method will not be inlined.
Etc...

我的问题是...... 是否有办法查明联合技术优化程序决定如何为这些或其他原因ski?

我认为,我想知道需要调整哪些法典领域,以确保我能够利用最佳联合技术。

现在,你可以自行操作<代码>。 CoreCLR,收集了你想要的所有统计数据。您可审查clrconfig Values.h,并使任何旗帜都能获得任何相关信息(例如,JitDump,使用快速指挥)。

这并非易事,而是可能的。
