问题描述

当您使用/optimize +编译器选项时，C#编译器会执行哪些优化?

What optimizations does the C# compiler perform when you use the /optimize+ compiler option?

推荐答案

据我所知，C#代码优化被简化为通用的CLI常见的代码优化.显然，这取决于CLI的版本.请参阅:
http://www.drdobbs.com/net-code-optimization/184416840 [ ^ ].

这是有关JIT优化的有趣的CodeProject文章: JIT优化 [

As far as I know, C# code optimization is reduced to the general code optimization common for CLI. Apparently, it depends on the version of CLI. Please see:
http://www.drdobbs.com/net-code-optimization/184416840[^].

This is an interesting CodeProject article on JIT optimization: JIT Optimizations[^].

有两个影响代码优化的C#编译器开关:/optimize和/debug.
下面将显示这些开关对C#编译器生成的IL代码的质量和JIT编译器生成的本机代码的质量的imapact.

编译器开关设置:说明
--------------------------------------
/optimize-/debug-:未优化"C#IL代码质量"，并且已优化"JIT本机代码质量".

/optimize-/debug(+/full/pdbonly):未优化"C#IL代码质量"，未优化"JIT本机代码质量".

/optimize +/debug(-/+/full/pdbonly):优化了"C#IL代码质量"，并且优化了"JIT本机代码质量".

There are two C# compiler switches that impact code optimization: /optimize and /debug.
The following will shows the imapact these switches have on the quality of the IL Code generated by the C# compiler and the quality of the native code generated by the JIT compiler

Compiler Switch Settings : Description
--------------------------------------
/optimize- /debug- : "C# IL code Quality" is UnOptimized and "JIT Native Code Quality" is optimized.

/optimize- /debug(+/full/pdbonly) : "C# IL code Quality" is UnOptimized and "JIT Native Code Quality" is Unoptimized.

/optimize+ /debug(-/+/full/pdbonly): "C# IL code Quality" is Optimized and "JIT Native Code Quality" is optimized.
