C ++托管代码编译器比C＃更快吗？ [英] Is C++ managed code compiler faster than C#?
问题描述
嗨新闻组
c ++编译器在执行时生成的代码比C＃
编译器更快吗？
c ++编译器比C＃编译器有更多的优化吗？
提前谢谢！
Hi newsgroup
Does the c++ compiler generate faster code at execution time than the C#
compiler?
Does the c++ compiler have more optimisations than the C# compiler?
Thanks in advance!
推荐答案
Henrik，
我不知道你会在C ++与C＃或VB中使用Managed
Extensions进行更好的代码优化。虽然每个编译器都会产生不同的IL，但是我不相信任何一个编译器会产生一些不同的东西，因为它会影响性能（然后，所有那些nop
VB编译器吐出的指令可能有问题。
希望这会有所帮助。

Henrik,
I don''t know that you will get better code optimization using Managed
Extensions in C++ versus C# or VB. While each compiler will produce
different IL, I don''t believe that any one compiler will produce something
so different as to affect performance (then again, all those nop
instructions that the VB compiler spits out can be a problem).
Hope this helps.

c ++编译器在执行时是否比C＃
编译器生成更快的代码？
c ++编译器的优化程度是否比C＃编译器更多？

嗯，你必须考虑C＃是专门为
而设计的..net框架，从而允许C＃编译器设计为吐出
'更好''（注意''）MSIL。
两个编译器的托管C ++ en VB.net有遗留问题
可能（可能，不会）导致质量较差的MSIL

Well, you have to consider that C# was designed specifically for the
..net framework, thus allowing the C# compiler to be designed to spit
out ''better'' (note the '') MSIL.
Both the compilers for managed C++ en VB.net have legacy issues that
might (might, not will) lead to lesser-quality MSIL

托管C ++和VB.net的编译器都存在遗留问题，可能（可能，不会）导致质量较差的MSIL
.net framework, thus allowing the C# compiler to be designed to spit

C＃专为框架设计的事实意味着什么。
您可以为.NET编写COBOL编译器（使用System.Reflection.Emit
命名空间）它比C＃编译器更有效率（从查看由C＃编译器生成的优化IL开始，只是
可以是唯一的东西）改进了它的堆栈用法。
The fact that C# was designed specifically for the framework means nothing.
You could write a COBOL compiler for .NET (using the System.Reflection.Emit
namespace) that''s even more efficient than the C# compiler (from looking at
the optimized IL produced by the C# compiler, just about the only thing that
can be improved is it''s usage of the stack).
