2

The goal is either to avoid the JIT compiler's run-time performance or memory cost or to avoid the interpreter's early performance overhead .

目的在于避免 JIT 编译器的运行时性能消耗或内存消耗，或者避免解释程序的早期性能开销。

3

This helps ensure that the options you think are being set are actually being received and recognized by the JIT compiler.

这可以帮助确保您考虑的正在设置的选项实际上都正被 JIT 编译器接受和识别。

4

Displays the total number of methods JIT -compiled since the application started .

显示自应用程序启动后实时（JIT ）编译的方法的总数。

5

This code causes a set of classes to be loaded and the methods of those classes all to be compiled by the JIT compiler.

这段代码将使 JIT 编译器加载一组类并编译所有这些类的方法。

6

Displays the peak number of methods the JIT compiler has failed to compile since the application started .

显示自应用程序启动后 JIT 编译器未能编译的方法的峰值数目。

7

A method that has been AOT-compiled may also be JIT-compiled if it meets the necessary recompilation criteria .

对于已经 AOT 编译的方法，如果它满足必要的重新编译条件，就可能再执行 JIT 编译。

9

This counter is updated at the end of every JIT compilation phase .

在每一 JIT 编译阶段的结尾更新此计数器。

10

The JIT compiler ensures it does not compile the MSIL at two different sequence points into a single native instruction .

JIT 编译器可确保不会将两个不同序列点的 MSIL 编译成一条本机指令。

12

Displays the total MSIL bytes JIT -compiled since the application started .

显示自应用程序启动后实时编译的总 MSIL 字节数。

13

The AOT-compiled code is the equivalent to the native code the JIT compiler would generate if it used a fixed optimisation level .

如果 JIT 使用了一种固定的优化级别，那么 AOT 编译的代码就等同于 JIT 编译器生成的本地代码。

14

For this reason , JIT compilers do not compile all code with the same degree of optimization .

因此，JIT 编译器不会使用相同的优化度来编译所有的代码。

16

Some of the highlights of the release are the JIT that's now on by default and an overhauled compiler and parser .

其中的一些亮点包括默认开启 JIT 和一个全面修正过的编译器及解析器。

17

Instruction generation can also be tailored to the underlying processor to take full advantage of the underlying platform .

JIT 编译器会根据处理器生成指令并充分利用所处的平台。

18

JIT compilers are allowed to take some liberties with synchronized blocks to reduce their performance cost .

JIT 编译器可以随意变动同步锁，以减少它们的性能成本。

19

In fact , most modern JIT compilers also support recompiling methods that are found to be very hot .

事实上，大部分现代的 JIT 编译器也支持重编译被认为是热方法的方法。

20

More importantly , the code generated by the JIT compiler is bound to the process that triggered the compilation .

更为重要的是，由 JIT 编译器生成的代码会绑定到触发编译的进程上。

22

Enabling this MDA allows you to determine which function is being JIT-compiled .

使用此 MDA ，您可以确定哪个函数正在进行 JIT 编译。

23

If you use codeCache with normal execution , it will only save off the compiled method bodies that get hot enough to JIT .

如果是在普通执行中使用 codeCache ，它只会保存那些足以 JIT 的经过编译的方法体。

24

By design , the Compiler class does nothing; it serves as a placeholder for a JIT compiler implementation .

设计中，Compiler 不做任何事，只是充当 JIT 编译器实现中的占位符。

26

The runtime uses a just-in-time (JIT ) compiler to convert the MSIL instructions to native machine code one method at a time as needed.

运行时根据需要使用实时（JIT ）编译器将 MSIL 指令转换为本机代码，每次转换一个方法。

27

An AOT-compiled method is also subject to JIT compilation , so after initial execution as AOT code , it may be optimised further by the JIT.

AOT 编译的方法仍然属于 JIT 编译处理的范围，所以在最初以 AOT 代码形式执行方法之后，JIT 仍然可以进一步优化它。

28

But the activity of the JIT compiler itself isn't the only source of unexpected variations in application-level timings .

但是 JIT 编译器本身的行为并不是应用程序计时中的意外偏差的唯一来源。

29

When dynamic methods are executed , the just-in-time (JIT ) compiler is called to convert the MSIL to native code .

执行动态方法时，会调用实时（JIT ）编译器将 MSIL 转换为本机代码。
