His article covers the core operating principals of Microsoft's implementation such as the machine code used by compiled regular expressions.
他的文章谈及了微软实现中的一些核心操作原理，如编译正则表达式时使用的机器码。
Under normal circumstances a function will only be inlined if the resulting machine code is smaller than the original version at the call site.
在常规情况下，函数只有当在调用空间中的结果机器码比原始版本要小时，才能被内联。
The Numbers in the left column are the memory locations where the machine code is located. The corresponding assembly language is in the right column.
左列的数字代表机器码所在的内存地址，右边的列代表相应的汇编语言。
A running JVM executes bytecode by translating it on the fly into machine code that its host will understand, a process called just-in-time compilation.
运行中的JVM靠快速把字节码转换成宿主能理解的机器码执行字节码，这个过程叫即时编译。
First, you shouldn't assume that the above assignment would be compiled as a single machine instruction unless you personally verify the machine code yourself.
首先，不应该假定上述赋值语句一定会被编译成一条机器指令，除非亲自验证了机器代码。
A sequence of machine code instructions stored within the operating system, and sometimes in read-only memory, which is used to simulate hardware functions.
一组机器代码指令，存放在操作系统内，有时也存放在只读存储器中，用来模拟硬件的一些功能。
Because of our JIT technology, we can offer performance higher than MacRuby as well because we can take advantage of profiled information to generate faster machine code.
由于我们独特的JIT技术，我们能够提供比MacRuby更加优异的性能。这项技术能够高效地利用程序剖析信息，从而产生更加快速的机器代码。
As you saw in the December installment, the HotSpot JVM first executes a code path in interpreted mode, and only compiles it to machine code after a certain amount of execution.
在12月份的文章中可以看到，HotSpotJVM首先以解释的方式执行代码路径，然后在经过一定量的执行后，才将其编译成机器代码。
But while the Python interpreter is running an application, Psyco sometimes checks to see if it can substitute some specialized machine code for regular Python bytecode actions.
