这种方式的缺点占用CPU并需要额外指令。
On the downside, this approach USES the CPU and requires additional MIPS.
这增加了编译器的工作，因为它必须生成这些簿记指令，同时增加了运行时环境的开销，因为它必须执行这些额外的指令。
This creates both work for the compiler, which must generate these bookkeeping instructions, and overhead for the runtime environment, which must execute these additional instructions.
同时这也导致了代码庞大，因为将函数参数保存在堆栈中需要额外的指令。
It also results in code bloat due to the extra instructions required to save function parameters to the stack.
该文件包含额外的服务器指令，每次请求包含 .htaccess 文件的目录时将加载并应用这些指令。
This file contains additional server directives that are loaded and followed on each request to the directory where the .htaccess file resides.
Ant在执行的过程中会忽略额外的处理指令，这样您就没有必要在一开始就单独生成HTML文件。
Ant will just ignore the extra processing instruction when executing, so you have no need to generate a separate HTML file first.
这样做不但会产生用于发送指令的额外通信开销，更会在节点数量上升时由于协同算法计算量上升，从而导致整个系统的效率下降。
This will bring the extra communication cost for instruction delivery, as well as the efficiency decrease because of the increase of computation cost brought by increased nodes 'numbers.
此外，IBM研究人员发现很多用于微代码计算机中较复杂的指令不需要额外硬件，仅被作为微代码程序被执行。
Further the IBM researchers observed that many of the more complex instructions available on most microcoded computers did not require extra hardware and were implemented only as microcoded routines.
处理更小和更大的数据类型有时需要额外的机器指令。
Manipulation of smaller and larger data types sometimes requires the use of additional machine-language instructions.
额外的空间允许的条件指令行开始忽略，但一个标签是不允许的。
Extra Spaces are allowed and ignored at the beginning of the conditional directive line, but a TAB is not allowed.
在加载更多的程序集并转化IL为机器指令时，CLR的加载器有一点额外的工作要完成，那就是调整函数入口地址。
The CLR loader has a little more work to do to load many assemblies and turn IL into machine instructions, particularly resolving function addresses.
