查询词典 compiler

Based on a lot of experiment results, a conclusion is drawn: comparing with other factors, the performance of branch handling strategy is the key limits of processor to exploit the instruction level parallelism existed in nonscientific code, cache miss have severe effect on superscalar processor's performance when it runs scientific code. Second, in order to reduce the branch penalty and improve the performance of superscalar processor, a new branch handling strategy—a classification based hierarchical branch handling strategy, CHBHS is proposed. It first expands the traditional processor architecture to support multiple condition code, conditional execution and Mbranch instruction, as a result, compiler can reduce the number of static conditional branch when the code is generated. Then, CHBHS tries to use the best suitable mechanism to deal with different branch base on their different behavior. CHBHS can predict the target address of unconditional branch, subroutine call and conditional branch by buffering their target address in branch target buffer, a newly proposed high efficient return address stack is used to reduce the penalty of subroutine return instruction, a new Counter Register Stack is also proposed to reduce the penalty of loop-closing branch to zero, and dynamic branch predictor is incorporate with branch target buffer to predict the outcome of conditional branch.

基于上述结论，为了尽量消除转移指令对处理器开发指令级并行性能力的影响，进一步提高处理器性能，在详尽分析目前已存在的转移处理策略的特点与局限性的基础上，首次提出了一种新的转移处理策略即基于分类的层次转移处理策略CHBHS(Classification Based Hierarchical Branch Handling Strategy)，它首先通过扩展传统的体系结构，支持多条件码、条件式执行及多分支转移技术，以使编译程序在进行代码生成时可尽量少生成条件转移指令，从而减少静态条件转移指令的数目；其次，基于不同的转移指令的行为不同这一事实，提出了对不同的转移指令采用不同的机制进行处理的思想，即对无条件转移指令和函数调用指令以及条件转移指令的目标地址，采用转移目标缓冲器来预测，对于函数返回指令，采用所提出一种的高效返回地址栈来预测其目标地址，对于大多数循环控制转移指令，采用所提出的Counter Register Stack来将其所可能带来的损失减少为0，对于其他的条件转移指令采用动态预测机制来预测其方向。

While loops the compiler never has to worry about whether the loop's conditional statement is expected to be satisfied or not in the first run.

当程序中包含了一个do…while循环时，编译器会生成一个比上面的例子简单的多的代码流。

There is no requirement that the compiler lay out the base and derived parts of an object contiguously. Hence, Figure 15.1 is a conceptual, not physical, representation of how classes work.

C++ 语言不要求编译器将对象的基类部分和派生部分和派生部分连续排列，因此，图 15.1 是关于类如何工作的概念表示而不是物理表示。

For example, variable length arrays [2, 3, 4, 5] came from the Cray C compiler, and a similar feature is in GNU C.

例如，变长数组 [2， 3， 4， 5] 来自 Cray 的C编译器，以及GNU C中一个类似的特性。

CrissCross crossword compiler is an ideal tool for education.

交错纵横的编译器是一个理想的工具，教育。

Much fun and success with CrissCross crossword compiler!

很多的乐趣和成功与纵横交错的填字谜编译器！

That is because there is no ASCII equivalent special character, so the regular expression compiler already knew you meant a decimal digit.

这是因为ASCII里没有等价的特殊字符，所以正则表达式编译器已知道你的意思是一个十进制数字。

This is an example of declarative information; it's nice because of the economy of expression and because the compiler handles the details for us.

这是一个声明信息的一个例子，是一件好事，因为经济和表达，因为编译器为我们处理的细节。

The compiler supports use of a function declarator that specifies a variable number of arguments, followed by a function definition that provides a type instead

编译器支持使用指定可变个数参数的函数声明符，其后为提供替换类型的函数定义

We have two option, either use the compiler switch /Zp or use #pragma statement before declare the structure.

我们有两个选择，要么使用编译器开关/ Zp上或使用＃pragma语句之前宣布的结构。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
