摘要： A method and computer program product for selecting an expression evaluation technique for domain-specific language (DSL) compilation. An application written in DSL for a programming task is provided, the application including a plurality of components configured by expressions. A technique that most quickly implements the programming task is selected from a plurality of techniques for evaluating the expressions. The DSL application is compiled in accordance with the selected expression evaluation technique to generate general-purpose programming language (GPL) code.

摘要： Method, system and computer program product for converting integers to floating point values in a data processing system. The method utilizes data flow analysis and control flow analysis to recognize that a particular integer that is to be converted contains only a limited range of values. Knowledge of this limited range is used to establish a table of floating point values indexed by the integer value. By using the table of floating point values, conversion of an integer to a floating point value can be performed faster and with reduced memory traffic.

摘要： An optimization mechanism in a compiler performs region-based code straightening to line up frequently executed basic blocks together based on profile directed feedback. The region-based code straightening lines up the basic blocks in order of execution sequence, but does not move infrequently executed basic blocks too far away from predecessors. As such, code locality is maintained, thus reducing instruction cache misses.
摘要翻译：编译器中的优化机制基于区域定向反馈，执行基于区域的代码整理，将频繁执行的基本块排队在一起。基于区域的代码校正以执行顺序的顺序排列基本块，但是不会将不经常执行的基本块移动到与前辈相距太远的基础块。因此，维持代码位置，从而减少指令高速缓存未命中。

摘要： An apparatus and method for removing stores to local variables that are not aliased by other variables or to variables which have already been removed by previous optimizations prior to performing dead store elimination optimization are provided. With the method and apparatus, instructions that include a memory reference to a local variable that is not modified by other instructions are identified. For these instructions, an identifier of the variable referenced is maintained in a data structure along with the location of the store instruction in the procedure (for a store instruction) or a load indicator (for a load instruction). The data structure is then traversed to see if there are any store instructions referencing a variable that does not have a corresponding load instruction referencing the same variable. Such store instructions are eliminated prior to performing traditional dead store elimination.
摘要翻译：提供了一种用于将存储器移除到不被其他变量别名的变量或已经在执行死存储消除优化之前已被先前的优化所去除的变量的存储的装置和方法。利用该方法和装置，识别包括对未被其他指令修改的局部变量的存储器引用的指令。对于这些指令，引用的变量的标识符与程序（用于存储指令）或负载指示符（对于加载指令）的存储指令的位置一起保持在数据结构中。然后遍历数据结构以查看是否存在引用不具有引用相同变量的相应加载指令的变量的存储指令。在执行传统的死区消除之前，消除了这种存储指令。
