摘要： Embodiments of a method and system for compiling code, such as program-generated code, are disclosed herein. The method and system efficiently encode combined range and stride checks. For example, the method and system are operable to encode combined range and stride checks as they occur in a translation of switch statements. The method and system can generate code to perform the range and stride check, and to branch to the case body, if the range and stride checks are successful. The various embodiments may operate to provide an efficient code transformation, better code density, and processing performance. Other embodiments are described and claimed.
摘要翻译：本文公开了用于编译代码的方法和系统的实施例，例如程序生成的代码。该方法和系统有效地编码组合范围和步幅检查。例如，该方法和系统可操作用于在组合的范围和步幅检查在开关语句的翻译中发生时进行编码。方法和系统可以生成代码来执行范围和步幅检查，并且如果范围和步幅检查成功，则分支到案例主体。各种实施例可以操作以提供有效的代码转换，更好的代码密度和处理性能。描述和要求保护其他实施例。

摘要： A system for performing code optimization is described which includes an optimizing analyzer within a compiler to generate a first optimizing transformation and a second optimizing transformation and their satisfying conditions for a compiled code. An optimization transformation module is placed within a linker to determine which of the first and second optimizing transformations should be selected when the compiled code is linked with other compiled codes, and to execute the selected one of the first and second optimizing transformations at link-time. A method of performing code optimization is also described.
