标准库（LSB）.第6-2部分:PowerPC64体系结构的核心规范

[中文适用范围]： Linux标准基（LSB）定义了一个编译应用程序的系统接口和一个支持安装脚本的最小环境。其目的是为高卷积应用提供统一的行业标准环境。这些规范分为两部分：一部分描述所有实现中保持不变的部分，另一部分描述根据处理器架构变化的接口。共同部分和特定硬件架构的相关部分一起为共享相同硬件架构的系统上的编译应用程序提供完整的接口规范。LSB包含一组应用程序编程接口（API）和应用程序二进制接口（ABI）。API可能出现在可移植应用程序的源代码中，而编译后的二进制文件可能使用更大的ABI集合。符合要求的实现应提供在此列出的所有ABIs。编译系统可能会通过宏定义等方式替换某些API调用底层二进制接口，并在需要时插入对二进制接口的调用。LSB主要是一个二进制接口定义。并非所有可用于应用程序的源级别API都包含在此规范中。这是Core模块中的PPC64架构特定部分，它补充了LSB Core模块的公共部分中那些因架构而异的部分。此部分应与LSB Core - Generic（公共部分）一起使用。每当公共部分中的某一部分被架构特定信息补充时，公共部分将包含对架构特定部分的引用。此部分也可能包含未在公共部分引用的信息。在此部分中描述的LSB核心规范接口是强制性的，除非另有明确规定。在LSB Core模块中描述的接口由其他LSB模块补充。所有其他模块都依赖于LSB Core的存在。 [外文原描述]： This document defines a system interface for compiled applications and a minimal environment for support of installation scripts. Its purpose is to enable a uniform industry standard environment for high-volume applications conforming to the LSB. These specifications are composed of two basic parts: a common part describing those parts of the interface that remain constant across all implementations of the LSB, and an architecture-specific part describing the parts of the interface that vary by processor architecture. Together, the common part and the relevant architecture-specific part for a single hardware architecture provide a complete interface specification for compiled application programs on systems that share a common hardware architecture. The LSB contains both a set of Application Program Interfaces (APIs) and Application Binary Interfaces (ABIs). APIs may appear in the source code of portable applications, while the compiled binary of that application may use the larger set of ABIs. A conforming implementation provides all of the ABIs listed here. The compilation system may replace (e.g. by macro definition) certain APIs with calls to one or more of the underlying binary interfaces, and may insert calls to binary interfaces as needed. The LSB is primarily a binary interface definition. Not all of the source level APIs available to applications may be contained in this specification. This is the PPC64 architecture specific part of the Core module of the Linux Standard Base (LSB). This part supplements the common part of the LSB Core module with those interfaces that differ between architectures. This part should be used in conjunction with LSB Core - Generic, the common part. Whenever a section of the common part is supplemented by architecture-specific information, the common part includes a reference to the architecture-specific part. This part may also contain additional information that is not referenced in the common part. Interfaces described in this part of the LSB Core Specification are mandatory except where explicitly listed otherwise. Interfaces described in the LSB Core module are supplemented by other LSB modules. All other modules depend on the presence of LSB Core.
