标准库（LSB）.第8-2部分:S390X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，并为安装脚本提供了一个最小环境。其目的是为符合 LSB 的高体积应用程序提供一个统一的行业标准环境。这些规范由两部分组成：描述所有 LSB 实现中保持不变的部分的公共部分，以及根据处理器架构不同的架构特定部分。共同部分和单个硬件架构的相关架构特定部分一起为在共享相同硬件架构的系统上编译的应用程序提供了完整的接口规范。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会使用更大的 ABI 集合。符合 LSB 的实现必须提供此处列出的所有 ABI。编译系统可以将某些 API 替换为对一个或多个底层二进制接口的调用，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。并非所有在源级别可供应用程序使用的 API 都包含在此规范中。这是 Linux 标准基 (LSB) 核心模块的 S390X 架构特定部分。该部分通过补充共同部分与架构之间不同的接口，对共同部分进行扩展。应将此部分与 LSB 核心 - 基本版本一起使用。每当共同部分的部分被架构特定信息补充时，共同部分中会包含对该架构特定部分的引用。此部分还可能包含未在共同部分中引用的其他信息。在此部分描述的所有 LSB 核心规范接口均为强制性的，除非另有明确说明。所有其他模块都依赖于 LSB 核心的存在。 [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 S390X 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.
