标准库（LSB）第3-2部分:IA64（安腾）体系结构的核心规范

[中文适用范围]： Linux 标准库 (LSB) 定义了已编译应用程序的系统接口以及支持安装脚本的最小环境。其目的是为符合 LSB 的大容量应用程序提供统一的行业标准环境。这些规范由两个基本部分组成：一个通用部分，描述接口中在所有 LSB 实现中保持不变的部分；以及一个特定于体系结构的部分，描述接口中因处理器体系结构而异的部分。通用部分和针对单个硬件体系结构的相关特定于体系结构的部分共同为在共享通用硬件体系结构的系统上运行已编译应用程序提供了完整的接口规范。LSB 包含一组应用程序接口 (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，而该应用程序的编译二进制文件可能使用更大的 ABI 集。符合 LSB 的实现提供了此处列出的所有 ABI。编译系统可以用对一个或多个底层二进制接口的调用替换（例如通过宏定义），并且可以根据需要插入对二进制接口的调用。 LSB 主要是一个二进制接口定义。并非所有应用程序可用的源代码级 API 都包含在本规范中。这是 Linux 标准库 (LSB) 核心模块中针对 Itanium™ 架构的特定部分。此部分补充了 LSB 核心模块的通用部分，其中包含了不同架构之间不同的接口。此部分应与通用部分“LSB 核心 - 通用”结合使用。每当通用部分的某一部分补充了架构特定信息时，通用部分都会包含对该架构特定部分的引用。此部分还可能包含通用部分中未引用的附加信息。除非另有明确说明，否则 LSB 核心规范此部分中描述的接口均为必需接口。LSB 核心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 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 Itanium™ 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.
