Linux Standard Base (LSB)

Go to the LSB specifications page.

Application Programming Interface (API) Standards

• Single UNIX Specification version 2, OpenGroup
• Single UNIX Specification version 3, OpenGroup

DWARF Standards

Several versions of the Debugging With Arbitrary Record Formats (DWARF) Standards can be found here.

The latest version of this standards is 3.0, and can be found here. The older version is still in widespread use, and is part of the Current LSB.

• DWARF version 2.0 Previous Standard
• DWARF version 3.0 Current Standard

ELF and ABI Standards

The Executable and Linking Format (ELF) Specification describes the widely used executable file format. The Application Binary Interface (ABI) Specifications define Operating System and Application interfaces that are neccesary to construct an execution environment for applications.

• Tool Interface Standard (TIS) Portable Formats Specification, version 1.1. 1993 document containing an extract of the x86 ABI version 3.0, DWARF 2.0 draft and OMF
• Tool Interface Standard (TIS) Portable Formats Specification, version 1.2. 1995 document containing only the ELF Specification. This version breaks ELF into 3 seperate books, ELF, x86 psABI, and the Operating System Specific Specification for SVR4. This appears to be the most current TIS specification.
• System V ABI Edition 4.1. 1997 document containing the most recent ABI standard. This document is known as the Generic ABI (gABI) and must be used in conjunction with a Processor Suppliment aBI (psABI) document.
• System V ABI - DRAFT 24 April 2001. 2001 update to chapters 4 and 5 of the gABI. This version is the most recent work and is widely used, however it does not appear to hae been formally released as a standard.

Processor Specific ELF documents

• System V Application Binary Interface Intel386 Architecture Processor Supplment, Fourth Edition
• Intel Itanium Processor specific ABI
• System V Application Binary Interface x86-64 Architecture Processort Supplement Draft Version 0.95
• System V Application Binary Interface MIPS RISC Processor Supplment, 3rd Edition
• System V Application Binary Interface PowerPC Processor Supplment. This is one of two known PPC ELF standards. This one was developed by SunSoft. The two versions are not identical, and applications can only conform to one or the other, while it seems possible for an implementation to support both simulaneously.
• ARM Processor Supplment
• Processor-Specific ELF Supplement for PA-RISC
• Motorola 8 and 16 bit Embedded ABI
