Application Binary Interface for the Arm Architecture introduction
This document describes the structure of the Application Binary Interface (ABI) for the Arm architecture, and links to the documents that define the base standard for the ABI for the Arm Architecture.
-
Procedure Call Standard for the Arm Architecture
This document describes the Procedure Call Standard use by the Application Binary Interface (ABI) for the Arm architecture.
-
ELF for the Arm Architecture ABI
This document describes the processor-specific definitions for ELF for the Application Binary Interface (ABI) for the Arm architecture.
-
DWARF for the Arm Architecture
This document describes the use of the DWARF debug table format in the Application Binary Interface (ABI) for the Arm architecture.
-
Base Platform ABI for the Arm Architecture
This document describes the Base Platform Application Binary Interface for the Arm architecture. This is the base standard for the interface between executable files (including dynamic shared objects, DLLs, etc) and the systems that execute them.
-
C++ ABI for the Arm Architecture
This document describes the C++ Application Binary Interface for the Arm architecture.
-
Exception handling ABI for the Arm Architecture
This document describes the exception handling component of the Application Binary Interface (ABI) for the Arm architecture. It covers the exception handling model, encoding in relocatable ELF files, language independent unwinding, and C++ specific aspects.
-
Run-time ABI for the Arm Architecture
This document defines a run-time helper function ABI for programs written in Arm-thumb assembly language, C, and C++.
-
C Library ABI for the Arm Architecture
This document defines an ANSI C (C89) run-time library ABI for programs written in Arm and Thumb assembly language, C, and stand alone C++
-
Support for Debugging Overlaid Programs
This specification defines an extension to the ABI for the Arm Architecture to support debugging overlaid programs. No tool chain is required to support this extension but tools that support debugging overlaid programs should do so in one of the ways specified in §3.
-
Addenda to, and Errata in, the ABI for the Arm Architecture
This document describes late additions (addenda) to the ABI for the Arm Architecture version 2.0, and errors (errata) discovered in it after publication.
