Application Binary Interface Overview

Yapay zekadan makale özeti

Basic Concepts: ABI defines interface between binary program modules, often libraries and user programs
ABI defines data access in machine code, unlike high-level API in source code
Compilers, operating systems, and library authors typically adhere to ABIs
Key Components: Specifies processor instruction set and data types
Determines parameter passing methods and stack organization
Defines system call conventions and binary formats
Can standardize platform-specific details like name mangling
Embedded ABIs: EABIs specify conventions for embedded software programs
Optimize performance within limited embedded system resources
Omit kernel-user code abstractions like dynamic linking
Widely used examples include PowerPC, Arm EABI, and MIPS EABI
Cross-Platform Features: Complete ABIs enable cross-platform compatibility with shared libraries
Some ABIs standardize platform-specific details like exception handling
EABI choice can significantly affect embedded system performance
