Basic Concepts

UNIX ABI (Application Binary Interface)

  • ABI defines a binary interface for application programs that are compiled and packaged for System V implementations on many different hardware architectures
    • generic ABI: parts of the interface that remain constant across all hardware implementations of System V
    • processor-specific ABI: parts of the specification that are specific to a particular processor architecture
      • Data representation
      • Function calling sequence (e.g. i386)
        • %eax: return value
        • %esp: stack pointer
        • %ebp: stack frame pointer
