<para>The Executable and Linking Format (ELF) defines a linking interface for executables
|
|
|
|
and shared objects in two parts: the first part is the generic System V ABI, the second part
|
|
|
|
is a processor-specific supplement.</para>
|
|
|
|
<para>This document, the OpenPOWER ABI for Linux Supplement for the Power Architecture 64-bit ELF
|
|
|
|
V2 ABI, is the OpenPOWER-compliant processor-specific supplement for use with ELF V2 on 64-bit
|
|
|
|
IBM Power Architecture® systems. This is not a complete System V ABI supplement because it
|
|
|
|
does not define any library interfaces.</para>
|
|
|
|
<para>This document establishes both big-endian and little-endian application binary
|
|
|
|
interfaces. OpenPOWER-compliant processors in the 64-bit Power Architecture can execute
|
|
|
|
in either big-endian or little-endian mode. Executables and executable-generated
|
|
|
|
data (in general) that subscribes to either byte ordering is not portable to a system running in the
|
|
|
|
other mode.</para>
