The ABI (application binary interface) specification provides the definitions for the machine interface and
inter-object interfaces for the little-endian POWER architecture.

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.
ERRATA:
An OpenPOWER ELFv2 Errata: For ELFv2 ABI Version 1.4 has been published. These errata should be considered part of this specification until such time as a newer version of the full specification is published.
