Binary interfaces between system and application components are defined to enable the asynchronous evolution of these facilities. The Oracle Solaris link-editor and runtime linker operate upon these interfaces to assemble applications for execution. Although all components handled by the Oracle Solaris link-editor and runtime linker have binary interfaces, the whole set of interfaces provided by the system is referred to as the Oracle Solaris ABI.
The Oracle Solaris ABI is a technological descendent for work on ABI's that started with the System V Application Binary Interface. This work evolved with additions performed by SPARC International, Inc.® for SPARC processors, called the SPARC Compliance Definition (SCD).
