Chapter 7 - FORMATS AND PROTOCOLS

ABI Version Identification

An ABI-conforming system which conforms to revision 1.2 or later of the ABI Conformance Guide will have an ASCII file which identifies the highest revision level to which the system conforms.

The version file is named /etc/mipsabiversion.

The file contains a newline-terminated string of the form major.minor. Only the first line should be processed; all subsequent lines should be ignored. Sub-versions (e.g., the.1 in 1.0.1) are not reflected in the version file as they only reflect clarifications to the wording in a baseline spec.

If the file is not found, the system should only be assumed to be conformant to a Conformance Guide revision prior to 1.2 - it is not possible to distinguish between revision 1.0 and revision 1.1.
