Author: emaste Date: Mon Jul 25 14:35:14 2016 New Revision: 303295 URL: https://svnweb.freebsd.org/changeset/base/303295 Log: MFC r301974: ar: enable reproducible output by default when invoked as 'ar -s' ar output is already deterministic by default for ar -q and ar -r, and when invoked as ranlib. Make ar -s equivalent to ranlib and enable deterministic output by default in that case too.
