Author: emaste Date: Thu Jan 21 20:44:21 2016 New Revision: 294530 URL: https://svnweb.freebsd.org/changeset/base/294530 Log: Add STB_GNU_UNIQUE symbol binding definition Red Hat created STB_GNU_UNIQUE to handle certain special cases relating to dynamically loading C++ DSOs[1]. We don't (currently) have support for STB_GNU_UNIQUE, but ought to reserve the value in ELFNN_ST_BIND. This will also be used by an upcoming ELF Tool Chain import.
