Author: mmel Date: Wed Apr 29 14:06:42 2020 New Revision: 360463 URL: https://svnweb.freebsd.org/changeset/base/360463 Log: Don't allow to use FPU inside of rtld library. Clang10 may use FPU instructions for optimizing operations with memory blocks. But we don't want to do lengthy save/restore of all FPU registers across each rtld_start() call.
