Author: tsoome Date: Sun Sep 8 19:39:45 2019 New Revision: 352032 URL: https://svnweb.freebsd.org/changeset/base/352032 Log: loader: --gc-sections needs sections to work with --gc-sections is not really useful unless we generate sections with -ffunction-sections -fdata-sections While there, i386/loader would win from --gc-sections too.
