New Revision: 360605
URL: https://svnweb.freebsd.org/changeset/base/360605
Log:
MFC r352032 (by tsoome):
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.
