Author: imp Date: Thu Jan 1 02:00:04 2015 New Revision: 276488 URL: https://svnweb.freebsd.org/changeset/base/276488 Log: Fix module builds on arm (and maybe others) by turning off a whole raft of new warnings that appear to be on by default in clang 3.5.0. Fix RPI-B build issues with new clang not liking the ability to pass arbitrary flags to as, since some flags are more arbitrary (and thus verboten) than others. These warnings should be actually fixed in the code, but this is a band-aide to get things (almost) building again.
