Author: imp Date: Thu Aug 27 23:46:42 2015 New Revision: 287227 URL: https://svnweb.freebsd.org/changeset/base/287227 Log: Use CFLAGS_NO_SIMD in preference to varying lists of -mno-xxxx flags. Go ahead and defined -D_STANDALONE for all targets (only strictly needed for some architecture, but harmless on those it isn't required for). Also add -msoft-float to all architectures uniformly rather that higgley piggley like it is today.
