Author: imp Date: Wed Aug 26 17:10:43 2015 New Revision: 287167 URL: https://svnweb.freebsd.org/changeset/base/287167 Log: After consultations with the arm community, don't define softfp for armv6. It's too ambiguous. We do use the softfp ABI for the moment on armv6, but we allow floating point register use (and the compilers will generate it). This is too ambiguous to use it as a decider for which algorithms to use on the platform. Err on the side of caution and not define it.
