Author: kan Date: Fri Apr 7 22:58:25 2017 New Revision: 316625 URL: https://svnweb.freebsd.org/changeset/base/316625 Log: Do not use -msoft-float with intention of disabling FP on aarch64 GNU GCC does does recognise it as a valid option and we already use -mgeneral-regs-only that has the desired effect.
